Vcenter HA

When you have Vcenter HA does that also mean you can install updates on vCenter without any interuptions to vCenter? Will vCenter stay available because you can switch between the 2 nodes?

  1. When patching with vCenter HA, there is downtime for vCenter Server. The patching process, as you’d expect, requires you to failover between the nodes. This failover (and the optional failback) typically takes 5-10 depending on size and “busyness”. Many people just destroy the cluster, patch, then re-enable VCHA as a simpler method. But there may be more downtime involved there as vCenter Server is down while it is being patched instead of running on a secondary node.
