Abstract:
A method for managing redundancy computer based systems having multiple hardware computing nodes comprising the steps of:providing a corresponding redundancy management system (RMS) to each computing node:establishing a communication link between each RMS:implementing a fault tolerant executive (FTE) module in each RMS for managing faults and a plurality of system functions;defining each computing node as a fault containment region;detecting faults/errors in data generated in a computing node, said detecting comprising the step of voting on data generated by each node to determine whether data generated by one node is different from a voted majority; andisolating a detected fault within the fault containment region to prevent propagation into another computing node, said isolating comprising using the step of voting on data as an output to mask a fault when data generated by a particular node is different from the voted majority.
