SCSI Configuration: Dell PowerEdge 6350 Systems
SCSI Configuration: Dell™ PowerEdge™ 6350 Systems
Integrated SCSI Controllers | SCSI Hard-Disk Drives | Configuration Guidelines
Two integrated Adaptec AIC-7890 Ultra2/LVD SCSI host adapters support up to three
1-inch internal SCSI hard-disk drives. Connections are accomplished through two 68-pin
connectors on the system board that connect to the SCSI backplane board. The SCSI
backplane board automatically configures SCSI ID numbers and SCSI termination on
individual hard-disk drives, greatly simplifying drive installation. The integrated SCSI
controllers reside on the PCI local bus for optimum performance.
An integrated Adaptec AIC-7860 Ultra/Narrow SCSI host adapter attached to the PCI bus
supports the CD-ROM drive through a 50-pin connector on the system board.
Dell PowerEdge 6350 systems include a SCSI backplane board, which
greatly simplifies cabling and configuration for SCSI hard-disk drives. SCSI ID and
termination for SCSI hard-disk drives are both configured by the SCSI backplane board,
rather than on individual drives.
All Dell PowerEdge 6350 systems have an active terminator installed at
the end of the SCSI cable; therefore, all devices attached to the cable should have their
termination disabled.

NOTE: For maximum performance, install
Ultra2/LVD drives exclusively. Although you can install a mixture of Ultra2/LVD and Ultra
hard-disk drives, they will operate at the slower Ultra transfer rate. |
SCSI hard-disk drives must be configured as follows:
- Disable termination on the drive. The SCSI backplane board provides termination for the
SCSI bus.
- Set the SCSI ID on the drive to 0. All hard-disk drive SCSI ID numbers are set by the
SCSI backplane board.
- Configure the drive so that the drive motor waits for a start unit
command from the SCSI host adapter before spinning.
The CD-ROM drive should be set to SCSI ID 5, and its termination should be disabled.
