Trying to draft our a DR solution for VMware, hope to get some clue here.

Environment Setup

Site 1

ESX server1 with vm1 and vm2 virtual machine running on LUN1 (EMC box1)

Site 2

ESX Server 2 with vm3 and vm4 virtual machine running on LUN2 (EMC box2)

Site1 LUN1 is replicated to Site2 using SRDF

Site2 LUN2 is replicated to Site1 using SRDF

Questions

1. Solution for VHA ESX1 to ESX2 if ESX1 failed ?

2. Solution for VMotion vm1 from ESX1 to ESX2 ?

3. Solution if Site1 failed, will Site2 overtake all vm and up automatically ?

Thanks.
