Redefining the Tape Transformation
Since its inception, tape has been a sequential (linear) access storage device. Though this proved beneficial for backup and many “high performance data streaming applications”, the ability to randomly navigate a tape cartridge to locate a specific file or object was inefficient. The LTFS™ (Linear Tape File System) Single Drive Edition (LTFS SDE) format was developed by IBM and adopted by the LTO Consortium (IBM, HPE, and Quantum) to address this challenge. On April 12, 2010, LTFS was announced at the National Association of Broadcasters (NAB) annual trade show for the LTO-5 standard tape format. The LTFS format specification is fully supported by the LTO roadmap which defines the specifications for the entire future LTO tape drive family. LTFS now provides a standard open file system for LTO drives, the latest enterprise TS11xx and T10000 drives from IBM and Oracle StorageTek, and tape libraries from several storage suppliers, further validating and expanding its value.
