We already have a 3 node VSAN 6.2 Hybrid cluster at what we'll call 'Site A' that's been running well for about 6 months. I just assembled a 2-node VSAN 6.5 Hybrid cluster at 'Site B' that's leveraging the newly added direct-connect support using dual 10Gb NICs for vMotion and VSAN traffic between the 2 hosts. Each site has its own vCenter Server appliance. Sites are connected via site-to-site VPN tunnels.
I understand that I need to deploy a witness appliance and my plan is to do that on the VSAN cluster at 'Site A' - how do I go about doing this? I understand how to deploy the OVA, but how does the cluster at 'Site B' know about the witness - do I configure that in the Stretched Cluster portion of VSAN configuration on 'Site B'?
