vSphere HA clusters allow ESXi hosts to work together as a group and provide performance assurance and higher levels of availability for hosted virtual machines. Before we get into building vSphere HA clusters, let’s go over how vSphere HA works. vSphere HA provides high availability for virtual machines by pooling the virtual machines and the hosts they reside on into a cluster of ESXi hosts. Hosts in the cluster are actively monitored through a network and datastore heartbeating and if a failure occurs, the virtual machines on failed hosts are automatically restarted on alternate hosts.
Note the distinction between vSphere HA (High Availability) and vSphere FT (Fault Tolerance). vSphere FT allows for no service interruption, …
