Drive Carrier Module in 2U Chassis
The drive carrier module comprises a hard disk held by a carrier.
• Each 2U12 drive slot holds a single low profile 1.0-inch high, 3.5-inch form factor drive in its
carrier.
• The drives are horizontal.
• The 2U12 chassis accommodates 3.5” SAS and 3.5” SATA drives.
• A special interposer is required for SATA drives (included with the SATA drive and its carrier
when purchased).
• Each 2U24 drive slot holds a single low profile 5/8-inch high, 2.5-inch form factor disk drive in its
carrier.
• The drives are vertical.
• The 2U24 chassis accommodates 2.5” SAS or SATA drives.
• A special interposer is required for SATA drives (included with the SATA drive and its carrier
when purchased).
The carriers have mounting locations for:
• Direct dock SAS drives.
• A sheet steel carrier holds each 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 slots.
• Positive spring-loading of the drive/midplane connector.
• The carrier can use this interface:
• Dual path direct dock Serial Attached SCSI.
Populating 2U12 Chassis with Drives
The 2U12 chassis ships with drives installed. Please review these rules:
• The minimum number of drives supported by the chassis is 1.
•
Hard disk drives (HDD) and solid state drives (SDD) can be mixed in the chassis.
NOTE: If the chassis has no drives installed, always install the first drive into slot 0, and then
populate slots 1-11 sequentially with any additional drives.
Integers on the drives indicate drive slot numbering sequence (0-11). Figure 50 provides a front view
of the 2U12-drive chassis fully populated with drives.
