Abstract: In a method for accessing a storage system, a client in the storage system identifies a logical address of a storage device, and queries a management server regarding a mapping between the storage device and a start address of a submission queue (SQ) in the memory of the storage node. The client then sends an access request including the logical address of the storage device directed to the start address of the SQ to a network interface card NIC of the storage node. The NIC receives and sends the access request to the start address of the SQ in the memory. The storage device obtains the access request from the start address of the SQ and executes the access request.
