Starting with version 10.1, VMware Cloud Director supports data center groups backed by NSX Data Center for vSphere with both an active and a stand-by egress point for a single network fault domain.
The organization virtual data centers in a local group are backed by a single vCenter Server instance.
In a local data center group, you can set a pair of edge gateways - an active egress point and a stand-by egress point, to support high availability and disaster recovery scenarios within the same network fault domain.
