5.3 Volume Set Function

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.

5.3.1 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 128 Volume Sets in a Raid Set can be created in the RAID subsystem.

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

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.

The Volume Set setup screen allows user to configure the Volume Name, Capacity,

RAID level, Initialization Mode, Stripe Size, Cache Mode, Tagged Command Queuing, Fibre

Channel/LUN Base/LUN, and Volume To Be Created.
