Vmware high availability is a great feature of vmware. If you have shared storage like SAN / NAS  you can create high availability by using two ESXI servers , so when any physical server goes down or its network connectivity looses, VM High Availability auto takes over and migrates the virtual guest machines off that server to another server.

[Please note that In case of any ESXi host failure, the vm files never copied/moved, only the ownership of those virtual machines is transferred from the failed host to the new host. This way, the virtual machines can be up and running again in just few seconds or the time required to boot that specific guest VM(s)]

Requirements:

  • You must have VMware Infrastructure Suite (FREE or FOUNDATION version not supported).
  • At least 2 ESX host systems for high availability.
  • A shared NAS or SAN between the ESXi Servers where the virtual machines will be stored. In case of any ESXi host failure, the vm files never copied/moved, only the ownership of those virtual machines is transferred from the failed host to the new host.
  • Try using same hardware for both ESXI servers to avoid compatibilities issues.

sorry, 😦 Due-to time shortage, I will write it more about it later. for info , email.
