1.1

Standard Features

(1)

Compactness

In a compact enclosure having the 3.5-inch HDD form factor, the IDD contains an FC-AL controller,

which supports the Arbitrated Loop technology (FC-AL), a Fibre Channel technology defined by the

related ANSI standard.

(2)

FC-AL standard

The IDD provides not only FC-AL basic functions but also the following features:

•

Arbitration

•

Disconnection/Reconnection

•

Data bus parity

•

Command set which meets the logical specification of the SCSI CCS (Common Command Set

for Direct Access Device) requirements (Rev. 4.B)

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.

(3)

Dual-port support

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

connection.

(4)

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 IDD enables the effective use of such high-speed data transfers available on the Fibre

Channel loop.

(5)

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.

The continuous processing up to [64K-1] blocks in a command can be achieved, and IDD can perform

continuous read/write operation when processing data blocks on several tracks or cylinder.
