[0024] To illustrate the technical solutions described in this application, specific embodiments are provided below, showing only the parts related to the embodiments of this application.

[0025] like Figures 1 to 3 As shown, this application provides a KVM-based computing server 1, including: a backplane 10, a management board 20, and multiple computing nodes 30, wherein the backplane 10 is connected to the management board 20 and the multiple computing nodes 30.

[0026] In some embodiments, each computing node 30 may include a node backplane 31, a graphics card 33, a host motherboard 34, and a control board 32. Each node backplane 31 may be connected to the overall backplane 10, the corresponding control board 32, the corresponding graphics card 33, and the corresponding host motherboard 34. Each control board 32 may be connected to the corresponding graphics card 33 and the corresponding host motherboard 34. Each host motherboard 34 may be connected to the corresponding graphics card 33 and the corresponding node backplane 31. Specifically, the corresponding components may refer to the components of the same computing node 30. For example, each node backplane 31, the corresponding control board 32, the corresponding graphics card 33, and the corresponding host motherboard 34 may be the same computing node 30.

[0027] In some embodiments, each control board 32 can be connected to the management board 20 via multiple network ports. The control board 32 can be used to provide KVM functionality for the compute node 30, and the management board 20 can be used to perform KVM switching operations on the compute node 30.

[0028] Specifically, KVM refers to hardware-level remote control technology that transforms the physical input / output interfaces of a server into network-accessible services. Its core functionality involves acquiring video signals via an HDMI capture card, simulating keyboard and mouse input signals via a USB chip, and providing a web interface or API for remote control. In this application, the control board 32 provides KVM functionality to the corresponding computing node 30, and the management board 20 synchronously controls the KVM functionality of each computing node 30. Therefore, the KVM-based computing server 1 of this application enables synchronous display and control of all computing nodes 30.

[0029] In some embodiments, the management board 20 can be used for internal network management. Specifically, the management board 20 can achieve network isolation between various computing nodes 30 through VLANs, preventing them from accessing each other. Port forwarding rules can be configured using iptables to enable simultaneous external access to the network services of all computing nodes 30. Further, the management board 20 may include an internal VLAN management module and a network application service module. When direct access to the control board 32 of a computing node 30 is required, different ports of the internal VLAN management module can be mapped to different computing nodes 30; when indirect access to the control board 32 of a computing node 30 is required, the network application service module can act as an intermediary; simultaneously, the management board 20 can be directly accessed via an external IP address.

[0030] Each control board 32 runs ustream and uStreamer services. The ustream service on these compute nodes 30 is responsible for capturing the KVM (keyboard, video, mouse) screens of the node host and transmitting the video streams via the WebSocket protocol. A web application can be deployed on the management board 20 as a unified KVM display front end. This web front end also connects to the ustreamer or webrtc services of each node via the WebSocket protocol to pull the KVM video streams in real time and display the KVM screens of each node on a single page, enabling centralized monitoring and operation of multiple nodes.

[0031] In some embodiments, each graphics card 33 is connected to its corresponding control board 32 and its corresponding node backplane 31 via an HDMI cable. Each node backplane 31 is connected to the overall backplane 10 via an HDMI cable. The overall backplane 10 is connected to the management board 20 via at least one HDMI cable. The management board 20 receives HDMI signals from each computing node 30 through the overall backplane 10. Specifically, the HDMI signal can be a video signal, which can be transmitted through an HDMI interface / HDMI cable. The HDMI interface can be a separate interface conforming to the HDMI standard.

[0032] HDMI (High-Definition Multimedia Interface) is a fully digital audio and video interface used to transmit uncompressed high-definition video and multi-channel audio signals. It can be connected using HDMI cables and uses the TMDS (Transition Minimized Differential Signaling) protocol defined by the HDMI specification to transmit video and audio data, as well as the DDC (Display Data Channel) and CEC (Consumer Electronics Control) protocols.

[0033] In some embodiments, the management board 20 may include a switching chip 21, which can be connected to the backplane 10 of the main unit via at least one gigabit Ethernet port. The backplane 10 can be connected to the corresponding control board 32 via the management port of the node backplane 31. Specifically, the gigabit Ethernet port can be an independent Ethernet interface conforming to the IEEE 802.3ab standard, which can be connected using a twisted-pair cable with an RJ-45 connector for transmitting IP packets encapsulated in Ethernet frames. These packets can contain data from various application layer protocols, such as web browsing, file transfer, video streaming, remote desktop, and management traffic.

[0034] In some embodiments, the host motherboard 34 can be connected to the corresponding control board 32 and the corresponding node backplane 31 via USB 2.0 ports. Each node backplane 31 can be connected to the overall backplane 10 via a USB 2.0 data cable. The overall backplane 10 can be connected to the management board 20 via at least one USB 2.0 data cable. The management board 20 can receive USB data signals from each computing node 30 via the overall backplane 10. Specifically, the USB 2.0 port can be an independent interface conforming to the USB 2.0 standard, and the USB data signal can be a simulated keyboard and mouse command.

[0035] USB (Universal Serial Bus) is a universal serial bus standard used to connect various external devices, such as keyboards, mice, USB flash drives, printers, cameras, and external hard drives. USB cables are typically used and usually include connectors such as Type-A, Type-B, Micro-B, Mini-B, and Type-C. Internally, they contain power lines and differential data pairs.

[0036] In some embodiments, each node backplane 31 can be connected to the corresponding control board 32 and the overall backplane 10 via GPIO ports, and each node backplane 31 can be connected to the corresponding control board 32 and the overall backplane 10 via power supply ports. The overall backplane 10 and the node backplane 31 can transmit GPIO signals via GPIO ports. The GPIO signals can be used to simulate a power button to achieve remote power-on or forced restart.

[0037] In some embodiments, the IPMI interface of each host motherboard 34 can be connected to the IPMI interface of the corresponding control board 32, and the IPMI interface of the backplane 10 can be connected to the IPMI interface of each node backplane 31 and the IPMI interface of each management board 20. IPMI (Intelligent Platform Management Interface) is an open standard hardware management interface specification used to define a management subsystem independent of the host operating system, processor, BIOS / UEFI.

[0038] IPMI allows system administrators to remotely monitor the physical health of servers, such as temperature, voltage, fan speed, log hardware events, remotely control power (e.g., power on, power off, restart), and remotely access the control panel. IPMI functionality can be implemented through a Baseboard Management Controller (BMC). The IPMI architecture can use a dedicated network interface, where the BMC can communicate with sensors, memory, power supplies, and fan backplanes via the system bus.

[0039] In some embodiments, the backplane 10 can communicate with the management board 20 via an I2C data line. The I2C data line is a board-level serial communication bus used to connect various low-speed peripheral devices in computer motherboards and embedded systems, such as temperature sensors, voltage sensors, fan controllers, memory, clock generators, and power management chips. SMBus is a subset and extension of I2C, focusing more on system management tasks, and is typically used in conjunction with IPMI / BMC. Both are compatible at the physical layer and underlying protocols. Chips on the board are connected via PCB traces or ribbon cables to transmit digital level signals and control commands, ranging in size from a few bytes to tens of bytes.

[0040] In some embodiments, the KVM-based computing server 1 may further include a redundant power supply 40, which can be connected to the backplane 10 of the whole machine through a 12V power port. The backplane 10 of the whole machine can be connected to each node backplane 31 through a 12V power port. The node backplane 31 can be connected to the corresponding host motherboard 34 through an ATX power port.

[0041] In some embodiments, the management board 20 can connect to an external network via an RJ45 Ethernet port. Specifically, the management board 20 can connect to the external network via a twisted-pair cable with an RJ-45 connector, transmitting data based on standard Ethernet and IP protocols. The external network can refer to a management network, typically a separate VLAN or physical network. The management board 20 transmits differential electrical signals via the twisted-pair cable. These differential electrical signals can refer to protocol messages encapsulated in Ethernet frames / IP packets. Protocol messages may include sensor data, access information, KVM data, configuration information, firmware update commands, and power control commands.

[0042] In some embodiments, the management board 20 may include a console port and multiple USB interfaces for connecting external devices. The console port is an interface based on a serial communication protocol, specifically found on servers and network devices, and can be used for low-level, out-of-band system access and debugging.

[0043] In some embodiments, the KVM-based computing server 1 may further include multiple node indicator lights and multiple switching buttons, both of which are connected to the management board 20. The node indicator lights can be used to indicate the corresponding computing node 30, and the switching buttons can be used to switch between computing nodes 30.

[0044] In this application, a control board 32 is independently set in each computing node 30, which can realize the individual control of the KVM function of the computing node 30. At the same time, a management board 20 is set up to provide multiple network ports through the backplane 10 of the whole machine, which communicates with the control board 32 of each computing node 30. This enables the display and control of the KVM of each computing node 30, improves the convenience of multi-node parallel monitoring and remote management, reduces the risk of human error, and significantly improves the response speed of fault location and handling, thereby bringing users a more efficient and intuitive operation and maintenance experience.

Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this application. Furthermore, under the teachings of this application, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this application.
