  • Patent number: 5560033
    Abstract: A highly available processor complex that can use industry standard hardware and software through use of an N+K sparing arrangement with a separate monitor ("watchdog") processor. The watchdog processor monitors periodic "heartbeat" messages from the monitored elements and can change activity and status of such monitored elements through control messages. Further, the watchdog processor is operatively connected to a power control circuit that controls the power to the monitored elements. Thus, the watchdog processor can guarantee that a faulty element can be rendered non-functional and can also totally restart an element through power cycling it.
