ABOUT THIS MANUAL

“About this Manual” outlines the scope and contents of this manual. It contains information about
the intended audience, purpose of the manual, document organization, and document conventions.

AUDIENCE

This manual is written for original equipment manufacturers (OEMs) that are

integrating this Quantum DLT family tape drive into a system or subsystem.

Its primary audience is the OEM technical staff that makes tape drive purchase
and configuration decisions, and system integrators that are responsible for the
SCSI interface. Additionally, the manual can be used by technically astute end­users for installation and operation of the tape drive, although that is a
secondary audience.

PURPOSE

This manual describes the rackmount and tabletop versions of the DLT 7000
tape system. It is intended to provide the information necessary to integrate the
tape drive into a computer system or subsystem.

DOCUMENT ORGANIZATION

This product manual contains five chapters, a number of appendices of related
useful information, and an index. It includes an overview of the Small Computer
System Interface (SCSI) and detailed descriptions of the messages and SCSI
commands as used by the tape drive. The manual is organized as follows:

Chapter 1 General Description and Specifications

This chapter contains a brief description of and specifications for the
drive.

Quantum DLT 7000 Tape System xxi

About This Manual

Chapter 2 Hardware Implementation

This chapter contains configuration and installation information for the
tape drive, descriptions of the drive controls and LEDs, and information
on running the self-test.

Chapter 3 SCSI Description

This chapter provides a detailed description of the logical interfaces of
the tape drive. It describes the product’s compliance with the ANSI
SCSI-2 specification. The drive’s many optional features are described
here and throughout the manual.

Chapter 1

GENERAL DESCRIPTION AND SPECIFICATIONS

This chapter provides a description and gives specifications for the Quantum DLT™7000 Tape
System.

1.1 PRODUCT DESCRIPTION

The Quantum DLT 7000 tape system is a high-performance, high-capacity,

streaming cartridge tape system designed for efficient data back-up for midrange
and high-end computing systems. With Quantum’s DLT advanced linear
recording technology, a highly accurate tape guide system, and an adaptive
control mechanism, the drive is ideally suited for mid-range systems, network
servers, and high-end workstations and systems.

Using data compression, the DLT 7000 tape system features a formatted
capacity of 70.0 GB* and a sustained user data transfer rate of 10 MB/second*
(native capacity is 35.0 GB; native data transfer rate is 5.0 MB/second).

The device is an extended-length, 5.25-inch form factor, half-inch cartridge tape
drive. The design includes a four-channel read/write head, Lempel-Ziv (LZ)
high-efficiency data compression, and tape mark directory to maximize data
throughput and minimize data access time.

The system is available either as an integratible or “embedded” drive or as a
tabletop version. The tabletop version is packaged in housing that includes its
own cooling fan and power supply, requiring ac power.
