The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Detailed ways

As shown in FIG. 1 , it is an operating environment diagram of a preferred embodiment of the method for transmitting data by a server in the present invention. The method for the server to transmit data runs on the server 1 and the baseboard management controller (baseboard management controller, BMC) 2 (hereinafter referred to as: BMC2).

The server 1 includes: an intelligent platform management interface (intelligent platform management interface, IPMI) driver 11 (hereinafter referred to as: IPMI driver 11), a basic input output system (basic input output system, BIOS) 12 (hereinafter referred to as: BIOS12) and Advanced configuration and power management interface (advanced configuration and power management interface, ACPI) driver 13 (hereinafter referred to as: ACPI driver 13).

The BMC2 includes a BMC network card 20 through which the BMC2 exchanges data with the switch 3 .

The server 1 receives the data sent by the remote network device 4, and sends the received data to the BMC2 through the IPMI driver 11, and the BMC2 uses the BMC network card 20 to transmit the data to the switch 3. When the switch 3 needs to send data to the server 1 through the BMC2, the server 1 obtains the data from the BMC2 through the BIOS 12, the ACPI driver 13 and the IPMI driver 11, and sends the data to the remote network device 4 .

As shown in FIG. 2 , it is a flow chart of a preferred embodiment of the method for transmitting data by a server in the present invention.

Step S30 , establishing a virtual network card 14 and a virtual network card driver 15 (as shown in FIG. 1 ) in the server 1 , and the virtual network card 14 communicates with the BMC2 through the IPMI driver 11 . The virtual network card driver 15 distributes a MAC (media access control) address for the virtual network card 14, and sends the MAC address of the virtual network card 14 to the BMC2 through the IPMI driver 11.

Step S31 , when the remote network device 4 sends data to the virtual network card 14 through the TCP/IP protocol, the BMC2 obtains the MAC address corresponding to the IP address according to the IP address of the virtual network card 14 . Specifically, the virtual network card 14 sends an Address Resolution Protocol (Address Resolution Protocol, ARP) request to the BMC2 through the IPMI driver 11, and the ARP request includes the IP address of the virtual network card 14. The BMC2 uses the ARP protocol to resolve the ARP request, and converts the IP address of the virtual network card 14 into a MAC address. When the BMC2 obtains the MAC address corresponding to the IP address of the virtual network card 14, the remote network device 4 can transmit the data to the BMC2.

Step S32, the virtual network card driver 15 invokes the IPMI driver 11, and the IPMI driver 11 transmits the data received by the virtual network card 14 to the BMC2.

Step S33 , the BMC2 stores the data, and transmits the data to the BMC network card 20 , and the BMC network card 20 sends the data to the switch 3 .

As shown in FIG. 3 , it is a flow chart of another preferred embodiment of the method for transmitting data by a server in the present invention.

Step S40 , when the BMC network card 20 receives the data packet sent by the switch 3 , the BMC2 judges whether the MAC address in the data packet is the MAC address of the virtual network card 14 . When the MAC address in the data packet is not the MAC address of the virtual network card 14, step S41 is performed. When the MAC address in the data packet is the MAC address of the virtual network card 14, step S42 is executed.

Step S41, the BMC2 receives the data packet and processes the data packet, and ends the process. The MAC address in the data packet is not the MAC address of the virtual network card 14, indicating that the data packet is a data packet transmitted by the switch 3 to the BMC2, and the BMC2 reads the data in the data packet.

Step S42, the BMC2 sends a system interrupt signal (system interrupt signal, SMI) to the BIOS12, and the BIOS12 generates an interrupt request (interruptrequest, IRQ) according to the SMI.

Step S43 , the ACPI driver 13 acquires the interrupt request, generates a request event (Q-event) according to the interrupt request, and sends the request event to the virtual network card driver 15 . The content of the request event is included in the request event, for example: the BMC2 receives the data packet sent by the switch 3 , and the MAC address corresponding to the data packet is the MAC address of the virtual network card 14 .

Step S44 , after the virtual network card driver 15 receives the request event, it sends a data read request to the IPMI driver 11 .

Step S45, the IPMI driver 11 accesses the BMC2, and the BMC2 transmits the data packet to the IPMI driver 11.

Step S46 , the IPMI driver 11 transmits the data packet to the virtual network card 14 .

Step S47. The virtual network card 14 transmits the received data packet to the remote network device 4 .

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be The scheme shall be modified or equivalently replaced without departing from the spirit and scope of the technical scheme of the present invention.
