Understanding the Major Components

When the partitioning feature is enabled, each hosted application controls one half of
the storage cells and one half of the drives in the SL150 library. Partition 1 controls the
storage slots on the left side and any drives installed in the top drive bays of the
library modules. Partition 2 controls the storage slots on the right side and any drives
installed in the bottom drive bays. Note that you can have varying numbers of drives
in your partitions as long as each partition contains at least one bridged drive for
communication with the host.
When partitioning is enabled, the partitions share a common robot and mailslot while
keeping their respective media separate. Whenever a shared resource handles media
assigned to a partition, the corresponding partition host has exclusive control over the
resource.

Browser-Based Administration and Monitoring

The basic user interface to the library is a web application that can be accessed from
any workstation that has a network connection and an installed web browser. There is
nothing that has to be separately downloaded, locally installed, or locally managed.

Customer Serviceability

The StorageTek SL150 Modular Tape Library is designed for straightforward
maintenance and servicing.
Users can, in most cases, troubleshoot and repair their equipment without assistance.
Library components are organized into a limited number of Customer Replaceable Units
(CRUs), each of which has a discrete function in the library. Faults are automatically
isolated within the confines of the unit. If any part fails, the whole fails, and the user
simply replaces the entire CRU with an equivalent unit.
CRUs can be installed and removed in a few simple steps, using simple hand tools. In
the SL150 library, CRUs are secured to the chassis with captive thumb screws and
thumb latches that can be removed and installed using, at most, a Phillips screw
driver.
More routine tasks have also been streamlined. Tapes can be rapidly bulk loaded and
unloaded to facilitate capacity upgrades, reconfiguration, vaulting, or any other
operation that cannot be efficiently managed using the mailslot. Each SL150 library
module stores cartridges in two, 15-cell, detachable magazines that you can unlatch
and draw out of the front of the module, like a drawer.

Panel and a
access over your network.

Modular Hardware

A typical SL150 installation contains a base module and optional expansion modules
installed under the base unit. Base and expansion modules share the same storage
layout: one or two rear-mounted drives installed one above the other on the center line
of the chassis and two drawer-style, front-loading tape magazines at the front, on
either side of the chassis. The space between the magazines is reserved for robotic
library operations.
