STORAGE POWER SUPPLY SYSTEM, STORAGE DEVICE, AND CONTROL THEREOF
First Claim
1. A storage power supply system, comprising:
- a first storage device coupled with a network;
a second storage device coupled with the network;
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 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; and
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.

Abstract
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.
