Per Volume (LUN)
Remote replication can be setup for an individual volume or a volume set containing multiple volumes.

StorPool detects and sends only the deltas, referring to the data that has been changed since the last succesful remote application run. Deltas are discovered by examining the metadata in RAM, so the remote replication mechanism is a very lightweight operation to the primary StorPool cluster.
