Fujitsu MAF3364FC, MAG3091FC, MAG3182FC manual Standard Features

1.1Standard Features

(1)Compactness

The IDD has the FC-AL controller which supports the Arbitrated Loop (FC-AL) of the fibre channel modes defined by the ANSI standard, embedded in the 3.5-inch fixed disk drive form factor.

(2)FC-AL standard

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

∙Arbitration

∙Data frame CRC function

∙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

In order to support dual ports, the IDD is equipped with two pairs of fibre channel driver/receiver.

(4)High speed data transfer

The data transfer rate on the fibre channel loop is 106.25 MB/s maximum. In addition, the large capacity data buffer of the IDD allows the user to make full use of the high speed data transfer capability of the fibre channel loop.

(5)High speed spindle motor

The IDD increases the number of revolutions of the spindle motor from conventional 7,200 rpm to 10,025 rpm. Increasing the number of revolutions of the spindle motor will make it possible to improve the data transfer rate and reduce the rotation wait time.

(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.

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.
