A Storage Center volume is a logical unit of storage that servers can access over a network. You can allocate more logical space
to a volume than is physically available on the Storage Center.

Storage Type Specifies the disk folder, tier redundancy, and data page size of the storage used by the volume.
Storage Profile Controls the RAID type, storage tiers, and data progression behavior for pages used by the volume.
Snapshot Profile Describes when to take periodic snapshots (also known as point-in-time copies) for one or more
volumes and the time at which snapshots are deleted (expired).
