DETAILED DESCRIPTION

[0018] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0019] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0020] In the following description, the terms "first\second" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0021] Unless otherwise defined, all technical and scientific terms used in this disclosure have the same meaning as those commonly understood by those skilled in the art to which this disclosure belongs. The terms used in this disclosure are only for the purpose of describing the embodiments of this disclosure and are not intended to limit this disclosure.

[0022] It should be understood that in the various embodiments of the present disclosure, the size of the serial number of each implementation process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0023] Since customer requirements are always complex and changeable, general projects usually require support for multiple model configurations at the beginning of the project. Since the changes in these model configurations generally only involve the hard disk backplane and cooling strategy, it is usually possible to use a set of BMC, Basic Input Output System (BIOS) and Complex Programmable Logic Device to fully adapt, without the need to develop a separate version. The most commonly used solution at present is that the BMC uses a custom Original Equipment Manufacturer (OEM) command to write the switching flag to the Electrically Erasable Programmable Read-Only Memory (EEPROM). After that, the BMC needs to be restarted to reload the corresponding model configuration driver and the corresponding cooling strategy. If the machine is in the power-on state at this time, it is also necessary to restart the machine, and the BMC needs to re-acquire the machine model configuration information.

[0024] The disadvantages of this solution are mainly reflected in two aspects: when the production line switches the model configuration, it is necessary to strictly follow the steps and restart the BMC and the machine, which greatly increases the time cost; when encountering scenarios where the motherboard needs to be replaced frequently, on-site technicians are also required to check the model configuration used by the spare motherboard and replace it with the model configuration used by the customer's machine, which greatly increases the difficulty of operation for on-site personnel.

[0025] In view of the defects existing in the related technology, the embodiments of the present disclosure provide a baseboard management controller startup method, which aims to solve the problem of manual identification and switching of model configuration when replacing the mainboard, thereby simplifying the steps of model identification and switching, thereby achieving the purpose of improving generation efficiency and reducing the complexity of operations for technicians.

[0026] Figure 1 A first optional flow chart of a baseboard management controller startup method provided in an embodiment of the present disclosure is shown, and will be described according to each step.

[0027] Step S101 , in response to the initialization of a baseboard management controller, the number of fan presence signals of the electronic device is obtained.

[0028] In some embodiments, the baseboard management controller startup method is executed during the BMC startup process to complete the BMC startup for the electronic device model. In some embodiments, in response to BMC initialization, that is, the BMC starts to execute the startup program, the BMC obtains the number of fan in-place signals of the electronic device.

[0029] The number of fan-in-place signals of the electronic device includes the number of signals that are in a normal installation position on the motherboard of the electronic device (ie, the fan is connected to the correct slot / interface) and can be detected.

[0030] Step S102: determining the model of the electronic device based on the number of fan presence signals of the electronic device.

[0031] In some embodiments, different models of motherboards have different numbers of fan sockets. In order to ensure the normal operation of electronic equipment, different models of motherboards have different numbers of fans connected to them. The BMC can determine the number of fans connected to the motherboard based on the number of fan presence signals, and then determine the model of the electronic equipment based on the number of fans connected to the motherboard.

[0032] Step S103: determining the heat dissipation strategy of the electronic device, and the maximum number of slots and slot positions that can be connected to the hard disk backplane of the electronic device based on the model of the electronic device.

[0033] In some embodiments, determining the heat dissipation strategy of the electronic device during the BMC startup process can avoid the situation in which the CPU or other components are overheated due to an inappropriate heat dissipation strategy during the subsequent startup process of the electronic device.

[0034] In some embodiments, different models correspond to different cooling strategies and the maximum number of slots and slot positions that the hard disk backplane of the electronic device can connect to. The cooling strategy, maximum number of slots and slot positions of the electronic device can be determined based on the model of the electronic device determined in step S102.

[0035] Step S104, controlling fan heat dissipation based on the heat dissipation strategy of the electronic device, and performing preloading based on the maximum number of slots and slot positions that the hard disk backplane can connect to.

[0036] In some embodiments, after determining the heat dissipation strategy of the electronic device and the maximum number of slots and slot positions to which the hard disk backplane of the electronic device can be connected, fan heat dissipation can be controlled based on the heat dissipation strategy and preloading can be performed.

[0037] In some embodiments, when the BMC is started, it will preload according to a preset maximum number of slots and slot positions. In the prior art, if the actual maximum number of slots and slot positions of the electronic device are significantly different from the preset maximum number of slots and slot positions, manual settings are required and the BMC must be restarted so that the BMC can preload according to the actual maximum number of slots and slot positions. In the embodiments of the present disclosure, during the first startup phase of the BMC, the maximum number of slots and slot positions that the hard disk backplane of the electronic device can connect to (i.e., the actual maximum number of slots and slot positions of the electronic device) can be determined based on the electronic device model for preloading, thereby avoiding subsequent restarting of the BMC.

[0038] In this way, through the baseboard management controller startup method provided by the embodiment of the present disclosure, the model of the electronic device can be determined by the number of fans during the BMC startup process, and then the corresponding configuration can be preloaded according to the model of the electronic device to achieve BMC startup based on the electronic device without the need for subsequent restart, simplifying the operation and saving manpower and material resources.

[0039] Figure 2 A second optional flow chart of the baseboard management controller startup method provided in the embodiment of the present disclosure is shown, and will be explained according to each step.

[0040] Step S201, in response to BMC initialization, obtaining the number of fan presence signals of the electronic device.

[0041] Step S202: determining the model of the electronic device based on the number of fan presence signals of the electronic device.

[0042] Step S203: determining the heat dissipation strategy of the electronic device, and the maximum number of slots and slot positions that can be connected to the hard disk backplane of the electronic device based on the model of the electronic device.

[0043] Step S204, controlling fan heat dissipation based on the heat dissipation strategy of the electronic device, and performing preloading based on the maximum number of slots and slot positions that the hard disk backplane can connect to.

[0044] The specific step flow from step S201 to step S204 is the same as that from step S101 to step S104, and will not be repeated here.

[0045] Step S205: start the electronic device.

[0046] In some embodiments, after the BMC completes preloading, the electronic device starts, and the Inter-Integrated Circuit (i2C) signal is available, the BMC obtains the hard disk information connected to the hard disk backplane through the i2C; optionally, the hard disk information is displayed on a display screen corresponding to the electronic device. The hard disk information includes at least one of the number of hard disks, the working status of each hard disk, the model of the hard disk, the specification of the hard disk, the temperature of the hard disk, and the read and write speed of the hard disk.

[0047] In this way, through the baseboard management controller startup method provided by the embodiment of the present disclosure, the model of the electronic device can be determined by the number of fans during the BMC startup process, and then the corresponding configuration can be preloaded according to the model of the electronic device to achieve BMC startup based on the electronic device without the need for subsequent restart; after the BMC is started, the hard disk information connected to the hard disk backplane is obtained through i2C and displayed according to project requirements.

[0048] Figure 3 A third optional flow chart of the baseboard management controller startup method provided in the embodiment of the present disclosure is shown, and will be explained according to each step.

[0049] Step S301, obtaining the number of fan presence signals of the electronic device.

[0050] In some embodiments, different motherboards correspond to different machine models, and different machine models require different numbers of fans for heat dissipation. Therefore, the number of slots corresponding to fans on different motherboards is also different. When the motherboard is replaced, the number of fans connected to the motherboard will also change accordingly. Based on the number of connected fans, the model corresponding to the electronic device can be determined, and the number of connected fans can be determined by the fan presence signal.

[0051] In some embodiments, the BMC reads a first fan-in-place signal of an electronic device; in response to the number of the first fan-in-place signals being an even number, the BMC determines the number of the first fan-in-place signals as the number of fan-in-place signals of the electronic device; in response to the number of the first fan-in-place signals being an odd number, the fan-in-place signal of the electronic device is re-read.

[0052] Specifically, the number of fans corresponding to different models is usually an even number, and the probability of two or more faulty fans existing at the same time is very low. Therefore, whether the reading of the first fan presence signal is accurate can be determined based on the parity of the first fan presence signal. If it is an even number, it is determined that the reading of the first fan presence signal is accurate, and the number of the first fan presence signals is the number of fan presence signals of the electronic device; if it is an odd number, the reading of the first fan presence signal is inaccurate, or there is a problem during the reading process, or the fan is faulty, and it needs to be read again.

[0053] Specifically, when rereading, the BMC reads the second fan-in-place signal of the electronic device; in response to the number of the second fan-in-place signals being an even number, the number of the second fan-in-place signals is determined to be the number of fan-in-place signals of the electronic device; optionally, the BMC can set a preset threshold for rereading, and in response to the number of the second fan-in-place signals being an odd number, and the number of times the fan-in-place signals are reread is greater than or equal to the preset threshold, the number of the second fan-in-place signals plus 1 is determined to be the number of fan-in-place signals of the electronic device; in this way, subsequent operations, such as determining the model of the electronic device, can be entered in advance, without waiting for repeated confirmation of the number of fans or for the operation and maintenance personnel to troubleshoot the problem after an alarm, thereby improving the BMC startup efficiency.

[0054] Optionally, the BMC may also issue an alarm message, where the alarm message is used to indicate that there is a problem with the number of fans in place, so that the technician can promptly troubleshoot the hardware problem.

[0055] Step S302: determining the model of the electronic device based on the number of fan presence signals of the electronic device.

[0056] Step S303: determining the heat dissipation strategy of the electronic device, and the maximum number of slots and slot positions that can be connected to the hard disk backplane of the electronic device based on the model of the electronic device.

[0057] Step S304, controlling fan heat dissipation based on the heat dissipation strategy of the electronic device, and performing preloading based on the maximum number of slots and slot positions that the hard disk backplane can connect to.

[0058] The specific step flow from step S302 to step S304 is the same as that from step S102 to step S104, and will not be repeated here.

[0059] In this way, through the baseboard management controller startup method provided by the embodiment of the present invention, according to the characteristic that the number of fans in the current machine is usually an even number, a processing measure is added for identifying the signal of an odd number of fans in place. In order to prevent the problem of unstable signal, it will be re-read when an odd number of fans is detected. If an even number of fans higher than this number is read, it will be executed normally according to the number of fans in place. If no reading is done five times, it is preliminarily indicated that a fan is not installed or there is hardware damage to the mainboard. In order to allow the technicians to discover it in time, an alarm message is generated at this time, indicating that the number of fans is an odd number at this time. For the subsequent normal operation of the machine, the heat dissipation strategy is loaded according to the current odd number plus one model configuration to avoid overheating of the machine.

[0060] Figure 4 A fourth optional flow chart of the baseboard management controller startup method provided in the embodiment of the present disclosure is shown, and will be explained according to each step.

[0061] Step S401, obtaining the number of fan presence signals of the electronic device.

[0062] The specific step flow of step S401 is the same as step S101 or step S301, and will not be repeated here.

[0063] Step S402: determining the model of the electronic device based on the project information to which the electronic device belongs and the number of fan presence signals of the electronic device.

[0064] In some embodiments, different models correspond to different numbers of fans, for example, a 1-unit (1U) model is equipped with 2 to 4 fans, a 2U model is equipped with 3 to 6 fans, a 3-unit (3U) model is equipped with 3-6 fans, a 4U model is equipped with 3-8 fans, a 5-unit (5U) model is equipped with 6-8 fans, and a 6U model is equipped with more than 4 fans; the BMC can determine the model of the electronic device based on the number of fan in-position signals and the relationship between the number of fans and the model. The relationship between the number of fans and the model includes a table of relationships between different numbers of fans and corresponding models.

[0065] In some embodiments, in some actual projects, the 2U model is configured with 4 fans, the 4U model is configured with 6 or 8 fans, and the 6U model is configured with 8 or 12 fans; in different projects, the number of fans configured for each model is different and non-repetitive. For example, in a certain project, the 4U model is configured with 8 fans, then for the heat dissipation effect, the 6U model will be configured with a number of fans greater than 8, such as 12; or, in a certain project, the 4U model is configured with 6 fans, and the corresponding 6U model will be configured with 8 fans; therefore, the model can be determined based on the number of fans.

[0066] In some embodiments, the BMC can determine the project information corresponding to the electronic device; determine the relationship between the number of fans and the model based on the project information; and determine the model of the electronic device based on the relationship between the number of fans and the model and the number of fan in-position signals. The relationship between the number of fans and the model corresponding to different project information is different.

[0067] Step S403: determining the heat dissipation strategy of the electronic device, and the maximum number and positions of slots that can be connected to the hard disk backplane of the electronic device based on the model of the electronic device.

[0068] Step S404, controlling fan heat dissipation based on the heat dissipation strategy of the electronic device, and performing preloading based on the maximum number of slots and slot positions that the hard disk backplane can connect to.

[0069] The specific step flow from step S403 to step S404 is the same as that from step S103 to step S104, and will not be repeated here.

[0070] In this way, through the baseboard management controller startup method provided by the embodiment of the present disclosure, when determining the specific model, it can be directly based on the number of fan-in-place signals and the corresponding relationship between the number of fans and the model; it is also possible to first determine the project information corresponding to the electronic device, determine the corresponding relationship between the number of fans and the model based on the project information, and then determine the model of the electronic device in combination with the number of fan-in-place signals, thereby improving the accuracy of model determination.

[0071] Figure 5 A fifth optional flow chart of the baseboard management controller startup method provided in the embodiment of the present disclosure is shown, and will be explained according to each step.

[0072] Step S501, identifying the number of machine fan presence signals.

[0073] Step S501 is the same as step S101 or step S301 and will not be repeated here.

[0074] Step S502: determine the current model based on the identified number of fans in place.

[0075] In some embodiments, since different models use different numbers of fans, the number of fans can be used for judgment. At the same time, a trial and error mechanism is added. Since the number of fans of different models is usually an even number, when the in-place signal is an odd number, the signal is re-read. If five retries are still unsuccessful, an odd number of fans in place alarm is triggered, allowing on-site technicians to perceive it in time and troubleshoot hardware-related problems. At the same time, the machine model is judged by adding one to the fan in-place signal, and the corresponding fan strategy is loaded to avoid overheating of electronic equipment.

[0076] Step S503, loading a heat dissipation strategy based on the current model.

[0077] In some embodiments, the corresponding machine model is determined based on the number of fans identified in step S502 and the corresponding heat dissipation strategy is loaded.

[0078] Through steps S501 to S503, the current model of the electronic device is preliminarily determined and loaded into the corresponding heat dissipation strategy to avoid the situation where the CPU or other components of the electronic device are overheated due to an incorrect heat dissipation strategy during the startup process.

[0079] Step S504, pre-load the maximum number of slots and slot positions that can be connected to the hard disk backplane.

[0080] Among them, the maximum number of slots and slot positions that the hard disk backplane can connect to include the maximum number of slots and slot positions that the hard disk backplane can connect to. The "can" here means "can" or "can be able to", that is, it represents the capability of the hard disk backplane.

[0081] In some embodiments, when distinguishing different machine model configurations, BMC mainly focuses on some devices that need to be pre-loaded. Generally, the external cards of the machine, such as network cards, disk array cards (Redundant Array of Independent Disks Card, RAID), memory, etc., have fixed slots and do not require special attention. However, different models of hard disk backplanes often have differences in the available number and hard disk slots, and BMC mainly processes this part.

[0082] Step S505: BMC loading is completed and the electronic device starts.

[0083] In some embodiments, the BMC is fully started, all parts that need to be preloaded are processed, and the electronic device needs to be started to make i2c available before the subsequent steps can be performed.

[0084] Step S506: BMC reads the hard disk backplane information through i2C and displays it.

[0085] The hard disk backplane information includes hard disk information connected to the hard disk backplane.

[0086] In some embodiments, the BMC obtains the hard disk information in the backplane through i2c and displays it according to the requirements of the project; for example, the hard disk information includes the number of hard disks, the working status of each hard disk, the model of the hard disk, the specifications of the hard disk, the temperature of the hard disk and at least one of the read and write speed of the hard disk; the number of hard disks, the working status of each hard disk and the model of the hard disk are displayed according to the requirements of the project.

[0087] Thus, the baseboard management controller startup method provided by the embodiment of the present disclosure is aimed at the current electronic equipment production needs to strictly follow the steps to switch the scene and the customer site needs to replace the motherboard, the technical personnel need to manually identify the machine model and manually use the command to switch the operation scene; solve the problem of reducing the production line efficiency due to the model switching during production and the problem of complex and cumbersome manual operation at the customer site; improve the efficiency of production and customer site operation and greatly reduce the complexity of operation. And the BMC can identify the hardware problems of some machines in advance for the fan in-position signal and the backplane model. It should be noted that the BMC identification of the fan in-position signal and the operation of loading the machine model and configuration are completed during the BMC startup process. The previous and next steps are serially run during the code development process. Only when the code of the model module is executed, the corresponding configuration code is executed to avoid BMC abnormalities caused by disorder. In addition, the code can be modularized when developing, so that the project team does not need to consider too much when revising the plan at the beginning, and can add different models and configurations at any time according to market demand, greatly improving the flexibility of project operation.

[0088] Figure 6 An optional structural schematic diagram of a baseboard management controller startup device provided in an embodiment of the present disclosure is shown, and will be described according to each part.

[0089] In some embodiments, the baseboard management controller starting device 600 includes an acquiring unit 601 , a first determining unit 602 , a second determining unit 603 , and a preloading unit 604 .
