Presenter:

VMware

Have you ever been confused by the "host" and "guest" memory usage metrics in VMware Infrastructure 3? Have you ever wondered why "host" memory usage can be greater than "guest" memory usage? In this session, we will define the "host" and "guest" memory terms and answer some common questions related to them. Along the way, we will discuss a variety of memory management concepts, such as virtual memory, large page support, memory pressure, and memory reclamation techniques. This will give you the background to better understand how memory usage patterns and interactions on the ESX Server host can affect the "host" and "guest" memory usage values you see in VirtualCenter. Finally, we will provide you with some best practices around memory management to keep your data center running smoothly and efficiently.
