5.5 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 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® 378ATA / 378SATA RAID driver using the Makedisk.exe utility before installing Windows® XP™ or 2000™ operating systems. • 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.

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 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
®
378ATA /
378SATA RAID driver using
the Makedisk.exe utility before
installing Windows
®
XP™ or 2000™ operating systems.
•
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.
