Shared memory

Using Hitachi software products, the number of pairs, migration plans, and pool
capacities and virtual volumes depend on the amount of capacity of shared memory
installed on the controller.
The shared memory capacity allocated by shared memory function and the cache
memory capacity required for adding shard memory function vary depending on storage
system models.
