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.

Abstract: A data processing method in a storage system and the storage system, and relates to the field of data storage technologies. A client first sends a data block in a stripe and metadata of the data block to a data storage node. The client then sends the metadata of the data block and a parity block to a parity storage node, to back up the metadata of the data block on the parity storage node. When the metadata of the data block is successfully backed up, the data block is written into a corresponding storage device based on a storage location indicated by the metadata. This reduces write operation time.

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.
