BRIEF DESCRIPTION OF THE DRAWINGS

[0037] With the continuous development of computer technology, servers have become an indispensable part of modern enterprises. The hardware modules inside the server are mainly composed of motherboard, processor, memory, hard disk, network card and power supply. As the server is constantly updated, the functions it supports are becoming more and more complex, so the computing performance requirements of the server are getting higher and higher. The computing performance of a single-node server has gradually failed to meet the huge computing power requirements, so dual-node servers came into being.

[0038] A traditional single-node server refers to a single node consisting of a server, which is used to host and run applications or provide specific services. A single-node server has only one motherboard inside the chassis, and all the hardware configurations inside the server are only connected to this motherboard, including the power board, network board, fan board, hard disk backplane, and expansion card slot (RISER) and other sub-card configurations. The configuration and management of a single-node server are relatively simple, low cost, and easy to deploy. Since there is only one node, the performance is relatively consistent, and there is no difference between nodes. However, a single-node server has no redundancy mechanism. Once a server fails, the entire service will be interrupted immediately, and the scalability of a single-node server will be limited. When the load increases, a single node may not be able to process all requests, and the expansion capacity is limited. In addition, the computing performance and resources of a single-node server are limited. The central processing unit (CPU), memory, and storage resources of a single node are limited, and cannot meet large-scale needs. The development of dual-node servers effectively solves various problems of single-node servers.

[0039] A dual-node server usually refers to a cluster system consisting of two server nodes. A dual-node server has two mainboards inside the chassis, and the two mainboards are the corresponding two nodes. Inside the dual-node server, each node has its own hardware configuration and common hardware modules. For example, the power board inside the dual-node server can power both node 0 and node 1, so that one power board can meet the power supply requirements of the two nodes inside the dual-node server, greatly saving the space inside the server. In addition to the power supply requirements, the network connection problem of the dual-node server also needs to be paid attention to. The network connection problem of the single-node server can be solved through the network pass-through board. The Slimline connector on the network pass-through board is connected to the Slimline connector on the mainboard through a cable, and then the network cable is connected to the RJ45 connector of the network pass-through board to achieve the network connection of the single-node server. This network pass-through board is suitable for single-node servers. If the network pass-through board is applied to a dual-node server, each node needs a network pass-through board. The dual-node server needs two identical network pass-through boards to ensure normal network connection. Although this network connection method can achieve normal connection between two node networks, it will occupy more chassis front window space resources and network port resources.

[0040] See Figure 1, which is a schematic diagram of the structure of a network pass-through board. The composition of the network pass-through board is very simple, mainly consisting of an RJ45 connector, a Slimline connector and a chip on the board. The chips on the network pass-through board mainly include a temperature sensor and a memory. The temperature sensor is mainly used to monitor the temperature of the network pass-through board, and the memory is mainly used to store relevant information of the network pass-through board.

[0041] See Figure 2, which is a network connection topology diagram of a single-node server in the related art. As can be seen from the figure, the Slimline connector on the mainboard side and the Slimline connector on the network pass-through board side are connected by a cable, so that the mainboard and the network pass-through board are connected. The network signal (MDI) between the physical layer interface (PHY) chip on the mainboard and the RJ45 connector on the network pass-through board is directly connected, and electrostatic protection (ESD) and other devices can also be connected in the middle to ensure the quality of the network signal. The line activation (LINK_ACT) signal and the lighting signal (such as the 100M / 1000M lighting signal) are both controlled by the physical layer interface chip on the mainboard. When the RJ45 connector on the network pass-through board is connected to an external network port or switch through a network cable, the network port light on the RJ45 connector will indicate the status of the network connection under the control of the physical layer interface chip.

[0042] When the network port light is on normally, it means that the network connection function of the single-node server is normal. From the above figure, you can intuitively feel that this network connection method is very suitable for single-node servers. The principle is very simple and the implementation of network connection is very convenient. It not only ensures the convenience of single-node server network connection, but also ensures the stability of single-node server network connection.

[0043] In the actual server field, dual-node servers are becoming more and more common. Both nodes in a dual-node server need network connection, but a network pass-through board can only realize the network connection function of one node. Obviously, there are certain disadvantages in using a network pass-through board in a dual-node server.

[0044] See Figure 3, which is a network connection topology diagram of a dual-node server in the related art. As can be seen from the figure, if a network pass-through board is used to realize the network connection of the dual-node server, both node 0 and node 1 (i.e., motherboard 0 and motherboard 1) need to be connected to a separate network pass-through board, and each network pass-through board also needs a separate network cable to be connected to a different RJ45 connector. Although this method can realize the network connection function of the two nodes of the dual-node server, the use of two network pass-through boards not only makes the space inside the dual-node server chassis more tight, but the two RJ45 connectors will also occupy more space on the front window of the server, wasting network port resources.

[0045] To this end, the LAN switch board provided in this application saves the internal space and external network port resources of the dual-node server.

[0057] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] Referring to FIG. 4 , FIG. 4 is a schematic diagram of the structure of a local area network switch board according to an embodiment of the present invention. The local area network switch board may include:

[0059] The LAN switching chip 1 is used to parse the received node mode control instruction to obtain the target node mode to be controlled; load the target firmware from the firmware memory 2 according to the target node mode; receive the network signal sent by the RJ45 connector 4; configure the network signal pin according to the target firmware, and send the network signal to the first Slimline connector 3; wherein the target node mode is any one of the single node mode and the dual node mode; the target firmware is any one of the single node firmware and the dual node firmware;

[0060] Firmware storage 2, used for obtaining target firmware corresponding to the target node mode and storing the target firmware;

[0061] RJ45 connector 4, used to receive network signals from external network devices and send the network signals to the LAN switch chip 1;

[0062] The first Slimline connector 3 is used to forward the network signal to the second Slimline connector in the first node and / or the third Slimline connector in the second node according to the network signal pin configuration.

[0063] The LAN switch board (LAN SWITCH) provided in an embodiment of the present invention may include a LAN switch chip 1, a firmware memory 2, a firmware memory 2 and an RJ45 connector 4. The baseboard management control in the node sends a node mode control instruction to the LAN switch chip 1, and the LAN switch chip 1 parses the received node mode control instruction to obtain the target node mode to be controlled, and the target node mode is a single node mode or a dual node mode. The firmware memory 2 pre-acquires the target firmware corresponding to the target node mode and stores the target firmware, and the target firmware is a single node firmware or a dual node firmware. The LAN switch chip 1 loads the target firmware (Firmware, FW) from the firmware memory 2 according to the target node mode. The RJ45 connector 4 receives the network signal of the external network device and sends the network signal to the LAN switch chip 1. The LAN switch chip 1 receives the network signal sent by the RJ45 connector 4, configures the network signal pin according to the loaded target firmware, and sends the network signal to the first Slimline connector 3.

[0064] It can be seen from the above technical solution that by setting the LAN switch chip to configure the network signal pins according to the target node mode to be controlled, the network signal pins are configured according to the loaded target firmware, and the network signal is sent to the first Slimline connector. The first Slimline connector selects the corresponding Slimline connector from the second Slimline connector in the first node and the third Slimline connector in the second node according to the network signal pin configuration to forward the network signal. Thus, adaptive switching of the network connection of the single-node server and the network connection of the dual-node server is realized, the single-node and dual-node network board multiplexing is realized, the internal space of the dual-node server is saved, and a LAN switch chip is used to provide network connection functions for two nodes. The LAN switch chip is suitable for both single-node application scenarios and dual-node application scenarios, saving the internal space of the dual-node server and external network port resources.

[0065] It should be noted that, based on the above embodiment, the embodiment of the present invention also provides corresponding improved solutions. In the subsequent embodiments, the same steps or corresponding steps as those in the above embodiment can be referenced to each other, and the corresponding beneficial effects can also be referenced to each other, which will not be repeated one by one in the following improved embodiments.

[0066] In a specific embodiment of the present invention, it also includes:

[0067] The first temperature sensor chip 5 is used to monitor the temperature information of the LAN switch board; when receiving a temperature information reading request sent by the first node, the temperature information is transmitted to the first node;

[0068] The second temperature sensor chip 6 is used to monitor the temperature information of the LAN switch board; when receiving a temperature information reading request sent by the second node, the temperature information is transmitted to the second node.

[0069] The LAN switch board provided in the embodiment of the present invention may also include a first temperature sensor chip 5 and a second temperature sensor chip 6, both of which are used to monitor the temperature information of the LAN switch board. When the first node needs to read the temperature information of the LAN switch board, a temperature information reading request is sent to the first temperature sensor chip 5. When the first temperature sensor chip 5 receives the temperature information reading request sent by the first node, the temperature information is transmitted to the first node. When the second node needs to read the temperature information of the LAN switch board, a temperature information reading request is sent to the second temperature sensor chip 6. When the second temperature sensor chip 6 receives the temperature information reading request sent by the second node, the temperature information is transmitted to the second node. By setting a first temperature sensor chip 5 for the first node to monitor the temperature information of the LAN switch board, and setting a second temperature sensor chip 6 for the second node to monitor the temperature information of the LAN switch board, the first node and the second node can both obtain the temperature information on the LAN switch board. This ensures that even if one node hangs, the other node can still monitor the temperature on the LAN switch board, avoiding conflicts in the acquisition of temperature information by the two nodes, achieving effective monitoring of the temperature information of the LAN switch board, and improving the reliability of the system.

[0070] In a specific implementation of the present invention, the local area network switch board may further include:

[0071] The first storage chip 7 is used to store the board information of the LAN switch board; when receiving the board information reading request sent by the first node, the board information is transmitted to the first node;

[0072] The second storage chip 8 is used to store the board information; when receiving the board information reading request sent by the second node, the board information is transmitted to the second node.

[0073] The LAN switch board provided in the embodiment of the present invention may also include a first storage chip 7 and a second storage chip 8, and the first storage chip 7 and the second storage chip 8 both store the board information of the LAN switch board. When the first node needs to read the board information of the LAN switch board, a board information reading request is sent to the LAN switch board. When the LAN switch board receives the board information reading request sent by the first node, the board information is transmitted to the first node. When the second node needs to read the board information of the LAN switch board, a board information reading request is sent to the LAN switch board. When the LAN switch board receives the board information reading request sent by the second node, the board information is transmitted to the second node. Thereby, the effective storage of the board information of the LAN switch board is realized, the conflict of the two nodes in obtaining the board information is avoided, and it is convenient for users to randomly call and display the board information.

[0074] The first storage chip 7 and the second storage chip 8 are mainly used to store the manufacturer of the LAN switch board, the board production date, the board printed circuit board assembly (PCBA) version, the manufacturer side board product number (PN) and the manufacturer side board serial number (SN) and other information. By using the first storage chip 7 and the second storage chip 8 to store the board information of the LAN switch board respectively, it is ensured that both nodes in the dual-node server can obtain the board information of the storage LAN switch board. For example, the two nodes can obtain the board information of the storage LAN switch board through the integrated circuit bus (Inter-Integrated Circuit, I2C), thereby making full use of the advantages of the integrated circuit bus such as simplicity, ease of use, high flexibility, and strong scalability.

[0075] In a specific implementation of the present invention, the firmware memory 2, the first storage chip 7 and the second storage chip 8 are all erasable programmable read-only memories.

[0076] The firmware memory 2, the first storage chip 7 and the second storage chip 8 are all electrically erasable programmable read-only memories (EEPROM). By making the firmware memory 2, the first storage chip 7 and the second storage chip 8 all erasable programmable read-only memories, the advantages of the erasable programmable read-only memories such as programmability, erasability, long-term data retention, random accessibility, low power consumption, high reliability and good flexibility are fully utilized.

[0077] In a specific implementation of the present invention, the LAN switch chip 1 is specifically configured to send a network signal to the first Slimline connector 3 via a first network signal pin corresponding to the first node and / or a second network signal pin corresponding to the second node.

[0078] The LAN switch chip 1 includes a plurality of network signal pins. When it is determined that the current node mode is a single node mode, if the node to be currently connected to the network is the first node, the LAN switch chip 1 sends the network signal to the first Slimline connector 3 through the first network signal pin corresponding to the first node. When it is determined that the current node mode is a single node mode, if the node to be currently connected to the network is the second node, the LAN switch chip 1 sends the network signal to the first Slimline connector 3 through the second network signal pin corresponding to the second node. When it is determined that the current node mode is a dual-node mode, the LAN switch chip 1 sends the network signal to the first Slimline connector 3 through the first network signal pin corresponding to the first node, and sends the network signal to the first Slimline connector 3 through the second network signal pin corresponding to the second node. Thus, the network expansion function of the LAN switch chip 1 is fully utilized, thereby realizing the function of providing network connection for two mainboards in the dual-node server at the same time.

[0079] In a specific implementation of the present invention, the local area network switch board may further include:

[0080] The multiplexer is used for, when receiving a firmware upgrade link switching instruction, switching the link to connect the firmware memory 2 to the first Slimline connector 3, so as to perform firmware upgrade through the link between the first Slimline connector 3 and the firmware memory 2; when receiving a firmware loading link switching instruction, switching the link to connect the firmware memory 2 to the local area network switch chip 1, so as to perform firmware loading through the link between the local area network switch chip 1 and the firmware memory 2.

[0081] See Figure 5, which is a network connection topology diagram of a single-node server in an embodiment of the present invention. See Figure 6, which is a network connection topology diagram of a dual-node server in an embodiment of the present invention. The LAN switch board provided in the embodiment of the present invention may also include a multiplexer (Multiplexer, MUX). When the multiplexer receives a firmware upgrade link switching instruction, it switches the link to the firmware memory 2 connected to the first Slimline connector 3, such as by controlling the strobe pin (SEL PIN) of the multiplexer to select the first Slimline connector 3, so that the firmware is upgraded through the link between the first Slimline connector 3 and the firmware memory 2. When the firmware loading link switching instruction is received, the link is switched to the firmware memory 2 connected to the LAN switch chip 1, such as by controlling the strobe pin of the multiplexer to select the LAN switch chip 1, so that the firmware is loaded through the link between the LAN switch chip 1 and the firmware memory 2. Fast switching of firmware upgrade and firmware loading is achieved through the multiplexer.

[0082] In a specific implementation of the present invention, the local area network switch chip 1 is a 88E6141 chip.

[0083] The LAN switching chip 1 provided in the embodiment of the present invention can be set as an 88E6141 chip, and its chip pins can be connected to four groups of network signals. A group of network signals accessed externally through the RJ45 connector 4 can be expanded into two or three groups of network signals through the 88E6141 chip, thereby making full use of the advantages of the 88E6141 chip, such as high integration, high performance, high security, power saving, strong compatibility, and high reliability.

[0084] It should be noted that, in addition to the 88E6141 chip, the LAN switch chip 1 can also be set to other chips with network signal expansion functions, such as the RTL8367SC chip. The RTL8367SC chip can receive 5 groups of network signals. The selection of the LAN switch chip 1 can be selected according to the demand for the number of extended resources of the network resources, and the embodiment of the present invention does not limit this.

[0085] Corresponding to the above LAN switch board embodiment, the present invention further provides a network management method. The network management method described below and the LAN switch board described above can be referenced to each other.

[0086] Referring to FIG. 7 , FIG. 7 is a flowchart of an implementation of a network management method in an embodiment of the present invention. The method may include the following steps:

[0087] S701: Parse the received node mode control instruction to obtain the target node mode to be controlled.

[0088] The target node mode is any one of a single node mode and a dual node mode;

[0089] S702: Load target firmware from the firmware memory according to the target node mode.

[0090] The target firmware is any one of single-node firmware and dual-node firmware.

[0091] S703: Receive the network signal sent by the RJ45 connector.

[0092] S704: Perform network signal pin configuration according to the target firmware, and send the network signal to the first Slimline connector, so that the first Slimline connector forwards the network signal to the second Slimline connector in the first node and / or the third Slimline connector in the second node according to the network signal pin configuration.

[0093] It can be seen from the above technical solution that by setting the LAN switch chip to configure the network signal pins according to the target node mode to be controlled, the network signal pins are configured according to the loaded target firmware, and the network signal is sent to the first Slimline connector. The first Slimline connector selects the corresponding Slimline connector from the second Slimline connector in the first node and the third Slimline connector in the second node according to the network signal pin configuration to forward the network signal. Thus, adaptive switching of the network connection of the single-node server and the network connection of the dual-node server is realized, the single-node and dual-node network board multiplexing is realized, the internal space of the dual-node server is saved, and a LAN switch chip is used to provide network connection functions for two nodes. The LAN switch chip is suitable for both single-node application scenarios and dual-node application scenarios, saving the internal space of the dual-node server and external network port resources.

[0094] In a specific embodiment of the present invention, sending the network signal to the first Slimline connector may include the following steps:

[0095] The network signal is sent to the first Slimline connector via the first network signal pin corresponding to the first node and / or the second network signal pin corresponding to the second node.

[0096] Corresponding to the above LAN switch board embodiment, the present invention further provides a network management device. The network management device described below and the LAN switch board described above can refer to each other.
