Abstract
A controller capable of self-monitoring, a redundant storage system having the same, and its method are proposed. Each controller is arranged with a self-monitoring operating circuit and a watchdog unit. The self-monitoring operating circuit can periodically issue a confirmation signal to the watchdog unit. The watchdog unit comprises a counter unit for counting a predetermined time interval, and if it does not receive the confirmation signal issued by the self-monitoring operating circuit over the predetermined time interval, it will send out an output signal to the self-monitoring operating circuit. The self-monitoring operating circuit will then generate a plurality of global reset signals to shut down the entire operation of the controller. Another controller will take over the functions of the shut-down controller.
