1.4 Array Definition
1.4.1 RAID Set
A RAID Set is a group of disks containing one or more volume sets. It has the following features in the RAID subsystem controller:
1.Up to sixteen RAID Sets are supported per RAID subsystem controller.
2.From one to sixteen drives can be included in an individual RAID Set.
3.It is impossible to have multiple RAID Sets on the same disks.
A Volume Set must be created either on an existing RAID set or on a group of available individual disks (disks that are not yet a part of an raid set). If there are
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 disk 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.
1.Volume Sets of different RAID levels may coexist on the same RAID Set.
2.The maximum addressable size of a single volume set is 2 TB.
3.Up to
In the illustration below, Volume 1 can be assigned a RAID 5 level of operation while Volume 0 might be assigned a RAID 0+1 level of operation.
