RAID configurations
The motherboard includes the Promise
®
PDC20378 controller chipset to
support Redundant Array of Independent Disks (RAID) configurations.
Using two Serial ATA hard disks on SATA_RAID1/SATA_RAID2 interfaces,
and two UltraDMA133 hard disks on the PRI_RAID interface, you may set
up RAID 0, RAID 1, RAID 0+1, and Multi-RAID 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).
• If you use either Windows
®
XP or Windows
®
2000 operating
system (OS), copy first the Promise FastTrak 378 Driver from the
support CD to a floppy disk before creating RAID configurations.
• Refer to the FastTrak 378 Quick Start Guide and SATA Quick
Start Guide in the support CD for detailed information on RAID
configurations under different operating systems.
