1- If I understand HA availability is helpful only when ESX servers are up, and one or some of them have their resources degrading in regards to the criteria set up in the cluster HA configuration.
I mean if one of ESX resources go below the threshold, VMs get migrated to another host.
What if both ESX servers(if we only had 2) go below the threshold ?
2- In the case one ESX server unexpectedly looses power, I believe HA will not come in handy in this case. Correct ?
3-I also would like if automatic Vmotion can only be done within the Cluster?
4-in which case the VMs get restarted in another ESX server?
