US Patent 7360099 Computing environment and apparatuses with integrity based fail over

Computing units of a computing environment are equipped with means to determine their respective integrity. Further, each computing unit is equipped, such that if its integrity is determined to have been compromised, the computing unit automatically takes itself out of service. In one embodiment, prior to the automatically removing itself from service, a degree of compromise is determined. If the degree of compromise is determined to be within an acceptable risk level, the compromised computing unit fails itself over to one or more other computing units in the computing environment.
