Automated Cartridge System Overview

The StorageTek Automated Cartridge System (ACS), called the library, is an automated storage and retrieval facility for tape cartridges. The library incorporates the Host Software Component (HSC) to accomplish automated mounting and dismounting of resident cartridges for the library-attached cartridge transports. The library may be attached to a maximum of 16 CPUs (hosts) with an HSC installed on each attached host system.

The library consists of four major elements:

•Host Software Component (HSC)— functions as the interface between the host operating system, and if applicable, a tape management interface (TMI).

•Library Storage Module (LSM)— contains storage cells for tape cartridges. The storage capacity of an LSM depends upon the LSM model. There are several LSM models available:

-Standard (Model 4410)

-PowderHorn (Model 9310)

-WolfCreek (Model 9360), which includes:

-9360-100 (1,000 cartridge capacity)

-9360-075 (750 cartridge capacity)

-9360-050 (500 cartridge capacity)

-TimberWolf (Model 9740)

-StreamLine (Model 8500).

An attached Library Control Unit (LCU) with associated electronics controls LSM robot movement. The LSM access door, contains a Cartridge Access Port (CAP), for entering or removing tape cartridges from the LSM. The types of CAPs available, depending upon how the LSMs are configured in an ACS, include:

-Standard and Enhanced CAP used in standard (4410) and PowderHorn (9310) LSMs.

-WolfCreek (9360) standard 20-cell and optional 30-cell CAPs. The WolfCreek LSM holds approximately 500, 750, or 1000 cartridges depending on the number of cartridge drives, pass-thru ports, and CAPs installed.
