DEC has flirted several times with fault-tolerant configurations of its minicomputers – the first was the original PDP-11/74 that was announced but never shipped (the number was later purloined for a single processor that became a high-end mainstay) – and the company is preparing to try again with a fault-tolerant VAX configuration. According to Electronic News, it goes by the code-name Cirrus, is a little surprisingly based on the 3.8 MIPS VAX 6300 processor, but will be a simple redundant system with just two processors, running under either VMS or Ultrix. The paper says it may be introduced in October with the Aridus CPUs.
