DISTRIBUTED STORAGE SYSTEM AND DATA READ-WRITE METHOD THEREFOR, AND STORAGE TERMINAL AND STORAGE MEDIUM

摘要

Disclosed are a distributed storage system and a data read-write method therefor, and a storage terminal and a storage medium. The data read-write method for the distributed storage system comprises: a client generating multiple data read requests, wherein the multiple data read requests comprise a first data read request and a second data read request (S301); the client sending the first data read request to a first storage node and sending the second data read request to a read request coordination module (S302); the first storage node acquiring the first data read request and acquiring first data from stored data according to the first data read request; and the read request coordination module acquiring the second data read request and acquiring second data from data stored in a second storage node according to the second data read request (S303); the first storage node sending the first data to the client; and the read request coordination module sending the second data to the client (S304). In this way, a read expansion capability of the distributed storage system can be improved.
