Description

Technical Field

[0001] The embodiments of the present application relate to the field of server technology, and in particular to a method and device for accessing a power supply unit, a storage medium, and an electronic device. Background Art

[0002] The power consumption of existing GPU servers is getting higher and higher, and the power consumption of the matching PSU modules is also getting higher and higher. The greater the power consumption, the greater the loss itself. Therefore, most AI GPU servers will use more efficient power supplies to meet the requirements of high efficiency and low loss.

[0003] However, although the server system switches the power module to Active-standby mode, the overall work efficiency can be improved. However, due to the dynamic current characteristics of the GPU itself, the current of the GPU itself will fluctuate greatly when processing business needs, which is usually called EDPp current. The greater the fluctuation of the GPU current, the greater the voltage fluctuation of its operation will be. With the development of GPUs, the voltage specifications of GPUs are currently required to be higher and higher. The higher the power consumption of the GPU, the higher the voltage fluctuation during operation. When the system switches the power module to Active-standby mode, the PSU current shared in each Active mode will increase, which will also affect the output voltage of the PSU, thereby causing the voltage on the GPU side to exceed the SPEC specification of the GPU, causing the GPU to drop the card, and in severe cases, it may cause the server to crash.

[0026] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] The method embodiments provided in the embodiments of the present application can be executed in a server device or a similar computing device. Taking running on a server device as an example, Figure 1 1 is a hardware structure block diagram of a server device of a method for accessing a power supply unit according to an embodiment of the present application. Figure 1 As shown, the server device may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the above-mentioned server device may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above server device. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0029] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the access method of the power supply unit in the embodiment of the present application. The processor 102 executes various functional applications and access to the power supply unit by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the server device via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0030] The transmission device 106 is used to receive or send data via a network.

In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0031] As an optional implementation, Figure 2 As shown, the access method of the power supply unit includes:

[0032] S202, respectively collecting current voltage values ​​of multiple image processing units in the server at the current moment;

[0033] S204, triggering a mode switching instruction when it is determined that the plurality of image processing units include the first processing unit according to a comparison result between the standard voltage values ​​corresponding to the plurality of image processing units and the current voltage value;

[0034] S206, according to the mode switching instruction, sequentially connect at least one power supply unit in the sleep mode to the power supply circuit for powering multiple image processing units until at least one circuit parameter corresponding to each of the multiple image processing units meets the target condition, wherein the power supply unit is used to convert AC current into DC current for powering multiple image processing units.

[0035] In an optional implementation, it should be noted that in the above step S202, the current voltage values ​​of multiple image processing units in the server at the current moment are respectively collected. It should be noted that a 12V voltage acquisition circuit can be added to the current power supply circuit, and the 12V voltage acquisition circuit can continuously monitor the voltage on the PCIE CONN (PCI Express connection) or other key interfaces to ensure that it remains within the specified range. The standard voltage value is determined based on the SPEC (specification) of the GPU and the operating requirements of the server, and is intended to ensure that the GPU operates within the established safety and performance range. In this implementation, the current voltage value of each GPU is collected, and the collected 12V voltage is compared with the SPEC specification. If the collected 12V voltage is within the SPEC, the power module maintains the current BMC setting and does not operate.

[0036] Furthermore, in the above step S204, when it is determined that the plurality of image processing units include the first processing unit according to the comparison result between the standard voltage values ​​corresponding to the plurality of image processing units and the current voltage value, the mode switching instruction is triggered.

[0037] Specifically, the comparison result may be that the current voltage value collected exceeds the standard voltage value, and the GPU is determined to be the first processing unit. The standard voltage value may be a voltage range or a specific value of the GPU operation determined according to the SPEC specification of the GPU. The mode switching operation instruction may be a mode switching operation sent after the voltage of the GPIO port is reversed, the BMC detects the voltage reversal, and determines that the GPU voltage exceeds the SPEC specification, which can be used to adjust the power supply state in the power supply circuit, such as switching at least one PSU in the Standby mode in the BMC switching circuit to the Active mode.

[0038] In some optional embodiments, such as step S206 above, according to the mode switching instruction, at least one power supply unit in the sleep mode is sequentially connected to the power supply circuit for powering multiple image processing units until at least one circuit parameter corresponding to each of the multiple image processing units meets the target condition, wherein the power supply unit is used to convert AC current into DC current for powering multiple image processing units.

[0039] The sleep mode may be a Standby mode, i.e., a standby state without being connected. The circuit parameters may be collected voltage, current, voltage fluctuation value, voltage fluctuation value, etc. The target condition may be that the parameter value of a circuit parameter of a certain attribute collected is less than the corresponding standard value.

[0040] As an optional implementation, Figure 3 As shown:

[0041] After booting up, first execute S302-1, the BMC collects the GPU model and sets the PCIE voltage SPEC; at the same time, execute S302, the BMC sets the PSU to enter Active-Standby mode.

[0042] Further executing S304, the PCIE CONN 12V circuit collects the 12V voltage;

[0043] According to the voltage value collected in step S304 and the standard voltage value determined according to the GPU model, it is determined in step S306 whether it exceeds the set value;

[0044] If the voltage does not exceed the standard voltage, continue to execute S304 to collect the voltage;

[0045] If the voltage exceeds the standard voltage, S308 is executed to switch one of the PSUs to the Active mode;

[0046] Further determine S310 whether it exceeds the set value; if it does not exceed the set value, end the control;

[0047] If the set value is exceeded, execute s312 to switch one of the PSUs to Active mode;

[0048] Further determine S314 whether it exceeds the set value, if not, end the control, if exceeded, return to execute S312.

[0049] Through the present application, first, the current voltage values ​​of multiple image processing units in the server at the current moment are collected respectively; when it is determined that the multiple image processing units include a first processing unit whose current voltage value exceeds the target working range based on the comparison results between the standard voltage values ​​corresponding to each of the multiple image processing units and the current voltage values, a mode switching instruction is triggered; thereby, according to the mode switching instruction, at least one power supply unit in the sleep mode is sequentially connected to the power supply circuit for powering the multiple image processing units until at least one circuit parameter corresponding to each of the multiple image processing units meets the target condition, and the image processing units in the circuit are put into a normal working state according to the above-mentioned power supply adjustment strategy. Through this method, the server can dynamically adjust the working state of the power supply unit according to the actual needs of the image processing unit, effectively avoiding the problem of insufficient or excessive power supply, improving the operating efficiency and energy utilization efficiency of the server, and solving the technical problems of poor effect of adjusting the power supply strategy and low safety in the related technology.

[0050] In an optional implementation, when it is determined that the plurality of image processing units include the first processing unit according to the comparison results between the standard voltage values ​​corresponding to the plurality of image processing units and the current voltage values, the triggering mode switching instruction includes:

[0051] S1, in the case where there is a first processing unit whose comparison result between the current voltage value and the standard voltage value matching the current voltage value is greater than a first threshold value and whose comparison result is less than or equal to a second threshold value, obtaining current description information matching the first processing unit, wherein the first threshold value is less than the second threshold value;

[0052] S2, determining a trigger mode switching instruction when the current description information indicates that the current trend matching the first processing unit satisfies the mode switching condition;

[0053] s3, in the case where there is a first processing unit whose comparison result between the current voltage value and the standard voltage value matching it is greater than the second threshold, determining a trigger mode switching instruction.

[0054] Optionally, in this embodiment, S1-S2 are first executed. When there is a first processing unit in which the comparison result between the current voltage value and the standard voltage value matching it is greater than a first threshold and the comparison result is less than or equal to a second threshold, the current description information matching the first processing unit is obtained, wherein the first threshold is less than the second threshold; when the current description information indicates that the current trend matching the first processing unit satisfies the mode switching condition, a trigger mode switching instruction is determined.

[0055] Optionally, the comparison result may specifically be a ratio of the current voltage value to the standard voltage value, or a ratio of the current voltage value to the standard voltage value, etc. The first threshold value and the second threshold value may be dynamically set according to the running state of the server, for example, the first threshold value may be set to ±3% of the standard voltage value (SPEC voltage) range, and the second threshold value may be set to ±6% of the standard voltage value (SPEC voltage) range, that is, the current value exceeds ±3% of the standard voltage value range, and the current description information is obtained when the current value is within ±3% of the standard voltage value range; the current description information may be, but is not limited to, information such as the current value, the current trend, and the current fluctuation state; the mode switching condition may be, but is not limited to, the current reaching the maximum value of the GPU standard specification current, and the current fluctuation trend in the recent time period is drastic, or the load change rate is greater than a preset value, etc., and no specific restrictions are made here; the mode switching instruction may be, but is not limited to, an instruction issued in the form of a digital signal, a network protocol signal, or a PWM signal to switch the power supply in the sleep mode to the working mode, that is, to connect the power supply unit in the standby state to the power supply circuit.

[0056] It should be noted that when the GPU load changes, the BMC will automatically adjust the first threshold according to the current state and trend of the load. For example, if the load is low, the BMC may relax the threshold and allow a larger voltage fluctuation range to reduce the switching of the PSU and save energy. If the load is high and unstable, the BMC will tighten the threshold to ensure that the voltage changes within a smaller range, avoid the GPU voltage exceeding the SPEC, and ensure system stability.

[0057] As an optional implementation, the level 1 alarm setting voltage is set close to the upper and lower limits of the GPU voltage SPEC. After the server is turned on, the BMC, GPU, and other components start working, and the PCIE voltage acquisition circuit also starts working. The collected 12V voltage is compared with the level 1 alarm point. If the collected 12V voltage is within the SPEC, the power module maintains the current BMC setting and does not act. If the collected 12V voltage exceeds the level 1 alarm range, the system collects and feeds back the current value of the GPU to determine whether the current of the GPU reaches the maximum value at this time. If the current of the GPU reaches the maximum value at this time, the system BMC does not issue an alarm, and the system processes the business normally. If the current of the GPU does not reach the maximum value at this time, the system BMC determines whether the next working current of the GPU will rise or fall based on the current trend fed back by the current sampling circuit. If it is determined that the current continues to rise or fall, the BMC switches one of the PSUs in the Standby mode to the Active mode to reduce the current fluctuation of the entire PSU, thereby reducing the working voltage fluctuation range of the 1 2V link of the entire system. If it is determined that the GPU current trend is stable and remains unchanged at this time, the system BMC will not issue an alarm and the system will process business normally.

[0058] Further in the above step S3, in the case that there is a first processing unit whose comparison result between the current voltage value and the standard voltage value matching it is greater than the second threshold, a trigger mode switching instruction is determined.

[0059] As an optional implementation, the voltage of the second-level alarm setting exceeds the upper and lower limits of the GPU voltage SPEC. When the 12V voltage collected and fed back by the PCIE voltage acquisition circuit triggers the second-level alarm, the voltage of the GPIO port is immediately reversed. After the BMC detects the voltage reversal, it determines that the GPU voltage exceeds the SPEC specification. The BMC sends an instruction to one of the standby power modules to switch the Standby mode to the Active mode. After the switch is successful, the PCIE voltage acquisition circuit continues to feedback 12V voltage. If the alarm is still triggered, the other Standby mode power modules continue to switch to the Active mode until the 12V voltage fed back by the acquisition circuit is within the GPU SPEC specification. After the GPU voltage meets the SPEC, the voltage of the GPIO port is restored. After the power module in the Standby mode is successfully switched to the Active mode, the PCIE voltage acquisition circuit continues to feedback 12V voltage. If the alarm is not triggered, the voltage of the GPIO port is restored. At this time, the first-level alarm judgment continues to be performed, and the first-level alarm judgment process is entered. Until the GPU meets the specifications, it can work stably. If the voltage at the GPU end still exceeds the SPEC operating voltage range after all power modules are switched to Active, the system can use the BMC to adjust the CPU operating frequency or GPU operating frequency to limit the power consumption current of the GPU to ensure that the GPU does not exceed the SPEC.

[0060] Through the above implementation of the present application, in the case of a first processing unit where the comparison result between the current voltage value and the standard voltage value matching it is greater than the first threshold value, and the comparison result is less than or equal to the second threshold value, the current description information matching the first processing unit is obtained; in the case where the current description information indicates that the current trend matching the first processing unit meets the mode switching condition, the trigger mode switching instruction is determined; in the case of a first processing unit where the comparison result between the current voltage value and the standard voltage value matching it is greater than the second threshold value, the trigger mode switching instruction is determined; by setting different thresholds to distinguish the access timing of the power supply unit, the working state of the power supply unit can be controlled more finely, and the voltage demand changes of the image processing unit under different loads can be effectively responded to, ensuring that the server can operate stably under various working conditions. The response speed and processing capacity of the server are improved, while reducing the system failure rate caused by voltage fluctuations.

[0061] In an optional implementation, when the current description information indicates that the current trend matching the first processing unit satisfies the mode switching condition, determining a trigger mode switching instruction includes:

[0062] S1, acquiring multiple current values ​​matching the first processing unit within a target acquisition cycle, and determining a current trend matching the first processing unit according to the multiple current values, wherein the last acquisition moment of the target acquisition cycle is the current moment;

[0063] S2, when the current description information indicates that the current value collected at the current moment is the standard maximum current value and the current trend is an upward or downward trend, determine that the mode switching condition is met and trigger a mode switching instruction.

[0064] In the above steps S1-s2, multiple current values ​​matching the first processing unit within the target acquisition cycle are obtained, and the current trend matching the first processing unit is determined based on the multiple current values, wherein the last acquisition moment of the target acquisition cycle is the current moment; when the current description information indicates that the current value collected at the current moment is the standard maximum current value, and the current trend is an upward or downward trend, it is determined that the mode switching condition is met and the mode switching instruction is triggered. The above target acquisition cycle is a preset time interval for collecting data in a data acquisition system in order to meet specific monitoring, analysis or control requirements. The acquisition cycle can be optimized in real time according to factors such as the current load state, system operating environment or health status of the power module.

[0065] The following Figure 4 The control flow is shown as an example:

[0066] After the computer is turned on, S402 is executed, and the BMC collects information such as the GPU model and power consumption; specifically, it reads key information such as the GPU model, power consumption characteristics, and voltage specifications.

[0067] S404, set a first-level alarm value; and further determine the current collected voltage and the standard voltage, determine S406, whether to issue a first alarm value; for example, it can be near the upper and lower limits of the GPU voltage specification, such as a point between 11.4V and 12.6V.

[0068] If the first alarm value is issued, S408 is executed to collect GPU current data; further judgment is made in S410 to determine whether the GPU rated value is reached; if the GPU rated value is not reached, S412 is executed and the system does not issue an alarm; and control ends.

[0069] That is, the 12V voltage acquisition circuit starts working and monitors the voltage of the PCIE CONN terminal in real time. The BMC receives these voltage data and compares them with the first-level alarm value. If the current voltage is within the alarm value, that is, the GPU has room to handle more load, the system will not send an alarm, but continue to monitor, and the BMC will not take any action.

[0070] If the GPU rated value is reached, S414 is executed to determine the GPU current trend;

[0071] Further judgement of S416, current rise?

[0072] If the current increases, S418 is executed to switch one of the PSUs into Active mode, which is used to distribute the load, reduce voltage fluctuations, and prevent the GPU voltage from exceeding SPEC.

[0073] If the current does not increase, that is, the current trend is gentle and the circuit fluctuation in the power supply circuit is small, the BMC maintains the current PSU state to execute S420, and the GPU voltage is maintained within SPEC.

[0074] Through the above-mentioned implementation mode of the present application, multiple current values ​​matching the first processing unit within the target acquisition period are obtained, and the current trend matching the first processing unit is determined based on the multiple current values; when the current description information indicates that the current value collected at the current moment is the standard maximum current value, and the current trend is an upward or downward trend, it is determined that the mode switching condition is met and the mode switching instruction is triggered. By analyzing the current trend, the power consumption change of the image processing unit is predicted, and the working state of the power supply unit is adjusted, thereby avoiding the problem of insufficient power supply due to a sudden increase in power consumption, improving the power supply stability and prediction ability of the server, and solving the problems of low efficiency and low safety of the power supply strategy in the prior art.

[0075] In an optional implementation, when there is a first processing unit whose comparison result between the current voltage value and the standard voltage value matching the current voltage value is greater than the second threshold, determining the trigger mode switching instruction further includes:

[0076] S1, reverse the voltage of the detection port in the power supply circuit and send a second alarm message;

[0077] s2, connecting at least one power supply unit in the sleep mode to the power supply circuit in sequence according to the second alarm information, until the comparison result between the current voltage value of each first processing unit and the standard voltage value matching it is less than or equal to the second threshold;

[0078] S3, when a comparison result between the current voltage value of the first processing unit and the standard voltage value matching the first processing unit is greater than a first threshold, obtaining current description information matching the first processing unit;

[0079] S4, sending a first alarm message when the current description information indicates that the current trend matching the first processing unit is an upward or downward trend;

[0080] s5. Connect at least one power supply unit in the sleep mode to the power supply circuit in sequence according to the first alarm information until the comparison result between the current voltage value of each image processing unit and the standard voltage value matching it is less than or equal to the first threshold.

[0081] Optional, with flow chart Figure 5 The above steps s1-s5 are explained as follows:

[0082] After booting, execute S502, and the BMC collects information such as GPU model and power consumption; S504 sets the second-level alarm value;

[0083] Further determine S506 whether the GPU is pressurized to trigger the second level alarm value; if the second level alarm value is not triggered, continue to determine the state at the next moment.

[0084] If the second level alarm value is triggered, S508 is executed, the voltage of the GPIO port is immediately reversed, and a mode switching signal is sent to the BMC; further, the BMC executes S510 to switch one of the PSUs into the Active mode.

[0085] After the mode is switched, it is continued to determine in S512 whether the second level alarm value is triggered; if the second level alarm value is triggered, S514 is executed to continue switching one of the PSUs to enter the Active mode; S516, the voltage of the GPIO port is restored to the reset position.

[0086] On the other hand, if the second-level alarm value is not triggered after the mode switching, the first-level alarm processing flow is performed, S518 is executed, and the voltage of the GPIO port is restored to the reset position; further judgment S520 is made to see whether the first-level alarm value is triggered; if the first-level alarm value is not triggered, the process ends.

[0087] If the first level alarm value is triggered, S522 is executed to jump to the first level alarm processing flow, such as Figure 4 As shown; the schematic diagram of the above overall switching process is as shown Figure 6 As shown, the 12V voltage sampling in the circuit determines whether it is within the standard voltage value range, and further increases the 12V current sampling. If the acquisition voltage value of the GPU in the circuit is determined to exceed the standard voltage value according to the above process, and the circuit state fluctuates, the GPIO port is reversed, and the BMC module controls the PSU unit to switch the mode, or when the acquisition voltage value does not exceed the standard voltage value, the GPIO port is restored.

[0088] Through the above-mentioned implementation steps of the present application, a multi-level alarm mechanism is set up, which can respond to power supply abnormalities in a timely manner, avoid hardware damage caused by excessively high or low voltage, and improve the reliability and safety of the server.

[0089] In an optional implementation, after determining the trigger mode switching instruction, the method includes:

[0090] S1, obtaining a current fluctuation coefficient matching the power supply circuit at the current moment, wherein the current fluctuation coefficient is used to indicate the degree of current fluctuation, and the degree of current fluctuation is negatively correlated with the number of power supply units;

[0091] S2, when the ratio of the current fluctuation coefficient to the target adjustment coefficient is in the first reference interval, determining that the current fluctuation degree of the power supply circuit at the current moment is in a slight fluctuation state, wherein the target adjustment coefficient is an average value of multiple current fluctuation coefficients matching multiple power supply circuits in the target performance state;

[0092] s3, determining that the number of power supply units that need to perform mode switching operations matching the slight fluctuation state is a first number, and sequentially connecting the first number of power supply units to the power supply circuit;

[0093] s4, when the ratio of the current fluctuation coefficient to the target adjustment coefficient is within the second reference interval, determining that the current fluctuation degree of the power supply circuit at the current moment is in a severe fluctuation state;

[0094] s5, determining that the number of power supply units that need to perform mode switching operations matching the violent fluctuation state is a second number, and sequentially connecting the second number of power supply units to the power supply circuit.

[0095] In the above steps S1-S3, first, a current fluctuation coefficient matching the power supply circuit at the current moment is obtained; then, when the ratio of the current fluctuation coefficient to the target adjustment coefficient is in the first reference interval, it is determined that the current fluctuation degree of the power supply circuit at the current moment is a slight fluctuation state; it is further determined that the number of power supply units that need to perform mode switching operations matching the slight fluctuation state is a first number, and the first number of power supply units are connected to the power supply circuit in sequence.

[0096] Optionally, the current fluctuation coefficient can be calculated based on the highest and lowest current values ​​in the past 10 seconds, and the ratio of the difference between the two to the average value of the historical fluctuation coefficient, so as to quantify the current current fluctuation degree. For example, if the current variation range in 10 seconds is 10A and the average current is 100A, then the current fluctuation coefficient is 10%. The target performance state can be the optimal or normal working state expected by the server or power system when it is designed, including the performance of the system when processing a specific workload, or the state of operation under a certain power consumption and efficiency, etc.;

[0097] The above target adjustment coefficient can be that the current fluctuation coefficients monitored under normal processing of workload at historical moments are 8%, 9%, 10%, 11%...18%, and the average value of these coefficients (for example, 13%) can be used as the target adjustment coefficient. This means that when the system is operating normally, the average amplitude of the current fluctuation is about 13%.

[0098] In some optional embodiments, when the ratio of the current current fluctuation coefficient to the target adjustment coefficient is between 0.8-1.2, it is determined that the current circuit is in a slight fluctuation state, and the range of the number of PSUs that need to be connected to the power supply circuit in the slight fluctuation state can be determined in advance through a machine learning algorithm. For example, in the slight fluctuation state, three new PSUs need to be connected, that is, the modes of the three PSUs are switched, and the Standby mode is switched to the Active mode. It can be understood that the modes can be switched sequentially while checking the fluctuation state of the circuit, or all of them can be connected at once, and no specific restrictions are made here.

[0099] In the above steps S4-S5, when the ratio of the current fluctuation coefficient to the target adjustment coefficient is in the second reference interval, it is determined that the current fluctuation degree of the power supply circuit at the current moment is a severe fluctuation state; the number of power supply units that need to perform mode switching operations to match the severe fluctuation state is determined to be the second number, and the second number of power supply units are connected to the power supply circuit in sequence.

[0100] The following is an explanation of an optional implementation method, assuming that a server system has 8 PSUs, 4 of which are in Active state and 4 in Standby state. The target adjustment coefficient of the system design is 5%, which means that during normal operation, the acceptable current fluctuation range is ±5% of the average current value. If the monitored current fluctuation coefficient is 3%, and the ratio to the target adjustment coefficient is in the first reference interval, the system determines that it is in a slight fluctuation state. In this case, the system decides to switch only 2 PSUs into Active state to increase redundancy, but will not significantly increase power consumption.

[0101] If the current fluctuation coefficient suddenly increases to 10% and the ratio is in the second reference interval, the system determines that it is in a violent fluctuation state. In order to quickly stabilize the current, the system may decide to switch 4 PSUs into the Active state at the same time to improve the stability and redundancy of the current supply.

[0102] Through the above-mentioned implementation method recorded in this application, that is, the intelligent algorithm based on the ratio of the current fluctuation coefficient to the target coefficient, the number of new PSU modules that need to be connected in the power supply strategy can be dynamically predicted in advance, so that the server power management system can achieve more efficient, more stable and safer power supply in a complex and changeable working environment, and improve the efficiency of the power supply strategy.

[0103] In an optional implementation, at least one power supply unit in the sleep mode is sequentially connected to the power supply circuit according to the first alarm information until a comparison result between a current voltage value of each image processing unit and a standard voltage value matched therewith is less than or equal to a first threshold value, including:

[0104] s 1, when all power supply units are in working mode and the comparison result between the current voltage value of the first processing unit and the standard voltage value matching it is greater than the first threshold value, perform a power consumption limiting operation on the first processing unit until the comparison result between the current voltage value of each image processing unit in the server and the standard voltage value matching it is less than or equal to the first threshold value, wherein the power consumption limiting operation is used to adjust the working frequency of the image processing unit to reduce the power consumption current of the image processing unit.

[0105] Optionally, if the voltage at the GPU end still exceeds the SPEC operating voltage range after all power modules are switched to Active, the system can use BMC to adjust the GPU operating frequency and limit the power consumption current of the GPU to ensure that the GPU does not exceed SPEC. Specifically, it includes but is not limited to adjusting the clock speed and core voltage of the GPU or limiting its maximum power consumption, thereby reducing the power consumption of the GPU and allowing the voltage to drop naturally until it reaches a safe range.

[0106] Through the above implementation of the present application, when all power supply units are in working mode and the comparison result between the current voltage value of the first processing unit and the standard voltage value matching it is greater than the first threshold value, the power consumption limiting operation is performed on the first processing unit until the comparison result between the current voltage value of each image processing unit in the server and the standard voltage value matching it is less than or equal to the first threshold value; by limiting the power consumption of the image processing unit when the power supply unit is working at full load, the system crash caused by insufficient power supply capacity is avoided, and the fault tolerance and emergency response capabilities of the server are improved. It can ensure that the server can still maintain basic operation under limited power supply conditions, reducing the risk of business interruption.

[0107] Through this dynamic adjustment mechanism, the server's power management system can intelligently respond to voltage fluctuations caused by high-power components (such as GPUs) and ensure the stability and efficiency of the system when processing complex workloads by performing power consumption limitation operations in a timely manner. At the same time, it protects key hardware from damage caused by voltage anomalies, thereby improving the overall operation quality and service life of the server.
