Abstract: In an NVMe-based storage system, a host is connected to an NVMe controller through a PCIe bus, and the NVMe controller is connected to a storage medium. The NVMe controller receives from the host a data packet that carries payload data and an association identifier. The association identifier associates the payload data with a write instruction. The NVMe controller obtains the write instruction according to the association identifier, and then writes the payload data into the storage medium according to the write instruction.

Abstract: A non-volatile memory express (NVMe)-based data read method, apparatus, and system are provided. In various embodiments, a read instruction can be triggered by a host. The read instruction carries indication information of a first address opened by the host to an NVMe controller for addressing and accessing. In those embodiments, the host after obtaining the read instruction can send a data packet to the host. The data packet carries the first address and payload data. Still in those embodiments, the host can, after receiving the data packet, determine a second address based on the first address, and store the payload data into storage space indicated by the second address. The second address may be a private memory address of the host. Because a relationship between the second address and a communication protocol is broken, and the host may access the second address without being restricted by the communication protocol.
