Active
– Runs the active vCenter Server Appliance instance
– Uses a public IP address for the management interface
– Uses the vCenter HA network for replication of data to the Passive node.
– Uses the vCenter HA network to communicate with the Witness node.
Passive
– Is initially a clone of the Active node
– Constantly receives updates from and synchronizes state with the Active node over the vCenter HA network
– Automatically takes over the role of the Active node if a failure occurs
Witness
– Is a lightweight clone of the Active node
– Provides a quorum to protect against a split-brain situations
