vCenter High Availability (vCenter HA) protects not only against host and hardware failures but also against vCenter Server application failures. Using automated failover from active to passive, vCenter HA supports high availability with minimal downtime.


  1. In the cluster TCI_RES_CLUSTER and TCI_EDGE_CLUSTER settings, enable vCenter HA.
  2. Configure vSphere HA. Select the HA parameters based on your environment and application needs and VMware best practices.
