6.6 Volume Set Functions
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.
The following summaries are the volume set features for the 6Gb/s
SATA RAID controller.
1. Volume sets of different RAID levels may coexist on the same
RAID set and up to 128 volume sets per controller.
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 lim-
ited to 2TB, because the controller is capable of 64-bit LBA mode.
However the operating system itself may not be capable of ad-
dressing more than 2TB.
