You can deploy Site Recovery Manager Server so that both instances connect to vCenter Server instances that share a Platform Services Controller.

In this configuration, both vCenter Server instances connect to the same Platform Services Controller within a single site.

Important: When the vCenter Server instances on the protected and recovery sites share the same Platform Services Controller, the Platform Services Controller becomes a single point of failure. If the Platform Services Controller goes offline, neither of the protected and recovery sites can function, and recovery is impossible. This configuration is not appropriate for disaster recovery, and is not recommended.
