Expansion Modules
Expansion modules enable the library to expand by adding space for
tape drives, an I/E station, and storage. Each expansion module up to
the seventh expansion module adds from 300 to 456 LTO cartridge slots
depending on the number of tape drives installed and whether an I/E
station is installed. See
Figure 7 on page 16 for location information.
Quantum offers three different expansion modules (EMs) used with the
Scalar i6000:
• Drive Ready Expansion Module (DREM): This module is required
when drives will be installed into the module. It the power and
network components needed to support tape drives. The DREM
supports up to 12 tape drives and up to 456 cartridge slots, but the
slots are reduced when drives or an I/E station are installed in the
module.
• Storage Expansion Module (SEM): This module is used when
drives will not be installed in the module and high-density is not
needed. While the SEM does not support drives, it can be field
upgraded to a DREM if drives are needed in the future. The SEM
supports up to 456 cartridge slots, but the slots are reduced when
an I/E station is installed in the module.
• High-Density Expansion Module (HDEM): This module is used
when it is important to minimize the floor space. The HDEM
supports up to 780 cartridge slots, but does not support drives. The
slots are reduced when an I/E station is installed in the module.
Note: When referencing expansion modules in all Scalar i2000/i6000
documentation it includes all three module types: drive,
storage and high-density. When referencing standard
expansion modules, it includes just the drive-ready and storage
expansion modules.
In Gen 1 single-robot configurations, the library’s maximum
configuration includes up to 11 expansion modules for a total of 12
frames. In Gen 2 single-robot configurations, the library’s maximum
configurations includes up to 15 expansion modules for a total of 16
frames. In Gen 2 dual-robot configurations, the library’s maximum
configuration includes up to 15 expansion modules for a total of 17
frames (including the LPM and CM). Expansion modules can be added
