Stand-alone tape management systems are predominant on mainframe platforms where tape is used as both a backup and base load storage medium.. Mainframe systems such as IBM's z/OS do provide some basic support for tape inventory control via the OS Catalog but as cataloging files is optional it is usually required that an additional software package does the following:
Advanced Digital Information Corporation (ADIC) was an American manufacturer of tape libraries and storage management software which is now part of Quantum Corp. Their product line included both hardware, such as the Scalar line of robotic tape libraries, and software, such as the StorNext File System and the StorNext Storage Manager, a Hierarchical Storage Management system.
oracle.com /storage /tape-storage / Storage Technology Corporation ( StorageTek or STK , earlier STC ) was a data storage technology company headquartered in Louisville, Colorado . [ 1 ] New products include data retention systems, which it calls "information lifecycle management" (ILM).
At the end of the tape, the drive reversed the direction of tape motion, moved the read and write heads slightly vertically across the tape, and continued to write (or read) more data until the beginning of the tape was reached. This process could be repeated many times, laying down several track sets on the tape media in a serpentine recording ...
The IBM 726 was IBM's first magnetic tape unit. It was a dual magnetic tape reader/recorder developed for use with the IBM 701 and announced on May 21, 1952. This model of tape unit was shipped with the IBM 701 from December 20, 1952 until February 28, 1955. [1] Unlike later IBM 7 track drives, the 726 could read backwards as well as forwards.
Mainframe Virtual Tape (MVT) [7] is a family of products that are composed of one or more MVT controllers as well as internal SAS (MVTi) or Fibre Channel attached (MVTe) storage. The number of controllers in an MVT configuration is a dependent on the users' availability and throughput requirements.
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of 7-track , later 9-track tape.
A direct-access storage device (DASD) (pronounced / ˈ d æ z d iː /) is a secondary storage device in which "each physical record has a discrete location and a unique address". The term was coined by IBM to describe devices that allowed random access to data, the main examples being drum memory and hard disk drives . [ 1 ]
