Shared memory requirements

Additional shared memory is required when Dynamic Provisioning is used in conjunction with Dynamic Tiering, active flash, capacity saving (deduplication and compression), or Thin Image pools. The amount of additional shared memory needed depends on the size of the Dynamic Provisioning Thin Image and Dynamic Tiering pools.

Shared memory is installed and removed by your service representative. For details about the installation and removal of shared memory, see the hardware reference guide for your storage system.

Caution Before shared memory is removed, all Dynamic Provisioning, Dynamic Tiering, and active flash pools must be deleted.

When Dynamic Provisioning, Dynamic Tiering, dedupe and compression, and Thin Image are used, the pool capacity and the V-VOL capacity that can be created are expanded according to the shared memory expansion status.

When using Dynamic Provisioning, Dynamic Tiering, and active flash, Thin Image, and deduplication and compression, the capacity of a pool or V-VOL that can be created is also expanded according to the shared memory expansion status.
