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.

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 method is implemented by a system on chip and includes: receiving a volume attaching request sent by the public cloud management component, where the volume attaching request includes an identifier of a system volume; and storing the identifier of the system volume based on the volume attaching request, where when the bare-metal server is started, the bare-metal server uses the identifier of the system volume to determine the system volume, and starts an operating system of the bare-metal server based on the system volume, and the system volume stores a file used for starting the operating system of the bare-metal server.
