Drive carrier modules
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.
