Abstract
A multiprocessor system the kind in which two or more separate processor modules are interconnected for parallel processing. The multiprocessor system includes an input/output system having multi-port device controllers and input/output buses connecting each device controller for access by the input/output channels of at least two different processor modules. The multiprocessor system includes a distributed power supply system which insures non-stop operation of the remainder of the multiprocessor system in the event of a failure of a power supply for a part of the system. The distributed power supply system includes a separate power supply for each processor module and two separate power supplies for each device controller. A power interlock system and a method are provided for protection against data corruption.
