After you install Site Recovery Manager, it remains in evaluation mode until you install a Site Recovery Manager license key.

Site Recovery Manager Server instances use several network ports to communicate with each other, with client plug-ins, and with vCenter Server. If any of these ports are in use by other applications or are blocked on your network, you must reconfigure Site Recovery Manager to use different ports.

Each Site Recovery Manager server can support a certain number of virtual machines, protection groups, datastore groups, vSphere Replication management server instances per host, and vSphere Replication servers per vSphere Replication appliance.
