Data Capacity And Recording Format - IBM TS2900 Setup, Operator, And Service Manual

Note: The Ultrium 4 Half Height tape drive in S4H libraries that are manufactured after March 2011
support 6.0 Gb/s.
The TS2900 Tape Autoloader has a 10-position removable cartridge magazine, providing a maximum of 9
data cartridge positions, or a maximum of 8 data cartridge positions with a configurable 1-slot I/O
station. One position is reserved as the tape drive exchange position and can be accessed by the library
only. The library data storage capacity can be further increased by using hardware compression.
See Table 3 for more information on supported tape cartridges in the TS2900 Tape Autoloader. WORM for
Ultrium 3 and later is also supported.
