Abstract: This application discloses a storage controller. When running, the storage controller encodes, according to a check matrix, K to-be-coded data chunks obtained from a client, to generate two check chunks. In this way, if any chunk is damaged subsequently, the damaged chunk may be recovered by using the check matrix and an undamaged chunk.

Abstract: A method describes that a lost first block in a first stripe is directly reconstructed based on a first result obtained from a target quantity of storage devices, so that there is no need to read an unlost block in the first stripe. The first block may be reconstructed provided that the target quantity of first results are obtained. An amount of data of the first result is less than that of the unlost block in the first stripe. Therefore, a data transmission process occupies less network bandwidth, and this improves block reconstruction performance.

Abstract: A data prefetching method includes a computing node obtaining information about accessing a storage node by a first application in a preset time period. The computing node determines information about prefetch data based on the access information. The computing node determines, based on the information about the prefetch data, a cache node prefetching the prefetch data, and generates a prefetch request for prefetching the prefetch data. The computing node sends the prefetch request to the cache node. The cache node performs a prefetching operation on the prefetch data in response to the prefetch request.

Abstract: An erasure code (EC)-based data processing method implemented by a storage controller includes obtaining K data chunks, dividing each of the K data chunks into two data slices, encoding the 2*K data slices based on a parity matrix including 2*M rows and 2*(K+M) columns of elements, to obtain 2*M parity slices, and separately storing the K data chunks and the M parity chunks in different storage devices.

Abstract: A method for obtaining a storage system capacity is provided. An available capacity that is of a storage system and that is associated with each stripe length is obtained based on an obtained stripe length that can be effectively configured. Therefore, an available capacity of a system is optimally selected.

Abstract: A data processing method is provided. The method includes: obtaining a parameter related to performance of a memory of a storage node, adjusting an aggregation policy based on the parameter, aggregating a first input output IO request in the memory into a second IO request based on an adjusted aggregation policy, and performing persistent storage on data corresponding to the second IO request.
