Electrical Interface
7.1
SAS Connector
The drive uses the standard 29 pin Serial Attached SCSI (SAS) connector which conforms to the mechanical
requirements of SFF 8680. The connector is expected to be used in an environment which uses a common
connector structure for racking disk drives in a cabinet. The connector allows for plugging a drive directly into a
backplane by providing the necessary electrical connection. Mechanical stability and device retention must be
provided by a mechanism outside the drive.
