The ability to copy a large file or a large selection of files (up to 1.5TB uncompressed data for LTO-5, and 18TB for LTO-9) to an LTFS formatted tape, allows easy exchange of data to a collaborator, or the saving of an archival copy. Since LTFS is an open standard, LTFS formatted tapes are usable by a wide variety of computing systems and ...
The IBM Ultrium 6 technology is designed to support media partitioning, IBM Linear Tape File System (LTFS) technology and encryption of data and WORM cartridges. [ 41 ] TS2260 – Half-height external standalone or rack mountable shelf unit with a native physical capacity of 2.5 TB.
FlashCopy is an IBM feature supported on various IBM storage devices that made it possible to create, nearly instantaneously, point-in-time snapshot copies of entire logical volumes or data sets. [1] The Hitachi Data Systems implementation providing similar function was branded as ShadowImage. Using either implementation, the copies are ...
James T, Brady while in IBM Poughkeepsie Lab conceived a log structured paging file system in 1979 which was implemented in MVS SP2 in 1980. [1] [2] John K. Ousterhout and Mendel Rosenblum implemented the first log-structured file system for the Sprite operating system in 1992. [3] [4]
Linear Tape-Open (LTO), also known as the LTO Ultrium format, [1] is a magnetic tape data storage technology used for backup, data archiving, and data transfer.It was originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats available at the time.
Its early versions supported IBM mainframe and midrange including IBM System 38 and AS/400, Windows, Apple, UNIX, Digital Equipment Corporation VAX, Data General, Stratus, Tandem, and others, for many decades and functions on both SNA and TCP/IP networks.
Extended Remote Copy or XRC is now known as Global Mirror for z/Series (XRC). XRC is a z/Series asynchronous disk mirroring technique which is effective over any distance. It keeps the data time consistent across multiple ESS (Enterprise Storage Server) or HDS (Hitachi Data Systems) disk subsystems at the recovery site.
The StorNext Storage Manager is a policy based data management system that can copy, migrate and/or archive data from the StorNext File System into a variety of storage devices in multiple locations. Data can be tiered into disk, a Quantum Lattus object store, a robotic tape library, or even exported into an offline vault.
