Integrated Striping configuration
The following must be considered when configuring the onboard SCSI RAID solution for
Integrated Striping:
■ The BIOS-based CU allows you to create one Integrated Striped volume per controller.
■ An IS volume can have from two to six disks.
■ Disks in an IS volume must be non-removable, single-LUN disks that support 512-byte
sectors, wide synchronous transfers, Qtag’d I/Os, and a unit serial number. The disks
must support SMART, and they must be minimally compliant with the SCSI-2
standard.
■ Disks in an IS volume must be connected to the same channel of the same controller,
and the controller must be in the BIOS boot order.
■ Disks of different size are allowed in IS volumes, but the smallest disk determines the
“logical” size of each disk in the volume. The excess space of larger member disks is
not used.
■ Usable disk space for each IS member disk is adjusted down to leave room for Meta
data. Usable disk space may be further reduced to maximize the ability to interchange
disks in the same size classification.
■ The supported stripe size is 64 Kbytes.
To configure the onboard SCSI RAID solution for Integrated Striping:
1
Open the BIOS Setup utility as described in the previous procedure.
2
On the Main menu screen, use the arrow keys to select an adapter, then press E
NTER
.
The Adapter Properties screen opens.
3
Use the arrow keys to select
RAID Properties
, then press E
NTER
.
The RAID Properties
screen opens.
4
Use the arrow keys to select the first disk for the IS volume, use the arrow keys to
move to the Array Disk column for this disk, then use the
+ and - keys to select
Yes
as the value for this column.
If partitions are defined on the selected disk, a message appears warning you that data
on the disk will be lost when the striped volume is created. You can then deselect
that disk or erase the disk and continue.
5
Repeat the previous step to select as many as five more disks for the striped volume.
If partitions are defined on the selected disks, a message appears warning you that
data on the disk will be lost when the striped volume is created. You can then deselect
that disk or erase the disk and continue.
