Drive carrier modules

Edit online

The drive carrier module comprises a hard disk held by a carrier.

  • Each drive bay holds a single low profile 1.0 inch high, 3.5 inch form factor disk drive in its carrier. Drives are horizontal.

A sheet steel carrier holds each disk drive: which provides thermal conduction, radio frequency and electro-magnetic induction protection and physically protects the drive.

The front cap also has an ergonomic handle which gives the following functions:
  • Secure location of the carrier into and out of drive bays.
  • Positive ‘spring loading’ of the drive/mid plane connector.
The carrier can use these interfaces:
  • Serial Attached SCSI.

Drive status indicators

Green and amber LEDs on the front of each drive carrier module indicate Disk drive status as shown in the figure below. The SEP controls these LEDs, see the section that describes these LEDs’ states.

Anti-tamper locks

The drive carrier handles have Anti-tamper locks, as shown below in the figures, which are accessed through the small cutout in the latch section of the handle. These locks disable the normal ‘pinch’ latch action of the carrier handle.
