Standard SCSI Hard Disk Drive Bay RAID
Cabling Configuration
The RAID options available for your system provide your system with the
added security of fault tolerance.
If you order a system with a RAID controller, the system is pre-cabled at the
factory (see Figure C-3 "Standard SCSI Hard Disk Drive Bay RAID Cabling
Configuration".)
If you are adding a RAID controller you must install, cable, and configure the
controller. Refer to "Installing a RAID Controller Board" in Chapter 4.
One of the standard features of your server system is the three channel
SecuRAID 530 (Mylex eXtremeRAID 1100) controller board, which gives your
system the added security of fault tolerance. The RAID controller is installed in
PCI slot #2 and the third channel (2) is used to control the hot-swap hard disk
drives in the standard SCSI hard disk drive bay.
Channel A of the on-board Ultra 160/m SCSI controller AIC 7899 is not used
for the SCSI hard disk drive bays when the RAID controller is installed.
Figure C-3 illustrates the server RAID cabling configuration. For standard
cabling, see "Standard Cabling Configuration" earlier in this chapter. The RAID
controller (A) has a SCSI interface cable (B) that attaches to the backpanel (C)
at the rear of the standard SCSI hard disk drive bay (D) supporting up to five
SCSI SCA hard disk drives.
