Sample RAID Configuration
A RAID configuration might consist of the following:
• Pentium Pro 200 MHz Processor w/ECC Mem Support
• 128 MB System Memory
• PCI Ethernet Adapter (SMC8432BTA)
• PCI Token Ring Adapter (Olicom OC-3136)
• PCI RAID Adapter (Mylex)
• Four 4 GB SCSI wide hard drives connected to the Mylex RAID
controller
• SCSI CD-ROM drive connected to the onboard AIC-7880 SCSI
controller
Installing the Hardware
To install the hardware, follow these steps:
1. Combine the hot plug backplane.
2. Connect a wide SCSI cable between the Mylex PCI RAID adapter and the
top SCSI connector on the hot plug backplane. (If a wide SCSI cable is
connected between the system board and the top SCSI connector on the
hot plug backplane, remove this cable.)
3. Strap the CD-ROM drive as SCSI ID 3. Insert it into the top, front 5.25-
inch drive bay. Connect the power cable and the narrow SCSI cable to the
CD-ROM drive.
4. Strap the four 4 GB wide drives as SCSI IDs 0, 1, 2, 3. Plug them into the
hot plug backplane in drive bays 1, 2, 3, and 4 (top four hot-plug drive
bays).
5. Install the memory SIMMs in banks one and two on the system baseboard
(installed in groups of two SIMMs).
6. Install the PCI RAID Adapter in PCI slot 1 (topmost PCI slot).
7. Install the PCI Token Ring Adapter in PCI slot 2.
