Promise
The motherboard includes the Promise
support Redundant Array of Independent Disks (RAID) configurations.
Using two Serial ATA hard disks on the PRI_SATA / SEC_SATA interfaces,
and two ATA133 hard disks on the PRI_RAID interface, you may set up
RAID0, RAID1, RAID0+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).
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.
2. 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.
