    Abstract: A data read/write method includes: establishing a first connection to a client, determining a first tablespace corresponding to the first connection, and determining a first node corresponding to the first connection or the first tablespace in a plurality of nodes, where the first connection receives a read/write request from the client; loading data in the first tablespace to a memory in the first node, and processing a read/write request on the first connection using a first working thread, where the first working thread is generated by a processor in the first node.

    Abstract: A data forwarding chip and a server are disclosed. The server includes a data forwarding chip, a network interface card, and a processor. The data forwarding chip is separately connected to the network interface card and the processor through a bus. After receiving a data forwarding request sent by the processor or the network interface card, the data forwarding chip forwards, based on a destination address of the data forwarding request through an endpoint port that is on the forwarding chip and that is directly connected to a memory space corresponding to the destination address of the data forwarding request, to-be-forwarded data specified in the data forwarding request, such that when the server sends or receives data, cross-chip transmission of data between processors occurs, thereby reducing a data transmission delay.

    Abstract: A data processing method includes receiving, by a virtual machine, an I/O access request. The I/O access request is used to access data, the I/O access request includes a type of hardware data used to indicate a working status of a virtual I/O device, and the virtual I/O device is obtained after the I/O device is virtualized. The method also includes identifying, by the virtual machine, that the type of the hardware data in the I/O access request is first-type data. The first-type data is hardware data of the virtual I/O device that remains unchanged in a data processing process. The method further includes obtaining, by the virtual machine, to-be-accessed data from a first memory space. The first memory space is memory storage space in the data processing system.

    Abstract: A data processing method, including: obtaining, by a device in a server, a first I/O request sent by a virtual machine, where the device is connected to the server through a PCIe bus, the virtual machine runs on the server, the device provides a plurality of VFs for the server, the first I/O request is initiated by the virtual machine for any one VF of the plurality of VFs, the first I/O request includes a read operation or a write operation, the read operation is used to perform a data read operation on an I/O device in the server, the write operation is used to perform a data write operation on the I/O device in the server; and reading or writing, by the device, data from or into the I/O device in the server based on the first I/O request.
