STORAGE POWER-SUPPLY FEEDING SYSTEM, STORAGE DEVICE, ITS CONTROL METHOD AND CONTROL PROGRAM

摘要

PPROBLEM TO BE SOLVED: To make a storage device perform processing adapted to the state in which backup power is fed at the interruption of a commercial power supply, even if the storage device cannot directly know the state in which the backup power is fed from an uninterruptive power supply device. PSOLUTION: The first and the second storage devices 200, 300 connected to a network N1 are fed with power from at least the uninterruptive power device 100, the first storage device 200 performs the processing adapted to the state in which the backup power is fed to itself when inputted with a signal of the state in which the supply of the backup power generated by a power-supply signal generation circuit 162 of the uninterruptive power supply device is indicated, and the second storage device 300 performs the processing adapted to the state in which the backup power is fed to itself according to the input of the signal of the state in which the supply of the backup power to the first storage device 200 from the power-supply state signal generation circuit 162 is indicated.
