Chapter 5: Integrated Striping
In this case, the SAS2 BIOS Configuration Utility will load after the system has
completed its power-on self test.
You can configure any combination of up to two Integrated Striping (RAID 0) volumes
and mirrored volumes on each SAS2 controller, up to a maximum of 14 physical disk
drives for the two volumes. (This includes one or two hot spare disks for mirrored
arrays.)
The following guidelines apply when creating an Integrated Striping volume:
• All physical disks in an Integrated Striping volume must be either SATA (with
extended command set support) or SAS (with SMART support). You cannot
combine SAS and SATA disks in the same volume. However, you can create one
volume with SAS disks and a second volume with SATA disks on the same
controller.
• Disks must have 512-byte blocks and must not have removable media.
• Integrated Striping volumes must have at least two disks and no more than 10 disks.
Integrated Striping volumes do not support hot spare disks.
Follow the steps below to configure an Integrated Striping (IS) volume with the SAS2
BIOS Configuration Utility. The procedure assumes that the required controller(s) and
disks are already installed in the computer system.
Creating IS Volumes
1. On the A
DAPTER LIST screen of the SAS2 BIOS Configuration Utility, use the arrow
keys to select a SAS adapter and press E
NTER.
The ADAPTER PROPERTIES screen appears.
2. Select RAID PROPERTIES and press ENTER.
The CREATE ARRAY window appears.
3. Select CREATE RAID 0 VOLUME.
The CREATE NEW ARRAY window appears.
4. Move the cursor to the RAID DISK column and select a line that has a No entry in
this column, indicating that the disk is not already part of the volume being created.
To add the disk to the new array, change the No to Yes by pressing the space bar.
5. Move the cursor to another line and press the space bar to add another disk to the
array.
6. Continue adding disks in this way until you have added the number you want.
7. Press C to create the array.
A menu appears.
8. From the menu options, select S
AVE CHANGES then exit this menu.
A Processing message appears briefly, and then the SAS2 BIOS Configuration
Utility returns to the A
DAPTER PROPERTIES window. Initialization of the new array
continues in the background.
