Hard Drives

Your system includes up to two hard drives and are located on one side of the server module. The hard drives are secured to the server module using four 6-32 x 0.25 hex-head Phillips screws. The hard drives input power connector is connected to the SCSI PWR connector located on the server module board. The hard drives SCSI data cable is connected to the SCSI connector located on the server module board.

Integrated Mirroring of SCSI Hard Drives

The SCSI controller on the server module board supports integrated mirroring if two SCSI drives are installed.

Follow these guidelines to implement integrated mirroring on your server module:

NOTE: Dell strongly recommends that you use Dell OpenManage™ Array Manager to enable and configure integrated mirroring.

For more information on this feature, see the integrated mirroring documentation provided with your system.

SCSI Configuration Information

Although SCSI drives are installed in essentially the same way as other drives, their configuration requirements are different. To install and configure a SCSI drive, follow the guidelines in the following subsections.

SCSI Interface Cables

SCSI interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends. When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.

SCSI ID Numbers

Each drive attached to a SCSI controller must have a unique SCSI ID number from 0 to 15.

NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that drives be attached to the cable in order by ID number.
Device Termination

SCSI logic requires that termination be enabled for the two drives at opposite ends of the SCSI chain and disabled for all drives in between. For internal SCSI drives, termination is configured automatically. See the documentation provided with any optional SCSI drive you purchase for information on disabling termination.

Removing Hard Drives

CAUTION: Before you perform this procedure, see "Safety First—For You and Your System" in "Troubleshooting Your System."
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information Guide.
