This invention provides fault tolerant capability for a Versa Module Eurocards backplane system design for high reliability applications. An approach of connecting two independent backplanes together electrically, but providing isolation capabilities in the event of a failure was developed. The electrical connection or integrated bridge design provides a virtual connection between the two VME backplanes that is transparent to the end user. The integrated virtual VMEbus design provides a low latency, high bandwidth interconnect between modules whether located on the same local bus or the electrically isolateable bus. This dual-VME fault tolerant backplane design eliminates complete system failures due to single event failures.
