5.5.3 Volume Set Function
A volume set is seen by the host system as a single logical device; it is
organized in a RAID level within the controller utilizing one or more physical
disks. RAID level refers to the level of data performance and protection of a
volume set. A volume set can consume all of the capacity or a portion of the
available disk capacity of a RAID set. Multiple volume sets can exist on a RAID
set. If multiple volume sets reside on a specified RAID set, all volume sets will
reside on all 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 rather
than one volume set using some of the available disks and another volume set
using other disks.
The following is the volume set features for the RAID subsystem.
1. Volume sets of different RAID levels may coexist on the same RAID set.
2. Up to 128 volume sets can be created in a RAID set.
3. The maximum addressable size of a single volume set is not limited to 2TB,
because the controller is capable of 64-bit LBA mode. However the operating
system itself may not be capable of addressing more than 2TB.
