Who is the founder of Tandem Computer Company?

Tandem Computers, Inc. was the dominant manufacturer of fault-tolerant computer systems for ATM networks, banks, stock exchanges, telephone switching centers, and other similar commercial transaction processing applications requiring maximum uptime and zero data loss. The company was founded by Jimmy Treybig in 1974 in Cupertino, California.

When did Tandem Computers become part of Compaq?

Tandem computers were established in 1974 by James Treybig (“Jimmy T.”) and became a part of Compaq computers corp. in June 1997. Compaq’s NonStop Himalaya S-series servers provide 24 X 7 uptime that global infrastructure industries expect.

How is the performance of a Tandem Computer Limited?

In contrast, the performance of conventional multiprocessor systems is limited by the speed of some shared memory, bus, or switch. Adding more than 4–8 processors in that manner gives no further system speedup. NonStop systems have more often been bought to meet scaling requirements than for extreme fault tolerance.

How many stock exchanges did Tandem Computers serve?

Fifteen stock exchanges, including the New York Stock Exchange, and 30 brokerage firms worldwide used Tandem computers by mid 1986, but that market was relatively narrow and the competition was gaining. Tandem therefore broadened its product range to include workstations and mainframes.

What was the third generation of Tandem Computers?

In 1986, Tandem introduced a third generation CPU, the NonStop VLX. It had 32-bit datapaths, wider microcode, 12 MHz cycle time, and a peak rate of one instruction per microcycle. It was built from three boards of ECL gate array chips (with TTL pinout). It had a revised Dynabus with speed raised to 20 Mbytes/sec per link, 40 Mbytes/sec total.

What was the operating system of the Tandem NonStop?

The Tandem NonStop series ran a custom operating system which was significantly different from Unix or HP 3000’s MPE. It was initially called T/TOS ( Tandem Transactional Operating System) but soon named Guardian for its ability to protect all data from machine faults or software faults.
