US Patent 7337373 Determining the source of failure in a peripheral bus

Many computing system environments require continuous availability and high operational readiness. The ability to find, diagnose, and correct actual faults and potential faults in these systems is a high priority. By combining a continually updated database of computing system performance with the ability to analyze that information to detect faults and then communicating that fault information to correct the fault or provide appropriate notification of the fault results in achieving the goals of high availability and operational readiness. FIG. (1) shows how the data collectors, fault detectors and policy actions are combined to meet those goals.
