Each PS Series array is a member in the group and is assigned to a storage pool.
3 PS Series storage pools
Containers for storage resources (disk space, processing power, and network bandwidth).
4 PS Series single-member storage pool
A PS Series array represented as a member within a pool to which it is assigned.
5 PS Series multimember storage pool
Multiple PS Series arrays represented as individual members within a pool to which they are assigned.
6 Storage space
Space received from PS Series arrays to allocate data as needed through various structures (volumes,
snapshots, thin provisioning, replicas, containers, SMB/NFS, quotas, and local users/groups).
