A storage pool is an aggregation of physical storage resources (disks) in a storage system. Storage systems contain information about the storage ports through which they can be accessed. You can provision logical storage spaces, known as volumes, from storage pools.
You can choose one or more storage pools when adding a storage system to the appliance. Storage pools are created on a storage system using the management software for that system. You cannot create or delete storage pools from the appliance—you can only add or remove them from management. After you add storage pools, you can provision volumes on them.
