[0002] A blade server is a server structure that inserts multiple blade - type server units into a standard - height rack - type chassis to achieve a higher available density within a limited space.

[0038] Embodiment 1

[0039] Figure 1 It is a schematic structural diagram of a monitoring device for a blade server according to Embodiment 1 of the present utility model. A monitoring device for a blade server, as Figure 1 shown, includes: multiple groups of monitoring units, where each group of monitoring units includes:

[0040] An intelligent platform management controller or a baseboard management controller for calculating the use of blades, which is used to obtain the operation information of the components on the computing blade, manage the components on the computing blade, and manage the interface between the system management software and the platform hardware;

[0041] The Intelligent Platform Management Controller (IPMC) is a remote monitoring and management technology for the physical health characteristics of server boards, network devices, and data centers. It operates independently of the server's processor, BIOS, or operating system and is a management subsystem that runs independently within the system, providing the ability to monitor, control, and perform initial settings on the hardware system inside the chassis. The operating information of the hardware inside the chassis, including the temperature, voltage, fan speed, power status, etc., can be obtained and monitored through the Intelligent Platform Management Controller. It can also remotely control the server to perform management operations such as startup, shutdown, restart, reset, or power-off.

[0042] The Baseboard Management Controller (BMC) is an embedded management controller located on the server board but independent of other hardware in the system. It is an independent management subsystem under the host server system. The server's system management software can obtain the operating information provided by the platform hardware interface through the Baseboard Management Controller and mainly perform remote operations such as monitoring and managing the server through the platform hardware interface. It is used to support the system management software to monitor the health status such as temperature and voltage of the server's CPU, memory, hard disk, fan, chassis, etc. hardware, and can also remotely control the server to perform operations such as shutdown, restart, update, reset, power-on and power-off. In the case of the host hardware or operating system crashing or shutting down, the BMC can still manage the host system. Therefore, it is also used to record detailed information of the server such as: model, manufacturer, date, production and technical information of each component, chassis information, motherboard information, etc., and perform management operations on the server such as: log management, user management, BIOS management, alarm management, etc.

[0043] The compute blade is a blade single board that provides computing power in a blade server and undertakes important tasks such as computing tasks in data processing. Especially when dealing with compute-intensive work, it is necessary to monitor the operating status of the compute blade to ensure its stable operation. Through the Intelligent Platform Management Controller or the Baseboard Management Controller, the operating information such as the health status of the components on the compute blade can be obtained, the compute blade can be monitored, and corresponding debugging can be performed on the compute blade, which can be used as an information reference and auxiliary tool during the regular maintenance of the compute blade, thereby ensuring the stable computing power performance of the blade server.

[0044] The MCU is used to process the information provided by the Intelligent Platform Management Controller or the Baseboard Management Controller and return the processed control information to the Intelligent Platform Management Controller or the Baseboard Management Controller;

[0045] The MCU is a microcontroller unit or single-chip microcomputer. The MCU can process the operation information of the computing blade provided by the intelligent platform management controller or the baseboard management controller. The processed operation information can be used as a reference for the staff when maintaining the computing blade. According to the operation information of the computing blade, the staff issues corresponding control instructions, which are processed by the MCU and sent as control information to the intelligent platform management controller or the baseboard management controller, so as to perform maintenance operations on the computing blade.

[0048] The interface connector is a hardware interface connected to the intelligent platform management controller or the baseboard management controller. The interface connector can be electrically connected to the communication interface led out by the intelligent platform management controller or the baseboard management controller. The interface connector is connected to the MCU through the CAN bus. When the interface connector is connected to the communication interface of the intelligent platform management controller or the baseboard management controller, the MCU can formulate a set of transmission protocols with the intelligent platform management controller or the baseboard management controller based on the CAN bus. Correspondingly, the communication interface of the intelligent platform management controller or the baseboard management controller should also be led out based on the CAN bus. The interface connector can obtain the operation information of the computing blade provided by the intelligent platform management controller or the baseboard management controller through the CAN bus, and then send the operation information of the computing blade to the MCU through the CAN bus. The MCU processes the operation information of the computing blade as a data reference for the staff to maintain the computing blade. The interface connector can also receive the control information of the computing blade sent by the staff. The control instructions sent by the staff are processed by the MCU as control information and transmitted to the interface connector through the CAN bus. The interface connector sends the control information to the intelligent platform management controller or the baseboard management controller through the CAN bus to control the computing blade. Each monitoring unit can be connected to a computing blade for debugging. Multiple groups of monitoring units can be respectively connected to multiple computing blades to debug multiple computing blades simultaneously, which can effectively improve the overall maintenance efficiency of the blade server.

[0049] An optional implementation manner of this embodiment is that, in order to improve the maintenance efficiency of the blade server, the interfaces on the interface connector are reversible interfaces. When connecting to the communication interfaces of the intelligent platform management controller or the baseboard management controller, it is no longer necessary to distinguish the front and back of the interfaces, which simplifies the operation during interface connection.

[0050] In this embodiment, the intelligent platform management controller or the baseboard management controller is electrically connected to the MCU through the interface connector, and a transmission channel between the intelligent platform management controller or the baseboard management controller and the MCU is established based on the CAN bus. Utilizing the characteristics of the CAN bus, the connection method and communication method with the computing blade are more flexible, enabling flexible transmission of the operation information and control information of the computing blade, facilitating the expansion of connection to multiple modules for assisting in debugging the computing blade. The MCU processes the operation information of the computing blade obtained via the interface connector, providing data reference for the staff to debug the computing blade. The staff issues control instructions based on the operation information of the computing blade, and the MCU processes the control instructions and transmits the control information to the computing blade through the interface connector.

[0051] In this embodiment, a preferred implementation manner is that, in order to facilitate the debugging operation of the computing blade, the monitoring unit further includes a wireless module, and the wireless module is used for transparently transmitting and forwarding the debugging commands of the IPMC and BMC obtained by the MCU. The wireless module is electrically connected to the MCU;

[0052] The wireless module can establish a wireless connection with the debugging host computer, and is used for wireless maintenance operation of the blade server within a certain range. The wireless module is electrically connected to the MCU and transmits information with the MCU. The wireless module has a transparent transmission function. The wireless module can receive the operation information of the computing blade provided by the intelligent platform management controller or the baseboard management controller processed by the MCU, and send the operation information of the computing blade to the debugging host computer in a wireless communication manner. The wireless module can also transparently transmit and forward the debugging commands of the IPMC and BMC obtained by the MCU to the debugging host computer. Utilizing the characteristics of the CAN bus, more comprehensive operation information of the computing blade can be obtained. The debugging host computer can directly access the corresponding debugging interface, and transmit the control instructions to the MCU through the wireless module for transparent transmission to perform wireless debugging on the computing blade. It is no longer necessary to adjust the permissions when the host computer is directly connected to the computing blade, and it can also avoid interference with the original on-site wiring in the wired manner. In the case of a confined space where wired connection is not allowed, the computing blade can be flexibly debugged, improving the maintenance efficiency of the blade server. When the debugging host computer remotely accesses the MCU through the wireless module, the monitoring unit is in the transparent transmission mode.

[0059] To enable the MCU to work continuously, a power supply module with a switchable power supply mode is adopted in this embodiment. When the interface connector switches the connection between the computing blades, uninterrupted power supply to the MCU is ensured. The power supply module powers the MCU in two ways: by using its own battery and by taking power from the interface. The switching of the power supply mode is achieved through an electronic switch, and in cooperation with the voltage stabilizing circuit, there is no power outage during the switching of the power supply mode. The power pin of the interface connector can be connected to one of the power outputs of the power supply module of the blade server to supply power using the power supply module of the blade server. The input ends of the electronic switch in the power supply module are electrically connected to the battery and the interface connector respectively, the output end of the electronic switch is electrically connected to the input end of the voltage stabilizing circuit, and the output end of the voltage stabilizing circuit is electrically connected to the power supply end of the MCU. The electronic switch switches the power supply mode by identifying the input voltage of the interface connector.

A charging circuit is also provided between the battery and the interface connector to charge the battery by taking power from the interface connector. The input end of the charging circuit is electrically connected to the interface connector, and the output end of the charging circuit is electrically connected to the battery to ensure the battery's endurance and enable the MCU to work continuously for a long time.

[0062] The display control module is electrically connected to the MCU and transmits information to the MCU, and displays the operation information of the computing blade obtained by the MCU to the staff, serving as a data reference for the staff to debug the computing blade. The staff can intuitively issue control commands for the computing blade to the MCU at any time based on the displayed information, and the MCU processes the commands and transmits control information to the computing blade through the interface connector. The staff can directly issue control commands to the blade server on-site according to the real-time operation information of the computing blade they have mastered, which enables immediate debugging of the computing blade and improves the maintenance efficiency of the blade server.
