You can use vSphere Replication with Site Recovery Manager in a shared recovery site configuration in the same way that you do in a standard one-to-one configuration.
You deploy one vSphere Replication appliance on each protected site. You deploy only one vSphere Replication appliance on the shared recovery site. All of the vSphere Replication appliances on the protected sites connect to this single vSphere Replication appliance on the recovery site. You deploy the vSphere Replication appliances in the same way as for a standard one-to-one configuration.
You can deploy multiple additional vSphere Replication servers on the shared recovery site to distribute the replication load. For example, you can deploy on the shared recovery site a vSphere Replication server for each of the protected sites that connects to the shared recovery site. For information about protection and recovery limits when using vSphere Replication with Site Recovery Manager in a shared recovery site configuration, see Operational Limits of Site Recovery Manager.
Prerequisites
- To use Site Recovery Manager with vSphere Replication, deploy the appropriate version of vSphere Replication on both of the protected and recovery sites before you install Site Recovery Manager Server. For information about compatibility between vSphere Replication and Site Recovery Manager versions, see vSphere Replication Requirements in the Compatibility Matrices for Site Recovery Manager 8.6 at https://docs.vmware.com/en/Site-Recovery-Manager/8.6/rn/srm-compat-matrix-8-6.html.
- If you have existing vSphere Replication appliances on the sites, you must either upgrade them to the correct version or unregister them from both vCenter Server instances before you install Site Recovery Manager.
