Dynamic Provisioning advantage example

To illustrate the merits of a Dynamic Provisioning environment, assume you have twelve LDEVs from 12 RAID 1 (2D+2D) array groups assigned to a DP pool. All 48 disks contribute their IOPS and throughput power to all DP volumes assigned to that pool. Instead, if more random read IOPS horsepower is desired for a pool, then it can be created with 32 LDEVs from 32 RAID 5 (3D+1P) array groups, thus providing 128 disks of IOPS power to that pool. Up to 1024 LDEVs can be assigned to a single pool, providing a considerable amount of I/O capability to a few DP volumes.
