Description

[0001] This application is a divisional application of the invention patent application with application number CN202211606308.1 submitted to the China Patent Office, application date December 12, 2022, and invention name “A network interface control method and multi-node server”. Technical Field

[0002] The present application relates to the field of server technology, and in particular to a network interface control method and a multi-node server. Background Art

[0003] A multi-node server is a server with multiple nodes. A node is also called a node server. The function of a node is equivalent to that of a single-node server. Therefore, a multi-node server can be understood as multiple servers deployed in one space.

[0004] Currently, among the multiple nodes of a multi-node server, one node is usually designated as a management board, which is used to connect to the network interface to access the network cable. Users can access the baseboard management controller (BMC) of each node in the multi-node server through the management board, that is, the management board can be used as a switch for each node in the multi-node server. However, if the node is used exclusively as a management board, the cost is high and the performance of the node is not fully utilized. Summary of the invention

[0005] The embodiments of the present application provide a network interface control method and a multi-node server, which are used to control the network interface of the multi-node server to solve the problem of network loopback.

[0006] The first aspect of the present application provides a method for controlling a network interface, which is applied to a multi-node server, wherein the multi-node server includes a switching chip module, at least M nodes, and at least M network interfaces, wherein the M nodes correspond to the M network interfaces in a one-to-one manner, and the switching chip module includes N ports, wherein M and N are both integers greater than or equal to 2, and N is greater than M. Among them, the M nodes are connected to M ports of the N ports in a one-to-one manner, and P ports of the N ports that are not connected to the M nodes are connected to P network interfaces of the M network interfaces in a one-to-one manner, and the M network interfaces are used to access network cables, and P is a positive integer less than or equal to M.

[0007] It can be seen that, since at least one of the P network interfaces is connected to a network cable, the network cable can be connected to a switch / router, and the M nodes in the multi-node server can send a first data message to the switching chip module, and the switching chip module forwards the first data message to the switch / router through the network interface connected to the network cable among the P network interfaces. Alternatively, after the switch / router receives the second data message, it forwards the second data message to the switching chip module through the network interface connected to the network cable among the P network interfaces, and the switching chip module receives the second data message through P ports, and forwards it to the corresponding node among the M nodes based on the IP address / MAC address of the second data message. Then, the forwarding of data messages between the multi-node server and the switch / router can be realized through the switching chip module, and there is no need to use one of the nodes in the multi-node server as a management board, and the performance of one node will not be wasted, thereby reducing costs.

[0008] In addition, the multi-node server can obtain the access status of each network interface among the M network interfaces, and the access status is used to indicate whether the network interface is connected to the network cable. When P is greater than or equal to 2, and the multi-node server determines that at least 2 network interfaces among the P network interfaces are connected to the network cable based on the access status, the multi-node server can select one of the at least 2 network interfaces as the target network interface, and open the target network interface, and close the other network interfaces among the at least 2 network interfaces except the target network interface, thereby solving the problem of network loopback between the multi-node server and the switch / router.

[0009] In some feasible implementations, each of the M nodes obtains the access status of the corresponding network interface among the M network interfaces, and the master node among the M nodes obtains the access status of each of the M network interfaces from each of the M nodes, thereby enabling the multi-node server to obtain the access status of each of the M network interfaces.

[0010] In some feasible implementations, the multi-node service also includes a CPLD chip, which connects each of the M nodes. Each of the M nodes sends the access status of the corresponding network interface to the CPLD chip, and the master node obtains the access status of each of the M network interfaces from the CPLD chip, so that the master node can obtain the access status of each of the M network interfaces.

[0011] In some feasible implementations, the master node opens the target network interface and closes the other network interfaces among at least two network interfaces except the target network interface, thereby enabling a multi-node server to open the target network interface and close the other network interfaces among at least two network interfaces except the target network interface, solving the problem of network loopback.

[0012] In some feasible implementations, each of the M network interfaces includes a physical layer chip and a registered socket RJ45 interface, and each of the M nodes is connected to a corresponding physical layer chip, wherein the physical layer chip and the RJ45 interface are connected correspondingly. Each of the M nodes obtains the link status of the corresponding physical layer chip in the M network interfaces, where the connection status is connected or not connected, and the link status is used as the access status to obtain the access status of each of the M network interfaces, thereby enabling the multi-node server to obtain the access status of each of the M network interfaces.

[0015] The M nodes are used to obtain access status of a corresponding network interface among the M network interfaces, where the access status is used to indicate whether the network interface is connected to a network cable;

[0016] The M nodes are further configured to select one of the at least two network interfaces as the target network interface when P is greater than or equal to 2 and it is determined based on the access situation that at least two of the P network interfaces are connected to the network cable;

[0017] The M nodes are further used to open the target network interface and close other network interfaces among the at least two network interfaces except the target network interface.

[0018] In some feasible implementations, each of the M nodes is used to obtain the access status of the corresponding network interface among the M network interfaces; and the master node among the M nodes is used to obtain the access status of each of the M network interfaces from each of the M nodes.

[0019] In some feasible implementations, the multi-node service also includes a CPLD chip, which connects each of the M nodes; each of the M nodes is used to send the access status of the corresponding network interface to the CPLD chip; and the master node is used to obtain the access status of each of the M network interfaces from the CPLD chip.

[0020] In some feasible implementations, the master node is further configured to open the target network interface, and close other network interfaces among the at least two network interfaces except the target network interface.

[0021] In some feasible implementations, each of the M network interfaces includes a physical layer chip and a registered socket RJ45 interface, and each of the M nodes is respectively connected to a physical layer chip, wherein the physical layer chip and the RJ45 interface are correspondingly connected; each of the M nodes is also used to obtain the link status of the corresponding physical layer chip in the M network interfaces, where the connection status is connected or not connected, and the link status is used as the access status to obtain the access status of each of the M network interfaces.

[0038] The embodiments of the present application provide a network interface control method and a multi-node server, which are used to control the network interface of the multi-node server to solve the problem of network loopback.

[0039] The embodiments of the present application are described below in conjunction with the accompanying drawings.

[0040] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0041] For example, see Figure 1 2 is a schematic diagram of a structure of a multi-node server 100 , wherein the multi-node server 100 includes four nodes, namely nodes 110 - 140 .

[0042] It should be noted that the multi-node server 100 is a server with multiple nodes. A node is also called a node server. The function of a node is equivalent to that of a single-node server. Therefore, the multi-node server 100 can be understood as multiple servers centrally deployed in one space.

[0043] In actual application scenarios, the multi-node server 100 has high scalability, high availability, and high manageability. High scalability means that nodes can be added or reduced in the multi-node server as demand and load change. High availability means that by transferring applications on failed nodes to backup nodes, the multi-node server 100 can increase normal operation time to more than 99.9%, greatly reducing the downtime of the multi-node server 100 and applications. High manageability means that users can remotely manage a multi-node server to achieve an effect similar to that of a stand-alone system.

[0044] As the popularity of new generation information technology represented by cloud computing, big data, mobile Internet, smart terminals, and the Internet of Things continues to accelerate, data centers are expanding rapidly, and their space and power consumption issues have become a major problem. When designing, building, and operating large data centers, data centers are developing towards a high-density model. The multi-node server 100 has the characteristics of high scalability, high availability, and high manageability, as well as energy saving and easy maintenance, and has a broad market space.

[0045] The server may have relatively large differences due to different configurations or performances, and may include at least one central processing unit (CPU) (e.g., at least one processor) and memory, and at least one storage medium for storing applications or data (e.g., at least one mass storage device). Among them, the memory and the storage medium may be short-term storage or persistent storage. The program stored in the storage medium may include at least one module, and each module may include a series of instruction operations on the server. Furthermore, the central processing unit may be configured to communicate with the storage medium and execute a series of instruction operations in the storage medium on the server. The server may also include at least one power supply, at least one wired or wireless network interface, at least one input and output interface, and / or at least one operating system, such as Windows Server, Mac OS X, Unix, Linux, FreeBSD, NetWare, etc. In some feasible implementations, the server may also be a cloud server, which is not limited here.

[0046] A server, also known as a server, is a device that provides computing services. Since the server needs to respond to service requests and process them to provide reliable services, generally speaking, the server should have the ability to undertake and guarantee services. The server needs to have strong processing power, high stability, high reliability, high security, scalability, and manageability. In an embodiment of the present application, the server may be an x86 server, which is also called a complex instruction set computer (CISC) architecture server, that is, a personal computer (PC) server, which is based on the PC architecture and uses an Intel or other x86 instruction set compatible processor chip and a Windows operating system.

[0047] Currently, among the multiple nodes of a multi-node server, one node is usually designated as a management board, which is used to connect to the network interface to access the network cable. Users can access the baseboard management controller (BMC) of each node in the multi-node server through the management board, that is, the management board can be used as a switch for each node in the multi-node server. However, if the node is used exclusively as a management board, the cost is high and the performance of the node is not fully utilized.

[0048] To this end, the present application proposes a multi-node server, which includes a switching chip module, at least M nodes and at least M network interfaces, the M nodes and the M network interfaces correspond one to one, the switching chip module includes N ports, M and N are integers greater than or equal to 2, and N is greater than M. Among them, the M nodes are connected to M ports of the N ports in a one-to-one correspondence, the P ports of the N ports that are not connected to the M nodes are connected to P network interfaces of the M network interfaces in a one-to-one correspondence, the M network interfaces are used to access network cables, and P is a positive integer less than or equal to M.

[0049] In some feasible implementations, each of the M network interfaces includes a physical layer chip and a registered jack 45 (RJ) 45 interface, and each of the M nodes is respectively connected to a physical layer chip, wherein the physical layer chip and the RJ45 interface are correspondingly connected.

[0050] Then, when at least one of the P network interfaces is connected to a network cable, the network cable can be connected to a switch / router, and the M nodes in the multi-node server can send a first data message to the switching chip module, and the switching chip module forwards the first data message to the switch / router through the network interface connected to the network cable among the P network interfaces. Alternatively, after the switch / router receives the second data message, it forwards the second data message to the switching chip module through the network interface connected to the network cable among the P network interfaces, and the switching chip module receives the second data message through P ports, and forwards it to the corresponding node among the M nodes based on the IP address / MAC address of the second data message. Then, the forwarding of data messages between the multi-node server and the switch / router can be realized through the switching chip module, and there is no need to use one of the nodes in the multi-node server as a management board, so the performance of one node will not be wasted, thereby reducing costs.

[0051] For example, Figure 2-1 As shown, the multi-node server 200 includes a switching chip module 210, four nodes 220 and four network interfaces 230. The switching chip module 210 may include eight ports, four of which are used to connect to the four nodes 220, and the other four ports are used to connect to the four network interfaces 230, and any one of the four network interfaces 230 is used to access a network cable.

[0052] In some feasible implementations, among the other 4 ports of the 8 ports that are not connected to the 4 nodes, P ports may be connected to the P network interfaces of the 4 network interfaces in a one-to-one correspondence, where P may be equal to 1, 2, 3, or 4. For example, if P is equal to 2, then 2 ports of the 4 ports are connected to 2 network interfaces of the 4 network interfaces in a one-to-one correspondence; or, if P is equal to 3, then 3 ports of the 4 ports are connected to 3 network interfaces of the 4 network interfaces in a one-to-one correspondence.

[0053] In some feasible implementations, each of the four network interfaces includes a physical layer (PHY) chip and a registered jack 45 (RJ) 45 interface, and each of the four nodes is respectively connected to a physical layer chip, wherein the physical layer chip and the RJ45 interface are correspondingly connected.

[0054] In some feasible implementations, the switch chip module may include one switch chip or two switch chips connected to each other, which is not limited here. The following description will be made by taking one switch chip and two switch chips as examples.

[0055] In some possible implementations, such as Figure 2-2 As shown, the switching chip module 220 may include a switching chip, and the switching chip includes at least 5 interfaces, such as 5 interfaces, 8 interfaces or 10 interfaces. Here, 8 interfaces are used as an example for explanation, namely port00, port01, port02, port03, port10, port11, port12, and port13. Among them, node 1 in the multi-node server 210 is connected to port00, node 2 is connected to port01, node 3 is connected to port02, and node 4 is connected to port03. And the P ports of port10, port11, port12, and port13 are connected to the P network interfaces in the four network interfaces in a one-to-one correspondence. For example, if P is equal to 2, then port10 and port13 in the four ports are connected to the network interfaces corresponding to node 1 and node 4 in the four network interfaces in a one-to-one correspondence; or, if P is equal to 3, then port10, port11, and port13 in the four ports are connected to the network interfaces corresponding to node 1, node 2, and node 4 in the four network interfaces in a one-to-one correspondence.

[0056] Among them, the four network interfaces are used to access the network cable to connect the switch / router. Among them, the switching chip is used to receive the first data message from nodes 1 to 4 through port00 to port03, and forward the first data message to the switch / router through the network interface connected to the network cable. Alternatively, the switch / router receives the second data message, sends the second data message to the switching chip through the connected network interface, and the switching chip receives the second data message through port10 to port13, and forwards it to the corresponding node among the four nodes based on the IP address / MAC address of the second data message.

[0057] Among them, the switch / router is a hardware device that connects two or more user devices and acts as a gateway between user devices. The switch / router is a dedicated intelligent network device that can read the destination address in the message and decide how to transmit the message according to the destination address; the switch / router can understand different protocols, such as the Ethernet protocol used by a local area network, the Transmission Control Protocol / Internet Protocol (TCP / IP) protocol used by the Internet, etc., so that the switch / router can analyze the destination addresses of messages sent from various types of networks, convert non-TCP / IP addresses into TCP / IP addresses, or vice versa; and then transmit each message to the destination address according to the best transmission path based on the routing algorithm, so the switch / router can connect non-TCP / IP networks to the Internet.

[0058] In some feasible implementations, the switch chip module 220 may include two connected switch chips, namely, switch chip 1 and switch chip 2, wherein switch chip 2 is connected to each node in the multi-node server 210, and switch chip 1 is used to connect M network interfaces. In some feasible implementations, the switch chip 2 and the switch chip 1 may be connected via a reduced gigabit media independent interface (RGMII) interface, or other methods, which are not limited here.

[0059] For example, Figure 2-3As shown, the switch chip 1 includes 4 ports, namely port00, port01, port02, and port03. The switch chip 2 also includes 4 ports, namely port10, port11, port12, and port13. Among them, port00 in the switch chip 2 is connected to node 1, port01 is connected to node 2, port02 is connected to node 3, and port03 is connected to node 4. Each port in the switch chip 1 is connected to a PHY chip, and each PHY chip is connected to an RJ45 interface. The switch / router can be connected from any one or more of the 4 RJ45 interfaces to enable the multi-node server 200 to connect to the network.

[0060] The switching chip is used to receive the first data message from nodes 1 to 4 through port00 to port03, and forward the first data message to the switch / router through the network interface connected to the network cable. Alternatively, the switch / router receives the second data message, sends the second data message to the switching chip through the connected network interface, and the switching chip receives the second data message through port10 to port13, and forwards it to the corresponding node among the four nodes based on the IP address / MAC address of the second data message.

[0061] Then, the switch chip 2 can receive the first data message sent by nodes 1 to 4, and forward the first data message to the switch chip 1, and the switch chip 1 forwards the first data message to the switch / router through the network interface connected to the network cable among the four network interfaces. The switch chip 1 can also receive the second data message sent by the switch / router through the network interface connected to the network cable among the four network interfaces, and forward it to the switch chip 2, and the switch chip 2 forwards the second data message to each node in the multi-node server 200 based on the IP address / MAC address in the second data message.

[0062] It can be seen that when at least one of the four network interfaces is connected to the network cable, Figure 2-4As shown, the network cable can be connected to the switch / router, and the four nodes in the multi-node server 200 can send a first data message to the switching chip module 210, and the switching chip module 210 forwards the first data message to the switch / router through the network interface connected to the network cable among the four network interfaces. Alternatively, after the switch / router receives the second data message, it forwards the second data message to the switching chip module 210 through the network interface connected to the network cable among the four network interfaces, and the switching chip module receives the second data message through P ports, and forwards it to the corresponding node among the M nodes based on the IP address / MAC address of the second data message. Then, the forwarding of data messages between the multi-node server 200 and the switch / router can be realized through the switching chip module 210, and there is no need to use one of the nodes in the multi-node server 200 as a management board, so the performance of one node will not be wasted, thereby reducing costs.

[0063] In some scenarios, due to user misoperation, the switch / router may be connected to the multi-node server 200 by pulling multiple network cables at the same time, then at least two network interfaces in the multi-node server 200 will be connected to the switch / router, that is, the switch chip 1 will be connected to the switch / router through at least two ports. Figure 2-5 As shown, the network interfaces corresponding to port 10 and port 13 in the switch chip 1 are connected to the switch / router respectively. Then, if the first data message is a broadcast message, the switch / router will forward the first data message to port 13 of the switch chip 1, and the switch chip 1 will send it to the switch / router again through port 10 based on the IP address / MAC address of the first data message, and so on, forming a network loop. The problem of network loopback may cause the first data message to be repeatedly forwarded between the multi-node server and the switch / router, forming a traffic black hole, occupying the bandwidth resources of the switch / router, affecting the forwarding of normal business data, and causing a poor user experience.

[0064] To this end, the present application provides a method for controlling a network interface, where a multi-node server can obtain the access status of each of the M network interfaces, and the access status is used to indicate whether the network interface is connected to a network cable. When P is greater than or equal to 2, and the multi-node server determines that at least 2 of the P network interfaces are connected to a network cable based on the access status, the multi-node server can select one of the at least 2 network interfaces as the target network interface, and turn on the target network interface, and turn off the other network interfaces of the at least 2 network interfaces except the target network interface, thereby solving the problem of network loopback between the multi-node server and the switch / router.

[0065] In some possible implementations, such as Figure 3-1As shown, the multi-node service 200 may also include a complex programmable logic device (CPLD) chip 240, and the CPLD chip 240 connects each of the M nodes. Exemplarily, the CPLD chip can connect the M nodes through an inter-integrated circuit (IIC) interface, or can be connected in other ways, which are not limited here. The CPLD chip 240 is used to receive the access status of the corresponding network interface sent by each of the M nodes 220, and return the access status of the corresponding network interface of each of the M nodes 220 at the request of the master node.

[0066] See also Figure 3-2 As shown, the control method of the network interface provided in the embodiment of the present application mainly includes the following steps:

[0067] 301. Each of the M nodes obtains access status of a corresponding network interface among the M network interfaces.

[0068] In some possible implementations, each of the M network interfaces may include a PHY chip and a registered socket RJ45 interface, and each of the M nodes is respectively connected to a physical layer chip, wherein the physical layer chip and the RJ45 interface are connected to each other. In the embodiment of the present application, the access status is used to indicate whether the network interface is connected to a network cable. For example, Figure 2-5 As shown, the network interfaces corresponding to port 10 and port 13 in the switching chip module are connected to network cables, and the network cables are connected to the switch / router.

[0069] In some possible implementations, each of the M nodes may obtain the link status of the corresponding physical layer chip in the M network interfaces, where the connection status is connected or not connected, and the link status is used as the access status to obtain the access status of each of the M network interfaces. For example, Figure 2-5 As shown, node 1 obtains the link status of the PHY chip connected to port 10 in the switching chip module, node 2 obtains the link status of the PHY chip connected to port 11 in the switching chip module, node 3 obtains the link status of the PHY chip connected to port 12 in the switching chip module, and node 4 obtains the link status of the PHY chip connected to port 13 in the switching chip module. Among them, the link status obtained by node 1 and node 4 is connected, and the link status obtained by node 2 and node 3 is not connected.

[0070] 302. Each of the M nodes sends access status of the corresponding network interface to the CPLD chip.

[0071] In an embodiment of the present application, after each of the M nodes obtains the access status of the corresponding network interface among the M network interfaces, each node may send the access status of the corresponding network interface to the CPLD chip.

[0072] For example, Figure 2-5 As shown, the access status sent by node 1 to the CPLD chip is accessed, the access status sent by node 2 to the CPLD chip is not accessed, the access status sent by node 3 to the CPLD chip is not accessed, and the access status sent by node 4 to the CPLD chip is accessed, so the CPLD chip obtains the access status of the corresponding network interface of each node in nodes 1 to 4.

[0073] 303. The master node obtains access status of each of the M network interfaces from the CPLD chip.

[0074] In some feasible implementations, the CPLD chip can determine the master node among the M nodes. Exemplarily, the CPLD chip can randomly determine any one of the M nodes as the master node, or determine a node as the master node based on a priority order. Exemplarily, the priority order of nodes 1 to 4 is node 1, node 2, node 3, and node 4. The CPLD chip preferentially determines node 1 as the master node. If node 1 is not connected to the multi-node server, node 2 is selected as the master node, and so on. Exemplarily, if Figure 2-5 As shown, nodes 1 to 4 are all connected to the multi-node server, and the CPLD chip designates node 1 as the master node based on the principle of preset order.

[0075] In some possible implementations, after the CPLD chip specifies a master node among the M nodes, the master node may obtain access status of each of the M network interfaces from the CPLD chip.

[0076] Through the above steps 302 to 303, the master node obtains the access status of each of the M network interfaces from each of the M nodes, and the multi-node server obtains the access status of each of the M network interfaces.

[0077] 304. When the master node determines that at least two of the P network interfaces are connected to the network cable based on the access situation, one of the at least two network interfaces is selected as the target network interface.

[0078] Exemplarily, if P is equal to 2, port10 and port13 among the four ports are connected one-to-one with the network interfaces corresponding to node 1 and node 4 among the four network interfaces; or, if P is equal to 3, port10, port11 and port13 among the four ports are connected one-to-one with the network interfaces corresponding to node 1, node 2 and node 4 among the four network interfaces.

[0079] In some possible implementations, when P is greater than or equal to 2, and the master node determines based on the access situation that only one of the P network interfaces is connected to the network cable, there is no network loopback problem, so the master node does not need to shut down any network interface. For example, if P is equal to 1, then port 10 of the four ports is connected one-to-one with the network interface corresponding to node 1 of the four network interfaces. The broadcast message sent by the node can be forwarded to the switch / router through port 10 by the switching chip module. Since the network interfaces other than the network interface corresponding to node 1 of the P network interfaces are not connected, the switch / router cannot forward the broadcast message to the switching chip module through other network interfaces, so there is no network loopback problem, so the master node does not need to shut down any network interface.

[0080] In some possible implementations, if the master node determines that at least two of the M network interfaces are connected to the network cable based on the access situation, a network loopback problem may occur. For example, if P is equal to 3, then port 10, port 11, and port 13 of the four ports are connected to the network interfaces corresponding to node 1, node 2, and node 4 of the four network interfaces in a one-to-one correspondence, wherein the network interfaces corresponding to node 1 and node 4 are both connected to the network cable. Then, when the broadcast message sent by node 1, the switching chip module can forward it to the switch / router through port 10 (or port 13). Since the network interface corresponding to node 4 is connected to the network cable in addition to the network interface corresponding to node 1 among the P network interfaces, the switch / router can forward the broadcast message to the switching chip module through the network interface corresponding to port 13, and the switching chip module forwards the broadcast message to the switch / router through port 10, and the cycle repeats, resulting in a network loopback problem. Then the master node can select one from port 10 and port 13 as the target network interface, and subsequently transmit the data message through the target network interface.

[0081] For example, Figure 2-5As shown, the network interfaces corresponding to node 1 and node 4 are connected to network cables. Assume that the master node is node 1. Node 1 can determine one of the network interfaces corresponding to node 1 and node 4 as the target network interface. For example, the network interface corresponding to node 1 is determined as the target network interface. The subsequent data message interactions between the multi-node server and the switch / router are all transmitted through the target network interface.

[0082] 305. The master node opens the target network interface, and closes the other network interfaces among at least two network interfaces except the target network interface.

[0083] In the embodiment of the present application, after the master node determines the target network interface, the target network interface can be opened, and the other network interfaces except the target network interface among the at least two network interfaces can be closed. Figure 2-5 As shown, node 1 (master node) can open the network interface corresponding to node 1 and close the network interface corresponding to node 4.
