Installation and Configuration Manual
3.7 Volume Set Function
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.
3.7.1 Create Volume Set
The following are the Volume Set features:
1. Volume sets of different RAID levels may coexist on the same Raid Set.
2. Up to 16 Volume Sets in a Raid Set can be created by the RAID subsystem controller. But only
4 Volume Sets can be mapped in each host channel (total 8 Volume Sets can be mapped).
To create Volume Set from a Raid Set, expand the Volume Set Functions in the main menu and
click on the
Create Volume Set link. The Select The Raid Set To Create Volume On It
screen will show all existing Raid Sets. Tick on the Raid Set where you want to create the Volume
Set and then click on the Submit button.
Configure the Volume Set name, Capacity, RAID level, Stripe Size, Cache Mode, Initialization Mode (if
needed), SATA Data Xfer Mode, and Channel/Drive#.
