Abstract: A distributed storage system comprises a data storage node Nx that receives a write success response returned by a hard disk that provides the storage address. The data storage node Nx returns a write success response to a client. The client receives the write success response returned by the data storage node Nx, and the client returns a write completion response to a host.

Abstract: A method for storing data in a distributed block storage system, where a client generates data of a stripe, and concurrently sends data of strips in the stripe to storage nodes corresponding to the strips in order to reduce data exchange between the storage nodes, and improve write concurrency, thereby improving write performance of the distributed block storage system.

Abstract: The solution discloses a data storage method in a distributed storage system: A client generates data of a stripe and concurrently sends data of strips in the stripe to storage nodes corresponding to the strips, so that data interaction between the storage nodes is reduced, and write concurrency is improved; and the storage node receives the data of the strips sent by the client and records a sequence of data of strips corresponding to a same logical address, so that write performance of a distributed block storage system is improved and data consistency is ensured.
