An SPOF is a component in the system which if it fails, will cause the entire system to fail. In the FineArtOfConfiguringaCluster[1], one normally works to design out all SPOFs, through the use of redundancy[2]. When all SPOFs have been eliminated, then one is only left with the much less likely event of a MultipleSimultaneousFailure[3].
