V olum e Set Function

A Volume Set is seen by the host system as a single logical drive. It is organized in a
RAID level with two or more physical drives. 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 drive capacity available in a
Raid Set. Multiple Volume Sets can exist on a group of drives in a Raid Set. Additional
Volume Sets created in a specified Raid Set will reside on all the physical drives in the
Raid Set. Therefore, each Volume Set on the Raid Set will have its data spread evenly
across all drives in the Raid Set.

The volume set features are as follows:

•

Volume sets of different RAID levels may co-exist on the same raid set.

•

Up to 16 volume sets can be created in a raid set.

•

The maximum addressable size of a single volume set is 2 TB.

Create Volume Set

To create a volume set, follow the procedure below:

1.

Select Volume Set Function from the Main menu.

2.

Choose Create Volume Set from Volume Set Function menu.

3.

The Create Volume From Raid Set option appears. This screen displays the

available raid sets. Scroll to the required raid set and press Enter.
