Data access method, device and storage medium

Abstract

This application provides a data access method, apparatus, and storage medium, comprising: a storage node receiving a Remote Direct Data Access (RDMA) connection request sent by a computing node, the RDMA connection request carrying a target solid-state drive (SSD) identifier, the RDMA connection request being used to instruct the storage node to establish an access connection between the computing node and the target SSD; the storage node acquiring and storing connection establishment information corresponding to the access connection, wherein the connection establishment information includes a completion queue (CQ); the storage node sending a first address corresponding to the stored connection establishment information to the target SSD to instruct the target SSD to acquire the CQ in the connection establishment information and listen to the CQ. Using this application embodiment can effectively improve data access efficiency. Simultaneously, it reduces the CPU / memory overhead of the storage node, effectively eliminating system bottlenecks.
