Question regarding volumes and snapshots when setting up replication with PowerFlex RCG.

Hello, I have questions about the behavior when setting up replication using RCG in PowerFlex.

1. when I add a volume pair to RCG, do the original and replica volumes have the same name?

2. How are the volumeClasses of the original and replicated volumes set?

3. if the source and replicated volumes have the same volumeId, why do I need to enter the same id value when adding a ReplicationPair, when according to the API documentation, there is a sourceVolumeId and a destinationVolumeId? (link)

4. The documentation says that the number of volumes maintained within an RCG is limited to 1024. If a snapshot of a volume bound to an RCG is added, I am wondering if (1) the snapshot is included in that RCG and therefore affected by the limit, (2) the snapshot is not replicated, or (3) if the snapshot is replicated, is it not affected by the limit?

I would appreciate if you could answer my long question.

Thank you.
