Redefining the Tape Transformation
Since its inception, tape has been a sequential access storage device. Though this proved beneficial for backup and many “data streaming applications”, the ability to randomly navigate a tape cartridge to locate a specific file or object was physically impossible. The LTFS™ Single Drive Edition (LTFS SDE) format was developed by IBM to address tape archive requirements and first announced at the National Association of Broadcasters (NAB) annual trade show on April 12, 2010 for the LTO-5 standard tape format. The LTFS format specification was adopted by the LTO Consortium (IBM, HP, and Quantum) and is supported by the LTO roadmap which defines the specifications for the LTO tape drive family. LTFS provides, for the first time, tape partitioning functionality for LTO-5 and follow-on LTO drives, the latest enterprise TS11xx and T10000 tape drives from IBM and Oracle StorageTek, and tape libraries from several storage suppliers, further validating and extending its value.
