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 data processing method for a network adapter includes the network adapter that obtains a first input/output (I/O) command. The first I/O command instructs to write data stored in a local server to at least one remote server, and the first I/O command includes address information and length information that are of the data and that are stored in the local server. The network adapter splits the data based on the address information and the length information to obtain a plurality of groups of address information and length information. The network adapter obtains, from the local server based on the groups of address information and length information, data corresponding to the groups of address information and length information, and sends the data to the at least one remote server.

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.
