4.3.4.1 vSphere Replication Manager Appliance
The vSphere Replication Manager Appliance is the main component of vSphere replication management services and it registers with the vCenter Server as a solution.
Each Manager Appliance and, therefore, each vCenter Server can support up to 2,000 replications. This is achieved by leveraging 10 replication server instances.
Note Only one vSphere Replication Manager Appliance can be registered with a vCenter Server. They have a 1:1 relationship. Additional scale can be achieved by leveraging additional vSphere Replication Server Appliances—up to 10 per vSphere Replication Manager to give the scale of 2,000 replications.
