1.4 Array Definition
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 example, Volume 1 can be assigned a RAID 5 RAID level while Volume 0 might be assigned a
RAID 10 RAID level.
