PowerMaxOS and HYPERMAX OS offload data into a Storage Resource Pool. One or more Storage Resource Pools are pre-configured before installation and used by a variety of functions. DSE can use a Storage Resource Pool pre-configured specifically for DSE. If no such pool exists, DSE can use the default Storage Resource Pool. All SRDF groups on the array use the same Storage Resource Pool for DSE. DSE requests allocations from the Storage Resource Pool only when DSE is activated.
The Storage Resource Pool used by DSE is sized based on your SRDF/A cache requirements. DSE is automatically enabled.
