How VMHA works
**If I understand when you enable HA in a cluster. HA elects a single host as a Master.
The Master monitors the state of other hosts and Virtual Machines and communicates with vCenter.
Q: The master uses heartbeat to detect other hosts failure or isolation, what does it use t detect VM failure?
**The Master can detect if another host is failed or isolated using Heartbeats.
isolation is determined if the Master is still able to receive heartbeat from the datastore to which the defunct Host is not heartbeating back to the Master
Q: I wanted to make sure that the Datastore really does heartbeat with the Master host.
Thank you
