Configuration Overview
1-2 StorageTek SL150 Modular Tape Library Installation Manual
Configuration Overview
The minimum configuration consists of a 3U base module, designated Module 1,
containing: the front control panel, one robotic hand, a mailslot with four slots, a
power supply, and one tape drive (with options to add a second drive tray, a second
power supply, or both). It stores up to 30 tapes in two, removable 15-slot magazines
(one on each side of the module). You can designate up to three reserved slots in the
base module left magazine for storing cleaning or diagnostic tapes.
You can add 2U expansion modules to provide additional tape slot capacity (see
Figure 1–1). Expansion modules two through ten connect to the base module by an
expansion cable that has USB Type A connectors. The expansion module controller
receives power over the expansion cable.
Expansion modules ship without tape drive trays or power supplies. When the first
tape drive tray is installed in an expansion module, a power supply must also be
installed to provide power for the tape drive. A second power supply can be added for
redundancy. One power supply provides adequate power for two tape drive trays.

Maximum library cartridge capacity depends on the base module hardware revision
level and software version:
■ Hardware revision level 12 and 3.00 software supports one to 15 modules, one to
450 tape cartridges, and one to 30 tape drives. A 15 module library uses 31 U
(1206.5 mm [47.5 inches] of rack space.
■ Hardware revisions levels up to 11 and software levels up to 2.6 support one to 10
modules, one to 300 tape cartridges, and one to 20 tape drives. A 10 module
library uses 21U (933.5 mm [36.75 inches]) of rack space.
Note: There is an expansion cable in the accessory package which is
located in the expansion module carton.
