Disk Modules
A disk module comprises a hard disk mounted in a carrier
(Figure 10)
. Each disk bay can
house a single low profile 1.0-inch high, 3.5-inch or 2.5-inch form factor disk drive in its
carrier. A fully loaded enclosure contains 84 disk modules.
The module handle provides the following functions:
• Camming of the module into and out of disk bays
• Positive “spring loading” of the disk/baseplane connector
There are two light pipes mounted in the carrier to transmit light from the two disk status
LEDs, located on the baseboard, to the surface of the carrier handle
(Figure 11)
. Refer to
Section
3.1.3 "Disk Locate and Status LEDs"
for more information.
The SS8460 supports a SAS-to-SATA bridge interposer which allows dual-ported access to
SATA disks and remote power control function for the disks.
Note that a SATA interposer
card, which is part of the disk drive carrier assembly, is required to run SATA
HDDs
