As I understand it - the appliance can support mulitple vCenters - the recommendation however if your vCenter are different geos is to deploy a Skyline Collector at each location. So that's one Cloud Org - 2 collectors and 2 vCenter - the main reason is for the log assist feature - the log collects and pushes can get sizable, and it doesn't add up to push that traffic across the WAN from one site to another, and up to VMware
