[0031] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely.

Based on the embodiments of the present application, all other examples obtained by those of ordinary skill in the art without creative efforts are within the scope of the present application.

[0032] Currently, after the chips such as BMC and DPU of the server are connected to the ToR switch, the IP addresses of the chips such as BMC and DPU can be managed through the DHCP server connected to the ToR switch. If the number of chips to be managed is large, the corresponding IP address operation and maintenance work is also large, and more computing resources need to be allocated for the management of IP addresses, and resource occupation exists. Therefore, the present application provides a network connection scheme, only the second baseboard management controller of the network card device is configured with a dynamic IP address, the number of IP addresses to be dynamically managed is small, the corresponding IP address operation and maintenance work is small, and too many computing resources do not need to be allocated for the management of IP addresses, and efficient management of the IP addresses of the server BMC and the network card device can be achieved.

[0033] Referring to Figure 1 As shown in the figure, the embodiment of the present application discloses a network connection device, comprising: a first baseboard management controller, a switching module and at least one network card device.

[0034] That is, any one network card device comprises: one baseboard management controller and one processor, and the baseboard management controller and the processor are configured with static IP addresses in the same network segment; at the same time, the second baseboard management controller outside the network card device is also configured with a static IP address in the same network segment, and the communication between the baseboard management controller inside the network card device, the baseboard management controller outside the network card device and the processor inside the network card device can be achieved.

[0035] It should be noted that the first virtual local area network and the second virtual local area network can be implemented based on a VLAN technology. Devices and users in a VLAN (Virtual Local Area Network) are not limited by physical locations, and can be organized according to functions, departments, and applications, and the like, and communication between the devices and the users is as if they are in the same network segment. A VLAN is a broadcast domain, and communication between VLANs is completed by a Layer 3 router. Compared with a traditional local area network technology, the VLAN technology is more flexible, the management overhead of network device movement, addition, and modification is reduced, broadcast activities can be controlled, and the security of the network can be improved.

[0036] In an embodiment, the switching network comprises a DHCP server, and the DHCP server is configured to configure a dynamic IP address for the second baseboard management controller. In this embodiment, only the second baseboard management controller is configured with a dynamic IP address, and thus the number of IP addresses that need to be dynamically managed is relatively small.

[0037] In an embodiment, the switching module is arranged on a target board card, the first baseboard management controller is arranged on a server mainboard, and the target board card is plugged into the server mainboard. That is, the first baseboard management controller is located in the server.

The first virtual local area network and the second virtual local area network are isolated from each other. For example, the second network port supports a VLAN 100 untag mode, the first network port supports a VLAN 200 untag mode, and any one of the third network ports supports both the VLAN 100 untag mode and the VLAN 200 tag+ mode.

[0039] In an embodiment, the second baseboard management controller is configured with a port forwarding rule, and the second baseboard management controller is configured to forward communication data from the switching network to the first baseboard management controller according to the port forwarding rule, or to forward communication data from the first baseboard management controller to the switching network according to the port forwarding rule.

[0040] In an embodiment, the second BMC is configured to, after receiving the communication data sent by the switching network and destined to the first BMC, encapsulate the communication data with the static IP address of the first BMC as the destination address and the static IP address of the second BMC as the source address, and send the encapsulated communication data to the first BMC. In an example, the second BMC is configured to, after receiving the server management instruction sent by the switching network and destined to the first BMC, encapsulate the server management instruction with the static IP address of the first BMC as the destination address and the static IP address of the second BMC as the source address, and send the encapsulated server management instruction to the first BMC.

[0041] In an embodiment, the switching network comprises a switching device, and the second BMC is configured to, after receiving the communication data sent by the first BMC and destined to the switching device, encapsulate the communication data with the dynamic IP address of the switching device as the destination address and the dynamic IP address of the second BMC as the source address, and send the encapsulated communication data to the switching device. In an example, the second BMC is configured to, after receiving the response data of the server management instruction sent by the first BMC and destined to the switching device, encapsulate the response data with the dynamic IP address of the switching device as the destination address and the dynamic IP address of the second BMC as the source address, and send the encapsulated response data to the switching device.

[0042] In an embodiment, the second BMC is configured to, after receiving the communication data sent by the switching network and destined to the processor, send the communication data to the processor. In an embodiment, the second BMC is configured to, after receiving the communication data sent by the processor and destined to the switching network, send the communication data to the switching network.

[0043] It can be seen that the network connection device provided in the application can realize mutual communication among the first baseboard management controller, the second baseboard management controller in the network card device and the processor in the network card device by configuring the static IP addresses of the same network segment for the first baseboard management controller, the second baseboard management controller in the network card device and the processor in the network card device. Meanwhile, the switching module is provided with the first network port connected to the first baseboard management controller and divided into the first virtual local area network, the second network port connected to the switching network and divided into the second virtual local area network, and at least one third network port connected to at least one network card device and divided into the first virtual local area network and the second virtual local area network. Therefore, the switching module and any network card device can serve as a communication bridge between the first baseboard management controller and the switching network, that is, the dynamic IP address configured for the second baseboard management controller in the network card device can communicate with the switching network, and the static IP address configured for the second baseboard management controller in the network card device can communicate with the static IP address of the first baseboard management controller. Since only the second baseboard management controller is configured with a dynamic IP address, the number of IP addresses that need to be dynamically managed is small, and the IP address operation and maintenance work is less, so that too many computing resources are not needed for the management of IP addresses, and efficient management of IP addresses of the server BMC and the network card device can be realized.

[0044] Please refer to Figure 2 The GE (Gigabit Ethernet) network port of the BMC in the server is connected to one GE network port port3 of the lan switch (switching module) on the IO board, another GE network port port0 of the lan switch is connected to the ToR switch (switching device in the switching network), and the third GE network port port1 is connected to the BF3 (BlueField3, an acceleration chip). The port0 is configured to support the VLAN 100 untag mode, the port3 is configured to support the VLAN 200 untag mode, and the port1 is configured to support both the VLAN 100 untag mode and the VLAN 200 tag+ mode. Among them, only the BMC of the BF3 is exposed to the ToR switch, so that the BF3 can obtain a dynamic IP address through the DHCP network service. For this purpose, the software in the BMC of the BF3 needs to be modified to realize the function of dynamically obtaining an IP address for one network interface and configure a static IP address 192.168.1.10 for another network interface. The BF3 network card can be configured in the DPU mode and used as a DPU.

[0045] In an example, the modification of the software in the BMC to realize the function of dynamically obtaining an IP address for one network interface includes: the BMC interacts with the DHCP server to confirm the dynamic IP address of itself; and the BMC obtains the static IP address and the port forwarding rule configured by the user.

[0046] Specifically, the BMC in the server is configured with a static IP address: 192.168.1.20, the BMC in the BF3 is configured with a static IP address: 192.168.1.10, and the processor SOC (System On Chip) in the BF3 is configured with a static IP address: 192.168.1.30. The three static IP addresses are configured in the same network segment, thereby ensuring the intercommunication of the three. The port forwarding rule is configured on the BMC of the BF3, so as to redirect the BMC request of the BF3 to the BMC in the server. Specifically, the port forwarding can be performed on the 623 port of the IPMI service and the 443 port of the web service of the BMC in the server.

[0047] In the embodiment, the IO board integrated with the two-layer switch function is newly added to the mainboard of the server, the lan switch chip draws three RJ45 network ports to integrate the network connection of the BF3 and the BMC, and finally access to the ToR switch network. In addition, the port isolation is realized on the lan switch based on the vlan in the embodiment, thereby ensuring the privacy of the internal network: only the network equipment of the BF3 is exposed to the ToR switch network, thereby saving the occupation of a large amount of IP resources and facilitating the unified management of the operation and maintenance personnel.
