Encyclopedia
Transarc Corporation was a private Pittsburgh-based software company founded in 1989 by Jeffrey Eppinger
, Michael Kazar, Alfred Spector
, and Dean Thompson of Carnegie Mellon University
. It commercialized the Andrew File System
(AFS) that was originally developed at Carnegie Mellon.
As a member of The Open Group
, Transarc also developed the DFS
distributed filesystem component of the Distributed Computing Environment
(DCE) that was sold by Open Group members (including Transarc). Other products included the distributed transaction processing monitor Encina (a basis for IBM's UNIX-based CICS
products; included in IBM's TXSeries and later WebSphere
), and the Solaris binary distribution of DCE.
Transarc was purchased by IBM in 1994 and became the IBM Pittsburgh Lab in 1999. In 2000, IBM announced OpenAFS
, an open source version of the Transarc AFS implementation. The commercial version is now deprecated.
