Transarc
Transarc Corporation was a private Pittsburgh-based software company founded in 1989 by Jeffrey Eppinger, Michael L. Kazar, Alfred Spector, and Dean Thompson of Carnegie Mellon University. Transarc commercialized the Andrew File System (AFS), now OpenAFS, which was originally developed at Carnegie Mellon. As a member of the Open Software Foundation (later The Open Group), Transarc developed the DFS distributed filesystem component of the Distributed Computing Environment (DCE) that was sold by Open Group members. Other products included the distributed transaction processing system Encina (a basis for IBM's UNIX-based CICS products; included in IBM's TXSeries and later WebSphere), and the Solaris binary distribution of the DCE. Transarc was purchased by IBM International Business Machines Corporation (using the trademark IBM), nicknamed Big Blue, is an American Multinational corporation, multinational technology company headquartered in Armonk, New York, and pre ...

Alfred Spector
Alfred Zalmon Spector is an American computer scientist and research manager. He is a Professor of Practice in the MIT EECS Department and was previously CTO of Two Sigma Investments. Before that, he was Vice President of Research and Special Initiatives at Google. Education Spector received his Bachelor of Arts degree in Applied Mathematics from Harvard University, and his PhD in computer science from Stanford University in 1981. His research explored communication architectures for building multiprocessors out of network-linked computers and included measurements of remote procedure call operations on experimental Ethernet. His dissertation was titled ''Multiprocessing Architectures for Local Computer Networks'', and his advisor was Forest Baskett III. Career Spector was an associate professor of computer science at Carnegie Mellon University (CMU). While there, he served as doctoral advisor to Randy Pausch, Jeff Eppinger and Joshua Bloch and seven others. Spector was a fo ...

OpenAFS
OpenAFS is an open-source implementation of the Andrew distributed file system (AFS). AFS was originally developed at Carnegie Mellon University, and developed as a commercial product by the Transarc Corporation, which was subsequently acquired by IBM. At ''LinuxWorld'' on 15 August 2000, IBM announced archived their plans to release a version of their commercial AFS product under the IBM Public License. This became OpenAFS. Today, OpenAFS is actively developed for a wide range of operating system families including: , |
Andrew File System
The Andrew File System (AFS) is a distributed file system which uses a set of trusted servers to present a homogeneous, location-transparent file name space to all the client workstations. It was developed by Carnegie Mellon University as part of the Andrew Project. Originally named "Vice", "Andrew" refers to Andrew Carnegie and Andrew W. Mellon, Andrew Mellon. Its primary use is in distributed computing. Features AFS has several benefits over traditional networked file systems, particularly in the areas of security and scalability. One enterprise AFS deployment at Morgan Stanley exceeds 25,000 clients. AFS uses Kerberos protocol, Kerberos for authentication, and implements access control lists on directories for users and groups. Each client caches files on the local filesystem for increased speed on subsequent requests for the same file. This also allows limited filesystem access in the event of a crash (computing), server crash or a network outage. AFS uses the weak cons ...

Carnegie Mellon University
Carnegie Mellon University (CMU) is a private research university in Pittsburgh, Pennsylvania, United States. The institution was established in 1900 by Andrew Carnegie as the Carnegie Technical Schools. In 1912, it became the Carnegie Institute of Technology and began granting four-year degrees. In 1967, it became Carnegie Mellon University through its merger with the Mellon Institute of Industrial Research, founded in 1913 by Andrew Mellon and Richard B. Mellon and formerly a part of the University of Pittsburgh. The university consists of seven colleges, including the College of Engineering, the School of Computer Science, and the Tepper School of Business. The university has its main campus located 5 miles (8 km) from downtown Pittsburgh. It also has over a dozen degree-granting locations in six continents, including campuses in Qatar, Silicon Valley, and Kigali, Rwanda ( Carnegie Mellon University Africa) and partnerships with universities nationally and glob ...

Jeff Eppinger
Jeffrey Lee Eppinger (born ca 1960) is an American computer scientist, entrepreneur and professor at the Carnegie Mellon University, School of Computer Science. Biography Eppinger was a student at Carnegie Mellon University, where in 1983, he won the George E. Forsythe Award for best undergraduate paper on his research in binary search trees. Eppinger had made empirical studies of their behaviour under random deletions and insertions. Eppinger earned his PhD in Computer Science in 1988. His dissertation demonstrated the integration of the Mach Operating System's virtual memory with the Camelot Transaction System. This recoverable virtual memory concept was subsequently used to implement the Coda file system. Eppinger was a co-founder of Transarc Corporation, which was acquired by IBM International Business Machines Corporation (using the trademark IBM), nicknamed Big Blue, is an American Multinational corporation, multinational technology company headquartered in Armonk ...

Distributed Computing Environment
The Distributed Computing Environment (DCE) is a software system developed in the early 1990s from the work of the Open Software Foundation (OSF), a consortium founded in 1988 that included Apollo Computer (part of Hewlett-Packard from 1989), IBM, Digital Equipment Corporation, and others. The DCE supplies a framework and a toolkit for developing client/server applications. The framework includes: * a remote procedure call (RPC) mechanism known as DCE/RPC * a naming ( directory) service * a time service * an authentication service * a distributed file system (DFS) known as DCE/DFS The DCE did not achieve commercial success. As of 1995, all major computer hardware vendors had an implementation of DCE, seen as an advantage compared to alternatives like CORBA which all had more limited support. History As part of the formation of OSF, various members contributed many of their ongoing research projects as well as their commercial products. For example, HP/Apollo contributed its Net ...
