High Availability (HA) is responsible for restarting virtual machines on other VMware vSphere hosts in the cluster without manual intervention when a host outage is detected.

Combined, the two features ensure that the Greenplum Database cluster keeps running in case of an ESXi host outage. See for more information.

On the VMware vSphere Client Home page, navigate to vCenter -> Select your Cluster -> Configure -> Services -> vSphere DRS.
