Note: On some platforms, software features or combinations of software features are limited by available hardware. If applicable these will be documented in a Software Feature limits page in the relevant Hardware Guide.
The tables in this page use a set of abbreviations for the various FlashSystem (FS) products, and SVC nodes. A full table of these abbreviations can be found at the end of this document.
To make the tables easier to read, you can use the product selector to filter which products are shown.

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.
  • Contact IBM to review the supported limits when planning to use vVol replication.
  • A volume configured for high availability and disaster recovery counts as using 2x the replicated volume capacity.

Notes:
  • Total FlashCopy bitmap allowance and volume capacity includes legacy FlashCopy, snapshots, clone volumes and thin-clone volumes, where supported.
  • 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.
