Abstract:
1. A storage power supply system, comprising: a first storage device coupled with a network; a second storage device coupled with the network; and an uninterrupted power supply that supplies power to the first storage device and the second storage device; the uninterrupted power supply comprises a backup circuit that supplies backup power when commercial power supply is interrupted; the uninterrupted power supply comprises a power supply state signal generation circuit that generates a power supply state signal indicating a state of the power; the power supply state signal includes a backup state signal indicating a supply of backup power; the first storage device is coupled with the power supply state signal generation circuit; the first storage device outputs information corresponding to the supply of backup power to the second storage device when the backup state signal generated by the power supply state signal generation circuit is inputted; the second storage device outputs to the first storage device processing start information that indicates the start of a processing corresponding to the state in which backup power is supplied and performs a self-processing corresponding to a state in which backup power is supplied when the information corresponding to the supply of backup power is inputted from the first storage device; and the first storage device causes the uninterrupted power supply to stop the supply of backup power after a self-processing corresponding to the state in which backup power is supplied has been performed when the processing start information is inputted from the second storage device, while performs a self-processing corresponding to the state in which backup power is supplied without causing the supply of backup power to stop to the uninterrupted power supply when the processing start information is not inputted from the second storage device.
