Abstract: A data storage method, a computing device, and a storage system determine, from S stripes, chunks written in one batch, wherein a quantity of chunks that are in the chunks written in one batch and that belong to a same stripe is less than or equal to N, where each of the S stripes comprises (M+N) chunks, where the (M+N) chunks comprise M data chunks and N parity chunks, and where S, M, and N are positive integers, and in turn write the chunks written in one batch to M+N storage devices.

Abstract: A storage system includes a switch and a plurality of storage nodes. The switch is configured to receive a first request from a client. The first request includes an identifier of a storage partition. The switch queries an entry in a forwarding table based on the identifier to determine a target storage node in the plurality of storage nodes. The entry includes a mapping relationship between the identifier and the target storage node. The switch sends the first request to the target storage node. The target storage node is configured to receive the first request from the switch.
