What is LTFS? 1) Open Format for data which is written to tape è è Developed and disclosed by IBM Describes the format of data and meta data stored on tape Meta data is based on XML schema Applicable to LTO 5, LTO 6 and TS 1140 è Requires tape partitioning 2) File System support (code) to R/W tapes in LTFS format è Externalizes the LTO 5 / LTO 6 / TS 1140 tape as file system è Enables standard applications to write/read LTFS tapes è Supports update, edit, and delete of files on LTFS tape è Supports partial recall è Available on Linux, Mac OS X and Windows • 3 Makes tape look and work like any removable media (e. g. , USB drive, removable disk) © 2012 IBM Corporation

LTFS – Easy Exchange of Data – Share Data across Platforms LTO 5, LTO

LTFS-LE (Library Edition) Mount point is the library Cartridges are subdirectories LTFS mounts cartridges into drive to service file access requests Easy usage, no ISV required Caching of tape indices in memory – For searching and displaying tape contents without needing a mount Schematic Example 5 © 2012 IBM Corporation

Rich Media Archives Very Large – Large base of existing content to be digitized + continuous growth – Accessible by the media asset workflow tools & network – Scalability key Long term – 10 - 50+ years Self-describing data containers required – Out of system content management – Portability – need to distribute content to many users – Protection from loss of archive due to corruption/loss of central metadata/index 6 © 2012 IBM Corporation

LTFS Value Proposition Self-Describing cartridge – Remove requirement to commit long term to tape software application – Content protection in event of database corruption or loss Improve content interchange/distribution – Eliminate need for common tape software across enterprise and/or interchange locations – Reduce cost of data interchange vs provideo Partial Recall – Eliminate time penalty in moving large video content to tape in event of need small part of video content (ie. Goal in game) $/GB, Power – Reduce cost of digital storage – power and $/min Open Standards – Large diverse infrastructure requires open standard – Standard/support of MXF video Long Term Content Archive Life – Archive life desire for 50 -100 years 7 © 2012 IBM Corporation

Logical View of LTFS Volume LTFS utilizes media partitioning (new to LTO 5, LTO 6 and TS 1140) The tape is logically divided “lengthwise” • (think C: & D: drives on single hard disk unit) LTFS places the index on one partition and data on the other LTFS Index XML Index Partition Guard Wraps File B O T 9 File Data Partition File E O T © 2012 IBM Corporation
