With its present OEM supplier Sequoia Systems Inc still stuck on the 68040 processor, it looks as if Hewlett-Packard Co’s fault-tolerant Unix future lies with machines from Stratus Computer Inc, even if gossip that Hewlett wants to buy the Marlborough, Massachusetts-based systems builder proves unfounded. At all events, Stratus yesterday announced that it will license the HP-UX implementation of Unix and put it up on the Continuum family of Precision Architecture RISC-based fault-tolerant computers. The move will enable business-critical applications that currently run under HP-UX to run unchanged on Stratus’s fault-tolerant Continuum systems. Stratus will also resell a range of key HP-UX layered software products on Continuum. Stratus plans to release HP-UX on the Continuum Series 400 at the end of 1996, with availability on other Continuum models next year.
