General Description
The Scalar 1000 automates the storage, retrieval, and control 
of 3590, LTO, DLT, SDLT, and AIT cartridge tapes. Cartridges 
are mounted and dismounted in tape drives using application 
software from the host without operator intervention.
The Scalar 1000 is a linear storage library that can be expanded 
from a single media library to a mixed media library. The 
Scalar 1000 consists of a Control Module (CM) and up to three 
Expansion Modules (EMs). See Figure 2-1 on page 2-5. The 
CM contains library control hardware, the Cartridge 
Accessor, an Insert/Eject Station (I/E) Station, an Operator 
Panel, cartridge storage cells, and tape drives. The EM can 
contain tape drives and cartridge storage.
The Scalar 1000 can be configured for approximately 
118 to 1182 cartridges (the cartridge capacity depends on the 
library configuration and features installed). See Table 2-1.

Note
If the ADIC 8590/
IBM 3590 tape 
drive is installed in 
either the Control 
or the Expansion 
Module, the 
modules must be of 
the large footprint 
type. Adding an 
extension frame to 
a normal frame 
increases the depth 
of the frame.
