Additional shared memory is required when Dynamic Provisioning is used in conjunction with capacity saving (deduplication and compression). The amount of additional shared memory needed depends on the size of the Dynamic Provisioning pools. For VSP One B24, however, the shared memory cannot be expanded.

When Dynamic Provisioning, adaptive data reduction, and dedupe and compression are used, the pool capacity and the V-VOL capacity that can be created are expanded according to the shared memory expansion status. In addition, the capacity of a pool or V-VOL that can be created is also expanded according to the shared memory expansion status.

For additional shared memory requirements, see Pool specifications and requirements for each storage system.
