The Evolution of Fault-Tolerant Computing
Tandem builds single-fault-tolerant computer systems. At the hardware level, the system is designed as a loosely coupled multi-processor with fail-fast modules connected via dual paths. It is designed for online diagnosis and maintenance. A range of CPUs may be inter-connected via a hierarchical fault-tolerant local network. A variety of peripherals needed for online transaction processing are attached via dual ported controllers.
