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

Modules

The MiniLibrary system is based on three types of modules:

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).
