CHAPTER 1 General Description
1.1 Standard Features
1.2 Hardware Structure
1.3 System Configuration
This chapter describes the feature and configuration of the hard disk drives (HDD).
The HDD are high performance large capacity 2.5" fixed disk drives with an embedded Serial Attached SCSI
(SAS) controller.
The interface used to connect the HDD 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.
The high-speed data transfer and long-distance transmission capabilities of SAS technology and the powerful
command set the HDD facilitate creation of high-performance and highly reliable disk subsystems with large
storage capacities.
