Description

Technical Field

[0001] This application relates to the field of server technology, and more specifically, to a power supply unit access method and apparatus, storage medium and electronic device. Background Technology

[0002] Existing GPU servers are consuming increasingly higher power, and the power consumption of the accompanying PSU modules is also increasing. The higher the power consumption, the greater the losses themselves. Therefore, most AI GPU servers will use more efficient power supplies to meet the requirements of high efficiency and low loss.

[0003] However, while switching the power module to Active-standby mode can improve overall efficiency, the dynamic current characteristics of the GPU mean that its current fluctuates significantly when processing workloads, a phenomenon commonly referred to as EDPp current. The greater the GPU current fluctuation, the greater the voltage variation. With the advancement of GPUs, voltage specifications are becoming increasingly stringent. Higher power consumption GPUs exhibit greater voltage fluctuations during operation. Switching the power module to Active-standby mode increases the current distributed across each PSU in Active mode, affecting the PSU's output voltage and potentially causing the GPU voltage to exceed its specifications. This can lead to GPU failure and, in severe cases, server crashes. In other words, adjusting power supply strategies in related technologies often results in poor effectiveness and low security.

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

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

[0028] The methods and embodiments provided in this application can be executed on a server device or a similar computing device. Taking running on a server device as an example, Figure 1 This is a hardware structure block diagram of a server device for a power supply unit access method according to an embodiment of this application. For example... Figure 1 As shown, the server device may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The server device may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that… Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the server equipment described above. For example, the server equipment may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0029] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the power supply unit access method in this embodiment. The processor 102 executes various functional applications and accesses the power supply unit by running the computer program stored in the memory 104, thus implementing the above-described method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to server devices via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0030] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider for the server device. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0031] As an optional implementation method, such as Figure 2 As shown, the connection method of the above power supply unit includes:

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

[0033] S204, if it is determined that the first processing unit is included among the multiple image processing units based on the comparison result between the standard voltage value and the current voltage value corresponding to each of the multiple image processing units, a mode switching instruction is triggered.

[0034] S206, 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 the AC current into the DC current for powering the multiple image processing units.

[0035] In an optional implementation, it should be noted that in step S202 above, the current voltage values ​​of multiple image processing units in the server are collected at the current moment. It should be noted that a 12V voltage acquisition circuit can be added to the current power supply circuit. This 12V voltage acquisition circuit can continuously monitor the voltage on the PCIe CONN (PCI Express connection) or other critical interfaces to ensure that it remains within a specified range. The standard voltage value is determined according to the GPU's SPEC (specification) and the server's operating requirements, aiming to ensure that the GPU operates within a predetermined 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 step S204 above, if it is determined that the first processing unit is included among the multiple image processing units based on the comparison result between the standard voltage value corresponding to each of the multiple image processing units and the current voltage value, a mode switching command is triggered.

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

[0038] In some optional implementations, 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. The power supply unit is used to convert the AC current into the DC current for powering the multiple image processing units.

[0039] The aforementioned sleep mode can be Standby mode, i.e., a standby state when not connected. The aforementioned circuit parameters can be the collected voltage, current, voltage fluctuation value, etc. The aforementioned target condition can be that the parameter value of a certain attribute of the collected circuit parameter is less than the corresponding standard value.

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

[0041] After powering on, first execute S302-1, where the BMC collects the GPU model and sets the PCIE voltage SPEC; simultaneously execute S302, where the BMC sets the PSU to enter Active-Standby mode.

[0042] Further execution of S304, PCIE CONN 12V circuit to acquire 12V voltage;

[0043] Based on the voltage value collected in step S304 and the standard voltage value determined according to the GPU model, determine in step S306 whether the set value is exceeded.

[0044] If the voltage does not exceed the standard voltage, continue executing S304 to collect the voltage.

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

[0046] Further check S310 to see if 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 whether S314 exceeds the set value. If it does not exceed the set value, end the control. If it does exceed the set value, return to execute S312.

[0049] This application first collects the current voltage values ​​of multiple image processing units in the server at the current moment. Based on the comparison between the standard voltage value and the current voltage value of each image processing unit, if a first processing unit is identified whose current voltage value exceeds the target operating range, a mode switching command is triggered. Then, according to the mode switching command, at least one power supply unit in 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 image processing unit meets the target conditions. Based on the aforementioned power supply adjustment strategy, the image processing units in the circuit are brought into normal operation. Through this method, the server can dynamically adjust the operating state of the power supply units according to the actual needs of the image processing units, effectively avoiding insufficient or excessive power supply, improving the server's operating efficiency and energy utilization efficiency, and solving the technical problems of poor effectiveness and low security in related technologies regarding power supply adjustment strategies.

[0050] In one optional implementation, if it is determined that the first processing unit is included among the multiple image processing units based on the comparison result between the standard voltage value corresponding to each of the multiple image processing units and the current voltage value, a mode switching instruction is triggered, including:

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

[0052] S2, if the current description information indicates that the current trend matching the first processing unit meets the mode switching conditions, determine to trigger the mode switching command.

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

[0054] Optionally, in this embodiment, S1-S2 are executed first. If there is a first processing unit where the comparison result between the current voltage value and the matching standard voltage value is greater than a first threshold and the comparison result is less than or equal to a second threshold, current description information matching the first processing unit is obtained, wherein the first threshold is less than the second threshold. If the current description information indicates that the current trend matching the first processing unit meets the mode switching conditions, a mode switching command is determined to be triggered.

[0055] Optionally, the comparison result can specifically be the ratio of the current voltage value to the standard voltage value, or the ratio of the current voltage value to the standard voltage value, etc. The first threshold and the second threshold can be dynamically set according to the server's operating status. For example, the first threshold can be set to ±3% of the standard voltage value (SPEC voltage) range, and the second threshold can be set to ±6% of the standard voltage value (SPEC voltage) range. That is, if the current voltage value exceeds the standard voltage value range by ±3% and is within ±3% of the standard voltage value range, the current description information is obtained. The current description information can be, but is not limited to, current value, current trend, current fluctuation status, etc. The mode switching condition can be, but is not limited to, the current reaching the maximum current value of the GPU standard specification, and the current fluctuation trend being drastic in the recent time period, or the load change rate being greater than a preset value, etc., without specific restrictions. The mode switching instruction can be, but is not limited to, an instruction issued in the form of digital signals, network protocol signals, or PWM signals to switch the power supply in sleep mode to working mode, that is, to connect the power supply unit in standby mode to the power supply circuit.

[0056] It's important to note that when the GPU load changes, the BMC automatically adjusts the first threshold based on the current state and trend of the load. For example, if the load is low, the BMC may loosen the threshold, allowing for a larger voltage fluctuation range to reduce PSU switching and save energy. If the load is high and unstable, the BMC will tighten the threshold to ensure that voltage changes are within a smaller range, preventing the GPU voltage from exceeding the SPEC and ensuring 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 powers on, components such as the BMC and GPU begin operating, and the PCIe voltage acquisition circuit also starts working. The acquired 12V voltage is compared with the Level 1 alarm point. If the acquired 12V voltage is within the SPEC, the power module maintains the current BMC setting and does not activate. If the acquired 12V voltage exceeds the Level 1 alarm range, the system collects and feeds back the GPU current value to determine if the GPU current has reached its maximum value. If the GPU current has reached its maximum value, the system BMC does not issue an alarm, and the system processes services normally. If the GPU current has not reached its maximum value, the system BMC determines whether the GPU's operating current will increase or decrease based on the current trend fed back by the current sampling circuit. If it determines that the current will continue to increase or decrease, the BMC switches one of the PSUs in Standby mode to Active mode to reduce the overall PSU current fluctuation, thereby reducing the operating voltage fluctuation range of the entire system's 12V link. If the GPU current trend is determined to be flat and unchanged at this time, the system BMC will not issue an alarm, and the system will process the business normally.

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

[0059] As an optional implementation, the Level 2 alarm is set when the voltage exceeds the upper or lower limits of the GPU voltage specification. When the 12V voltage collected by the PCIe voltage acquisition circuit triggers the Level 2 alarm, the voltage on the GPIO port is immediately reversed and set. The BMC detects the voltage reversal and determines that the GPU voltage exceeds the specification. The BMC then sends a command to one of the standby power modules to switch from Standby mode to Active mode. After a successful switch, the PCIe voltage acquisition circuit continues to collect the 12V voltage. If an alarm is still triggered, other standby power modules are switched to Active mode until the 12V voltage collected by the acquisition circuit is within the GPU specification. Once the GPU voltage meets the specification, the GPIO port voltage is reset. After successfully switching a power module from Standby mode to Active mode, the PCIe voltage acquisition circuit continues to collect the 12V voltage. If no alarm is triggered, the GPIO port voltage is reset. At this point, the Level 1 alarm determination process continues, entering the Level 1 alarm determination procedure. This continues until the GPU can operate stably while meeting the specifications. If the GPU voltage 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 or GPU operating frequency to limit the GPU's power consumption and current, ensuring that the GPU does not exceed the SPEC.

[0060] Through the above-described embodiments of this application, when a first processing unit exists where the comparison result between the current voltage value and its matching standard voltage value is greater than a first threshold and the comparison result is less than or equal to a second threshold, current description information matching the first processing unit is obtained; when the current description information indicates that the current trend matching the first processing unit meets the mode switching conditions, a mode switching command is determined; when a first processing unit exists where the comparison result between the current voltage value and its matching standard voltage value is greater than the second threshold, a mode switching command 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 precisely, effectively responding to changes in the voltage demand of the image processing unit under different loads, ensuring stable operation of the server under various working conditions. This improves the server's response speed and processing capacity while reducing the system failure rate caused by voltage fluctuations.

[0061] In one optional implementation, if the current description information indicates that the current trend matching the first processing unit satisfies the mode switching condition, a mode switching command is determined to be triggered, including:

[0062] S1, acquire multiple current values ​​that match the first processing unit within the target acquisition period, and determine the current trend that matches the first processing unit based on the multiple current values, wherein the last acquisition time of the target acquisition period is the current time;

[0063] S2, if the current value collected at the current moment indicates that the current value is the standard maximum current value and the current trend is upward or downward, determine that the mode switching condition is met and trigger the mode switching command.

[0064] In steps S1-s2 above, multiple current values ​​matching the first processing unit within the target acquisition period are acquired, and the current trend matching the first processing unit is determined based on these multiple current values. The last acquisition moment of the target acquisition period is the current moment. If the current value acquired at the current moment indicates that the current value is the standard maximum current value, and the current trend is either increasing or decreasing, the mode switching condition is met, and a mode switching command is triggered. The aforementioned target acquisition period is a preset time interval for acquiring data in the data acquisition system to meet specific monitoring, analysis, or control needs. The acquisition period can be optimized in real time based on factors such as the current load status, system operating environment, or the health status of the power module.

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

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

[0067] S404 sets the first-level alarm value; and further determines whether the currently collected voltage is equal to the standard voltage, and determines S406 whether to issue the first alarm value; for example, it can be near the upper or lower limit of the GPU voltage specification, such as a point between 11.4V and 12.6V.

[0068] If the first alarm value is issued, execute S408 to collect GPU current data; further determine S410 whether the GPU rated value has been reached; if the GPU rated value has not been reached, execute S412, the system will not issue an alarm; end control.

[0069] The 12V voltage acquisition circuit starts working, monitoring the voltage at the PCIe CONN pin in real time. The BMC receives this voltage data and compares it with the first-level alarm value. If the current voltage is within the alarm value, meaning the GPU has room to handle more load, the system will not send an alarm but will continue monitoring, and the BMC will not take any action.

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

[0071] Further analysis of S416 reveals an increase in current.

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

[0073] If the current does not increase, that is, the current trend is flat and the circuit fluctuations within the power supply circuit are small, then the BMC maintains the current PSU state and executes S420, and the GPU voltage remains within the SPEC.

[0074] Through the above-described embodiments of this 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 acquired 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 a mode switching command 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. This avoids the problem of insufficient power supply caused by a sudden increase in power consumption, improves the power supply stability and predictive ability of the server, and thus solves the problems of low efficiency and low security of the existing power supply strategy.

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

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

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

[0078] S3, if the comparison result between the current voltage value of the first processing unit and the standard voltage value that matches it is greater than the first threshold, obtain the current description information that matches the first processing unit;

[0079] S4, if the current description information indicates that the current trend matching the first processing unit is an upward or downward trend, send the first alarm information;

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

[0081] Optional, flowchart Figure 5 The following explanation is provided for steps s1-s5 above:

[0082] After powering on, execute S502, where the BMC collects information such as GPU model and power consumption; execute S504, where the secondary alarm value is set.

[0083] Further determine whether the second-level alarm value is triggered after the S506 GPU is pressured; if the second-level alarm value is not triggered, continue to determine the status at the next moment.

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

[0085] After the mode switch, continue to check S512 to see if the second-level alarm value is triggered; if the second-level alarm value is triggered, execute S514 to switch one of the PSUs into Active mode; in S516, the voltage of the GPIO port is reset.

[0086] On the other hand, if the second-level alarm value is not triggered after the mode switch, the first-level alarm processing procedure is performed, executing S518 to restore the voltage of the GPIO port to the set position; further determining S520 to see if 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, execute S522 to jump to the first-level alarm handling process, such as... Figure 4 As shown; a schematic diagram of the overall switching process described above is shown below. Figure 6 As shown, the circuit samples the 12V voltage to determine if it is within the standard voltage range. Then, it further samples the 12V current. If, based on the above process, the GPU's collected voltage value exceeds the standard voltage value and the circuit state fluctuates, the GPIO port is reverse-set, and the BMC module controls the PSU unit to switch modes. Alternatively, if the collected voltage value does not exceed the standard voltage value, the GPIO port is reset.

[0088] By implementing the steps outlined in this application, a multi-level alarm mechanism is established, enabling timely response to power supply anomalies and preventing hardware damage caused by excessively high or low voltage, thereby improving the reliability and security of the server.

[0089] In one alternative implementation, after determining the trigger mode switching instruction, the process includes:

[0090] S1, obtain the current fluctuation coefficient that matches 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 within the first reference range, the current fluctuation of the power supply circuit at the current moment is determined to be a slight fluctuation state, wherein the target adjustment coefficient is the average value of multiple current fluctuation coefficients matched with multiple power supply circuits in the target performance state.

[0092] s3, determine the number of power supply units that need to perform mode switching operation to match the slight fluctuation state as the first number, and connect the first number of power supply units to the power supply circuit in sequence;

[0093] s4, when the ratio of the current fluctuation coefficient to the target adjustment coefficient is in the second reference range, the current fluctuation of the power supply circuit at the current moment is determined to be a severe fluctuation state.

[0094] s5, determine the number of power supply units that need to perform mode switching operations to match the violent fluctuation state as the second number, and connect the second number of power supply units to the power supply circuit in sequence.

[0095] In the above steps S1-S3, firstly, the 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 range, the current fluctuation degree of the power supply circuit at the current moment is determined to be a slight fluctuation state; further, the number of power supply units that need to perform mode switching operation matching the slight fluctuation state is determined to be a first number, and the first number of power supply units are connected to the power supply circuit in sequence.

[0096] Optionally, the aforementioned current fluctuation coefficient can be calculated by taking the difference between the highest and lowest current values ​​over the past 10 seconds and the average historical fluctuation coefficient, thereby quantifying the current current fluctuation level. For example, if the current variation range over 10 seconds is 10A and the average current is 100A, then the current fluctuation coefficient is 10%. The aforementioned target performance state can be the optimal or normal operating state expected by the server or power system during design, including the system's performance when handling a specific workload, or its operating state under certain power consumption and efficiency conditions.

[0097] The aforementioned target adjustment factor can be calculated by taking the average of the current fluctuation coefficients monitored under normal workload conditions at historical time points (e.g., 8%, 9%, 10%, 11%...18%), which can be used as the target adjustment factor. This means that the average amplitude of current fluctuation is approximately 13% during normal system operation.

[0098] In some alternative implementations, if the ratio of the current fluctuation coefficient to the target adjustment coefficient at the current moment is between 0.8 and 1.2, it is determined that the current circuit is in a state of slight fluctuation. The range of the number of PSUs that need to be connected to the power supply circuit in the state of slight fluctuation can be determined in advance by machine learning algorithm. For example, if 3 new PSUs need to be connected in the state of slight fluctuation, the 3 PSUs are switched from Standby mode to 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. No specific restrictions are made here.

[0099] In steps S4-S5 above, when the ratio of the current fluctuation coefficient to the target adjustment coefficient is in the second reference range, the current fluctuation level of the power supply circuit at the current moment is determined to be a severe fluctuation state; the number of power supply units that need to perform mode switching operation 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 describes an optional implementation. Assume a server system with 8 PSUs, 4 in Active state and 4 in Standby state. The system's target adjustment factor is 5%, meaning that during normal operation, the acceptable current fluctuation range is ±5% of the average current value. If the monitored current fluctuation factor is 3%, and the ratio to the target adjustment factor is within the first reference range, the system determines it to be a slight fluctuation state. In this case, the system decides to switch only 2 PSUs into Active state to increase redundancy without significantly increasing power consumption.

[0101] If the current fluctuation coefficient suddenly increases to 10%, and the ratio is within the second reference range, the system determines it to be in a state of severe fluctuation. In order to quickly stabilize the current, the system may decide to simultaneously switch all four PSUs into Active state to improve the stability and redundancy of the current supply.

[0102] The above-described embodiments described in this application, namely the intelligent algorithm based on the ratio of current fluctuation coefficient to target coefficient, can dynamically predict in advance the number of new PSU modules that need to be connected in the power supply strategy. This enables the server power management system to achieve more efficient, stable, and safer power supply in complex and ever-changing working environments, and improves the efficiency of the power supply strategy.

[0103] In one optional implementation, according to the first alarm information, at least one power supply unit in sleep mode is sequentially connected to the power supply circuit until the comparison result between the current voltage value of each image processing unit and the matching standard voltage value is less than or equal to a first threshold, 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 matching standard voltage value is greater than the first threshold, a 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 matching standard voltage value is less than or equal to the first threshold. The power consumption limiting operation is used to adjust the operating frequency of the image processing unit to reduce the power consumption current of the image processing unit.

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

[0106] Through the above-described embodiments of this application, when all power supply units are in operating mode and the comparison result between the current voltage value of the first processing unit and its matching standard voltage value is greater than a first threshold, a 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 its matching standard voltage value is less than or equal to the first threshold. By limiting the power consumption of the image processing unit when the power supply units are operating at full load, system crashes caused by insufficient power supply are avoided, improving the server's fault tolerance and emergency response capabilities. This ensures that the server can maintain basic operation even under power constraints, 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 handling complex workloads by performing power limiting operations in a timely manner, while protecting critical hardware from damage caused by abnormal voltage, thereby improving the overall operating quality and lifespan of the server.
