Raid Configurations - Asus SK8N User Manual

RAID configurations

The motherboard includes the Promise
support Redundant Array of Independent Disks (RAID) configurations.
Using two Serial ATA hard disks on SATA_RAID1/SATA_RAID2 interfaces,
and two ATA133 hard disks on the PRI_RAID interface, you may set up
RAID 0, RAID 1 and RAID 0+1 configurations. Use the MBFastTrak378™
BIOS and the FastBuild™ utility to configure a disk array.
RAID 0 (called 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.
RAID 1 (called 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.
RAID 0+1 is data striping and data mirroring combined without parity
(redundancy data) having to be calculated and written. The advantage of
RAID 0 + 1 is fast data access (like RAID 0), but with the ability to loose
one drive and have a complete duplicate surviving drive or set of drives
(like RAID 1).
• Make sure to create a floppy disk with the Promise
378SATA RAID driver using the Makedisk.exe utility before
installing Windows
5-25 for details.
• Refer to the FastTrak 378 Quick Start Guide and SATA Quick
Start Guide found in "/Manual" of the support CD for detailed
information on RAID configurations under different operating
systems.
