<p>Disclosed are a power failure processing method and system for a storage system. The storage system comprises a primary power source, a backup power source, a first controller, a second controller, and a storage device, the first controller comprising a first buffer, and the second controller comprising a second buffer. The method comprises: when the primary power source is powered off, the first controller executing an operation of writing data of the first buffer into the storage device by using the backup power source, and the second controller executing an operation of writing data of the second buffer into the storage device by using the backup power source; when all data of the first buffer has been written into the storage device but data of the second buffer has not all been written into the storage device, the first controller sending a first turn-off signal to the backup power source, so that the first controller implements a power-off operation; and when the primary power source restores power supply, the first controller initiating a power-on operation by using the primary power source. Also disclosed is a storage system. The method can improve a restoration capability and reliability of a storage system.</p> |
