Abstract: A storage array includes a plurality of hard disks, where each of the hard disks is divided into a plurality of chunks, and a plurality of chunks of different hard disks form a chunk group using a redundancy algorithm. The storage array obtains fault information of a faulty area in a first hard disk, and determines a faulty chunk storing the lost data according to the fault information. The storage array recovers the data in the faulty chunk using another chunk in a chunk group to which the faulty chunk belongs and stores the recovered data in a recovered chunk. The recovered chunk is located in a second hard disk which is not a hard disk for forming the chunk group.

Abstract: Embodiments of the present disclosure provide a data processing method, a controller, a storage device, and a storage system. The controller adds an execution time of an IO request to the IO request, and the execution time is used to instruct the storage device to complete the IO request before the execution time expires. The controller sends, to the storage device, the IO request to which the execution time is added. When receiving the IO request, the storage device can execute the IO request based on the execution time of the IO request.
