Description

Technical Field

[0001] The present invention relates to the field of server management, and in particular to a device and method for wireless network connection management of a server BMC (Baseboard Management Controller). Background Art

[0002] The BMC (Board Management Controller, a core control component on the motherboard used to manage and connect different functional modules and components on the motherboard) is an important component module of the server, enabling the components on the motherboard to operate smoothly through the management of the BMC. In addition, the BMC can also obtain the operation data of other components on the motherboard and connected hardware, and automatically send a warning message to the network administrator when detecting an abnormal situation. The network administrator then performs remote diagnosis and problem troubleshooting according to the information provided by the BMC.

[0003] As Figures 1-2 shown, the configuration of a full cabinet server usually connects PCIe (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard) NIC (Network Interface Controller, a hardware designed to allow a computer to communicate on a computer network, existing in the form of an onboard Lan network card on the motherboard and a PCIe external card) and a Switch (network switch, a network hardware that receives and forwards data to the target device through packet switching and can connect different devices on a computer network. Generally, it is also simply referred to as a switch) in series as a high-speed computing network; the operating system and the BMC are connected in series to another low-speed network for remote monitoring / control / management (monitor and remote control). The high-speed network and the low-speed network are then connected to the internal network and the external network according to requirements. When the system fails to connect, there are many possible reasons, and some reasons may occur due to poor quality of the physical line. At this time, it will be difficult to repair due to the complex wire configuration of the entire cabinet server.

[0004] In the prior art, the low-speed network for monitoring / management mostly uses a physical CAT cable (network cable, generally made of metal or glass and used to transmit network information. The common specifications on the server are cat5, that is, 100 Mbps; or cat6, that is, 1000 Mb / s) to connect to the switch to implement network deployment. The network administrator can view the server information / version / error log and perform remote power-on / off / restart through the BMC.

[0005] For large enterprises with tens of thousands of servers, the required wiring is extensive. During construction and wiring, problems such as incorrect port (connector) connections and wire length issues may occur, leading to complex construction procedures. After the subsequent servers are put into operation, if a fault needs to be eliminated, the process of checking the wires is also quite complex, which is not conducive to reducing the management and monitoring costs of the servers and improving the management and monitoring efficiency of the servers.

[0008] Optionally, the basic input / output system selects the wireless network where the wireless access point is located by configuring the BMC, the wireless access point assigns an IP to the BMC, and the wireless network access point establishes a communication connection with the BMC through the assigned IP of the BMC. After the wireless network access point establishes a communication connection with the BMC, the administrator manages the newly added server BMC through the wireless access point.

[0009] Further, the wireless access point obtains the name information of the wireless network module, the wireless network environment information, the transmission ID information, and the ID information of the BMC, generates the IP information of the BMC where the wireless network module is located according to the obtained name information of the wireless network module, the wireless network environment information, the transmission ID information, and the ID information of the BMC, and sends the generated IP information of the BMC to the wireless network module in the BMC to establish a communication connection between the wireless access point and the wireless network module, and realizes the communication connection between the wireless access point and the BMC where the wireless network module is located according to the communication connection between the wireless access point and the wireless network module.

[0010] Further, before the wireless network module establishes a communication connection with the wireless access point, after receiving and setting the IP information of the BMC sent by the wireless access point, a restart operation is performed.

[0011] Optionally, the wireless access point is communicatively connected to the BMCs of multiple servers in the whole cabinet, enabling batch management, control, and monitoring of the multiple servers in the whole cabinet.

[0012] Furthermore, the servers in the whole cabinet further include a first type of network card and a second type of network card.

[0033] To clearly illustrate the technical features of this solution, the present invention will be elaborated in detail below through specific implementation manners and in conjunction with its accompanying drawings. The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. It should be noted that the components illustrated in the drawings are not necessarily drawn to scale. The present invention omits the description of well-known components and processing technologies and processes to avoid unnecessarily limiting the present invention.

[0034] Embodiment 1

[0035] As Figures 3-4 shown, the present invention provides a device for wireless network cascading management of a BMC, including: a wireless network module (Wi-Fi module), a BMC, a basic input / output system (BIOS), and a wireless access point (Wi-Fi AP). The wireless network module is integrated inside the BMC and is used for communication connection between the BMC and the wireless access point; the basic input / output system is communicatively connected to the BMC and is used to wake up the BMC when the server is powered on, initialize the wireless network module, and establish a communication connection between the wireless network module and the wireless access point; the wireless access point realizes the management, control, and monitoring of the server through communication with the BMC.

[0036] Among them, a wireless network module (wireless network module) is added to the BMC interface on the server motherboard. After the server PSU is powered on, the basic input / output system BIOS first performs initialization, then wakes up the BMC, and then initializes the wireless network module. At this time, the wireless network module starts to capture the wireless network environment.

[0037] The Basic Input / Output System configures the BMC to select the wireless network where the wireless access point is located. The wireless access point assigns an IP address to the BMC. The wireless network access point establishes a communication connection with the BMC through the assigned IP address of the BMC. After the wireless network access point establishes a communication connection with the BMC, the administrator manages the newly added server BMC through the wireless access point. A local area network is formed through Wi-Fi network connection, and network administrators can use any wireless network connection device (wireless access point) as the management device. When the server reports an error, it can be immediately displayed on the management device, and the error reporting log transmission function can be implemented to facilitate technicians to further troubleshoot problems.

[0038] Specifically, as Figure 5 shown, the wireless access point obtains the name information of the wireless network module (Wi-Fi module initial), the wireless network environment information (detect Wi-Fi environment), the transmission ID information (choose environment in BIOS setup menu and transfer ID), and the ID information of the BMC (Wi-Fi BMC ID). According to the obtained name information of the wireless network module, the wireless network environment information, the transmission ID information, and the ID information of the BMC, it generates the IP information of the BMC where the wireless network module is located (Assign BMC IP), and sends the generated IP information of the BMC to the wireless network module in the BMC. According to the generated IP information of the BMC, a communication connection is established between the wireless access point and the wireless network module. According to the communication connection between the wireless access point and the wireless network module, a communication connection is realized between the wireless access point and the BMC where the wireless network module is located.

[0039] Specifically, according to the obtained name information of the wireless network module, the wireless network environment information, the transmission ID information, and the ID information of the BMC, generating the IP information of the BMC where the wireless network module is located (Assign BMC IP) can specifically be to pre-establish a mapping relationship table. The mapping relationship table stores the mapping relationship between the name information of the wireless network module, the wireless network environment information, the transmission ID information, the ID information of the BMC, and the IP information of the BMC where the wireless network module is located. According to the obtained name information of the wireless network module, the wireless network environment information, the transmission ID information, and the ID information of the BMC, search for and match the corresponding IP information of the BMC where the wireless network module is located in the mapping relationship table; it can also be other determination methods, and the present invention does not limit this here.

[0040] Further, before the wireless network module establishes a communication connection with the wireless access point, after receiving and setting the IP information of the BMC sent by the wireless access point, a restart operation is performed. That is, the wireless network module completes the first network setting according to the assigned IP information of the BMC. After that, the wireless network module in the BMC, that is, the Wi-Fi module needs to be restarted, and the communication connection between the wireless access point and the wireless network module will be automatically established. That is, the wireless access point can communicate with the BMC where the wireless network module is located.

[0041] Among them, the wireless access point can communicate with the BMCs of multiple servers in the whole cabinet, realizing batch management, control, and monitoring of multiple servers in the whole cabinet.

[0042] When it comes to the management of the BMCs of multiple servers in the whole cabinet, the servers in the whole cabinet also include a first type of network card (PCI-E NIC) and a second type of network card (NIC). The first type of network card is communicatively connected to a first switch (switch#1), the second type of network card is communicatively connected to a second switch (switch#2), and the first type of network card and the second type of network card are communicatively connected to each other.

[0043] Among them, the first switch is set in the high-speed computing network, and the second switch is set in the low-speed computing network. The number of the first type of network cards is multiple, and the number of the second type of network cards is one. The multiple first type of network cards are arranged in parallel, with one end respectively communicatively connected to different network ports of the first switch, and the other end of the multiple first type of network cards is also communicatively connected to one end of the second type of network card. The specification of the second type of network card can be 1G / 10G, and the other end of the second type of network card is communicatively connected to the network port of the second switch. Further, the first switch in the high-speed computing network can be communicatively connected to a terminal running a high-speed network application (high-speed application, such as AI HPC storage), and the second switch in the low-speed computing network can be communicatively connected to a terminal running a low-speed network application (low-speed application, that is, monitor & remote control).

[0044] A local area network is formed through Wi-Fi network connection. The network administrator can use the wireless access point as the management device to manage multiple server BMCs in the entire cabinet, or manage multiple server BMCs in multiple entire cabinets in the computer room. When a certain server reports an error, it can be immediately displayed on the management device, and the location of the corresponding server can be determined according to the IP information assigned to the BMC of the error-reporting server, realizing the rapid and accurate positioning of the error-reporting server, and the error log transmission function can be implemented to facilitate technicians to further troubleshoot. After the wireless network module is connected to the wireless network, it automatically identifies the wireless access point. As long as the server information is captured from the monitoring device (wireless access point), it can be paired with one key. The wireless connection method does not require physical line connection. For low-speed networks, half of the wires can be saved, thus saving costs.

[0045] In the technical solution of the present invention, the wireless network module is integrated inside the BMC and is used for the communication connection between the BMC and the wireless access point; the basic input / output system is communicatively connected to the BMC and is used to wake up the BMC when the server is powered on and initialize the wireless network module to establish a communication connection between the wireless network module and the wireless access point; the wireless access point realizes the management, control, and monitoring of the server through communication with the BMC, effectively solving the problems of high cost and low efficiency in server monitoring and management in the prior art, effectively improving the server monitoring and management efficiency, and reducing the server monitoring and management cost.

[0046] In the technical solution of the present invention, the wireless access point generates the IP information of the BMC where the wireless network module is located according to the obtained name information, wireless network environment information, transmission ID information, and BMC ID information of the wireless network module. According to the IP information of the BMC where the wireless network module is located, a communication connection between the wireless access point and the wireless network module is established. According to the communication connection between the wireless access point and the wireless network module, a communication connection between the wireless access point and the BMC where the wireless network module is located is realized, ensuring the accuracy and reliability of the communication between the wireless access point and the BMC.

[0047] In the technical solution of the present invention, the wireless access point is communicatively connected to the BMCs of multiple servers in the entire cabinet to realize the batch management, control, and monitoring of multiple servers in the entire cabinet.

According to the obtained name information, wireless network environment information, transmission ID information, and BMC ID information of the wireless network module, the IP information of the BMC where the wireless network module is located (Assign BMC IP) is generated, and the generated BMC IP information is sent to the wireless network module in the BMC. According to the generated BMC IP information, a communication connection between the wireless access point and the wireless network module is established, and based on the communication connection between the wireless access point and the wireless network module, a communication connection between the wireless access point and the BMC where the wireless network module is located is realized.

[0059] Specifically, according to the obtained name information, wireless network environment information, transmission ID information, and BMC ID information of the wireless network module, generating the IP information of the BMC where the wireless network module is located (Assign BMC IP) can specifically be to pre-establish a mapping relationship table, which stores the mapping relationship between the name information, wireless network environment information, transmission ID information, BMC ID information of the wireless network module, and the IP information of the BMC where the wireless network module is located.
