IBM® Linear Tape File System™ (LTFS) provides direct, intuitive and graphical access to data stored in IBM tape drives and libraries using Linear Tape-Open (LTO) Ultrium 6 or 5 tape cartridges, as well as IBM 3592 tape cartridges in libraries with IBM TS1150 or IBM TS1140 tape drives. It eliminates the need for additional tape management and software to access data.
LTFS is a significant step in moving tape storage away from its reputation as complex and difficult to use. Unlike disk storage, tape has previously required device-specific software to read, write and manage data stored on its cartridges in libraries. But LTFS is the first file system that works in conjunction with LTO Ultrium tape technology to set a new standard for ease of use and portability for open-systems tape storage. Users can run any application designed for disk files against tape data without concern for the fact that the data is physically stored on tape.
