Q uick V olum e/R aid Setup

Quick Volume/Raid Set-up is the fastest way to prepare a raid set and volume set. It can be
completed with just a few keystrokes. Although drives of different capacity may be used in
the raid set, the smallest capacity drive in the RAID set is used as the capacity of all disk
drives in the RAID set.

RAID Level:

The total number of physical drives in a specific RAID set determine the RAID levels that
can be implemented. Press Enter on Quick Volume/Raid Set-up from the main menu; all
possible RAID levels will be displayed, as shown below:

Select Capacity:

A single volume set is created that consumes all or a portion of the disk capacity available
in the RAID set. To define the capacity of the volume set, use the Available Capacity
screen. The default value for the volume set is displayed. Use the arrow keys to modify the
volume set capacity and press Enter to accept the value. If it only uses part of the raid set
capacity, you can use the Create Volume Set option to define additional volume sets.

Stripe size

This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 0+1, 5, or 6
logical drive. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB.
A larger stripe size provides better read performance, especially if your computer
processes mostly sequential reads. However, if your computer processes a lot of random
read requests, a small stripe size should be selected.
