Embodiments of this application disclose a data processing apparatus and method, and a related device. Storage space of a second device is mapped to a memory-mapped input/output MMIO address space of the first device. N MMIO addresses in the MMIO address space of the first device are in a one-to-one correspondence with N first storage addresses in the storage space of the second device. The processor is configured to send a first instruction to the storage controller, where the first instruction includes a target MMIO address. The storage controller is configured to: receive the first instruction, and determine a first storage address corresponding to the target MMIO address; and send a first operation instruction to the second device, where the first operation instruction corresponds to the first instruction, and the first operation instruction includes the first storage address.
