Original Abstract Submitted
After writing an access request into a first cache queue of a processor, a data processing unit (DPU) sends, in a Peripheral Component Interconnect Express (PCIe) point-to-point transmission mode, a first instruction to a storage device to which an identifier of the storage device points, where the first instruction instructs the storage device to obtain the access request from the first cache queue and execute the access request. The access request includes the identifier of the storage device to be accessed, and the storage device is connected to the processor and not directly connected to the DPU. The first instruction includes location information of the access request in the first cache queue.
