DEC VAX ft 3000 Server

Overview

The DEC 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.
