STORAGE POWER SUPPLY SYSTEM, STORAGE DEVICE, AND CONTROL THEREOF

摘要

The present invention discloses a storage power supply system includes a first storage device coupled with a network, a second storage device coupled with the network and an uninterrupted power supply. 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 performs a self-processing corresponding to a state in which backup power is supplied when the backup state signal generated by the power supply state signal generation circuit is inputted. The second storage device performs a self-processing corresponding to a state in which backup power is supplied in response to the input of the backup state signal from the power supply state signal generation circuit to the first storage device.
