An I/O processor determines whether or not the amount of dirty data on a cache memory exceeds a threshold value and, if the determination is that this threshold value has been exceeded, writes a portion of the dirty data of the cache memory to a storage device. If a power source monitoring and control unit detects a voltage abnormality of the supplied power, the power monitoring and control unit maintains supply of power using power from a battery, so that a processor receives supply of power from the battery and saves the dirty data stored on the cache memory to a non-volatile memory.
