RAID configurations
The motherboard comes with the Intel
you to configure IDE and Serial ATA hard disk drives as RAID sets.

SATA supportant les configurations RAID 0, RAID 1, RAID 10 et RAID 5 pour
six canaux Serial ATA indépendants.

RAID definitions
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data
in parallel, interleaved stacks. Two hard disks perform the same work as a single
drive but at a sustained data transfer rate, double that of a single disk alone, thus
improving data access and storage. Use of two new identical hard disk drives is
required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of data from one
drive to a second drive. If one drive fails, the disk array management software directs
all applications to the surviving drive as it contains a complete copy of the data in
the other drive. This RAID configuration provides data protection and increases fault
tolerance to the entire system. Use two new drives or use an existing drive and a
new drive for this setup. The new drive must be of the same size or larger than the
existing drive.
RAID 5 stripes both data and parity information across three or more hard
disk drives. Among the advantages of RAID 5 configuration include better
HDD performance, fault tolerance, and higher storage capacity. The RAID
5 configuration is best suited for transaction processing, relational database
applications, enterprise resource planning, and other business systems. Use a
minimum of three identical hard disk drives for this setup.
RAID 10 is data striping and data mirroring combined without parity (redundancy data)
having to be calculated and written. With the RAID 10 configuration you get all the
benefits of both RAID 0 and RAID 1 configurations. Use four new hard disk drives or
use an existing drive and three new drives for this setup.
Si vous souhaitez booter le système depuis un disque dur qui est inclus dans un
ensemble RAID, copiez au préalable le pilote RAID depuis le CD de support sur
une disquette avant d'installer une OS sur le disque dur sélectionné. Consulter
la section "5.5 Créer une disquette du pilote RAID" pour plus de détails.
