Linear Tape-Open (LTO)
A type of tape storage technology that is developed by the IBM Corporation, Hewlett-Packard,
and Quantum. LTO technology is an “open format” technology, which means that its users have
multiple sources of product and media. The “open” nature of LTO technology enables
compatibility between different vendors' offerings by ensuring that vendors comply with
verification standards. The LTO technology is implemented in two formats: the Accelis format
focuses on fast access; the Ultrium format focuses on high capacity. The Ultrium format is the
preferred format when capacity (rather than fast access) is the key storage consideration. An
Ultrium cartridge has a compressed data capacity of up to 15 TB (2.5:1 compression) and a native
data capacity of up to 6 TB.
