System Description

Introduction

This chapter describes the features of the Expansion Unit, the Base Module,

and the Data Unit of the Compaq StorageWorks TL881/TL891 Family

MiniLibrary System

, including storage architecture, SCSI interface, bus

performance, and physical configuration/expansion options.

The MiniLibrary system is an expandable, modular tape library system that

combines DLT technology drives with advanced robotics. The MiniLibrary

system is designed for high duty-cycle on-line and near-on-line applications. It

is a superior performer in high-volume backup and archival service.

Modules

The MiniLibrary system is based on three types of modules:

■

Expansion Unit (master)

■

MiniLibrary Base Module

■

Data Unit

The MiniLibrary system consists of one Expansion Unit and up to five

MiniLibrary Base Modules and Data Units in combination stacked in a rack.

The Expansion Unit can move media freely between itself, the MiniLibrary

Base Module, and the Data Unit by way of the system’s robotically controlled

Pass-Through Mechanism (PTM).
