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:
  • If a Remote Copy partnership exists to a system that supports a lower number of basic volumes, the maximum number of volumes is reduced to the lower limit, or 8192 if that is greater. For example, if one system has a limit of 15864 volumes and the other has a limit of 8192 volumes, both systems will be limited to 8192 volumes.
  • For HyperSwap volumes per system see Replication Properties.

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.

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.
