Abstract: A data processing method is provided. The method is implemented in a distributed storage system including at least two storage disk clusters. The at least two storage disk clusters are configured with at least two energy saving states. The method includes: receiving, by a processing module of the distributed storage system, a read request including an identifier of to-be-processed data; reading metadata of the to-be-processed data based on the identifier of the to-be-processed data, to determine a first storage disk cluster and a second storage disk cluster, where the first storage disk cluster and the second storage disk cluster are configured with different energy saving states; and reading first sub-data from the first storage disk cluster, and after the first sub-data is read, reading second sub-data from the second storage disk cluster.

Abstract: A solution for processing a stripe in a storage device is provided. Where at least one stripe unit not requiring garbage collection from each stripe of at least two stripes in the storage device is determined, each of the at least two stripes comprises a stripe unit requiring garbage collection and a stripe unit not requiring garbage collection; parity data of data in the determined stripe units not requiring garbage collection is computed and stored into a first idle stripe unit, where the first idle stripe unit and the determined stripe units not requiring garbage collection are in a new stripe in the storage device.
