SCSI DESCRIPTION

This chapter provides a detailed description of the logical interfaces of the tape drive. The drive is fully compliant with the ANSI SCSI-2 standard for tape drive devices and implements many optional features.

3.1SCSI OVERVIEW

The Small Computer System Interface (SCSI) is a specification for a peripheral bus and command set that is an ANSI standard. The standard defines an I/O bus that supports up to 16 devices (wide SCSI).

ANSI defines three primary objectives of SCSI-2:

1.To provide host computers with device-independence within a class of devices

2.To be backward-compatible with SCSI-1 devices that support bus parity and that meet conformance level 2 of SCSI-1

3.To move device-dependent intelligence to the SCSI-2 devices

Important features of SCSI-2 implementation include the following:

∙Efficient peer-to-peer I/O bus with up to 16 devices

∙Asynchronous transfer rates that depend only on device implementation and cable length

∙Logical addressing for all data blocks (rather than physical addressing)

∙Multiple initiators and multiple targets

∙Distributed arbitration (bus contention logic)

∙Command set enhancement
