| The VAXft 3000 was the first
fault-tolerant system in the industry to run a mainstream operating
system (VMS) and the first system in which every component, including
the backplane, was mirrored. In the event of a power failure, the
complete in-cabinet system was kept operational for up to fifteen
minutes by its own built in power supply. The VAXft 3000 development
team included (left to right) Clem O'Brien, George Hoff, Frernando
Colon Osorio, Rich Whitman and Bob Glorioso. |
