The invention provides a remote direct data access implementation method and device, an adapter and a storage medium, and relates to the technical field of computers, in particular to the technical field of data transmission. According to the specific implementation scheme, sending WQEs in a plurality of sending queues in a request end host are scheduled to a plurality of sending prefetching queues; scheduling the sending WQEs in the plurality of sending prefetching queues to at least one end-to-end shared sending queue; according to the shared sending context corresponding to each end-to-end shared sending queue, the sending WQE in each end-to-end shared sending queue is processed in sequence to form a sending message, and the sending message is sent to a response end matched with the opposite end address identifier in the sending message. According to the technical scheme provided by the embodiment of the invention, a specific implementation mode of the RDMA based on the shared queue architecture is provide
