Veritas Software Corp. was an international software company that was founded in 1983 as Tolerant Systems, renamed Veritas Software Corp. in 1989, and merged with Symantec in 2005. It was headquartered in Mountain View, California. The company specialized in storage management software including the first commercial journaling file system, VxFS, VxVM, VCS, the personal/small office backup software Backup Exec and the popular enterprise backup software NetBackup. Veritas was listed on the S&P 500 and the NASDAQ-100 under the VRTS ticker symbol.
[edit] OriginTolerant Systems was a company founded in 1983 by Eli Alon and Dale Shipley (both from Intel) to build fault-tolerant computer systems based on the idea of "shoe-box" building blocks. Tolerant initially based their shoe-box system on the 32016 microprocessor from National Semiconductor, and then upgraded the systems to the 32032 when those processors, with a 32-bit data bus, became available. The shoe-box consisted of a OS processor, running a version of Unix called TX, and on which applications ran, and an I/O processor, running a Real Time Executive developed by Tolerant called RTE; both processors were 320xx processors. The system was marketed as the "Eternity Series." Each shoe-box had two Ethernet connectors which allowed a fault-tolerant connection to other shoe-box systems. Further, a proprietary I/O system was created that ran at 3 Mbyte/second up to 15 m (50 feet) allowing up to 16 peripherals per I/O. Tolerant developed a custom Disk Controller, Communications Interface Processor (CIP), and Tape Controller that communicated on this I/O bus. The CIP was a front-end for 12 or 16 serial ports also based on the National 32016 processor and executing RTE. The CIP could host forms software, or other pre-processing applications to allow intelligent use of the terminals that were attached. This lightened the interrupt overhead to the OS processor. One example was customization of the vi text editor where the CIP hosted a small part of the application allowing for local character echoing while in insert mode. The software gained a level of fault-tolerance through check-pointing technology. Applications needed to be fortified with this check-pointing to allow roll-back of the application on another processor if a hardware failure occurred. Tolerant also developed a forerunner of today's RAID systems by incorporating a journaling file system and multiple copies or N-plexing the disk drive content. The company got out of the hardware business in 1989 and became Veritas Software by using this earlier work in journaled file systems as the basis for a new line of products for Windows NT and Unix systems.

[edit] Merger with SymantecOn December 16, 2004, Veritas and Symantec announced their plans for a merger in a deal valued at $13.5 billion. It was the largest announced software industry merger to date. On June 24, 2005, Veritas and Symantec shareholders voted to approve the merger. On July 2, 2005, Symantec and Veritas finalized the merger and the resulting company has retained the name Symantec.
