Hardware Installation
The system board is equipped with one shrouded RAID IDE
header that will interface two Enhanced IDE (Integrated Drive
Electronics) disk drives. To prevent improper IDE cable installa-
tion, the shrouded RAID IDE header has a keying mechanism. The
40-pin connector on the IDE cable can be placed into the
header only if pin 1 of the connector is aligned with pin 1 of the
header.
Hard drives must be Ultra ATA/133, ATA/100, Ultra ATA/66, Ultra
ATA/33, EIDE and/or Fast ATA-2 compatible. For optimal perform-
ance, install identical drives of the same model and capacity. The
drives’ matched performance allows the RAID array to function
better as a single drive.
Drives in an array must be identical. If striping for performance,
use two new drives. If mirroring for protection, you can use two
new drives or use an existing drive and a new drive (the new
drive must be the same size or larger than the existing drive).
Only two drives can be configured as RAID. Since striping or
mirroring is done on the same channel, one drive must be set in
Master mode and the other in Slave mode.
