Introduction

The TL881 MiniLibrary

This chapter describes the features of the MiniLibrary Expansion Unit, the
MiniLibrary Base Module, and the MiniLibrary Data Unit of the 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 drive with advanced robotics. The MiniLibrary
system is designed for high duty-cycle on-line and near-on-line applications,
such as hierarchical storage management (HSM). It is a superior performer in
high-volume backup and archival service as well.

Modules

The MiniLibrary system is based on three types of modules:

n

Expansion Unit (Master)

n

MiniLibrary Base Module

n

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-Thru Mechanism.
