Accidental deletion of valuable file from our computer is not new. This problem is as old as computer itself is! And this mishap happened to me few days back when I accidentally deleted one of my most crucial doc files. However, thanks to efficient file recovery software for recovering my doc file well on time!
Being a content writer with a traveling company, I need to write web content for various web sites of organization and to do my job I use Microsoft Word 2003 as text editor. Recently, I had been assigned web content on an urgent basis. Thanks to God that I met the target just on time but before submitting it, I found that a large number of temp copies of that particular file were created there. Thus, due to the pressure to submit the target on time and to delete the temp copies, I accidentally pressed ‘Ctrl+A’ and ‘Shift+Delete’ button. Alas! I lost my precious doc file just in one go.
Furiously, rushed to my senior and explained the situation to him. He calmed me down and explained that recovery of lost or deleted files is possible through efficient file recovery software. However, for successful recovery of my valuable doc file, he asked me to stop using my computer immediately. The reason for saying so was that whenever we delete a file from the hard drive of computer, it is not actually deleted rather the pointer to this file gets deleted and the space occupied by this file is marked as free. However, this free space is inaccessible by operating system but reliable third-party recovery software can read the data without the pointer and thus can recover it. But, when a new file/data is saved on the hard drive of computer then it occupies this free space and then deleted the file may go beyond the recovery. Therefore, it is recommended to not to use the effected hard drive until the data is been recovered.
However, he suggested me to use Stellar Phoenix File Recovery Software for successful recovery. This efficient software can recover the files which are lost due to accidental deletion or formatting of the hard drive. The software supports recovery of 185 file types. Therefore, as per his recommendation, I used this software and in few simple recovery steps recovered my deleted doc file. Once again I would like to say thanks to this effective file recovery software.
Advanced and pervasive virtualization and cloud computing trends are driving the need for a better, holistic approach to IT support and remediation.
And while the technology to support and fix virtualized environments is essential, it’s the people, skills, and knowledge to manage these systems that provide the most decisive determinants of ongoing performance success.
In a special BriefingsDirect sponsored podcast, created from a recent HP Expert Chat discussion on best practices for VMware environment support, HP experts explain how they have made the service and support of global virtualization market leader VMware a top priority.
For example, Cindy Manderson, Technical Solutions Consultant for Complex Problem Resolution and Quality for VMware Products at HP, provides case studies for how managed escalation and multi-vendor support around the globe can reduce downtime by 70 percent, with large ROI benefits as well.
Other HP experts in the discussion include Pat Lampert, Critical Service Senior Technical Account Manager and Team Leader, as well as Sumithra Reddy, HP Virtualization Engineer. The discussion is moderated by Dana Gardner, Principal Analyst at Interarbor Solutions. [Disclosure: HP and VMware are both sponsors of BriefingsDirect podcasts.]
Here are some excerpts:
Gardner: Virtualization isn’t just server-by-server, but really impacts the entire data center. You need to think about it more holistically, particularly in regard to things like security, performance and how your brands and businesses are perceived across the globe. Many of the companies that I deal with day in and day out are up at 80 percent and even 90 percent virtualized.Listen to the podcast. Find it on iTunes/iPod.

When they think about virtualization, they go beyond just server virtualization. It’s really now looking at storage, applications, networks and even the end-user desktop experience, or desktop as a service (VDI).
Successful virtualization is no longer just about servers, it’s about managing complexity when you get beyond the 20 percent or 30 percent level and expand into converged infrastructure virtualization without failures.
So how to take advantage of the best things about virtualization? Part of that means allowing your IT team to have access to other experienced support teams, from HP and VMware, around the world, 24×7, to help keep systems up and running. Such support also allows your IT team to progress, to learn as they go, and to be able to take advantage of more virtualization benefits over time.
Expert panel
So how do you go about attaining such benefits? How do you keep the positive side of virtualization on track? And how do you put in place an insurance policy around service and support?
Manderson: We have several different packages. Our highest level is the mission-critical. In this particular process, you're assigned a team that are across the technology that you have in your environment. But you also get a set of folks who would actually look at not just the reactive support and even some of the proactive, but how actually your entire business is running according to the ITIL standard.
That is coupled with keeping you up and running, and we also can work with you on a type that would be best suited for your environment.
Our critical and independent support includes onsite resources from HP that also include a lot of proactive support. In addition, they're more focused on specific management, but that would be more of an ITSM technology. We can look at that for you.
... We also have the hardware and software support. One of the cool things we have with our hardware support is support automation, our Insight for remote support. That can notify HP that you're having a disk drive failure. Or we will call you and say that we know that disk drive is failing, or something on a buffer server and storage is about to.
You can even take that a step further to look inside at the Windows operating system. We're hardware agnostic on that operating system. We don't care about the vendor -- and I believe we are looking at expanding that automation to other operating systems. We have installation and startup services that we can actually go out and set up and configure the hardware and software at a site.
So we definitely integrate across all the multi-vendor services. We run the gamut between all the x86 operating systems, as well as our proprietary operating systems, our servers and storage. Again, we're no stranger to multi-vendor support and keeping the entire environment up and running.
... One of our most creative services would be Proactive Select, a core product series of credits. You can use these credits for maybe planning on migration and upgrade. You can say you need some consulting time. You can use these credits and work with upgrade and migration. You may need some performance or you may need some type of environmental assessment, and these credits can be used for that.
Gardner: When people do employ these services, how do they measure what the payoff is, the value of these services?
IDC study
Manderson: In 2010, IDC did a study. They went out and looked at the methodology, and this is out on our website. They saw that the customers who have the mission-critical services, reduce their downtime by over 70 percent, and increase their return on investment (ROI) quite high, over 400 percent. The main benefit was in problem management as well as help desk calls, because these were alleviated due to the proactive nature, a lot of looking at the entire environment, and looking at the business processes.
So take a look at the study. It shows IDC's methodology. So looking at things proactively and these support processes can certainly help you reduce that downtime.
... I've been in the multi-vendor space for many, many years -- from applications to operating systems -- all with HP.
In 2002, when VMware came on the scene, HP actually became alliance partners with them. In 2003, we became a reseller, and thus began our support partnership with them. It would only extend recent in 2005, we also became an OEM. We have thousands of trained and certified Microsoft engineers and Linux professionals, too.
But we have the largest number of VMware-certified professionals. We're also have the largest global VMware off-site training center. So HP also does education on these technologies as well. We’ve trained over 20,000 students in the VMware space alone.
And we have had this very strong collaboration with VMware for many years and have support teams around the globe. In addition, we also offer the same level of training that VMware support engineers do. We actually go to their facilities and train right alongside them, too.
We further do this training virtually. The training is then recorded and made available on demand for reference, for folks who are not able to attend a scheduled course. There's definitely a very strong partnership, and as you see from our history with the other vendors as well as VMware, we are no strangers to multi-vendor support.
With all of the VMware products that HP sells, we do provide support across them all. It runs the gamut from the vSphere operating system that will install on the x86 server, through the enterprise management to the vCenter, and virtual desktop infrastructure products like VMware ThinApp. We also support the converter product getting into vCloud Director.
In addition to that, we have the ability to access our peers on the other teams across HP hardware support. This includes servers and storage, and our networking chain. We are quickly able to collaborate with them and pull together a virtual team in to focus on the customer's whole environment, to provide a one-stop shop.
Expertise across technologies
Additionally, you saw that we’ve been in this multi-vendor support business for so many years, with many experts across the other technologies, such as Microsoft and Linux. Of course, the virtual machines (VMs) are running these operating systems. So if the contract is also with them, we can easily pull them in to help us work an end-to-end solution and support it.
Gardner: Let’s think about what happens when there are different levels of support at work. How does that shake-out?
Manderson: We're in a reactive support business. If the customer has a problem, they can either call in at their local region telephone number -- whether they are in America, Europe, or Asia Pacific. There are different phone numbers for them to call.
They can also log in via the web, and they'll get to our next developer Level 1 engineer. They're a great organization and have solved over 85 percent of their cases.
If they have issues where they have to escalate, first they will be collaborating with us. We also have an online chat tool, where we are all in a virtual room, the Level 1 engineers, Level 2 engineers, etc. So we’ll be consulting and collaborating with them before they even get to a point of escalation.
If the case does end up needing escalation, chances are they're already collaborating with the first person, and will then end up taking the case. That saves a lot of information transfer, as far as what type of server you have, what’s the firmware, what build level, and what’s the problem there, etc.
Once it reaches Level 2 support, as far as we can continue to collaborate, we can reach our teammates and the hardware teams, too, so we can look at the server and make sure that the environment is what we need it to be. If we can't resolve it, we can also go to Level 3 with VMware at an offline service-partner level.
We have a great relationship with the folks that we work alongside with and would escalate calls to at VMware. We’re obviously not going into Level 1 at VMware because we’ve already done all that work, and we are a service partner. They'll go right up to our peers over at VMware and then we work together, while always owning the solution that we provide back to the customer.
Another part of our infrastructure-as-a-support-organization is that we have a single customer database. I can give an example. A call came into our Level 1 French engineer. When this call came in, for the European folks, it was already the end of their day, and the French engineer could not speak English. It was a critical down, their VMs were offline.
HP Virtual Room
So we worked in a virtual room and they talked to us, and brought the case to us here in America’s time zone. We worked with this case and another tool called HP Virtual Room, where we could actually all look at the customers' desktops in real time. They happened to have EVA storage, and we quickly got an EVA engineer engaged. Of course, we had to find a resource in the Americas because the European folks had already left. So we're all looking in real-time at the customer’s environment and found out that they had locked the storage.
The EVA engineer helped to get back online, while we all watched and the French engineer was translating in French for the customer in order to get it all resolved. We got it back online, and the customers were ready to home.
We gave instructions on getting log files and we placed a call for follow-up for the daytime hours in Europe the next day. So our counterparts in European support teams picked that up and worked with the customers to resolution, to analyze exactly what happened and prevent it in the future.
We have another process in HP that can actually go with top organizations, our escalation manager process. I was lead source for a particular case where we had a field team assisting a customer deploying a virtual desktop infrastructure (VDI) design. They had a third-party VDI vendor. They had HP hardware, servers, and virtual connects. They had our storage, and we didn’t quite know where the bottleneck was. They were having performance issues by trying to have this VDI at two different locations with the hardware at one site.
The escalation manager was able to get the local office to borrow equipment, and then try to get performance and network traces. They had the Engineering Problem Management Resource (EPMR) lab in Houston trying to duplicate the problems.
Our escalation manager was able to drive the issue to completion across not only the solution standards, but the local office, to owning the actual escalation with all the action items to keep this all on track. We knew where we were going to go. That was about a six-month case, but we did finally find was that the customer was on the technological edge, and the "pipe" to have that performance just did not exist.
Site visits
Pat Lampert is a technical account manager and does site visits. The technical account managers do go out on site. So we’re aware of the environment. We have the information of your environment documented into the database. When you call, we’re not saying, "Now what kind of server is this? What’s the firmware?" We know this because we already have it documented. We could be calling them to say, "Server 3 is running a little off." We already which know VMware version this is on, because we have that information.
And because we have that, we can also offer proactive advice. We can know that there's a new firmware update, or VMware just came out with a new build, and we have a place where you can go find the latest that's specific to your environment. So this helps to reduce further incidents, because we can be more proactive to help you maintain your business.
Gardner: What are some of the the most frequent questions you receive from the field?
Reddy: I'll address two questions that are frequently showing up. One is, what is the difference between the VMware ESXi image and an HP ESXi image?
Basically, HP takes the same ESXi image that VMware provides to the customers. It then adds HP thin components for hardware management, and it also adds any latest fibre channel and network drivers. Once it's tested and certified, it's available for download both from HP and VMware websites.
Major differences
And one of the major difference between the two images is that VMware image is disk installable only, whereas HP image can be installed on a disk, USB key, or a SD card.
The other question we're getting nowadays is how to upgrade from VCA4 to VCA5. As with any major upgrades, planning helps. The first thing I would do is understand the difference between ESX 4 and ESX 5, because starting with ESX 5, we have no service console. So we need to understand what the architectural differences are.
Also learn about the new licensing policies. Then, use the System Analyzer that VMware provides to evaluate the current environments, and download, check, and complete the checklist. Once this is done, hopefully the upgrade will go smoothly.
Lampert: Another question that has come up from customers has to do with the added value of getting support directly from HP. It was partly addressed during the presentation we just gave. First of all, VMware does have a fine support organization. I have a couple of friends who work in VMware Support, and they do a good job of supporting their product.
HP, in addition to a similar level of expertise in the product, also offers our expertise in HP hardware, especially if you have systems based on HP Blades. The infrastructure behind that often is tied very closely to the performance and availability of your ESX host. So when you call us, you will have not only someone who is very familiar with the VMware product, but also is familiar with the HP hardware and able to pull in the proper resourced results, problems you might encounter with running vSphere on HP hardware especially.
In addition to that, we have a partnership agreement with VMware, and when you call in for support through HP, you're getting that same level of service when we have to go to VMware to get answers to questions or fixes.
One other question that has come up is about our lab ability to reproduce problems. We have two global labs, one in India and one in the United States. We have several static vSphere cluster configurations with a number of different types of servers already in those configurations, and the ability, when needed, to add specific models, if there is a problem that’s specific to a particular Blade or rack-mounted server model, or a particular card or something like that. So we're quite able to reproduce most problems that come in. We even have some Dell and IBM equipment in our lab also.
Gardner: What other issues are users grappling with?
Reddy: One question I can answer is how to troubleshoot server crashes. When something goes wrong in ESX, we call it the "Purple Screen of Death." Often, these are results of hardware failure, but we still need to rule out the software. So we collect all the logs, and look at it to see if it's a software issue. If it's not a software issue, then we engage the hardware team to see how we can get to the root cause and fix the issue.
Lampert: To dovetail with Sumithra’s comment there, one of the questions I get frequently is what to do if you don’t have a dump. Say the host hangs, and that seems to be almost more common than the Purple Screen of Death. Some customers are't aware that through HP’s Integrated Lights-Out Management, there is the ability to generate a non-maskable interrupt (NMI) just by pressing a button, and by saving a certain environment variable ahead of time in your ESX host.
KB article
There is a KB article on this, by the way, if you just search on NMI and core dumping in VMware. But with that setup, you can force a dump while a system is in a hung state, and that will assist us usually in troubleshooting and isolating what caused the hang, whether it be hardware or a problem with the ESX host software.
One question that came up ahead of time is what HP suggests as far as getting a handle on our inventory of VMs? I happened to be involved in field testing some new tools from HP that will be available in January and February regarding vSphere.
One of them is a Holistic Blade and Firmware Analysis that takes into account the VMware environment on our Blade systems which we are working on having ready soon. We have just completed field tests.
And the second is a really nifty Inventory Report HP has just put together. We're just completing field tests on that now. It will be available soon. Basically, we install a small Perl script in the customer environment on any machine that has access to the vCenter host and has a vSphere CLI installed.
This Perl Script crawls through the VMware environment and builds an XML file, which we then feed into a report generator here at HP. This can be used for us to gather information on customers, so we have ahead of time a clear picture of the environment. But also it will be sold as a service to customers.
The report is really quite nice, with all sorts of charts and showing availability of machines and availability of memory and also disk space. It's a very nice report.

The Importance of Having a Robust Backup and Recovery System in Tech and Business News
Posted by Leo Alvin Alexander Jan 18, 2012Everyone should have a solid Backup and recovery system so that they are prepared if an outage occurs. It is easier to get back to normal operations when you have a backup plan set up properly. Not everyone is familiar with the process involved in coming up with a good recovery plan, but everyone understands the need to have a backup plan in case they ever lose their data. This understanding only becomes clearer after you have lost data. Numerous IT companies work to make sure this never happens to you and they will assist you in coming up with a plan. However, to get a clear overview of what has needed, let us look at the basic steps involved.
Disaster Backup and Recovery plans are only effective when data is fully backed up; there are many steps one can take in order to have a working system. One involves practicing the recovery process to see if it works well and then making sure to save crucial information like passwords and such on a document. This document should be kept safe, copied and stored in multiple locations. If you have ample staff, you may need to let key trustees know of these locations.
Data storage has always had its challenges and the most common is data corruption and loss due to viruses and external attacks. Internet security is needed when using Cloud Backup as many people do. For the Backup and Recovery process to work efficiently, the third party Cloud Backup service provider has to have sufficient security that will help protect the data and make automatic backups of the files you use most regularly and save them in multiple physical locations. This is most useful when you accidentally delete a file you commonly use.
Online backup is very common and it works by sending copies of your data to a server through a third party network. The network will charge for the storage of data depending on the size, bandwidth and the number of users. It works by uploading data from software that is programmed to collect files from the client every hour, compress them, encrypt them and then send them to a secure server. The process can cater to small files as well as large ones and uploads can be done once a week or a few times a day; it really depends on the volume of data.
The costs can greatly differ between service providers as they use different systems, protection levels, and storage capacity to backup your files in case of an accident or outage. It makes perfect sense to backup data, considering the average company in the United States loses between $100,000 and $1 million because of data loss. A company’s down time because of data loss can cost well over $50,000 an hour. Similarly, an individual stands to lose a lot if he or she ever lost the data on their computer. So, in order to prevent the chance of that ever happening, you have to put in place a system that will ensure all your files are protected and kept safe at all times.
Create a backup of a backup of a backup. One of the major approaches people have to data backup is copying all of their files to an external hard drive - music, pictures, movies, financial documents and any other valuable files they have. The problem is, simply copying the data to an external memory device does not guarantee the safety of those documents. For starters, you should know that if you do not have a system that stores your data in more than two different locations, then you do not have a backup system at all. What you need is a foolproof plan where you know there is not a chance in the world that your documents are going to get lost. Copying the data is the first step, but you need to make sure it is secured. You can keep two or three separate backup drives and make sure they are stored in different locations, but you will still need the services of a good IT company that offers storage services in an offsite sever. It does not have to cost much, but this will be the perfect way to ensure your data never gets lost.
There are enough inexpensive companies, which provide cloud backup should you need the service, but just make sure you deal with a renowned company. Recovery is much easier when you have everything stored securely. Furthermore, You do not really have to create the plan; you could hire an IT company that does that kind of job. It is not as expensive as losing your files; more than 90% of businesses that suffer severe data loss actually shutdown in the first five years of operation.
Performing Data Recovery After Registry Corruption in Oliver Powell's Blog
Posted by Oliver Powell Jan 11, 2012A hierarchical database in Windows Operating System that stores configuration settings and options is termed as Windows Registry. Thus, the registry database mainly has configuration settings for applications, hardware devices, and users. However, at times the corruption or the damage in the Windows registry database occurs due to various reasons like improper system shutdown, virus infection, operating system malfunctioning, file system corruption, human errors, etc. The major issue that arises after Windows Registry corruption is unbootability of Windows-based system and so unavailability of valuable data. In such case, complete backup of your data works as a boon, but in the absence of proper backup or if the backup also fails to restore your data then reliable third-party data recovery software can do the needful.
Let us discuss it through a practical example. While trying to restart your Windows XP based computer, you may encounter one of the following error messages:
“Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM” OR
“Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SOFTWARE” OR
“Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\SOFTWARE or its log or alternate” OR
“System hive error”
Thus, after encountering any of the above mentioned error messages, your system becomes unbootable and in addition the data saved in it becomes inaccessible.
Resolution:
To fix the above error message, you may try the below mentioned steps:
- Try to restore the system state before Windows registry damage.
- Check all the firmware drives, BIOS (Basic Input/Output) settings, hardware, and disk.
- However, if the problem still persists and you still are unable to get access to your data then formatting of hard drive is recommended. Formatting deletes all the data from the hard drive thus, to restore your valuable data you can use an updated backup. However, in unavailability of backup, opting for third-party data recovery software is a wise decision.
There are a large number of data recovery software available online but it is recommended to use only one which has good experience in the field of data recovery and has simple recovery steps. One such software is Stellar Phoenix Windows Data Recovery. The efficient data recovery software safely recovers lost/deleted data and also the data which is lost due to formatting or corruption of hard drive. This software is compatible with Windows 7, Vista, Server 2003, XP, 2000, and NT (SP4). So, what are you waiting for get your Windows data recovery software now!!!
The Virtual CPU Dilemma - Overprovisioning vCPU to pCPU ratios in The SANMAN
Posted by Archie Hendryx Jan 11, 20122011 was a year where despite the economic constraints everything Big was seemingly good; Big Data, Big Clouds, Big VMs etc. Caught in the industry’s lust for this excess, 2011 was also the year I lost count of how many overprovisioned resources to ‘Big’ Production VMs I witnessed. More often than not this was a typical reaction from System Admins trying to alleviate their fears of potential performance problems to important VMs. It was the year where I began to hear justifications such as “yes we are overprovisioning our production VMs..but apart from the cost savings, overallocating our available underlying resources to a VM isn’t a bad thing, in fact it allows it to be scalable”. Despite this 2011 was also the year where I lost count of the amount of times I had to point out that sometimes overprovisioning a VM does lead to performance problems - specifically when dealing with Virtual CPUs.
VMware refers to CPU as pCPU and vCPU. pCPU or ‘physical’ CPU in its simplest terms refers to a physical CPU core i.e. a physical hardware execution context (HEC) if hyper-threading is unavailable or disabled. If hyperthreading has been enabled then a pCPU would consitute a logical CPU. This is because hyperthreading enables a single processor core to act like two processors i.e. logical processors. So for example, if an ESX 8-core server has hyper-threading enabled it would have 16 threads that appear as 16 logical processors and that would constitute 16 pCPUs.
As for a virtual CPU (vCPU) this refers to a virtual machine’s virtual processor and can be thought of in the same vein as the CPU in a traditional physical server. vCPUs run on pCPUs and by default, virtual machines are allocated one vCPU each. However, VMware have an add-on software module named Virtual SMP (symmetric multi-processing) that allows virtual machines to have access to more than one CPU and hence be allocated more than one vCPU. The great advantage of this is that virtualized multi-threaded applications can now be deployed on multi vCPU VMs to support their numerous processes. So instead of being constrained to a single vCPU, SMP enables an application to use multiple processors to execute multiple tasks concurrently, consequently increasing throughput. So with such a feature and all the excitement of being ‘Big’ it was easily assumed by many that taking advantage of such a feature by provisioning additional vCPUs could only ever be beneficial – but if only it was that simple.
The typical examples I faced entailed performance problems that were either being blamed on the Storage or the SAN and not CPU constraints especially as overall CPU utilization for the ESX server that hosted the VMs would be reported as low. Using Virtual Instruments’ VirtualWisdom I was able to quickly conclude that the problem was not at all related to the SAN or Storage but the hosts themselves. By being able to historically trend and correlate the vCenter, SAN and Storage metrics of the problematic VMs on a single dashboard it was apparent that the high number of vCPUs to each VM was the cause. This was indicated by a high reading of what is termed the 'CPU Ready' metric.
To elaborate, CPU Ready is a metric that measures the amount of time a VM is ready to run against the pCPU i.e. how long a vCPU has to wait for an available core when it has work to perform. So while it’s possible that CPU utilization may not be reported as high, if the CPU Ready metric is high then your performance problem is most likely related to CPU. In the instances that I saw, this was caused by customers assigning four vCPUs and in some cases eight to each Virtual Machine. So why was this happening?
Well firstly the hardware and its physical CPU resource is still shared. Coupled with this the ESX Server itself also requires CPU to process storage requests and network traffic etc. Then add the situation that sadly most organizations still suffer from the ‘silo syndrome’ and hence there still isn’t a clear dialogue between the System Admin and the Application owner. The consequence being that while multiple vCPUs are great for workloads that support parallelization but this is not the case for applications that don’t have built in multi-threaded structures. So while a VM with 4 vCPUs will require the ESX server to wait for 4 pCPUs to become available, on a particularly busy ESX server with other VMs this could take significantly longer than if the VM in question only had a single vCPU.
To explain this further let’s take an example of a four pCPU host that has four VMs, three with 1 vCPU and one with 4 vCPUs. At best only the three single vCPU VMs can be scheduled concurrently. In such an instance the 4 vCPU VM would have to wait for all four pCPUs to be idle. In this example the excess vCPUs actually impose scheduling constraints and consequently degrade the VM’s overall performance, typically indicated by low CPU utilization but a high CPU Ready figure. With the ESX server scheduling and prioritising workloads according to what it deems most efficient to run, the consequence is that smaller VMs will tend to run on the pCPUs more frequently than the larger overprovisioned ones. So in this instance overprovisioning was in fact proving to be detrimental to performance as opposed to beneficial. Now in more recent versions of vSphere the scheduling of different vCPUs and de-scheduling of idle vCPUs is not as contentious as it used to be. Despite this, the VMKernel still has to manage every vCPU, a complete waste if the VM’s application doesn’t use them!
To ensure your vCPU to pCPU ratio is at its optimal level and that you reap the benefits of this great feature there are some straightforward considerations to make. Firstly there needs to be dialogue between the silos to fully understand the application’s workload prior to VM resource allocation. In the case of applications where the workload may not be known, it’s key to not overprovision virtual CPUs but rather start with a single vCPU and scale out as and when is necessary. Having a monitoring platform that can historically trend the performance and workloads of such VMs is also highly beneficial in determining such factors. As mentioned earlier CPU Ready is a key metric to consider as well as CPU utilization. Correlating this with Memory and Network statistics, as well as SAN I/O and Disk I/O metrics enables you to proactively avoid any bottlenecks and correctly size your VMs and hence avoid overprovisioning. This can also be extended in considering how many VMs you allocate to an ESX Server and in ensuring that its physical CPU resources are sufficient to meet the needs of your VMs. As businesses’ key applications become virtualized it’s an imperative that whether they are old legacy single threaded workloads or new multi threaded workloads the correct vCPU to pCPU ratio is allocated. In this instance size isn’t always everything it’s what you do with your CPU that counts.

Windows Vista uses Boot Configuration Data (BCD) in place of Boot.ini file which is used in earlier versions of Windows. BCD basically contains configuration data which is responsible for successful booting of Windows Vista based computer. Thus, any corruption or damage in BCD can halt the boot process of your Windows Vista based computer. This situation not only makes your system non-bootable but it also leads to inaccessibility of data stored on the hard disk of your computer. This situation of data inaccessibility can easily be handled from the updated backup. But, in the unavailability of backup, third-party hard drive recovery software can do the needful.
Let us exemplify the above situation. Suppose, you start your Windows Vista based computer but instead of Welcome screen, you encounter the following error message:
“File: \Boot\BCD Status: 0xc0000034 Info: The Windows Boot Configuration Data file is missing required information” To rectify this issue we must first understand the causes behind it.
Causes:
We receive this error when either of the below mentioned conditions is true:
- The Boot or BCD file is missing or damaged on the active partition.
- The Boot Manager (Bootmgr) entry is missing from BCD store.
Resolution:
To resolve this problem, use the following methods in the same order as they are present below:
Method1: Repair BCD store through ‘Startup Repair’ option
Method2: Rebuild the BCD store by using the ‘Bootrec.exe’ tool
Method3: Manually rebuild the BCD store by using ‘Bcdedit.exe’ tool
Mostly, these steps rectify the issue and make all your data accessible but if they fail then reinstallation of Windows Vista remains the only way to solve the problem. Though, reinstallation of operating system deletes all the data stored on the hard disk but you can always recover that data from the valid backup. However, if you do not have the backup then using third-party hard drive recovery software can work as boon. One of the reliable and highly recommended data recovery software is Stellar Phoenix Windows Data Recovery.
This is one of the user-friendly hard drive data recovery tools which recover lost, deleted, or inaccessible data from Windows Operating System based hard disks or other secondary storage media. The software is compatible with Windows 7, Vista, Server2003, XP, 2000, and NT4 (SP6) and supports recovery of 185 different file types.
Our next VMworld case study interview focuses on how a major game developer in Europe has successfully leveraged the hybrid cloud model.
We’ll learn how SEGA Europe is standardizing its cloud infrastructure across its on-premises operations, as well as with a public cloud provider. The result is a managed and orchestrated hybrid environment to test and develop multimedia games, one that dynamically scales productively to the many performance requirements at hand.
This story comes as part of a special BriefingsDirect podcast series from the recent VMworld 2011 Conference in Copenhagen. The series explores the latest in cloud computing and virtualization infrastructure developments. [Disclosure: VMware is a sponsor of BriefingsDirect podcasts.]
Here to tell us more about how the hybrid approach to multiple, complementary cloud instances is meeting SEGA’s critical development requirements in a new way is Francis Hart, Systems Architect at SEGA Europe, in London. The case study interview is moderated by Dana Gardner, Principal Analyst at Interarbor Solutions.
Here are some excerpts:
Gardner: Clearly one of the requirements in game development is the need to ramp up a lot of servers to do the builds, but then they sit there essentially unproductive between the builds. How did you flatten that out or manage the requirements around the workload support?Listen to the podcast. Find it on iTunes/iPod. Read a full transcript or download a copy. Sponsor: VMware.
Hart: Typically, in the early stages of development, there is a fair amount of testing going on, and it tends to be quite small -- the number of staff involved in it and the number of build iterations.
Going on, when the game reaches to the end of its product life-cycle, we’re talking multiple game iterations a day and the game size has gotten very large at that point. The number of people involved in the testing to meet the deadlines and get the game shipped on date is into the hundreds and hundreds of staff.
Gardner: How has virtualization and moving your workloads into different locations evolved over the years?
Hart: We work on the idea of having a central platform for a lot of these systems. Using virtualization to do that allowed us to scale off at certain times. Historically, we always had an on-premise VMware platform to do this. Very recently, we’ve been looking at ways to use that resource within a cloud to cut down from some of Capex loading but also remain a little bit more agile with some of the larger titles, especially online games that are coming around.
Gardner: We’re all very familiar with the amazing video games that are being created nowadays. And SEGA of course is particularly well-known for the Sonic the Hedgehog franchise going back a number of years. What are some of the other critical requirements that you have from a systems architecture perspective when developing these games?
Hart: We have a lot of development studios across the world. We're working on multiple projects. We need to ensure that we supply them with a highly scalable and reliable solution in order to test, develop, and produce the game and the code in time. ... We’re probably looking at thousands of individual developers across the world.
... The first part was dealing with the end of the process, and that was the testing and the game release process. Now, we’re going to be working back from that. The next big area that we’re actively involved in is getting our developers to develop online games within the hybrid environment.
So they’re designing the game and the game’s back-end servers to be optimal within the VMware environment. And then, also pushing from staging to live is a very simple process using the Cloud Connector.
We're restructuring and redesigning the IT systems within SEGA to be more of a development operations team to provide a service to the developers and to the company.
Gardner: How did you start approaching that from your IT environment, to build the right infrastructure?
Targeting testing
Hart: One of the first areas we targeted very early on was the last process in those steps, the testing, arguably one of the most time-consuming processes within the development cycle. It happens pretty much all the way through as well to ensure that the game itself behaves as it should, it’s tested, and the customer gets the end-user experience they require.
The biggest technical goal that we had for this is being able to move large amounts of data, un-compiled code, from different testing offices around the world to the staff. Historically we had some major issues in securely moving that data around, and this is what we started looking into cloud solutions for this.
For very, very large game builds, and we're talking game builds above 10 gigabytes, it ended up being couriered within the country and then overnight file transfer outside of the country. So, very old school methods.
We needed both to secure that up to make sure we understood where the game builds were, and also to understand exactly which version each of the testing offices was using. So it’s gaining control, but also providing more security.
Gardner: So we’re seeing a lot more of the role-play games (RPG) types of games, games themselves in the cloud. That must influence what you're doing in terms of thinking about your future direction.
Hart: Absolutely. We’ve been looking at things like the hybrid cloud model with VMware as a development platform for our developers. That's really what we're working on now. We've got a number of games in the pipeline that have been developed on the hybrid cloud platform. It gives the developers a platform that is exactly the same and mirrored to what it would eventually be in the online space through ISPs like Colt, which should be hosting the virtual cloud platform.
Gaining cost benefits
And one of the benefits we're seeing in the VMware offering is that regardless of what data center in the world is the standard platform, it also allows us to leverage multiple ISPs, and hopefully gain some cost benefits from that.
Very early on we were in discussions with Colt and also VMware to understand what technology stack they were bringing into the cloud. We started doing a proof of concept with VMware and a professional services company, and together we were able to come over a proof of concept to distribute our game testing code, which previously was a very old-school distribution system. So anything better would improve the process.
There wasn't too much risk to the company. So we saw the opportunity to have a hybrid cloud set up to allow us to have an internal cloud system to distribute the codes to the majority of UK game testers and to leverage high bandwidth between all of our sites.
For the game testing studios around Europe and the world, we could use a hosted version of the same service which was up on the Colt Virtual Cloud Director (VCD) platform to supply this to trusted testing studios.
Gardner: When you approach this hybrid cloud model, what about managing that? What about having a view into what’s going on so that you know what aspects of the activity and requirements are being met and where?
Hart: The virtual cloud environment of vCloud Director has a web portal that allows you to manage a lot of this configuration in a central way. We’re also using VMware Cloud Connector, which is a product that allows you to move the apps between different cloud data centers. And doing this allows us to manage it at one location and simply clone the same system to another cloud data center.
In that regard, the configuration very much was in a single place for us in the way that we designed the proof of concept. It actually helped things, and the previous process wasn’t ideal anyway. So it was a dramatic improvement.
One of the immediate benefits was around the design process. It's very obvious that we were tightening up security within our build delivery to the testing studios. Nothing was with a courier on a bike anymore, but within a secured transaction between the two offices.
Risk greatly reduced
Also from a security perspective, we understood exactly what game assets and builds were in each location. So it really helped the product development teams to understand what was where and who was using what, and so from a risk point of view it’s greatly reduced.
In terms of stats and the amount of data throughput, it’s pretty large, and we’ve been moving terabytes pretty much weekly nowadays. Now we’re going completely live with the distribution network.
So it’s been a massive success. All of the UK testing studios are using the build delivery system day to day, and for the European ones we’ve got about half the testing studios on board that build delivery system now, and it’s transparent to them.
VMware was very good at allowing us to understand the technology and that's one of the benefits of working with a professional services reseller. In terms of gotchas, there weren't too many. There were a lot of good surprises that came up and allowed us to open the door to a lot of other VMware technologies.
Now, we're also looking at alternating a lot of processes within vCenter Orchestrator and other VMware products. They really gave us a good stepping stone into the VMware catalogue, rather than just vSphere, which we were using previously. That was very handy for us.
Gardner: I’d like to just pause here for a second. Your use of vSphere 4.1 must have been an important stepping stone to be able to have the dynamic ability to ramp up and down your environments, your support infrastructure, but also skills.
Hart: Absolutely. We already have a fair footprint in Amazon Web Services (AWS), and it was a massive skill jump that we needed to train members of the staff in order to use that environment. With the VMware environment, as you said, we already have a large amount of skill set using vSphere. We have a large team that supports our corporate infrastructure and we've actually got VMware in our co-located public environment as well. So it was very, very assuring that the skills were immediately transferable.
Gardner: Now that you've done this, any words of wisdom, 20/20 hindsight, that you might share with others who are considering moving more aggressively into private cloud, hybrid cloud, and ultimately perhaps the full PaaS value?
Hart: Just get some hands-on experience and play with the cloud stack from VMware. It’s inexpensive to have a go and just get to know the technology stack.

This BriefingsDirect podcast discussion centers on how worldwide enterprise applications leader SAP has designed and implemented a private cloud infrastructure models that supports an internal consulting and training program.
By standardizing on a VMware cloud platform, SAP has been able to slash provisioning times for multiple instances of its flagship application suite in the training setting, as well as set the stage for wider adoption of cloud models.
Here to tell us about the technical and productivity benefits of private clouds is Dr. Wolfgang Krips, Senior Vice President of Global Infrastructure at SAP in Walldorf, Germany. The interview is conducted by Dana Gardner, Principal Analyst at Interarbor Solutions. [Disclosure: VMware is a sponsor of Briefings Direct podcasts.]
Here are some excerpts:
Gardner: What is it about private cloud that made the most sense for SAP?Listen to the podcast. Find it on iTunes/iPod. Read a full transcript or download a copy. Sponsor: VMware.
Krips: Expanding a bit on the use case, there is a specific challenge here. In the training business, people book their courses, and we know only on Friday evening who is attending the course on Monday. So we have only a very short amount of time over the weekend to set up the systems. That was one of the big challenges that we had to solve.
The second challenge is that, at the same time, these systems become more and more mission critical. Customers are saying, "If the system isn't available during the course, I'm not willing to pay." Maybe the customer will rebook the course. Sometimes he doesn’t. That means that if the systems aren't available, we have an immediate revenue impact.
You can imagine that if we have to set up a couple of hundred, or potentially a couple of thousand, systems over the weekend, we need a high degree of automation to do that. In the past, we had homegrown scripts, and there was a lot of copying and stuff like that going on. We were looking into other technologies and opportunities to make life easier for us.
A couple of challenges were that the scripts and the automation that we had before were dependent on the specific hardware that we used, and we can't use the same hardware for each of the courses. We have different hardware platforms and we had to adopt all the scripts to various hardware platforms.
When we virtualized and used virtualization technology, we could make use of linked cloning technology, which allowed us to set up the systems much faster than the original copying that we did.
The second thing was that by introducing the virtualization layer, we became almost hardware independent, and that cut the effort in constructing or doing the specific automation significantly.
Gardner: What did you need to put in place, and how difficult was it?
The important piece
Krips: Luckily, we already had some experience. The big thing in setting up the cloud is not getting, say, vSphere in place and the basic virtualization technology. It's the administration and making it available in self-service or the automation of the provisioning. That is the important piece, as most would have guessed.
We had some experience with the Lifecycle Manager and the Lab Manager before. So we said at that time because we did this last year, we set up a Lab Manager installation and worked with that to realize this kind of private cloud.
In this specific cloud, typically we have between a couple of hundred and a couple of thousand VMs running. Overall, at SAP we're running more than 20,000 virtual machines (VMs). And, in fact, I have about 25 private cloud installations.
... As I mentioned, this cloud has to work. If this goes down, it’s not like some kind of irrelevant test system is down -- or test system pool -- and we can take up another one. Potentially a lot of training courses are not happening. With respect to mission criticality, this cloud was essential.
Gardner: We often hear similar requirements being applied to a test and development environment. Are some of your clouds involved with the test and development as well?
Krips: As I mentioned before, we have 25 private-cloud installations, and in fact, most of them are with development. We also have cloud installations in the demo area. So if sales people are providing demos, there are certain landscapes or resource pools where we are instantiating demo systems.
SAP wants to shorten the innovation cycles. Internally, we've moved internally to a development model, where every six weeks development provides potentially a shippable release. It doesn’t mean that the release gets shipped, but we’re running through the whole process of developing something, testing it, and validating it. There is a demonstrable release available every six weeks.
In the past, with a traditional model, if we were provisioning physical hardware, it took us about 30 days or so to provision a development system. Now, if you think about a development cycle of six weeks and you’re taking about nearly the same amount of time for provisioning the development system, you’ll see that there is a bit of a mismatch.
Moving to the private cloud and doing this in self-service, today we can provision development systems within hours.
Gardner: That’s what I hear from a number of organizations, and it's very impressive. When you had a choice of different suppliers, vendors, and professional services organizations, was there everything that led you specifically to VMware, and how has that worked out?
Krips: I can give you a fairly straightforward answer. At the time we started working with private cloud and private-cloud installations, VMware was the most advanced provider of that technology, and I'd argue that it is still today.
Gardner: How about security and management benefits?
Very reluctant
Krips: From our perspective, we wanted to have the advantages of cloud with respect to flexibility, provisioning speed, but we didn’t want to have more security headaches than we already had. That’s why we said, "Let's get our arms first around a private cloud."
Gardner: Is there something about a standardized approach to your cloud stack that makes that hybrid potential, when you’re ready to do it, when it's the right payload, something that you'll be pursuing?
Krips: That’s one of our biggest problems that we're having. Clearly, if one had a standard cloud interface like a vCloud interface, and it was the industry norm, that would be extremely helpful. The issue is that, as you can imagine, there are a couple of workloads that we also want to test in some other well known clouds. I'm having a bit of a headache over how to connect to multiple clouds.
... Now, if a couple of interesting providers had a standardized cloud interface, it would be very nice for me.
Gardner: Any thoughts about what your experience and benefits with cloud might mean for your future vision around client devices and mobility?
Krips: Dana, the thing is pretty clear. If you look at the strategy that SAP pursues, mobility is an integral part. We also think that not only that business process mobility is more important, but what we’re also seeing, and I mentioned that before, with the agility and development. So for instance, there are people who are working every couple of months in new teams. For us, it's very important that we separate the user data and the desktop from the device. We’re definitely pushing very strongly into the topic of desktop virtualization (VDI).
SaaS application
The big challenge that we’re currently having is that when you’re moving to VDI, you take everything that’s on the user's desktop today, then you make out of that more or less a software-as-a-service (SaaS) application. As you can imagine, if you’re doing that to development, and they are doing some complex development for the user interfaces or stuff like that, this puts certain challenges on the latency that you can have to the data center or the processing power that you need to have in the back-end.
From our side, we’re interested in technologies similar to that view, and where you can check out machines and still run on a VDI client, but leverage the administrative and provisioning advantages that you have through the cloud provisioning for virtual desktops. So it's a pretty interesting challenge.
We understand what kind of benefits we’re getting from the cloud operations, as I said, the center provisioning, application patching, improved license management, there are a lot of things that are very, very important to us and that we want to leverage.
Particularly for us, the VDI, the benefits, are very much in the kind of centralized provisioning. Just to give you an example, imagine how easy it would be if you’re doing desktop virtualization, to move from Windows 7 to Windows 8. You could basically flip a switch.
On the other hand, we have to solve the issue that we’re not blowing the business case, because the processing power and the storage that you have at the end point is relatively cheap. That’s why we were so interested in VDI technologies. That would allow us also to take care of all of our mobile users.
But we’re confident that we can get the business case to work.

Overview of VMware Vcloud Director 1.5 in Kuver Pratap Singh's Blog
Posted by Kuver Pratap Singh Dec 16, 2011Hi All,
This is my First blog about VMware vcloud Director...I hope it's usefull to you for better understanding about VMware vCloud Director...
National Institute of Standards and Technology (NIST), cloud computing is defined as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned
and released with minimal management effort or service provider interaction.
Cloud Computing is a revolution that will define IT beginning in the second decade of the 21st Century. This new form of computing is perfectly poised to provide solutions to a host of business problems within organizations large and small. Cloud Computing will be the catalyst for the long predicted notion of "ubiquitous computing." So just what "is" Cloud Computing, and why it is so different from what has come before? The following pages will detail four main areas in which Cloud Computing allows businesses to break from the past:
Virtualization – The ability to increase computing efficiency.
Democratization of Computing – Bringing enterprise scale infrastructure to small and mid-size businesses.
Scalability and Fast Provisioning – Bringing web scale IT at a rapid pace.
Commoditization of Infrastructure – Enabling IT to focus on the strategic aspects of its role.
This cloud model promotes availability and is composed of three service models and four deployment models.
1. Infrastructure as a Service (IaaS). In this environment, the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications.
2. Software as a Service (SaaS), in which the consumer is given access to software running in the provider’s environment.
3Platform as a Service (PaaS), in which the consumer can use the provider’s hardware to run applications created with the specific programming languages and tools supported by that provider.
Cloud environments may be separated into four categories based on the consumers they serve:
Private cloud—The cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on premise or off premise.
Community cloud—The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizatio or a third party and may exist on premise or off premise.
Public cloud—The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud—The cloud infrastructure is a composition of two or more clouds (private,community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
Many enterprises and IT service providers are developing cloud service offerings for public and private environments.
All above given information related to Cloud Computing it's essential for better understand to VMware vCloud Director 1.5...
VMware vCloud Director: The VMware vCloud solution is a suite of products designed to enable an IT organization to build a private cloud on top of a vSphere environment. The product suite consists of vCloud Director 1.5, VMware vShield Edge 5.0 and VMware vCenter chargeback1.6.2.
vCloud Director a single instance of vCloud Director is known as a “cell.” A cell consists of the vCloud Director components installed on a supported system. In larger implementations, multiple cells can be deployed with a front-end IP load balancer to direct end-user traffic to the correct cell.
vCloud Director stores information about managed objects, users and other metadata in a database. The current release of vCloud Director supports Oracle and Microsoft SQL Server for database platforms. In most environments, the vCloud Director and database components are installed on separate virtual machines for proper load handling.
vCenter Server :
Each vCloud Director cell can connect to one or more vCenter Server instances to access resources for running workloads. Each attached vCenter Server instance provides resources, such as CPU and memory, which can be leveraged by vCloud Director.You have to deploy vcloud VM over vCenter by Installabe Package or OVF Appliance , you can donwnlaod trial Package by www.vmware.com.
VMware ESXi hosts:
VMware ESXi hosts provide the compute power for vCloud Director. ESXi hosts are placed in groups of resources, such as clusters or resource pools. These groups and their associated storage are then made available to vCloud Director. Add Esxi Host in Cluster and make a Resource Pool, if you are seeing no option for enabling Resource Pool, edit the cluster setting and select DRS option enable.
VMware vShield Manager:
VMware vShield Manager provides a central point of control for managing, deploying, reporting, logging and integrating vShield as well as third-party security services. Working in conjunction with vCenter Server, VMware vShield Manager enables role-based access control and separation of duties as part of a unified framework for managing virtualization security.
vShield Edge secures the perimeter, or edge, around a virtual datacenter. vShield Edge secures the edge of a virtual datacenter with firewalling, VPN, NAT, DHCP, and Web load-balancing capabilities. vShield Edge allows cloud infrastructures to be scaled in a rapid and secure manner.

Exchange Completion Time – Redefining Application & Storage Performance in The SANMAN
Posted by Archie Hendryx Dec 3, 2011Roll back several years and certain vendors had you believe that Fibre Channel was dead and that the future would be iSCSI. A few years later and certain vendors were then declaring that Fibre Channel was dead again and that the future was FCoE. So while this blog is not a iSCSI vs FC or FC vs FCoE comparison list (there’s plenty of good ones out there and both iSCSI or FCoE each have immense merit), the point being made here is that Fibre Channel unlike Elvis really is alive and well. Moreover Fibre Channel still remains the protocol of choice for most Mission Critical Applications despite the FUD that surrounds its cost, manageability and future existence. Most Storage folk who run Enterprise class infrastructures are advocates of Fibre Channel not only because of its high performance connectivity infrastructure but also due to its reliability, security and scalability. Incredibly this is all with the majority of Fibre Channel implementations being vastly under utilized, poorly managed (due to lack of visibility) and running at a far from optimized state due to the constant day to day operations of most SAN Storage administrators. Indeed if Storage folk were empowered with a metric that could enable them to gain a better insight and understanding of their SAN Storage’s performance and utilization the so called impending death of Fibre Channel may have to take an even further rain check. Well that metric does exist; cue what is termed the “Exchange Completion Time.”
It’s now common for me to visit customer environments that run Fibre Channel SANs yet have various factions that complain they are suffering performance issues due to lack of bandwidth or throughput, whether that's server, VM, Network or Storage teams. In every single instance FC utilization has actually been incredibly low with peaks of 10% at the most and that's with 4GB/s environments not 8GB/s! At worst there may be an extremely busy backup server that singlehandedly causes bottlenecks and creates the impression that the whole infrastructure is saturated but even these occasions are often rare. What seems to be the cause of this misconception is the lack of clarity between what is deemed throughput and what is an actual cause of bottlenecks and performance slow downs i.e. I/O latency.
Sadly (and I am the first to admit that I was also once duped), Storage folk have been hoodwinked into accepting metrics that just aren’t sufficient to meet their requirements. Much like the folklore and fables of Santa Claus that are told to children during Christmas, storage administrators, architects and engineers have also been spun a yarn that MB/s and IOPS are somehow an accurate determination of performance and design considerations. In a world where application owners, server and VM admins are busily speaking the language of response times, Storage folk are engrossed in a foreign vocabulary that revolves around RAID levels, IOPS and MB/s and then numerous calculations to try and correlate the two languages together. But what if an application owner requested Storage with a 10ms response time that the Storage Administrator could then allocate with a guarantee of that performance? That would entail the Storage engineer not just looking at a one dimensional view from the back end of the Storage Array but one that incorporated the comprehensive transaction time i.e. from the Server to the Switch port to the LUN. That would mean considering the Exchange Completion Time.
To elaborate, using MB/s as a measurement of performance is almost akin to how people used to count cars as a measurement of road traffic. Harking back to my days as a student and before all of the high tech cameras and satellites that now monitor road traffic, I was ‘lucky’ enough to have a job of counting the amount of cars that went through Trafalgar Square at lunchtime. It was an easy job, I'd see five cars and I'd click five times but this was hardly accurate as when there was a traffic jam and all of the lanes were occupied I was still clicking five cars. Here also lies the problem with relying on MB/s as a measurement of performance. As with the counting car situation a more accurate way would have been to instead watch each single car and measure it's time from its origin to its destination. In the same vein, to truly measure performance in a SAN Storage infrastructure you need to measure how long a transaction takes from being initiated by the host, received by the storage and acknowledged back by the host in real-time as opposed to averages. This is what is termed the Exchange Completion Time.
While many storage arrays have tools that provide information on IOPS and MB/s to get a better picture of a SAN Storage environment and it’s underlying latency it's also key to consider the amount of Frames per second. In Fibre Channel a Frame is comparable to a word, a Sequence a sentence and an Exchange the conversation. A Standard FC Frame has a Data Payload of 2112 bytes i.e. a 2K payload. So for example an application that has an 8K I/O will require 4 FC Frames to carry that data portion. In this instance this would equate to 1 IOP being 4 Frames and subsequently 100 IOPS of the same size equating to 400 Frames. Hence to get a true picture of utilization looking at IOPS alone is not sufficient because there exists a magnitude of difference between particular applications and their I/O size with some ranging from 2K to even 256K. With backup applications the I/O sizes can be even larger. Hence it's a mistake to not take into consideration the amount of Frames/sec when trying to measure SAN performance or if trying to identify whether data is being passed efficiently. For example even if you are witnessing a high throughput in MB/s you may be missing the fact that there is a minimum payload of data and the Exchange (conversation) is failing to complete. This is often the case when there’s a slow draining device, flapping SFP etc. in the FC SAN network where instead of data frames causing the traffic you have a number of management frames dealing with issues such as logins and logouts, loss of sync or some other optic degradation or physical layer issue. Imagine the scenario, a Storage Administrator is measuring the performance of his infrastructure or troubleshooting a performance issue and is seeing lots of traffic via MB/s – unaware that many of the environment’s transactions are actually being cancelled across the Fabric!
This lack of visibility into transactions has also led to many storage architects being reluctant to aggressively use lower tiers of storage as poor I/O performance is often attributed to the storage arrays when often bottlenecks in the storage infrastructure are actually the root cause. Measuring performance via Exchange Completion Times enables measurement and monitoring of storage I/O performance, hence ensuring that applications can be correlated and assigned to their most cost- effective storage tier without sacrificing SLAs. With many Storage vendors adopting automated tiering within their arrays some would feel this challenge has now been met. The reality of automated tiering though is that LUNs or sub-LUNs are only dynamically relocated to different tiers based on the frequency of data access i.e. frequently accessed is more valuable so should reside on a higher tier and infrequently accessed data should be moved to lower tiers. So while using historical array performance and capacity data may seem a sufficient way to tier, it’s still too simplistic and lacks the insight for more optimized tiering decisions. Such an approach may have been sufficient to determine optimum data placement in the days of DAS when the I/O performance bottleneck was disk transfer rate but in the world of SANs and shared storage to look just at external transfer rates between SSD, Fibre Channel or SATA drives is a detached and inaccurate way to measure the effect of SAN performance on an application’s response time. For example congestion/problems in the SAN can result in severely degraded response times or cancelled transactions that fail to be acknowledged by the back end of the array. Furthermore incorrect HBA queue depths, the difference between sequential and random requests, link and physical layer errors all have an impact on response times and in turn application latency. By incorporating the Exchange Completion Time metric i.e. measuring I/O conversations across the SAN infrastructure into your tiering considerations, tiering can now accurately be based on comprehensive real time performance as opposed to device specific views.
Monitoring your FC SAN Storage environment in a comprehensive manner that incorporates the SAN fabric and provides metrics such as the Exchange Completion Time rapidly changes FC SAN troubleshooting from a reactive to proactive exercise. It also enables Server, Storage and Application administrators to have a common language of ‘response times’ thus eliminating any potential silos. With the knowledge of application I/O latency down to the millisecond, FC SAN Storage administrators can quickly be transformed from the initial point of blame to the initial point of resolution, while also ensuring optimum performance and availability of your mission critical data.
The latest BriefingsDirect podcast discussion centers on how new data and analysis approaches are significantly improving IT operations monitoring, as well as providing stronger security.
The conversation examines how AccelOps has developed technology that correlates events with relevant data across IT systems, so that operators can gain much better insights faster, and then learn as they go to better predict future problems before they emerge. That's because advances in big data analytics and complex events processing (CEP) can come together to provide deep and real-time, pattern-based insights into large-scale IT operations.
Here to explain how these new solutions can drive better IT monitoring and remediation response -- and keep those critical systems performing at their best -- is Mahesh Kumar, Vice President of Marketing at AccelOps. The discussion is moderated by Dana Gardner, Principal Analyst at Interarbor Solutions. [Disclosure: AccelOps is a sponsor of BriefingsDirect podcasts.]
Here are some excerpts:
Gardner: Is there a fundamental change in how we approach the data that’s coming from IT systems in order to get a better monitoring and analysis capability?Listen to the podcast. Find it on iTunes/iPod. Read a full transcript or download a copy. Sponsor: AccelOps. Connect with AccelOps: Linkedin, Twitter, Facebook, RSS.
Kumar: The data has to be analyzed in real-time. By real-time I mean in streaming mode before the data hits the disk.You need to be able to analyze it and make decisions. That's actually a very efficient way of analyzing information. Because you avoid a lot of data sync issues and duplicate data, you can react immediately in real time to remediate systems or provide very early warnings in terms of what is going wrong.
The challenges in doing this streaming-mode analysis are scale and speed. The traditional approaches with pure relational databases alone are not equipped to analyze data in this manner. You need new thinking and new approaches to tackle this analysis problem.
Gardner: Also for issues of security, offeners are trying different types of attacks. So this needs to be in real-time as well?
Kumar: You might be familiar with advanced persistent threats (APTs). These are attacks where the attacker tries their best to be invisible. These are not the brute-force attacks that we have witnessed in the past. Attackers may hijack an account or gain access to a server, and then over time, stealthily, be able to collect or capture the information that they are after.These kinds of threats cannot be effectively handled only by looking at data historically, because these are activities that are happening in real-time.
These kinds of threats cannot be effectively handled only by looking at data historically, because these are activities that are happening in real-time, and there are very, very weak signals that need to be interpreted, and there is a time element of what else is happening at that time. This too calls for streaming-mode analysis.
If you notice, for example, someone accessing a server, a database administrator accessing a server for which they have an admin account, it gives you a certain amount of feedback around that activity. But if on the other hand, you learn that a user is accessing a database server for which they don’t have the right level of privileges, it may be a red flag.
You need to be able to connect this red flag that you identify in one instance with the same user trying to do other activity in different kinds of systems. And you need to do that over long periods of time in order to defend yourself against APTs.
Gardner: It's always been difficult to gain accurate analysis of large-scale IT operations, but it seems that this is getting more difficult. Why?
Kumar: If you look at trends, there are on average about 10 virtual machines (VMs) to a physical server. Predictions are that this is going to increase to about 50 to 1, maybe higher, with advances in hardware and virtualization technologies. The increase in density of VMs is a complicating factor for capacity planning, capacity management, performance management, and security.
In a very short period of time, you have in effect seen a doubling of the size of the IT management problem. So there are a huge number of VMs to manage and that introduces complexity and a lot of data that is created.
Cloud computing
Cloud computing is another big trend. All analyst research and customer feedback suggests that we're moving to a hybrid model, where you have some workloads on a public cloud, some in a private cloud, and some running in a traditional data center. For this, monitoring has to work in a distributed environment, across multiple controlling parties.
Last but certainly not the least, in a hybrid environment, there is absolutely no clear perimeter that you need to defend from a security perspective. Security has to be pervasive.
Given these new realities, it's no longer possible to separate performance monitoring aspects from security monitoring aspects, because of the distributed nature of the problem. ... So change is happening much more quickly and rapidly than ever before. At the very least, you need monitoring and management that can keep pace with today’s rate of change.At the very least, you need monitoring and management that can keep pace with today’s rate of change.
The basic problem you need to address is one of analysis. Why is that? As we discussed earlier, the scale of systems is really high. The pace of change is very high. The sheer number of configurations that need to be managed is very large. So there's data explosion here.
Since you have a plethora of information coming at you, the challenge is no longer collection of that information. It's how you analyze that information in a holistic manner and provide consumable and actionable data to your business, so that you're able to actually then prevent problems in the future or respond to any issues in real-time or in near real-time.
You need to nail the real-time analytics problem and this has to be the centerpiece of any monitoring or management platform going forward.
Advances in IT
Gardner: So we have the modern data center, we have issues of complexity and virtualization, we have scale, we have data as a deluge, and we need to do something fast in real-time and consistently to learn and relearn and derive correlations.
It turns out that there are some advances in IT over the past several years that have been applied to solve other problems that can be brought to bear here. You've looked at what's being done with big data and in-memory architectures, and you've also looked at some of the great work that’s been done in services-oriented architecture (SOA) and CEP, and you've put these together in an interesting way.Big data is about volume, the velocity or the speed with which the data comes in and out, and the variety or the number of different data types and sources that are being indexed and managed.
Kumar: Clearly there is a big-data angle to this.
Doug Laney, a META and a Gartner analyst, probably put it best when he highlighted that big data is about volume, the velocity or the speed with which the data comes in and out, and the variety or the number of different data types and sources that are being indexed and managed.
For example, in an IT management paradigm, a single configuration setting can have a security implication, a performance implication, an availability implication, and even a capacity implication in some cases. Just a small change in data has multiple decision points that are affected by it. From our angle, all these different types of criteria affect the big data problem.
Couple of approaches
There are a couple of approaches. Some companies are doing some really interesting work around big-data analysis for IT operations.
They primarily focus on gathering the data, heavily indexing it, and making it available for search, thereby derive analytical results. It allows you to do forensic analysis that you were not easily able to with traditional monitoring systems.
The challenge with that approach is that it swings the pendulum all the way to the other end. Previously we had a very rigid, well-defined relational data-models or data structures, and the index and search approach is much more of a free form. So the pure index-and-search type of an approach is sort of the other end of the spectrum.
What you really need is something that incorporates the best of both worlds and puts that together, and I can explain to you how that can be accomplished with a more modern architecture. To start with, we can't do away with this whole concept of a model or a relationship diagram or entity relationship map. It's really critical for us to maintain that.What you really need is something that incorporates the best of both worlds and puts that together.
I’ll give you an example. When you say that a server is part of a network segment, and a server is connected to a switch in a particular way, it conveys certain meaning. And because of that meaning, you can now automatically apply policies, rules, patterns, and automatically exploit the meaning that you capture purely from that relationship. You can automate a lot of things just by knowing that.
If you stick to a pure index-and-search approach, you basically zero out a lot of this meaning and you lose information in the process. Then it's the operators who have to handcraft these queries to have to then reestablish this meaning that’s already out there. That can get very, very expensive pretty quickly.
Our approach to this big-data analytics problem is to take a hybrid approach. You need a flexible and extensible model that you start with as a foundation, that allows you to then apply meaning on top of that model to all the extended data that you capture and that can be kept in flat files and searched and indexed. You need that hybrid approach in order to get a handle on this problem.
Gardner: Why do you need to think about the architecture that supports this big data capability in order for it to actually work in practical terms?
Kumar: You start with a fully virtualized architecture, because it allows you not only to scale easily, ... but you're able to reach into these multiple disparate environments and capture and analyze and bring that information in. So virtualized architecture is absolutely essential.
Auto correlate
Maybe more important is the ability for you to auto-correlate and analyze data, and that analysis has to be distributed analysis. Because whenever you have a big data problem, especially in something like IT management, you're not really sure of the scale of data that you need to analyze and you can never plan for it.
Think of it as applying a MapReduce type of algorithm to IT management problems, so that you can do distributed analysis, and the analysis is highly granular or specific. In IT management problems, it's always about the specificity with which you analyze and detect a problem that makes all the difference between whether that product or the solution is useful for a customer or not.In IT management problems, it's always about the specificity with which you analyze and detect a problem that makes all the difference.
A major advantage of distributed analytics is that you're freed from the scale-versus-richness trade-off, from the limits on the type of events you can process. If I wanted to do more complex events and process more complex events, it's a lot easier to add compute capacity by just simply adding VMs and scaling horizontally. That’s a big aspect of automating deep forensic analysis into the data that you're receiving.
I want to add a little bit more about the richness of CEP. It's not just around capturing data and massaging it or looking at it from different angles and events. When we say CEP, we mean it is advanced to the point where it starts to capture how people would actually rationalize and analyze a problem.
The only way you can automate your monitoring systems end-to-end and get more of the human element out of it is when your CEP system is able to capture those nuances that people in the NOC and SOC would normally use to rationalize when they look at events. You not only look at a stream of events, you ask further questions and then determine the remedy.
No hard limits
To do this, you should have a rich data set to analyze, i.e. there shouldn’t be any hard limits placed on what data can participate in the analysis and you should have the flexibility to easily add new data sources or types of data. So it's very important for the architecture to be able to not only event on data that are is stored in in traditional models or well-defined relational models, but also event against data that’s typically serialized and indexed in flat file databases.
Gardner: What's the payoff if you do this properly?
Kumar: It is no surprise that our customers don’t come to us saying we have a big data problem, help us solve a big data problem, or we have a complex event problem.Customers say they are so interconnected that they want these managed on a common platform.
Their needs are really around managing security, performance and configurations. These are three interconnected metrics in a virtualized cloud environment. You can't separate one from the other. And customers say they are so interconnected that they want these managed on a common platform. So they're really coming at it from a business-level or outcome-focused perspective.
What AccelOps does under the covers, is apply techniques such as big-data analysis, complex driven processing, etc., to then solve those problems for the customer. That is the key payoff -- that customer’s key concerns that I just mentioned are addressed in a unified and scalable manner.
An important factor for customer productivity and adoption is the product user-interface. It is not of much use if a product leverages these advanced techniques but makes the user interface complicated -- you end up with the same result as before. So we’ve designed a UI that’s very easy to use, requires one or two clicks to get the information you need; a UI-driven ability to compose rich events and event patterns. Our customers find this very valuable, as they do not need super-specialized skills to work with our product.
Key metrics
What we've built is a platform that monitors data center performance, security, and configurations. The three key interconnected metrics in virtualized cloud environments. Most of our customers really want that combined and integrated platform. Some of them might choose to start with addressing security, but they soon bring in the performance management aspects into it also. And vice versa.
And we take a holistic cross-domain perspective -- we span server, storage, network, virtualization and applications. What we've really built is a common consistent platform that addresses these problems of performance, security, and configurations, in a holistic manner and that’s the main thing that our customers buy from us today.
Free trial download
Most of our customers start off with the free trial download. It’s a very simple process. Visit www.accelops.com/download and download a virtual appliance trial that you can install in your data center within your firewall very quickly and easily.
Getting started with the AccelOps product is pretty simple. You fire up the product and enter the credentials needed to access the devices to be monitored. We do most of it agentlessly, and so you just enter the credentials, the range that you want to discover and monitor, and that’s it. You get started that way and you hit Go.We do most of it agentlessly, and so you just enter the credentials, the range that you want to discover and monitor, and that’s it.
The product then uses this information to determine what’s in the environment. It automatically establishes relationships between them, automatically applies the rules and policies that come out of the box with the product, and some basic thresholds that are already in the product that you can actually start measuring the results. Within a few hours of getting started, you'll have measurable results and trends and graphs and charts to look at and gain benefits from it.
Gardner: It seems that as we move toward cloud and mobile that at some point or another organizations will hit the wall and look for this automation alternative.
Kumar: It’s about automation and distributed analytics and about getting very specific with the information that you have, so that you can make absolutely more predictable, 99.9 percent correct of decisions and do that in an automated manner. The only way you can do that is if you have a platform that’s rich enough and scalable and that allows you to then reach that ultimate goal of automating most of the management of these diverse and disparate environments.
That’s something that's sorely lacking in products today. As you said, it's all brute-force today. What we have built is a very elegant, easy-to-use way of managing your IT problems, whether it’s from a security standpoint, performance management standpoint, or configuration standpoint, in a single integrated platform. That's extremely appealing for our customers, both enterprise and cloud-service providers.
I also want to take this opportunity to encourage those of your listening or reading this podcast to come meet our team at the 2011 Gartner Data Center Conference, Dec. 5-9, at Booth 49 and learn more. AccelOps is a silver sponsor of the conference.

Advanced and pervasive virtualization and cloud computing trends are driving the need for a better, holistic approach to IT support and remediation. Keeping virtualized servers that support mission-critical applications and databases at top levels of performance 24 x 7 is a much different problem than for maintaining physical servers in traditional configurations.That's why HP has made the service and support of global virtualization market leader VMware implementations a top priority. And while the technology to support and fix these virtualized environments is essential, the people, skills and knowledge to manage these systems are perhaps the most decisive elements of ongoing performance success.

Most enterprises, service providers and governments have ramped-up their use of virtualization over the past several years, with many impressive results. Those paybacks can only continue, however, if the overall service and support of these complex and dynamic environments keeps pace.The problem of effectively troubleshooting issues across virtualized data centers consisting of many products from many suppliers is daunting. But there's an added element. The stakes have never been higher for keeping applications and business up and running. Indeed, a businesses' IT systems are increasingly the actual business itself. It's hard to separate them.

Our next VMworld case study interview focuses on how Germany’s largest travel agency has remade their PC landscape across 580 branch offices using virtual desktops. We’ll learn how Germany’s DER Deutsches Reisebüro redefined the desktop delivery vision and successfully implemented 2,300 Windows XP desktops as a service.
This story comes as part of a special BriefingsDirect podcast series from the recent VMworld 2011 Conference in Copenhagen. The series explores the latest in cloud computing and virtualization infrastructure developments. [Disclosure: VMware is a sponsor of BriefingsDirect podcasts.]
Here to tell us what this major VDI deployment did in terms of business, technical, and financial payoffs is Sascha Karbginski, Systems Engineer at DER Deutsches Reisebüro, based in Frankfurt. The discussion is moderated by Dana Gardner, Principal Analyst at Interarbor Solutions.
Here are some excerpts:
Gardner: Why were virtual desktops such an important direction for you? Why did it make sense for your organization?Listen to the podcast. Find it on iTunes/iPod. Read a full transcript or download a copy. Sponsor: VMware.
Karbginski: In our organization, we’re talking about 580 travel agencies all over the country, all over Germany, with 2,300 physical desktops, which were not in our control. We had life cycles out there of about 4 or 5 years. We had old PCs with no client backups.
The biggest reason is that recovery times at our workplace were 24 hours between hardware change and bringing back all the software configuration, etc. Desktop virtualization was a chance to get the desktops into our data center, to get the security, and to get the controls.
DER in Germany is the number one in travel agencies. As I said, we're talking about 580 branches. We’re operating as a leisure travel agency with our branches, Atlasreisen and DER, and also, in the business travel sector with FCm Travel Solutions.
IT-intensive business
Gardner: This is a very IT-intensive business now. Everything in travel is done though networked applications and cloud and software-as-a-service (SaaS) services. So a very intensive IT activity in each of these branches?
Karbginski: That’s right. Without the reservation systems, we can’t do any flight bookings or reservations or check hotel availability. So without IT, we can do nothing.
Gardner: And tell me about the problem you needed to solve. You had four generations of PCs. You couldn’t control them. It took a lot of time to recover if there was a failure, and there was a lot of different software that you had to support.
Karbginski: Yes. We had no domain integration no control and we had those crashes, for example. All the data would be gone. We had no backups out there. And we changed the desktops about every four or five years. For example, when the reservation system needed more memory, we had to buy the memory, service providers were going out there, and everything was done during business hours.
We now have nearly about 100 percent virtualization. ... So it's about 99 percent virtualization. ... So the data is under our control in the data center, and important company information is not left in an office out there. Security is a big thing.
Gardner: What were some of the things that you had to do in order to enable this to work properly?
Karbginski: There were some challenges during the rollout. The bandwidth was a big thing. Our service provider had to work very hard for us, because we needed more bandwidth out there. The path we had our offices was 1 or 2-Mbit links to the headquarters data center. With desktop virtualization, we need a little bit more, depending on the number of the workplaces and we needed better quality of the lines.
So bandwidth was one thing. We also had the network infrastructure. We found some 10-Mbit half-duplex switches. So we had to change it. And we also had some hardware problems. We had a special multi-card board for payment to read out passports or to read out credit card information. They were very old and connected with PS/2.
Fixed a lot of problems
So there were a lot of problems, and we fixed them all. We changed the switches. Our service provider for Internet VPN connection brought us more quality. And we changed the keyboards. We don’t need this old stuff anymore.
Gardner: How has this worked out in terms of productivity, energy savings, lowering costs, and even business benefits?
Karbginski: Saving was our big thing in planning this project. The desktops have been running out there now about one year, and we know that we have up to 80 percent energy saving, just from changing the hardware out there. We’re running the Wyse P20 Zero Client instead of physical PC hardware.
We needed more energy for the server side in the data center, but if you look at it, we have 60 up to 70 percent energy savings overall. I think it’s really great.
Gardner: That’s very good. So what else comes in terms of productivity?
Karbginski: In the past, the updates came during the business hours. Now, we can do all software updates at nights or at the weekends or if the office is closed. So helpdesk cost is reduced about 50 percent.
... We're using Dell servers with two sockets, quad-core, 144-gigabyte RAM. We're also using EMC Clariion SAN with 25 terabytes. Network infrastructure is Cisco, based on 10 GB Nexus data center switches. At the beginning the project, we had View 4.0 and we upgraded it last month to 4.6.
The people side
Gardner: What were some of the challenges in terms of working this through the people side of the process? We've talked about process, we've talked technology, but was there a learning curve or an education process for getting other people in your IT department as well as the users to adjust to this?
Karbginski: There were some unknown challenges or some new challenges we had during the rollout. For example, the network team. The most important thing was understanding of virtualization. It's an enterprise environment now, and if someone, for example, restarts the firewall in the data center, the desktops in our offices were disconnected.
It's really important to inform the other departments and also your own help desk.
... The first thing that the end users told us was that the selling platform from Amadeus, the reservation system, runs much faster now. This was the first thing most of the end users told us, and that’s a good thing.
The next is that the desktop follows the user. If the user works in one office now and next week in another office, he gets the same desktop. If the user is at the headquarters, he can use the same desktop, same outlook, and same configuration. So desktop follows the user now. This works really great.
Gardner: Looking to the future, are you going to be doing this following-the-user capability to more devices, perhaps mobile devices or at home PCs?
Karbginski: We plan to implement the security gateway with PCoIP support for home office users or mobile users who can access their same company desktop with all their data on it from nearly every computer in the world to bring the user more flexibility.
Gardner: If you were advising someone on what to learn from your experience as they now move toward desktop virtualization, any thoughts about what you would recommend for them?
Inform other departments
Karbginski: The most important thing is to get in touch with the other departments and inform them about the thing you're doing. Also, inform the user help desk directly at the beginning of the project. So take time to inform them what desktop virtualization means and which processes will change, because we know most of our colleagues had a wrong understanding of virtualization.
They think that with virtualization, everything will change and we'll need other support servers, and it's just a new thing and nobody needs it. If you inform them what you're doing that nothing will be changed for them, because all support processes are the same as before, they will accept it and understand the benefits for the company and for the user.

People want to be able to get on Southwest.com, make a reservation, log on to their Rapid Rewards or our Loyalty Program, and they want to be able to do it when they want to do it, when they need to do it, from wherever they are. And it’s just great to be able to provide that service.
We provide that to them at any point in time that they want in a reliable manner. And that's really what it gets right down to -- to make the functions and the solutions that we provide ubiquitous so people don’t really need to think about anything other than, "I need to do this and I can do it now."
At your fingertips
Gardner: I travel quite a bit and it seems to me that things have changed a lot in the last few years. One of the nice things is that information seems to be at your fingertips more than ever. I never seem to be out of the loop now as a traveler. I can find out changes probably as quickly as the folks at the gate.
So how has this transfer of information been possible? How have you been able to keep up with the demands and the expectations of the travelers?
Young: If we talk about information and the flow of information through applications and services, it really starts to segment the core technical aspects of that so the customer and our employees don’t really need to think about it. When they want to get the flight at the gates, the passenger is on a flight leg, etc., they can go ahead and get that at any moment in time.
... The same is true of how we provide IT as a service. What we want to be able to do is provide IT whenever they want it, whenever they need it, at the right cost point, and to meet their needs. We've got some of the best customers in the world and they like to do things for themselves. We want to allow them to do that for themselves and be able to provide our employees the same.
Gardner: How in IT have you been able to create common infrastructures, reduce redundancy, and then yet still ramp up to meet all your requirements?
Significant volume
Young: What we've been able to do and how we have been able to meet some of those challenges is through a number of different VMware products. One of the core products is VMware itself, if we talk about vSphere, vMotion, etc., to be able to provide that virtualization. You can get a 1-to-10 virtualization depending on which type of servers and blades you're using, which helps us on the infrastructure side of the house to maintain that and have the storage, physical, and electrical capacity in our data centers.
But it also allows us, as we're moving, consolidating, and expanding these different data centers, to be able to move that virtual machine (VM) seamlessly between points. Then, it doesn’t matter where it’s running.
That allows us the capacity. So if we have a fare sale and I need to add capacity on some of our services, it gives our us and our team that run the infrastructure the ability to bring up new services on new VMs seamlessly. It plugs right into how we're doing things, so that internal cloud allows us not to experience blips.
It's been a great add for us from a capacity management perspective and being able to get the right capacity, with the right applications, at the right time. It allows us to manage that in such a way that it’s transparent to our end-users so they don’t notice any of this is going on in the background, and the experience is not different.
... We started our virtualized environments about 18 months ago. We went from a very small amount of virtualization to what we coined our Server 2.0 strategy, which was really the combination of commodity-based hardware blades with VMware on that.
And that allowed us last year in the first and second quarter to grow from several hundred VMs to over several thousand, which is where we're at today in the production environment. If you talk about production, development, and test, production is just one of those environments.
It has allowed us to scale that very rapidly without having to add a thousand physical servers. And it has been a tremendous benefit for us in managing our power, space, and cooling in the data center, along with allowing our engineers who are doing the day-to-day work to have a single way to manage it, deploy, and move stuff around even more automatically. They don’t have to mess with that anymore, VMware just takes care of the different products that are part of the VMware Suite.
Gardner: And your confidence, has it risen to the level where you're looking at 70, 80, 90, even more percent of virtualization? How do you expect to end that journey?
Ready for the evolution
Young: I would love to be at 100 percent virtualized. That would be fantastic. I think unfortunately we still have some manufacturers and software vendors -- and we call them vendors, because typically we don’t say partners -- who decide they are not going to support their software running in the virtualized environment. That can create problems, especially when you need to keep some of those systems up 24 x 7, 365, with 99.95 percent availability.
We're hoping that changes, but the goal would be to move as much as we can, because if I take a look at virtualization, we are kind of our internal private cloud. What that’s really doing is getting us ready for the evolution that’s going to happen over the next, 5, 7, or 10 years, where you may have applications and data deployed out in a cloud, a virtual private cloud, public cloud if the security becomes good enough, where you've got to bring all that stuff together.
If you need to have huge amounts of capacity and two applications are not co-located that need to talk back and forth, you've got to be much more efficient on the calls and the communications and make that seamless for the customer.
This is giving us the platform to start learning more and start developing those solutions that don’t need to be collocated in a data center or in one or two data centers, but can really be pushed wherever it makes sense. That could be from wherever the most efficient data center is from a green technology perspective, use the least electricity and cooling power, to alternate energy, to what makes sense at the time of the year.
That is a huge add and a huge win for us in the IT community to be able to start utilizing some of that virtualization and even across physical locations.
Gardner: Is there a centralization feature to this that also is paying dividends?
Young: That’s a huge cornerstone of the suite of tools that we've been able to get through VMware is being able to deploy custom solutions and even some of the off-the-shelf solutions on a standard platform, standard operating systems, standard configurations, standard containers for the web, etc. It allows us to deploy that stuff within minutes, whereas it used to take engineers manually going to configure each thing separately. That’s been a huge savings.
The other thing is, once you get the configuration right and you have it automated, you don’t have to worry about people taking some human missteps. Those are going to happen, and you've got to go back and redo something. That elimination of error and the speed at which we can do that is helping. As you expand your server footprints and the number of VMs and servers you have without having to add to your staff, you can actually do more with the same number of or fewer staff.
Gardner: How you feel about desktop virtualization?
Young: What’s really driven us to take a look at it is that around our environment we can control security on virtual desktops, etc., very clearly, very quickly and deliver that in a great service.
New mobile devices
The other thing that’s leading to this is, not just what we talked about in security, is the plethora of brand new mobile devices -- iPhones, iPads, Android devices, Galaxy. HP has a new device. RIM has a new device. We need to be able to deliver our services in a more ubiquitous manner. The virtual desktop allows us to go ahead and deliver some of those where I don’t need to control the hardware. I just control the interface, which can protect our systems virtually, and it’s really pretty neat.
I was on one of my devices the other day and was able to go in via virtual desktop that was set up to be able to use some of the core systems without having all that stuff loaded on my machine, and that was via the Internet. So it worked out phenomenally well.
Now, there are some issues that you have to do depending on whether you're doing collocation and facility, but you can easily get through some of that with the right virtualization setup and networking.

Educators are using of desktop virtualization in innovative new ways to enable "bring your own device" (BYOD) benefits for faculty and students. This latest BriefingsDirect interview explores how one IT organization has made the leap to allowing young users to choose their own client devices to gain access to all the work or learning applications and data they need -- safely, securely, and with high performance.
The nice thing about BYOD is that you can essentially extend what do you do on-premises or on a local area network (LAN) -- like a school campus -- to anywhere; to your home; to your travels, 24×7.
The Avon Community School Corp. in Avon, Indiana has been experimenting with BYOD and desktop virtualization, and has recently embarked in a wider deployment for both this school year.
To get their story, Dana Gardner, Principal Analyst at Interarbor Solutions, interviewed Jason Brames, Assistant Director of Technology, and Jason Lantz, Network Services Team Leader, both at Avon Community School. [Disclosure: VMware is a sponsor of BriefingsDirect podcasts.]
Here are some excerpts:
Gardner: You've been successful with server virtualization, but what made it important for you now to extend virtualization to the desktop?Listen to the podcast. Find it on iTunes/iPod. Read a full transcript or download a copy. Sponsor: VMware.
Brames: One of the things that is important to our district we noticed when doing an assessment of our infrastructure: We have aging endpoints. We had a need to extend the refresh rate of our desktop computers from what was typical -- for a lot of school districts typical is about a 5-year refresh rate -- to getting anywhere from 7 to 10, maybe even 12 years, out of a desktop computer.
By going to a thin client model and connecting those machines to a virtual desktop, we're able to achieve high quality results for our end users, while still giving them computing power that they need and allowing us to have the cost savings by negating the need to purchase new equipment every five years.
By going with virtual environment, the problem that we were looking to solve was really just that -- how do we provide extended refresh rate for all of our devices?
Supporting 5,500 computers
We're located about 12 miles west of Indianapolis, Indiana, and we have 13 instructional buildings. We're a pre-K-to-12 institution and we have approximately 8,700 students, nearing 10,000 end-users in total. We’re currently supporting about 5,500 computers in our district.
... Currently have 400 View desktop licenses. We’re seeing utilization of that license pool of 20-25 percent right now, and the primary reason that we’re seeing that utilization is because we’re really just beginning that phase, with this being our first year for our virtual desktop roll out. We’re really in the second year, but the first year of more widespread use.
We’re training teachers on how to adequately and effectively use this technology in their classroom with kids It's been very highly received and is being adopted very well in our classrooms, because people are seeing that we were able to improve the computing experience for them.
Lantz: With that many devices, getting out there and installing software, even if it’s a push, locally, or what have you, there's a big management overhead there. By using VMware View and having that in our data center, where we can control that, the ability to have your golden image that you can then push out to a number of devices has made it a lot easier to transition to this type of model.
We’re finding that we can get applications out quicker with more quality control, as far as knowing exactly what’s going to happen inside of the virtual machine (VM) when you run that application. So that’s been a big help.
A lot of our applications are Web-based, Education City. It’s a lot of graphics and video. And we found that we're still able to run those in our View environment and not have issues.
Gardner: What are you running in terms of servers? What is your desktop virtualization platform, and what is it that allows you to move on this so far?
Lantz: On the server side, we're running VMware vSphere 4.1. On the desktop side, we're running View 4.6. Currently in our server production, as we call it, we have three servers. And we're adding a fourth shortly. On the View side of things, we currently have two servers and we’re getting two more in the next month or so. So we’ll have a total of four.
Access from anywhere
Gardner: Now one of the nice things about the desktop virtualization and this BYOD is it allows people to access these activities more freely anywhere. How do you manage to take what was once confined to the school network and allow the students and other folks in your community to do what they need to do, regardless of where they are, regardless of the device?
Brames: We’re a fairly affluent community. We have kids who were requesting to bring in their own devices. We felt as though encouraging that model in our district was something that would help students continue to use computers that were familiar to them and help us realize some cost savings long term.
So by connecting to virtual desktops in our environment, they get a familiar resource while they're within our walls in the school district, have access to all of their shared drives, network drives, network applications, all of the typical resources that are an expectation of sitting down in front of a school-owned piece of equipment. And they're seeing the availability of all of those things on their own device.
... A typical classroom for us contains four student computing stations, as well as, depending upon the building size, three to five labs available. We’re not focusing our desktop virtualization on those labs. We’re focusing on the classroom computing stations right now. Potentially, we'll also be in labs, as we go into the future.
Then, in addition to those student computing stations, we’re seeing those applications where our administrative team or principals and our district-level administrators are able to begin using virtual desktops to access while they’re outside of the district and growing familiar with that, so that whenever we enter into that phase where we’re allowing our students to access from outside of our network, we have that support structure in place.
... We’re also seeing an influx of more mobile-type devices such as tablets and even smartphones and things like that. The percentage of our users that are using tablets and smartphones right now for powerful computing or their primary devices is fairly low. However, we anticipate over time that the variety of devices we’ll have connecting to our network because of virtual desktops is going to increase.
Gardner: How is that hand-off happening? Are you able to provide a unified experience yet?
Lantz: That’s part of phase two of our approach that we’re implementing right now. We’ve gotten it out into the classrooms to get the students familiar with it, so that they understand how to use it. The next step in that process is to allow them to use this at home.
We currently have administrators that are using it in this fashion. They have tablets and are using the View client they connect in and get the same experience if they're in school or out of school.
So we’re to that point. Now that our administrators understand the benefits, now that our teachers have seen it in the classrooms, it’s a matter of getting it out there to the community.
One of the other ways that we’re making it available is that at our public library, we have a set of machines that students can access as well, because as you know, not every student has access to high-speed Internet, but they are able to go to library, check out these machines, and be able to get into the network that way. Those are some of the ways that we’re trying to bridge that gap.
Huge win-win
Technology Integration Group has resources that allow us to see what other school districts are doing and what are some of the things that they’ve run into. Then, they bring back here and we can discuss how we want to roll it out in our environment. They’ve been very good at giving us ideas of what has worked with other organizations and what hasn’t. That’s where they've come in. They’ve really helped us understand how we can best use this in our environment.
Gardner: I often hear from organizations, when they move to desktop virtualization, that there are some impacts on things like network or storage that they didn’t fully anticipate. How has that worked for you? How has this roll out movement towards increased desktop virtualization impacted you in terms of what you needed to do with your overall infrastructure?
Lantz: Luckily for us we’ve had a lot of growth in the last two to three years, which has allowed us to get some newer equipment. So our network infrastructure is very sound. We didn’t run into a lot of the issues that commonly you would with network bandwidth and things like that.
On the storage side, we did increase our storage. We went with an EqualLogic box for that, but with View, it doesn’t take up a ton of storage space with link clones and things like that. So having seen a huge impact there, now as we get further into this, storage requirements will get greater, but currently that hasn’t been a big issue for us.
Gardner: On the flip-side of that, a lot of organizations I talk to, who moved to desktop virtualization, gained some benefits on things like backup, disaster recovery, security, and control over data and assets, and even into compliance and regulatory issues. Has there been an upside that you could point to in terms of being a more centralized control of the desktop content and assets?
Difficult to monitor
Lantz: When you start talking about students bringing in their own devices, it's difficult to monitor what's on that personally owned device.
We found that by giving them a View desktop, we know what's in our environment and we know what that virtual machine has. That allows us to have more secure access for those students without compromising what's on that student’s machine, or what you may not know about what's on that student’s machine. That’s been a big benefit for us allowing students to bring in their own devices.
Gardner: Do we have any metrics of success either in business or, in this case, learning terms and/or IT cost savings? What has this done for you? I know it's a little early, but what's the early results?
Brames: You did mention that it is a little bit early, but we believe that as we begin using virtual desktops more so in our environment, one of the major cost savings that we’re going to see as a result is licensing cost for unique learning applications.
Typically in our district we would have purchased x number of licenses for each one of our instructional buildings because they needed to utilize that with students in the classroom. They may have a certain number of students that need access to this application, for example, but they're not all accessing it during the same time of the day or it's on a machine that’s on a fat client, a physical machine somewhere in the building, and it's difficult for students to have access to it.
By creating these pools of machines that have specialty software on them we’re able to significantly reduce the number of titles we need to license for certain learning applications or certain applications that improve efficiencies for teachers and for students.
So that’s one area in which we know we’re going to see significant return on our investment. We already talked about extending the endpoints, and with energy savings, I think we can prove some results there as well. Anything to add, Jason?
Lantz: One of the ones that’s hard to calculate is, as you mentioned, maintenance or management of this piece and technology, as we all know you’re doing more with less. This really gives you the ability to do that. How you measure that is sometimes difficult, but there are definitely cost savings there as well.
Gardner: I know budgets are really important in just about any school environment. Do you have any sense of the delta there between what it would be if you stuck to traditional cost structures, traditional licensing, fat client, to get to that one to one ratio, compared to what you’re going to be able to do over time with this virtualized approach?
Brames: Our Advanced Learning Center is the school building that has primarily senior students and advanced placement students. There are about 600 students that attend there.
Last year, 75 percent of those students were using school-owned equipment and 25 percent of them were bringing their own laptops to school. This year, what we have seen is that 43 percent of our students are beginning to bring their own devices to connect to our network and have access to network resources.
If that trend continues, which we think it will, we’ll be looking at certainly over 50 percent next year, hopefully approaching 60-65 percent of our students bringing their own devices. When you consider that that is approximately 400 devices that the school district did not need to invest in, that’s a significant saving for us.
Gardner: If you could do this over again, a little bit of 20/20 hindsight, what might you want to tell others in terms of being prepared?
Lantz: One thing that’s important is that when you explain this to users, the words "virtual desktop" can be a little confusing to teachers and your end-users. What I've done is taken the approach of it’s no different than having a regular machine and you can set it up to where it looks exactly the same.
No real difference
When you start talking with end users about virtual, it gets into, okay, "So it’s running back here, but what problems am I going to encounter?" and those sort of things. Trying to get that end user to realize that there really isn’t a difference between a virtual desktop and a real desktop has been important for us for getting them on board and making them understand that it’s not going to be a huge change for them.

Cloudy Concepts: The Meaning of IaaS, PaaS, SaaS, MaaS, CaaS & XaaS. in The SANMAN
Posted by Archie Hendryx Oct 30, 2011Generally I.T. folk, whether in Storage, Virtualization, Change Management or Project Management love the use of acronyms and synonyms to express key concepts amongst each other. What other industry would allow an individual to spurt a line such as “Have SOX seen the BCP and CAB approval for our VDC’s DR SAN and will this then be added to the CMDB by CoB today?” without immediately flinching or bringing in a logopaedics specialist for help. More often than not, I.T. folk have also used these synonyms and acronyms as smokescreens to prevent outsiders from realizing “well this I.T. stuff is actually quite easy to understand and quite straightforward”.
Hence no surprise that when the seemingly simple concept of Cloud Computing took off, so did the emergence of an abundance of acronyms and synonyms reaping a new breed of I.T. professionals who were the only ones that could correctly understand them i.e. ‘The Cloud Specialist’. Despite this, the beauty of the Cloud (or as most people are starting to realise the synonym for the Internet) is that it not only encompasses the I.T.industry and their business demands but also the average end user who’s only experience with I.T. is their iPhone and its App Store. So while EMC’s extensive airport advertising may have initially confused a lot of tourists into thinking that the ‘Journey to the Cloud’ was a slogan for an up and coming budget airline, the general public are certainly now becoming aware of ‘The Cloud’. End users are now bombarded with Clouds from Microsoft claiming that Windows 7 is your ‘Path to the Cloud’, Pizza Restaurants offering free access to ‘the Cloud’ and Apple iPhone owners having iCloud enforced upon them (no comment on the security issues of your email contacts and personal photos being uploaded to Apple’s database). So while the idea of Public, Private and Hybrid Clouds become more familiar and understood even amongst the masses, it’s with surprise that I often find people within the IT industry who are still unaware or unsure of Cloud Service acronyms such as IaaS, PaaS, SaaS, Maas, Caas or Xaas.
To understand why there are so many acronyms with the Cloud, it is important to appreciate that the Cloud has a number of services which each of these classify. The first of these, IaaS (Infrastructure as a Service) is when the consumer does not deal with the infrastructure, instead the responsibility of the equipment is outsourced to the Service Provider. The Service Provider not only owns the equipment but will also be responsible for its running and maintenance, where the consumer will be charged on a ‘pay as you use’ basis. IaaS is often offered as a horizontally integrated service that includes not only the server and storage but also the connectivity domains. For example while the consumer may deploy and run their own applications and operating systems, the Iaas provider would typically provide the replication, backup and archiving (Storage), the powerful computing requirements (Server) or the network load balancing and firewalls (Connectivity domains).
PaaS provides the capability for consumers to have applications deployed without the burden and cost of buying and managing the hardware and software. In other words these are either consumer created or acquired web applications or services that are entirely accessible from the Internet. Usually created with programming languages and tools supported by the service provider these web applications enable the consumer to have control over the deployed applications and in some circumstances the application-hosting environment but without the complexity of the infrastructure i.e. the servers, operating systems or storage. Offering a quick time to market and services that can be provisioned as an integrated solution over the web, PaaS facilitates immediate business requirements such as application design, development and testing at a fraction of the normal cost.
Software as a service (SaaS) is the ability for a consumer to use on demand software that is provided by the service provider via a thin client device e.g. a web browser over the Internet. With SaaS the consumer has not only no management or control of the infrastructure such as the storage, servers, network, or operating systems, but also no control over the application’s capabilities. Culled from what were originally referred to as (ASPs) Application Service Providers, SaaS is a quick and efficient delivery model for key business applications such as customer relationship management (CRM), enterprise resource planning (ERP), HR and payroll.
Monitoring as a Service (MaaS) is at present still an emerging piece of the Cloud jigsaw but an integral one for the future. In the same way that businesses realised that their infrastructure and key applications required monitoring tools that would ensure the proactive elimination of any downtime risks, Monitoring as a Service provides the option to offload a large majority of those costs by having it run as a service as opposed to a fully invested in house tool. So for example by logging on to a thin client or central web based dashboard which is hosted by the service provider, the consumer can monitor the status of their key applications regardless of location. Add the advantages of an easy set up and purchasing process and MaaS could be a key pay as you use model for the de-risking of applications that are initially being migrated to the Cloud.
Communication as a Service (CaaS), enables the consumer to utilize Enterprise level VoIP, VPNs, PBX and Unified Communications without the costly investment of purchasing, hosting and managing the infrastructure. With the service provider responsible for the management and running of these services also, the other advantage the consumer has is that they needn’t require their own trained personnel, bringing significant OPEX as well as CAPEX costs.
Finally XaaS or ‘anything as a service’ is the delivery of IT as a Service through hybrid Cloud computing and is a reference to either one or a combination of Software as a Service (SaaS), Infrastructureas a Service (IaaS), Platform as a Service (PaaS) Communications as a service (CaaS) or monitoring as a service (Maas). XaaS is quickly emerging as a term that is being readily recognized as services that were previously separated on either private or public Clouds are becoming transparent and integrated.
So as the term ‘The Cloud’ finally breaks into the minds of the masses and takes meaning, the next phase will be to take the numerous services that are offered by the Cloud, mature them and enable consumers to fully understand their benefits. From Enterprise to SMB to end users, Cloud Services will inevitably bring immense benefits and cost savings. All that is now required is for consumers to know what all those unnecessarily complicated acronyms mean!
VMworld Solutions Exchange Demo Theater Presentations in VMworld Blog
Posted by VMworld Team Oct 19, 2011Some nice Labs
LAB 4 - Failover
In this lab we tested fault tolerant on a VM with no down time, is setup in a cluster which is the boundary. If the cluster fails fault tolerant will also fail.
We tested also a failover on vCenter if the disaster hits the fan, vCenter Heartbeat can solve the problem. With heartbeat you build a vCenter and SQL cluster which is active/passive. Especially interesting is to user heartbeat when you use stretch clustering.
And lastly we test backup software from VMware which is simple and easy to use, perhaps not have all the function that the big backup software has but for smaller/mid company’s it good enough. Its use the snapshot function so you can user incremental and you can ship the data to NFS store like a Datadomain backup disk device unit.
LAB 5 - SRM
Interesting product, what is nice in the new version is that you can run all the tests, failover and failback which are great. You have the replication functionality or you use the storage replication software. Also get a clear view if the VM is protected or not again a disaster.
Another interesting topic is DA versus DR.
DA: Disaster avoidance for VMware is stretch clustering
DR: Disaster Recovery for VMware is SRM.
LAB 22 - VMware View
Great product, easy to user for the user and VMware has built a complete concept around this.
In this lab we had a look at the broke, composer, view manager and the security gateway.
The security gateway was a nice setup with no AD connection and striped down Windows server.
And you can now run View on most of the device out there.
Lab 9 - Performance troubleshooting
In this lab we look at some of the most commonly user troubleshooting scenarios and one of the cool thing was the storage DRS to spread the datastore load and the IOPS setting on the VM disks.
Guest post by Phil Curran
While VMworld 2011 Las Vegas is behind us, VMworld 2011 Copenhagen is fast approaching and the CommVault team is hard at work with final preparations for the show. The CommVault team will be in booth #100C and will be showing off the latest CommVault Simpana 9 software capabilities for protecting and managing data in growing VMware environments, including our SnapProtect integration for virtual servers.
One of the big hits for us at VMworld Las Vegas was the demo of one the newest capabilities in Simpana 9 SP3, which is the ability to perform mailbox and individual email restores from a snapshot of a virtualized Microsoft Exchange environment.
Email platforms like Exchange typically have specific long-term retention and recovery requirements. As more organizations look to virtualize Exchange, the ability to retain email for compliance and discovery remains extremely important. Methods are needed to ensure efficient retention of this virtualized data and enable this data for eDiscovery. But there is really no need to archive redundant data from virtual machines and operating systems for compliance. A more efficient method is to extract just the email data that's required. The duplicate data on VMDKs and operating systems often does not need to be retained.
So, the secret sauce in the CommVault approach is the combination of CommVault's SnapProtect capability for driving and managing hardware snapshots with our Virtual Server Agent (VSA), which leverages deep integration into the virtual environment (VMware vSphere 5 in this example). The VSA orchestrates the virtual platform (leveraging VADP) to perform initial backup operation including the quiescing of VMs and applications as well as log truncation for application consistency. SnapProtect will then drive the creation and management of array-based snapshots of VM datastores. Simpana can then manage secondary copies of these snapshots and, in this example perform information mining operations which can extract out specific Exchange mailboxes and email for long-term retention.
If you're attending VMworld 2011 Copenhagen and want to learn more about CommVault's backup and archiving solutions for Exchange, swing by the booth and check out our demo. Hope to see you there!

Our next VMware case study interview focuses on the City of Fairfield, California, and how the IT organization there has leveraged virtualization and cloud-delivered applications to provide new levels of service in an increasingly efficient manner.
We’ll see how Fairfield, a mid-sized city of 110,000 in Northern California, has taken the do-more-with-less adage to its fullest, beginning interestingly with core and mission-critical city services applications.
This story comes as part of a special BriefingsDirect podcast series from the VMworld 2011 Conference. The series explores the latest in cloud computing and virtualization infrastructure developments.
Here to share more detail on how virtualization is making the public sector more responsive at lower costs is Eudora Sindicic, Senior IT Analyst Over Operations in Fairfield. The discussion is moderated by Dana Gardner, Principal Analyst at Interarbor Solutions. [Disclosure: VMware is a sponsor of BriefingsDirect podcasts.]
Here are some excerpts:
Gardner: Why virtualize mission-critical applications, things like police and fire support, first?Listen to the podcast. Find it on iTunes/iPod. Read a full transcript or download a copy. Sponsor: VMware.
Sindicic: First of all, it’s always been challenging in disaster recovery and business continuity. Keeping those things in mind, our CAD/RMS systems for the police center and also our fire staffing system were high on the list for protecting. Those are Tier 1 applications that we want to be able to recover very quickly.
We thought the best way to do that was to virtualize them and set us up for future business continuity and true failover and disaster recovery.
So I put it to my CIO, and he okayed it. We went forward with VMware, because we saw they had the best, most robust, and mature applications to support us. Seeing that our back-end was SQL for those two systems, and seeing that we were just going to embark on a brand-new upgrading of our CAD/RMS system, this was a prime time to jump on the bandwagon and do it.
Also, with our back-end storage being NetApp, and NetApp having such an intimate relationship with VMware, we decided to go with VMware.
Gardner: So you were able to accomplish your virtualization and also gain that disaster recovery and business continuity benefit, but you pointed out the time was of the essence. How long did it take you?.
Sindicic: Back in early fiscal year 2010, I started doing all the research. I probably did a good nine months of research before even bringing this option to my CIO. Once I brought the option up, I worked with my vendors, VMware and NetApp, to obtain best pricing for the solution that I wanted.
I started implementation in October and completed the process in March. So it took some time. Then we went live with our CAD/RMS system on May 10, and it has been very robust and running beautifully ever since.
Gardner: Tell me about your IT operations.
Sindicic: I have our finance system, an Oracle-based system, which consists of an Oracle database server and Apache applications server, and another reporting server that runs on a different platform. Those will all be virtual OSs sitting in one of my two clusters.
For the police systems, I have a separate cluster just for police and fire. Then, in the regular day-to-day business, like finance and other applications that the city uses, I have a campus cluster to keep those things separated and to also relieve any downtime of maintenance. So everything doesn’t have to be affected if I'm moving virtual servers among systems and patching and doing updates.
Other applications
We’re also going to be virtualizing several other applications, such as a citizen complaint application called Coplogic. We're going to be putting that in as well into the PD cluster.
The version of VMware that we’re using is 4.1, we’re using ESXi server. On the PD cluster, I have two ESXi servers and on my campus, I have three. I'm using vSphere 4, and it’s been really wonderful having a good handle on that control.
Also, within my vSphere, vCenter server, I've installed a bunch of NetApp storage control solutions that allow me to have centralized control over one level snapshotting and replication. So I can control it all from there. Then vSphere gives me that beautiful centralized view of all my VMs and resources being consumed.
It’s been really wonderful to be able to have that level of view into my infrastructure, whereas when the things were distributed, I hadn’t had that view that I needed. I’d have to connect one by one to each one of my systems to get that level.
Also, there are some things that we’ve learned during this whole thing. I went from two VLANs to four VLANs. When looking at your traffic and the type of traffic that’s going to traverse the VLANs, you want segregate that out big time and you’ll see a huge increase in your performance.
The other thing is making sure that you have the correct type of drives in your storage. I knew that right off the bat that IOPS was going to be an issue and then, of course, connectivity. We’re using Brocade switches to connect to the backend fiber channel drives for the server VMs, and for lower-end storage, we’re using iSCSI.
Gardner: And how has the virtualization efforts within all of that worked out?
Sindicic: It’s been wonderful. We’ve had wonderful disaster recovery capabilities. We have snapshotting abilities. I'm snapshotting the primary database server and application server, which allows for snapshots up to three weeks in primary storage and six months on secondary storage, which is really nice, and it has served us well.
We already had a fire drill, where one report was accidentally deleted out of a database due to someone doing something -- and I'll leave it at that. Within 10 minutes, I was able to bring up the snapshot of the records management system of that database.
The user was able to go into the test database, retrieve his document, and then he was able to print it. I was able to export that document and then re-import it into the production system. So there was no downtime. It literally took 10 minutes, and everybody was happy.
... We are seeing cost benefits now. I don’t have all the metrics, but we’ve spun up six additional VMs. If you figure out the cost of the Dells, because we are a Dell shop, it would cost anywhere between $5,000 and $11,000 per server. On top of that, you're talking about the cost of the Microsoft Software Assurance for that operating system. That has saved a lot of money right there in some of the projects that we’re currently embarking on, and for the future.
We have several more systems that I know are going to be coming online and we're going to save in cost. We’re going to save in power. Power consumption, I'm projecting, will slowly go down over time as we add to our VM environment.
As it grows and it becomes more robust, and it will, I'm looking forward to a large cost savings over a 5- to 10-year period.
Better insight
Gardner: Was there anything that surprised you that you didn’t expect, when you moved from the physical to the virtualized environment?
Sindicic: I was pleasantly surprised with the depth of reporting that I could physically see, the graph, the actual metrics, as we were ongoing. As our CAD system came online into production, I could actually see utilization go up and to what level.
I was also pleasantly surprised to be able to see to see when the backups would occur, how it would affect the system and the users that were on it. Because of that, we were able to time them so that would be the least-used hours and what those hours were. I could actually tell in the system when it was the least used.
It was real time and it was just really wonderful to be able to easily do that, without having to manually create all the different tracking ends that you have to do within Microsoft Monitor or anything like that. I could do that completely independently of the OS.
Gardner: We're hearing a lot here at VMworld about desktop virtualization as well. I don’t know whether you’ve looked at that, but it seems like you've set yourself up for moving in that direction. Any thoughts about mobile or virtualized desktops as a future direction for you?
On the horizon
Sindicic: I see that most definitely on the horizon. Right now, the only thing that's hindering us is cost and storage. But as storage goes down, and as more robust technologies come out around storage, such as solid state, and as the price comes down on that, I foresee that something definitely coming into our environment.
Even here at the conference I'm taking a bunch of VDI and VMware View sessions, and I'm looking forward to hopefully starting a new project with virtualizing at the desktop level.
This will give us much more granular control over not only what’s on the user’s desktop, but patch management and malware and virus protection, instead of at the PC level doing it the host level, which would be wonderful. It would give us really great control and hopefully decreased cost. We’d be using a different product than probably what we’re using right now.
If you're actually using virus protection at the host level, you’re going to get a lot of bang for your buck and you won't have any impact on the PC-over-IP. That’s probably the way we we'll go, with PC-over-IP.
Right now, storage, VLANing all that has to happen, before we can even embark on something like that. So there's still a lot of research on my part going on, as well as finding a way to mitigate costs, maybe trade-in, something to gain something else. There are things that you can do to help make something like this happen.
... In city government, our IT infrastructure continues to grow as people are laid off and departments want to automate more and more processes, which is the right way to go. The IT staff remains the same, but the infrastructure, the data, and the support continues to grow. So I'm trying to implement infrastructure that grows smarter, so we don’t have to work harder, but work smarter, so that we can do a lot more with less.
VMware sure does allow that with centralized control in management, with being able to dynamically update virtual desktops, virtual servers, and the patch management and automation of that. You can take it to whatever level of automation you want or a little in between, so that you can do a little bit of check and balances with your own eyes, before the system goes off and does something itself.
Also, with the high availability and fault tolerance that VMware allows, it's been invaluable. If one of my systems goes down, my VMs automatically will be migrated over, which is a wonderful thing. We’re looking to implement as much virtualization as we can as budget will allow.
