Exabyte EXB-8505 8mm Scsi Features, Physical Path, Data Transfer Rate, Interface Specifications

5Interface Specifications

SCSI Features

Implementation characteristics of the Small Computer System

Interface (SCSI) controller include the following:

Support for single-ended or differential SCSI configurations.

SCSI bus parity checking configurable through the MODE

SELECT command.

Support for multiple initiator configurations.

Support of the disconnect, reconnect, and arbitration feature, which releases the tape drive from the bus so that it can operate under its own internal intelligence system, enabling the SCSI bus to perform other I/O requests.

The SCSI implemented for the tape drive conforms to the following standard for a sequential access device: ANSI Small Computer System Interface-2(SCSI-2), X3.131-1994.

Data Transfer Rate

The maximum obtainable data transfer rates for the tape drive depend on what mode it is operating in. For information on data transfer rates, see Chapter 6.

Physical Path

The physical path implemented by the tape drive includes an eight-port, daisy-chained bus with the following features:

Single-host or multiple-host computer system capability

Bus contention handled by distributed arbitration on a prioritized basis

Accommodation of multiple peripheral device types

Multiple overlap of peripheral device operations

Orientation toward intelligent peripheral devices

Enhanced operation with buffered devices
