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 (HDDs).
The HDDs are high performance large capacity 3.5" fixed 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.
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.
1.1 Standard Features
(1) Compactness
The HDDs are a compact enclosure which complies with the 3.5" disk drive form factor.
(2) Restriction of Use of Hazardous Substances
The amounts of hazardous substances in use in these HDDs have been reduced in accordance with the
Restriction of Use of Hazardous Substances (RoHS) Directive recently issued by European Union (EU).
Note:
At present, the permissible limits on the use of certain materials specified by the RoHS
directive have not been determined. In such cases, we are using the original criteria set by
Fujitsu Limited while referring to the restrictions already established by End-of-Life (ELV)
Directive or by the national environmental laws of the EU member nations.
