LTO Storage Cell and Drive Capacities

Note – Your software might conflict with the following information. Refer to your software publication for unique information.

TABLE 1-1shows the number of cartridge and tape drive slots available depending on the type and number of modules installed. The table assumes that, when DEMs and CEMs are installed in the same library, the DEMs are above all of the CEMs, as preferred.

Note – Do not install an EZ DEM below an original CEM. This is not physically allowed.

The following notes are factors that influence capacity:

1.When you add an expansion module below an existing module, you increase the capacity of the module directly above it by:

■Base module: +16 storage cells

■CEM (when another CEM is below it): +10 storage cells

■DEM: +7 storage cells

2.When a CEM is installed below a Base Module or DEM, the top two rows on columns 9, 10, and 11 of the CEM are not accessible (-6 storage cells because the tape drives prevent the hand from reaching the cells).

3.The lowest module in the rack requires installation of the floor. The floor limits the distance the robot can travel, which makes the bottom row(s) in the lowest module inaccessible:

■Base module: -16 storage cells

■DEM: -7 storage cells

■CEM (below another CEM): -16 storage cells (-10 storage cells on the lowest CEM, -6 storage cells on the CEM above it)

■CEM (below Base Module or DEM): -16 storage cells

4.Cartridge access ports:

■Base module: 5 storage cells (one magazine)

■Each DEM: 10 storage cells (two magazines)

■Each CEM: 10 storage cells (two magazines)
