Explanation
A vCenter Server HA (VCHA) cluster consists of three nodes: Active, Passive, and Witness. Two services run on all three nodes: (A) vmware-vmon (VMware Service Lifecycle Manager) is the master process responsible for starting, stopping, and monitoring other vCenter services - it must be present on every node to manage service state; and (D) vmware-vcha is the VCHA coordination service itself, which handles heartbeating, failover detection, and cluster communication, so it must run on all three nodes. In contrast, (B) vmware-vpostgres (the embedded PostgreSQL database) only actively runs on the Active and Passive nodes (where the DB is replicated), not the Witness. The Witness node solely participates in quorum and failover decisions.
