Library with Mixed-Media Storage Cells

Mixed-Media Library Configurations

Caution – Firmware problems: You can not mix LTO and mixed-media arrays and
magazines within the same library. If you add expansion modules, the new modules
must have the same type arrays as the existing modules.
Note – Your robotics unit must be part number 314558705 or higher to read SDLT
cartridge labels.
For each library:
The Base Module contains the robotics unit and the base unit:
■
The robotics unit has the robotic components and the keypad
■
The base unit has up to 42 storage cells (see note), one or two tape drives, and a
■
four-cell cartridge access port (CAP).
Note – The base unit can be ordered originally as a 24- or 42-cell unit. If you received
the 24-cell version, only 24 of those storage cells can be used unless the upgrade
conversion bill has been installed. Without a conversion bill, the first 24 cells after the
reserved cells can be used for cartridge storage. If the reserved cells are configured for
storage, the numbering starts with the first physical cell on the left.
An upgrade conversion bill allows the other 18 storage cells in the base unit to be
used, for a total of 42. This conversion bill is for customers who want only the base
unit and do not expect to order an expansion module.
The CAP cells can also be configured as storage cells.
Drive expansion modules (DEMs) and Cartridge Expansion Modules (CEMs) can be
■
added to a standard rack to accommodate various storage cell and tape drive
configurations.
Note – You must have a 42-cartridge capacity base unit before you can order an
expansion module.

dimensions.

Mixed-Media Library Internal Addressing

The numbering scheme uses the library, module, row and column scheme. Four
integers are used to represent the cartridge and tape drive slots, as viewed from the
front of the library.
