Integrated RAID Solution User Guide

You can configure an Integrated Mirroring Enhanced volume with up to 10 mirrored

disks. The following figure shows the logical view and physical view of an Integrated

Mirroring Enhanced volume with three mirrored disks. The firmware writes each mirrored

stripe to a disk and mirrors it to an adjacent disk.

RAID 1E

is another term for this type of

mirrored configuration.

Figure 3. Integrated Mirroring Enhanced with Three Disks

You can configure an Integrated Mirroring + Striping volume with an even number of

disks, ranging from a minimum of four disks to a maximum of ten disks. The following

figure shows the logical view and physical view of an Integrated Mirroring + Striping

volume with four mirrored disks. The firmware writes each mirrored stripe to a disk and

mirrors it to an adjacent disk.

RAID 10

is another term for this type of configuration.

Figure 4. Integrated Mirroring + Striping with Four Disks

The Intel SAS-3 BIOS configuration utility (SAS-3 BIOS CU) enables you to create

mirrored volumes during initial setup and to reconfigure them in response to hardware

failures or changes in the environment.

Caution:

The SAS3 BIOS CU deletes all existing data from the disks drives when you select them to

use for a mirrored volume.
