Page 17: Chapter 1 General Description
CHAPTER 1 General Description Standard Features Hardware Structure System Configuration This chapter describes the feature and configuration of the hard disk drives (HDDs). The HDDs are high performance large capacity 2.5-inch hard disk drives with an embedded Serial Attached SCSI (SAS) controller. The interface used to connect the HDDs to the host system complies with ANSI T10/1601-D Serial Attached SCSI-1.1 (SAS-1.1), which covers items ranging from SAS physical layers to SCSI command protocols. - Page 18 General Description Dual SAS port support The HDDs have two pairs of driver and receiver set (PHY) for the SAS to support dual SAS port connection. On HDDs, Primary and Secondary Ports on SAS plug connector (2 physical links plus power connections) are used for SAS port connection.
- Page 19 1.1 Standard Features Command queuing feature The HDDs can queue maximum 128 commands, and optimizes the issuing order of queued commands by the reordering function. This feature realizes the high speed processing. (10) Reserve and release functions The HDDs can be accessed exclusively in the multi-host or multi-initiator environment by using the reserve and release functions.
- Page 20 General Description (16) Large capacity A large capacity can be obtained from the HDDs by dividing all cylinders into several partitions and changing the recording density on each partition (constant density recording). The disk subsystem with large capacity can be constructed in the good space efficiency. (17) Start/Stop of spindle motor Using the SAS primitive or the SCSI command, the host system can start and stop the spindle motor.

Page 21: 1.2 Hardware Structure
1.2 Hardware Structure Hardware Structure The HDDs have a disk enclosure (DE) and a printed circuit board assembly (PCBA). The DE includes heads on an actuator and disks on a spindle motor mounted on the DE. The PCBA includes a read/write circuit and a controller circuit. Disks The disks have an outer diameter of 54 mm (2.13 inch). -

SATA style cable SAS Plug Connector receptacle connector (SAS Device) SAS Initiator Device Power/LED Cable SAS Expander Device... - Page 23 1.3 System Configuration Port addressing Every device connected with the SAS protocol has a unique address (SAS address). SAS addresses are in the Name Address Authority (NAA) IEEE Registered format defined by SCSI Primary Command-2 (SPC-2). An SAS address consists of 8 bytes as a unique value set for each device. The initiator can implement an I/O operation on an HDD by using the corresponding SAS address stored by the HDDs.
