Library with LTO Storage Cells
LTO Library Configurations
Caution – Firmware problems: You can not mix LTO and mixed-media arrays and
arrays within the same library. If you add expansion modules, the new modules must
have the same type arrays as the existing modules.
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 50 storage cells (see note), one or two tape drives, and a
five-cell cartridge access port (CAP).
Note – Only 30 of those storage cells can be used unless the cartridge upgrade
conversion bill has been installed, allowing the other 20 storage cells to be used. With
no upgrade, the first 30 storage cells after the reserved cells can be used for cartridge
storage. If the reserved storage cells are configured for storage, the numbering starts
there. The CAP cells also can be configured as storage cells.
■ Drive expansion modules and Cartridge Expansion Modules can be added to a
standard rack to accommodate various storage cell and tape drive configurations.
Note – You must have a 50-cartridge capacity base unit, either from the initial order or
with the upgrade conversion bill, before you can order an expansion module.
See Appendix A, “SL500 Wall Diagrams and Specifications” for detailed diagrams and
dimensions.
LTO 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.
1. Library number (always 0)
2. Library module number 1 (top of rack) through 5 (bottom of rack)
3. Row number 1 through 9 (Base Module) or 1 through 12 (expansion module)
4. Column number 1 through 9 for Base Module and Drive Expansion Module, 1
through 11 for Cartridge Expansion Module See “LTO Storage Cell and Drive
Capacities” on page 5 for more information.
