General Description

•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.

The continuous processing up to [64K-1] blocks in a command can be achieved, and HDD can perform continuous read/write operation when processing data blocks on several tracks or cylinder.

(7)Multi-segment data buffer

The data buffer is 8M bytes. Data is transferred between Fibre Channel Loop and disk media through this data buffer. This feature provides the suitable usage environment for users.

Since the initiator can control the disconnect/reconnect timing on the Fibre Channel Loop by specifying the condition of stored data to the data buffer or empty condition of the data buffer, the initiator can perform the effective input/output operations with utilizing high data transfer capability of the Fibre Channel Loop regardless of actual data transfer rate of the disk drive.

(8)Cache feature

After executing the READ command, the HDD reads automatically and stores (prefetches) the subsequent data blocks into the data buffer (Read-ahead caching).

The high speed sequential data access can be achieved by transferring the data from the data buffer without reaccessing the disk in case the subsequent command requests the prefetched data blocks.

The Write Cache feature is supported. When this feature is enabled, the status report is issued without waiting for completion of write processing to disk media, thereby enabling high speed write processing.
