library-managed encryption

Tape encryption that is controlled by the tape library.

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 6250 GB (2.5:1

compression) and a native data capacity of up to 2500 GB.
