BIOS CONFIGURATION

3.6 Using RAID Set/Volume Set Function

Method

In “Raid Set Function”, you can use the “Create Raid Set” function

to generate a new RAID set. In “Volume Set Function”, you can

use the “Create Volume Set” function to generate an associated

volume set and conguration parameters.

If the current controller has unused physical devices connected,

you can choose the “Create Hot Spare” option in the “Raid Set

Function” to dene a global hot spare. Select this method to con-

gure new RAID sets and volume sets. The “Raid Set/Volume Set

Function” conguration option allows you to associate volume sets

with partial and full RAID sets.

3 The capacity for the current volume set is entered after highlighting the

desired RAID level and pressing the Enter key.

The capacity for the current volume set is displayed. Use the UP and

DOWN arrow keys to set the capacity of the volume set and press the

Enter key to conrm. The available stripe sizes for the current volume

set are then displayed.

4 Use the UP and DOWN arrow keys to select the current volume set

stripe size and press the Enter key to conrm. This parameter species

the size of the stripes written to each disk in a RAID 0, 1, 10(1E), 5 or 6

volume set. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64

KB, 128 KB, 256 KB, 512 KB, or 1M. A larger stripe size provides better

read performance, especially when the computer preforms mostly se-

quential reads. However, if the computer preforms random read requests

more often, choose a smaller stripe size.

5 When you are nished dening the volume set, press the Yes key to

conrm the “Quick Volume And Raid Set Setup” function.

6 Foreground (Fast Completion) Press Enter key to dene fast initialization

or selected the Background (Instant Available) or No Init (To Rescue Vol-

ume). In the “Background Initialization”, the initialization proceeds as a

background task, the volume set is fully accessible for system reads and

writes. The operating system can instantly access to the newly created

arrays without requiring a reboot and waiting the initialization complete.

In “Foreground Initialization”, the initialization proceeds must be com-

pleted before the volume set ready for system accesses. In “No Init”,

there is no initialization on this volume.

7 Initialize the volume set you have just congured

8 If you need to add additional volume set, using main menu “Create Vol-

ume Set” function.
