AMD RAID Configuration

RAID configurations

If your motherboard supports RaidXpert2 Configuration Utility, you can create Volume,
RAIDABLE, RAID 0, RAID 1, or RAID 10 (depends on system licensing) configurations.
Please refer to your motherboard's user manual for details on the actual supported RAID
configurations.
If you want to install a Windows
set, you have to create a RAID driver disk and load the RAID driver during OS installation.
Refer to section 1.2 Creating a RAID driver disk for details.

RAID definitions

Volume provides the ability to link-together storage from one or several disks, regardless
of the size of the space on those disks. This configuration is useful in scavenging space on
disks unused by other disks in the array. This configuration does not provide performance
benefits or data redundancy, disk failure will result in data loss.
RAIDABLE arrays (also known as RAID Ready) are a special type of Volume (JBOD) that
allows the user to add more storage space or create a redundant array after a system is
installed. RAIDABLE arrays are created using Option ROM, UEFI, or rcadm.
The ability to create RAIDABLE arrays may vary per system.
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 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.
