vCenter High Availability (vCenter HA) offers a robust solution to safeguard the vCenter Server Appliance from unforeseen host and hardware setbacks. Utilizing an active-passive structure, it minimizes downtime during vCenter Server Appliance updates. The setup involves a three-node cluster, comprising Active, Passive, and Witness nodes, communicating over a private vCenter HA network. This ensures continuous data replication from the Active to the Passive node. Depending on the configuration, vCenter HA can function with either an embedded or an external Platform Services Controller. In scenarios involving an external Platform Services Controller, an external load balancer is essential to ensure seamless functioning even if one Platform Services Controller goes offline.
