VMware vCenter server on ESXi

Summary

There's no details about vCenter requirements regarding multiple vSphere clusters.

One would expect linked vCenter clusters should be supported as most people with WAN sites would have a separate vSphere cluster on each and OTS Deploy mentions no ability to provide multiple vCenter credentials, leading to a logical conclusion that vCenters in different sites should be linked.

But that should be explicitly addressed somewhere. This page talks about vCenter, MetroCluster SDS [1] talks about vCenter, and FAQs talks about vCenter and none of these places talks about multiple vSphere clusters.

Another place where this information is required is for multi-node HA clusters (2,4,6,8) - there's no information if these can be in different vSphere clusters on same local LAN (and whether that would be accomplished by linking the vCenters). Also, where would OTS Deploy be located in that case - would we suggest another (e.g. 3rd) vSphere cluster if half of OTS nodes are deployed on each of two other vSphere clusters.
