General Description

1.1Standard 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:

•Arbitration

•Disconnection/Reconnection

•Data bus parity

The SCSI commands can manipulate data through logical block addressing regardless of the physical characteristics of the disk drive. This allows software to accommodate future expansion of system functions.

(4)Dual-port support

The HDD has two pairs of driver and receiver sets for the Fibre Channel to support dual-port connection.

(5)High-speed data transfer

The maximum data-transfer speed on the Fibre Channel loop is 212.5 MB/s. The large-capacity data buffer of the HDD enables the effective use of such high-speed data transfers available on the Fibre Channel loop.

(6)Continuous block processing

The addressing method of data blocks is logical block address. The initiator can access data by specifying block number in a logically continuous data space without concerning the physical structure of the track or cylinder boundaries.
