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 drives are high performance large capacity 3.5" type hard disk drives with an embedded Fibre-Channel
controller.
The interface used to connect the drives to the host system complies with NCITS TR-19 Fibre Channel Private
Loop SCSI Direct Attach (FC-PLDA), which is the Fibre Channel PLDA standard covering items ranging
from Fibre Channel physical layers to SCSI command protocols.
The high-speed data transfer and long-distance transmission capabilities of Fibre Channel technology and the
powerful command set the HDDs facilitate creation of high-performance and highly reliable disk subsystems
with large storage capacities.
The data format can be changed from the format at factory shipment by re-initializing with the use's system.
Refer to Chapter 6 “Disc Media Management” of the Fibre Channel Interface Specification for details.
1.1 Standard Features
(1) Compactness
In a compact enclosure having the 3.5-inch HDD form factor, the HDD contains an FC-AL
controller, which supports the Arbitrated Loop technology (FC-AL), a Fibre Channel technology
defined by the related ANSI standard.
(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 Vehicle (ELV) Directive or
by the national environmental laws of the EU member nations.
(3) FC-AL standard
The HDD provides not only FC-AL basic functions but also the following features:
