[0035] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] As the computing performance of CPUs installed in servers becomes stronger and stronger, the number of CPU pins and channels is increasing. The traditional server architecture design of a single motherboard with two CPUs may become a thing of the past, and it will be replaced by an architecture design of dual or even multiple motherboards with a single CPU. The computing performance of a single CPU can already unleash the full potential of the motherboard, and servers using two or even more motherboards are gradually being widely adopted.

[0037] In related technologies, such as Figure 1 As shown in the figure, the BMC board card generally controls a single motherboard after being connected to the motherboard through the DC-SCM interface. In other words, if you want to control two or more motherboards, you need two or more complete daughter cards equipped with BMC. However, this architecture that requires two or more complete daughter cards plus a motherboard causes a waste of BMC chip and board resources, and seriously increases procurement and maintenance costs.

[0038] In the embodiment of the present invention, based on the core technical concept of using PCIe MUX (PCI Express Multiplexer, PCI Express multiplexer) to realize that a single baseboard management controller controls two or more mainboards at the same time, the mainboard control system in the related art is improved. The present invention will be described in detail below with reference to the accompanying drawings:

[0039] Reference Figure 2 , shows a schematic diagram of the structure of a mainboard control system provided by some embodiments of the present invention, the system comprising:

[0040] Baseboard management controller;

[0041] A multiplexer, wherein a signal input terminal of the multiplexer is connected to a signal output terminal of the baseboard management controller;

[0042] The main board at least comprises a first main board and a second main board, and the signal input ends of the first main board and the second main board are respectively connected to the signal output ends of the multiplexer.

[0043] In the specific implementation, the MUX chip itself is a multiplexer. The MUX chip is an important digital integrated circuit used to select one output from multiple input signals, that is, to select the signal channel through circuit switching. Therefore, there is a hot-swap requirement for system engineering. With the development of technology, the performance and stability of the MUX chip are constantly improving. Therefore, Figure 2 As shown, the signal input end of the multiplexer can be connected to the signal output end of the baseboard management controller, and the mainboard is set to include at least a first mainboard and a second mainboard, and the signal input ends of the first mainboard and the second mainboard are respectively connected to the signal output end of the multiplexer, and the BMC sends a signal to control the PCIE MUX to select a data channel to switch the two mainboards.

[0044] Specifically, in response to the user's motherboard control requirements, the target motherboard that the user intends to control can be determined between the first motherboard and the second motherboard; and a switching signal is sent to the multiplexer through the baseboard management controller to control the multiplexer to establish a signal path between the baseboard management controller and the target motherboard according to the switching signal.

[0045] In some embodiments of the present invention, the multiplexer includes at least a first multiplexer and a second multiplexer; the video graphics array signal output end and the serial communication protocol signal output end of the baseboard management controller are respectively connected to the signal input end of the first multiplexer; the universal serial bus signal output end and the serial communication protocol signal output end of the baseboard management controller are respectively connected to the signal input end of the second multiplexer; the video graphics array signal input ends of the first mainboard and the second mainboard are respectively connected to the signal output end of the first multiplexer; the universal serial bus signal input ends of the first mainboard and the second mainboard are respectively connected to the signal output end of the second multiplexer.

[0046] In practical applications, such as Figure 3 As shown, a first multiplexer can be set to switch display signals (such as VGA (Video Graphics Array) signals), and a second multiplexer can be set to switch USB signals for operating servers and monitoring the real-time status of servers through BMC chips; specifically, the video graphics array signal output terminal and the serial communication protocol signal output terminal of the baseboard management controller can be respectively connected to the signal input terminal of the first multiplexer; the universal serial bus signal output terminal and the serial communication protocol signal output terminal of the baseboard management controller can be respectively connected to the signal input terminal of the second multiplexer; the video graphics array signal input terminals of the first mainboard and the second mainboard are respectively connected to the signal output terminal of the first multiplexer; the universal serial bus signal input terminals of the first mainboard and the second mainboard are respectively connected to the signal output terminal of the second multiplexer.

[0047] That is to say, a VGA PCIE signal can be led out from the BMC and connected to the first PCIE MUX chip (i.e., the first multiplexer), and then two signals are connected from the PCIE MUX chip to the VGA signal input terminals of two different motherboards respectively; similarly, a USB PCIE signal can be led out from the BMC and connected to the PCIE MUX chip, and then two signals are connected from the second PXIE MUX chip (i.e., the second multiplexer) to the USB signal input terminals of two different motherboards respectively; and an ESPI or SGPIO PCIE signal is led out from the BMC and connected to the PCIE MUX chip to control the signal path selection of the PCIE MUX chip. It should be emphasized that in this embodiment, the switching of the VGA signal and the USB signal cannot be performed simultaneously; wherein, SGPIO is a serial communication protocol used to connect a computer motherboard and a hard disk backplane, and ESPI (Enhanced Serial Peripheral Interface) is a serial peripheral interface specially designed for connecting a processor and various peripherals.

[0048] Furthermore, the baseboard management controller can send a switching signal to the signal input terminals of the first multiplexer and the second multiplexer according to the serial communication protocol signal output terminal, thereby controlling the first multiplexer and the second multiplexer to establish a switching signal according to the switching signal. Figure 3 The video graphics array signal path and the universal serial bus signal path between the baseboard management controller and the target motherboard are shown to achieve the switching of motherboard control.

[0049] Further, since the implementation scheme of the present invention is based on the MUX chip, the fundamental principle of its signal channel selection is the switching of the circuit channel, so the premise of the actual implementation of the present invention is that the BMC chip used must select an OS driver that supports the hot-swap function of PCIE (i.e., the hot-swap process hot remove and hot add of the PCIE standard) to support the hot-swap function (VGA\USB\MCTP). Since the BMC chip is preset to be mounted on the mainboard 1 (i.e., the first mainboard) in this embodiment, the management of the system and components (such as fans, etc.) of the mainboard 2 (i.e., the second mainboard) can use I2C (Inter-Integrated Circuit, integrated circuit bus), so the equipment of the PCIE bus on the mainboard 2 must support the components that use I2C to obtain the temperature, and the BMC can develop an I2C component monitoring function; the server can monitor the internal information of the server through I2C, for example, it can monitor and feedback the temperature information, fan speed information, etc. to the BMC; the fan speed can also be adjusted through I2C by the BMC to achieve the purpose of controlling the temperature. It is possible to obtain component temperature information when BMC controls switching; BMC can send an interrupt signal to PCIE MUX through out-of-band management to support PCIE MUX switching between two mainboards, because BMC out-of-band management switching requires BMC firmware\MCTP over PCIE support. The firmware needs to adapt to the dynamic switching of interfaces between the two hosts (H2B and KCS); and it does not support dual systems using MCTP over PCIE monitoring and management at the same time. Only the system that currently mounts the BMC can support it, and only one HOST system USB interface can be used at the same time. In other words, this embodiment can switch once when the OS system is turned on to enumerate all asset information on the dual systems, and then switch back to the main system, so the corresponding PCIE driver and PCIE device firmware can be installed, and hot-swap function is supported; among them, MCTP (Management Component Transport Protocol) is the management component transmission protocol, and PCIe is a high-speed serial computer expansion bus standard. It is the largest interface on the computer motherboard. Network cards, sound cards, independent graphics cards, and video capture cards all use this interface. H2B (Host to BMC) refers to a module function in the BMC chip, which is used to convert PCIe access to bus access connected to NIC400; KCS: Keyboard Controller Style, keyboard controller mode. BMC: Baseboard Management Controller, is a dedicated service processor that uses sensors to monitor the status of a computer, network server, or other hardware drive devices. Out-of-band management is a management system independent of the main network, which monitors, configures, and controls devices through a dedicated management channel.It allows IT teams to access devices at will, whether the device is turned on or off, locally or remotely, and whether the device is inside or outside the company firewall. The main advantage of out-of-band management is that it provides better access rights and functions because it runs on hardware and can work below the operating system. This management method manages storage devices through different channels, including but not limited to using the device network port or serial port, and performing operations and maintenance through tools such as Telent, SSH, FTP, etc. Out-of-band management is widely used in equipment maintenance and operation monitoring, including initial configuration, upgrades, and fault maintenance of equipment.

[0050] Further, in one example, the DC-SCM interface and the BMC management board can continue to be used and based on the same technical concept, a single baseboard management controller can simultaneously control two or more mainboards. Specifically, Figure 4 As shown, an additional Y-type cable and a PCIE MUX and a PCIE clock MUX (i.e. Figure 4 The VGA signal is distinguished from other signals, and the system management signal is further connected to the two main boards through the DC-SCM connector and the Y-cable to control the dual main boards. The VGA signal and its clock and reset signals are led to the MCIO connector by the Y-cable; specifically, since the hardware constructs the PCIE in-place signal and the corresponding part of the management signal, and a lot of modifications are required to the CPLD, the hot switching of VGA and USB cannot be performed at the same time. Therefore, in one example, when performing PCIE switching of dual HOSTs, two systems are used, that is, main board one and main board two work at the same time; after normal boot, the BMC chip can select main board one as the control board by default, and when the interrupt operation is sent through the software, the hot remove process (standard PCIE hot plug process) can be executed, and the MCIO signal of main board one will be hot removed, and then the hot In the add step, the VGA clock and data signals of the second motherboard are connected to the MCIO end through the PCIE cable and then connected to the second motherboard to achieve the switching purpose. Among them, except for the VGA signal, DC-SCM will uniformly control all other signals; A, B, and C refer to different functional pins of the chip respectively. The BMC management board is the board equipped with BMC connected to the motherboard through the DC-SCM interface. The full name of the MCIO connector is Mini Cool Edge IO, which is an interface technology that merges multiple physical channels into a high-speed data stream, which can be called multi-channel input / output.

[0051] In some embodiments of the present invention, the baseboard management controller is disposed on the first mainboard, and an integrated circuit bus signal terminal of the baseboard management controller is connected to a management component transmission protocol signal terminal of the second mainboard.

[0052] In practical applications, since the implementation scheme of the present invention is based on the MUX chip, the fundamental principle of selecting the signal channel is the switching of the circuit channel, so the premise of the actual implementation of the present invention is that the BMC chip used must select an OS driver that supports the hot-swap function of PCIE (i.e., the hot-swap process hot remove and hot add of the PCIE standard) to support the hot-swap function (VGA\USB\MCTP). Since the BMC chip is preset to be mounted on the mainboard 1 (i.e., the first mainboard) in this embodiment, the management of the system and components (such as fans, etc.) of the mainboard 2 (i.e., the second mainboard) can use I2C, so the device of the PCIE bus on the mainboard 2 must support the use of I2C to obtain the temperature of the component, and the BMC can develop the I2C component monitoring function; the server can monitor the internal information of the server through I2C, for example, it can monitor and feedback the temperature information, fan speed information, etc. to the BMC; the fan speed can also be adjusted through I2C by the BMC to achieve the purpose of controlling the temperature. It is realized that the component temperature information can still be obtained when the BMC control is switched.

Specifically, in response to the user's mainboard control requirements, the target mainboard that the user intends to control can be determined to switch to the target mainboard in the subsequent switching process and control the target mainboard.

[0056] Step 502: Send a switching signal to the multiplexer through the baseboard management controller to control the multiplexer to establish a signal path between the baseboard management controller and the target mainboard according to the switching signal.

[0059] Sending the switching signal to the signal input terminals of the first multiplexer and the second multiplexer through the baseboard management controller according to the serial communication protocol signal output terminal;

[0060] The first multiplexer and the second multiplexer are controlled to establish a video graphics array signal path and a universal serial bus signal path between the baseboard management controller and the target mainboard according to the switching signal.

[0061] In the specific implementation, Figure 3 As shown, the first multiplexer and the second multiplexer can be set to switch the display signal (such as VGA signal) and the USB signal used to operate the server through the BMC chip to monitor the real-time status of the server respectively; specifically, the video graphics array signal output terminal and the serial communication protocol signal output terminal of the baseboard management controller can be set to be connected to the signal input terminal of the first multiplexer respectively; the universal serial bus signal output terminal and the serial communication protocol signal output terminal of the baseboard management controller are connected to the signal input terminal of the second multiplexer respectively; the video graphics array signal input terminals of the first mainboard and the second mainboard are connected to the signal output terminal of the first multiplexer respectively; the universal serial bus signal input terminals of the first mainboard and the second mainboard are connected to the signal output terminal of the second multiplexer respectively.

[0062] That is to say, a VGA PCIE signal can be led out from the BMC and connected to the first PCIE MUX chip (i.e., the first multiplexer), and then two signals are connected from the PCIE MUX chip to the VGA signal input terminals of two different motherboards respectively; a USB PCIE signal can be led out from the BMC and connected to the PCIE MUX chip, and then two signals are connected from the second PXIE MUX chip (i.e., the second multiplexer) to the USB signal input terminals of two different motherboards respectively; an ESPI or SGPIO PCIE signal can be led out from the BMC and connected to the PCIE MUX chip to control the signal path selection of the PCIE MUX chip.

[0063] Furthermore, the baseboard management controller can send a switching signal to the signal input terminals of the first multiplexer and the second multiplexer according to the serial communication protocol signal output terminal, thereby controlling the first multiplexer and the second multiplexer to establish a switching signal according to the switching signal. Figure 3 The video graphics array signal path and the universal serial bus signal path between the baseboard management controller and the target motherboard are shown to achieve the switching of motherboard control.

[0064] In some embodiments of the present invention, the baseboard management controller is disposed on the first mainboard, an integrated circuit bus signal terminal of the baseboard management controller is connected to a management component transmission protocol signal terminal of the second mainboard, and the method further comprises:

[0065] Obtaining component information fed back by the second mainboard through the management component transmission protocol signal terminal through the integrated circuit bus signal terminal of the baseboard management controller; wherein the component information at least includes fan speed information and temperature information;
