Explanation:
In vSphere 6.5, the vCenter High Availability feature was introduced.
vCenter High Availability (vCenter HA) protects the vCenter Server Appliance against host and hardware failures. The active-passive architecture of the solution can also help reduce downtime significantly when the vCenter Server Appliance is patched. vCent
er HA is only available for the vCenter Server Appliance. For more information about vCenter HA, see the vCenter High Availability section of the vSphere Availability Guide.
