Notes:

I/O group connections per system using policy-based replication example: If I/O group 0 in system 1 is replicating to two I/O groups in system 2, this counts as two connections. If I/O group 1 in system 1 is also replicating to these same I/O groups, that counts as two additional connections, for a total of four connections.
A volume configured for high availability and disaster recovery counts as using 2x the replicated volume capacity.

Active cloud snapshots per volume	256	256	256	256	256	256	256	256	256	256	256

Notes:

Total volume group snapshot production capacity includes legacy FlashCopy, snapshots, clone volumes and change volumes, where supported. For SV3 total volume group snapshot production capacity also includes volume mirroring.
Total snapshot capacity includes snapshots only.
IBM recommends that the sum of volume copies and snapshots in a system should not exceed 50,000 when using standard pools. Data reduction pools are recommended for larger configurations.
