    Abstract: A disk subsystem and a data restoration method with which the rise time when the disk subsystem is restored can be shortened.A disk subsystem and data restoration method whereby, when the power of the disk subsystem is shut off, the shared memory management table is saved to non-volatile memory together with the cache data and, when the power of the disk subsystem is restored, the shared memory management table is referenced and the duplex data is assigned by two non-volatile memories and restored to each of two shared memories.

    Abstract: 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.
