You can remove hosts from your SDDC as long as the number of hosts in your SDDC cluster remains above the minimum.

The minimum number of hosts for a single availability zone cluster is 4. The minimum number for a multiple availability zone cluster is 6.

When you remove a host, VMs running on that host are evacuated to other hosts in the SDDC cluster. The host is placed into maintenance mode and then removed.

Prerequisites

Ensure that you have sufficient capacity in your cluster to hold the workload VMs that will be evacuated from the hosts that you remove.
