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: This application discloses a transaction processing method and a device that may be used in the field of network technologies. The method includes: A transmitting device determines a first order flag for a generated first transaction based on service logic of an application, and obtains order auxiliary information of the first transaction. The order flag indicates a dependency relationship (for example, forward dependency and backward blocking) between different transactions. This application does not depend on an operation type of a transaction. A transaction order between transactions may be set, and the receiving device ensures an execution order of each transaction based on an order flag, provided that a transaction relationship is fully expressed. The transaction order is flexibly defined, to meet the requirements of different scenarios and improve processing performance.

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.

Abstract: A stateful service processing method and apparatus are provided, related to the field of communication technologies. The method includes: preprocessing a received first packet to obtain a coalescing message of the first packet; coalescing the first packet into a first queue based on the coalescing message of the first packet, where the first queue is used to coalesce packets of a first connection to which the first packet belongs, and the first connection is a connection in which a stateful service is located; when a preset condition is met, processing, based on a context of the first connection, a plurality of packets coalesced in the first queue to obtain a second packet, where the context of the first connection is an updated context obtained after a previous second packet of the first connection is obtained; and transmitting the second packet to the host.
