Really just a lab environment for now, but hoping to deploy something one I get the hang of it.
The sites have site to site VPNs between them but the links are slow and somewhat unreliable.
Should I connect the ESXi hosts to a single vCenter instance at the main location or should I put a vCenter at each location on an ESXi host?
I believe you can have individual vCenter at each site due to the concern with latency issue.
If you are going for once 6.0 its better to have 1psc +1vCenter at remote location.
