Handling Media
To ensure that the library conforms to Dell specifications for reliability, use the Dell supplied LTO Ultrium Data Cartridge. See Figure 1 . Other LTO
certified media may be used, but it may not meet the standards of reliability established by Dell.
The data cartridges are housed in plastic cases and employ half-inch metal particle tape that has a native capacity of 100GB and a compressed
capacity of 200GB (assuming average 2:1 compression). The cartridge also contains a Linear Tape Open Cartridge Memory (LTO-CM) chip,
which contains information about the cartridge and the tape. The information includes the name of the manufacturer who created the tape, the
cartridge volume serial (volser) number, statistical information about the cartridge use, and a directory of the data on the tape.
