vCenter HA network latency between Active, Passive, and Witness nodes must be less than 10 ms. The vCenter HA network must be on a different subnet than the management network. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.avail.doc/GUID-8FD87389-8CC9-4298-8B08-A1526FB44524.html

vCenter HA was introduced with the vCenter Server Appliance 6.5 The vCenter deployment size should be at least small, and therefore 4 vCPU 16 GB RAM A minimum of three hosts The hosts should be running at least ESXi 5.5 The management network should be configured with a static IP address and reachable FQDN SSH should be enabled on the VCSA A port group for the HA network is required on each ESXi host The HA network must be on a different subnet to the management network Network latency between the nodes must be less than 10ms vCenter HA is compatible with both embedded deployment model and external PSC
