vRealize Operations Manager supports high availability (HA) by creating an additional node that is a replica of the vRealize Operations Manager master node. This node type is called a master replica.

When present, a master replica can take over the functions of a master node. When a problem occurs with the master node, failover to the replica node is automatic and requires only two to three minutes of vRealize Operations Manager downtime. Data stored on the master node is fully backed up on the replica node. With HA enabled, the cluster can survive the loss of a single data node without losing any data.
