  • Patent number: 10234929
    Abstract: A first control apparatus includes a first memory unit including a local cache, a first power supply that supplies electric power to the first memory unit, and a control unit. The control unit controls a write into a memory device by a write-back method, using the local cache. The control unit mirrors data of the local cache in a mirror cache of a second control apparatus. The control unit determines whether the mirror cache is included in a second memory unit that receives electric power from a second power supply of the second control apparatus, upon detecting an abnormal state of a battery for supplying electric power to the second memory unit in case of power outage of the second power supply. The second memory unit switches write control for the memory device to a write-through method, when the second memory unit includes the mirror cache.
