4.5 RAID congurations
The motherboard comes with the AMD
®
Serial ATA hard disk drives as RAID sets. The motherboard supports the following RAID
• You must install Windows
®
XP Service Pack 2 or later versions before using Serial
ATA hard disk drives. The Serial ATA RAID feature is available only if you are using
Windows
®
XP SP2 or later versions.
• Due to Windows
®
XP / Vista limitation, a RAID array with the total capacity over 2TB
cannot be set as a boot disk. A RAID array over 2TB can only be set as a data disk
only.
• If you want to install a Windows
®
operating system to a hard disk drive included in a
RAID set, you have to create a RAID driver disk and load the RAID driver during OS
installation. Refer to section 4.6 Creating a RAID driver disk for details.
4.5.1 RAID denitions
RAID 0 (Data striping)
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
two new drives or use an existing drive and a new drive for this setup. The new drive must be
RAID 5 stripes both data and parity information across three or more hard disk drives. Among
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
and three new drives for this setup.
