1.4.1 Raid Set

A Raid Set is a group of disk drives containing one or more logical volumes called
Volume Sets. It is not possible to have multiple Raid Sets on the same disk drives.

A Volume Set must be created either on an existing Raid Set or on a group of available
individual disk drives (disk drives that are not yet a part of a Raid Set). If there are
existing Raid Sets with available raw capacity, new Volume Set can be created. New
Volume Set can also be created on an existing Raid Set without free raw capacity by
expanding the Raid Set using available disk drive(s) which is/are not yet Raid Set
member. If disk drives of different capacity are grouped together in a Raid Set, then
the capacity of the smallest disk will become the effective capacity of all the disks in
the Raid Set.

1.4.2 Volume Set

A Volume Set is seen by the host system as a single logical device. It is organized in a
RAID level with one or more physical disks. RAID level refers to the level of data
performance and protection of a Volume Set. A Volume Set capacity can consume all
or a portion of the raw capacity available in a Raid Set. Multiple Volume Sets can
exist on a group of disks in a Raid Set. Additional Volume Sets created in a specified
Raid Set will reside on all the physical disks in the Raid Set. Thus each Volume Set on
the Raid Set will have its data spread evenly across all the disks in the Raid Set.
Volume Sets of different RAID levels may coexist on the same Raid Set.

In the illustration below, Volume 1 can be assigned a RAID 5 level while Volume 0 might
be assigned a RAID 10 level.
