However, when one or more of the power supplies is damaged or one of the circuits fails, the total output capacity of the CRPS power supply is rapidly reduced, and at this time, the power consumption of the system is far greater than the power supply capacity of the CRPS power supply, so that the CRPS power supply is overloaded, and the system is turned off accidentally.

Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples, and it is apparent that the examples described below are part of the examples of the present application, which are provided for illustration only and are not intended to limit the scope of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The method for reducing the power consumption of the whole machine is a method for monitoring various triggering power consumption reduction events based on a baseboard management controller (Baseboard Management Controller, BMC) which is realized on the basis of the existing flow architecture shown in the figure 1, timely adjusting the working state of a system and carrying out efficient and reliable dynamic regulation and control on a power consumption module of the system according to the power supply capacity of the system, and can not only ensure the normal operation of the system when facing power failure or other scenes needing to reduce the power consumption of the system, but also quickly reduce the power consumption of the system, avoid the system downtime caused by PSU overload, effectively maintain the stability of the system and the continuity of service, and quickly restore the server system to the normal state when corresponding failure recovery or other scenes needing to restore the normal power consumption. The following embodiments will describe the overall power consumption reduction method of the present invention in detail.
In one embodiment, as shown in fig. 2, a method for reducing power consumption of a complete machine is provided, including the following steps:
s11, responding to the starting-up operation of the server system, setting the operation state of the system into a normal operation mode through a baseboard management controller, setting each part of the system into corresponding normal operation power consumption, and monitoring and triggering a power consumption reduction event in real time; the server system can be divided into a CPU module, a fan module, a memory module, a hard disk module, a PCIe card and the like according to functional modules, and a baseboard management controller BMC which is connected with the functional modules and is used for carrying out real-time monitoring management on the functional modules; the system running state in this embodiment may be understood as a working mode determined based on whether the current system is in a normal running power consumption state, including a normal working mode and a low power consumption working mode; the normal working mode can be understood as that the BMC does not monitor the trigger power consumption reduction event, and each functional module of the system operates according to the established normal power consumption. In principle, the maintenance and update of the system running state can be realized by adding other functional modules, but considering that the BMC can monitor the system state in real time in the running process of the server system, and the power consumption adjustment needs to depend on the relevant monitoring result of the BMC, in order to realize simple and efficient maintenance and update of the system running state under the condition of reducing the system variation as much as possible and not introducing the system running risk, the embodiment is preferable, the BMC directly maintains the system running state, namely the BMC defaults the system running state to be in a normal working mode when the server is normally started, updates and maintains the system running state according to the condition of triggering the power consumption reduction event by real-time monitoring, and provides a reliable basis for the subsequent efficient and accurate dynamic adjustment of the system power consumption;
The above-mentioned triggering power consumption reduction event may in principle only include the situation that the power supply module (PC Power supply unit, PSU) is accidentally powered down (out of place), or the power supply capability of the power supply module is failed (in place but the power supply capability is insufficient), that is, only the BMC is required to monitor whether the PSU is normal (in place) and whether the PSU is normal (whether the power supply capability is normal) in working state, but in consideration of the actual application process of the server system, certain operation and maintenance adjustment scenes may be involved, the system power consumption needs to be rapidly reduced to perform problem location or performance verification under the situation that the power supply is in place and the power supply capability is normal, in order to effectively meet the power consumption dynamic adjustment requirement of the network terminal, convenience is provided for more operation and maintenance adjustment scenes, and in this embodiment, the triggering power consumption reduction event is preferably expanded; specifically, the triggering power consumption reduction event includes a power failure, a power supply failure or a network terminal sending a power consumption reduction request, where the network terminal sending the power consumption reduction request may be understood as a request for quickly reducing power consumption, which is sent by a relevant operation and maintenance person or a machine room control end through a network and received and processed by the BMC;
S12, when the baseboard management controller monitors the trigger power consumption reduction event, the running state of the system is adjusted to be in a low-power consumption working mode, and after a preset time period, the power consumption of the system is dynamically adjusted according to the power supply capacity of the power supply until the system receives a shutdown command to shutdown; the low-power-consumption working mode can be understood as a system running state that a part of functional modules of the system corresponding to the normal working mode run in a power consumption state lower than the normal power consumption; when the server system is in normal operation in the system operation state of the normal working mode, if the baseboard management controller monitors any trigger event of power failure, power supply failure or power consumption reduction request sent by the network terminal, the system operation state is updated to the low-power consumption working mode at the first time so as to ensure the efficient execution of the subsequent system power consumption adjustment flow; meanwhile, when the BMC updates the running state of the system into a low-power-consumption working mode, the running state of the system can be synchronously entered into a system power consumption adjustment flow in principle for quickly reducing power consumption, but in consideration of the fact that certain monitoring results may be misaligned in the actual running process, in order to ensure that the system power consumption is effectively adjusted in time when the monitoring results are actually required to be reduced, unnecessary adjustment or twice reverse adjustment in a short time can be effectively avoided, which is caused by the fact that the monitoring results are misaligned, so that the risk of running instability of the server system is caused, the embodiment preferably carries out dynamic adjustment on the system power consumption according to the power supply capacity after the system enters the low-power-consumption working mode for a period of time, controls the whole power consumption within a safe range, and avoids the system downtime caused by overload protection and stopping output of PSU; it should be noted that the preset duration may be selected according to the actual application requirement, which is not limited herein.
In addition, after the server starts to run, no matter whether the system has load or not, the functional modules such as the CPU module, the fan module, the memory module, the hard disk module, the PCIe card and the like have corresponding power consumption, so when the functional modules are selected as power consumption adjustment objects in the situation of fast lower system power consumption is critical to the overall power consumption reduction operation. In order to ensure that the selection process of each power consumption adjustment object is simple and reliable, and the application requirement of effectively reducing the power consumption of the whole system in a short time can be met, the embodiment is preferable in that the power consumption of each functional module in the server is subjected to statistical analysis in advance, the functional module with larger maximum power consumption and controllable power consumption adjustment influence is screened out to be used as the power consumption module to be reduced, and when the power consumption needs to be reduced, the corresponding adjustment operation can be directly carried out on each power consumption module to be reduced; specifically, the step of dynamically adjusting the system power consumption according to the power supply capability of the power supply includes:
According to the power supply capacity of the power supply, carrying out power consumption reduction adjustment on the pre-screened power consumption module to be reduced; the pre-screened power consumption module to be reduced comprises a CPU module and a fan module; the determination process of the power consumption module to be reduced is described by the following general two-way server example:
acquiring power consumption information of each functional module of the server under the two conditions of no load and load of the system through a BMC web page in advance, summarizing the acquired power consumption information under the two conditions to obtain a module statistical result shown in a rear table 1, and analyzing based on the table 1 to obtain the power consumption ratio of each functional module shown in fig. 3;
Table 1 individual component power consumption information for each functional module of a server system
| Component classification | Individual component power consumption | Quantity of | Power consumption | Power consumption duty cycle |
| Processor and method for controlling the same | 250 | 2 | 500 | 0.242718447 |
| Memory | 15 | 32 | 480 | 0.233009709 |
| Hard disk | 15 | 12 | 180 | 0.087378641 |
| PCIe card | 75 | 6 | 450 | 0.218446602 |
| Fan with fan body | 75 | 6 | 450 | 0.218446602 |
| Totals to | 2060 |
Based on the analysis result shown in fig. 3, the power consumption of the processor (CPU), the fan, the memory and the PCIe card are more than twenty percent on average, but during the operation of the server, the modules such as the memory, the hard disk, the PCIe card and the like cannot be directly turned off, otherwise, the problems such as hardware resource loss and downtime of the operating system are caused, the power consumption of the remaining CPU module and the fan module can be adjusted, and as can be seen from the duty ratio, the total power consumption of the CPU module and the fan module is close to 50%, if the power consumption close to 50% can be reduced, the power PSU cannot be overloaded, and the normal operation of the system can be maintained; therefore, the purpose of rapid power consumption reduction can be achieved by adjusting the power consumption of the CPU module and the fan module, namely, the CPU module and the fan module can be directly used as the power consumption module to be reduced, and when the BMC monitors power failure, power supply failure or a network terminal sends a power consumption reduction request and other trigger power consumption reduction events, the CPU module and the fan module can be directly subjected to corresponding power consumption adjustment;
in the embodiment, through carrying out statistical analysis on the power consumption information of each functional module in the actual running of the server and combining with the actual working principle of the server, the to-be-reduced power consumption module which can be directly used for adjustment after the BMC monitors the trigger power consumption reduction event is screened out, so that the rationality and reliability of selection of the power consumption adjustment module are ensured, and when the power consumption reduction processing is determined to be required, the selected to-be-reduced power consumption module can be directly and timely adjusted in a preset mode, the operation duration of reducing the system power consumption can be effectively shortened, and further, the guarantee is provided for rapid reduction of the system power consumption;
In addition, in order to reduce system variation as much as possible, without introducing additional system operation risk and reducing system development and operation cost, the embodiment preferably adopts a substrate management controller to transmit corresponding power consumption reduction instructions to a CPU module and a fan module to realize efficient and reliable power consumption reduction adjustment of the power consumption module to be reduced; specifically, as shown in fig. 4, the step of performing power consumption reduction adjustment on the pre-screened power consumption module to be reduced according to the power supply capability of the power supply includes:
transmitting a frequency-reducing command to a CPU module interface through the baseboard management controller, and reducing the duty ratio of a rotating speed signal corresponding to the fan module;
the down-conversion command can be transmitted to the CPU module interface in principle by directly writing cTDP (Configable THERMAL DESIGN Power) register values, but in order to ensure the execution effect of reducing the Power consumption of the CPU module, the embodiment preferably provides another down-conversion mode at the same time so as to meet the selection requirements of different application scenarios; specifically, the step of transmitting the down-conversion command to the CPU module interface through the baseboard management controller includes:
Reducing cTDP register values corresponding to the CPU module to a first preset value; the first preset value may be understood as a minimum frequency value which is determined according to an actual application scenario and can be written into cTDP register values by the BMC and ensures the operation of the CPU, and is not particularly limited herein;
Or, pulling down the CPU down-conversion signal to a second preset value through the general input/output port; the second preset value may also be understood as a minimum CPU thread signal value that is determined according to an actual application scenario and that can be input by the BMC through the GPIO and that ensures the operation of the CPU, which is not specifically limited herein.
After the operation frequency of the CPU is reduced through the steps, the effective reduction of the corresponding operation power consumption can be synchronously realized, namely, if the corresponding first preset value or second preset value is to reduce the operation frequency of the CPU module to the minimum value, the corresponding operation power consumption is also reduced to the minimum value; meanwhile, as the running frequency of the CPU module is reduced, the operation of the CPU module on components such as a memory module, a hard disk module, a PCIe card and the like is also reduced, and the power consumption of the corresponding components is naturally and synchronously reduced; in principle, the method can realize the efficient and reliable reduction of the running power consumption of the CPU module, but considers that the power supply capacity (output power consumption) of the system power supply PSU can exceed the adjusted system power consumption requirement due to the fact that the power consumption adjustment threshold value is used, so that the utilization rate condition of the output power consumption of the power supply PSU is reduced, and in order to ensure that the CPU performance is maximized within the power supply capacity range of the power supply PSU and further ensure the processing efficiency of the server system, in the embodiment, after the power consumption of the CPU module is reduced, whether the frequency of the CPU module needs to be finely adjusted is further judged according to the adjusted power supply output power consumption and the current system power consumption; specifically, the step of transmitting the down-conversion command to the CPU module interface through the baseboard management controller further includes:
acquiring power output power consumption and current system power consumption in real time, and judging whether the power output power consumption is larger than the current system power consumption or not;
If yes, the cTDP register value corresponding to the CPU module is increased to the maximum allowable frequency value of the current CPU, otherwise, the cTDP register value corresponding to the CPU module is kept unchanged; the maximum allowable frequency value of the current CPU can be understood as the maximum operating frequency of the CPU which can be supported in the current power output power consumption range, and can be determined according to the actual system operating condition, and the maximum allowable frequency value is not particularly limited herein; it should be noted that, after the adjustment processing is performed on the cTDP register values by acquiring the power output power consumption and the current system power consumption in real time, the CPU operating frequency needs to be dynamically adjusted by repeatedly acquiring the power output power consumption and the current system power consumption to perform judgment and analysis, so as to ensure the rationality of the system power consumption adjustment at different moments as much as possible.
Specifically, the step of reducing, by the baseboard management controller, a duty ratio of a rotational speed signal corresponding to the fan module includes:
reducing pulse width modulation registers of all fan rotating speed controllers corresponding to the fan modules to a third preset value; the third threshold value may be understood as an expected fan speed PWM signal duty cycle value that may be determined by the BMC according to an actual application scenario and expected to be reached by writing PWM AND FAN Tachometer Controller related registers, and the fan speed PWM signal duty cycle may be adjusted to be 10 or lower, which is not particularly limited herein; for example, if there are 6 fan units in the fan module, the BMC adjusts the duty ratio of the PWM signal of the output fan speed by controlling the fan speed, so as to rapidly reduce the power consumption of the fan module, as follows:
Rotational speed control signal of fan 1: writing a register 0x1E61:0000+004H to realize FAN1PWM duty cycle data control, thereby realizing the rotation speed control of the FAN 1;
rotational speed control signal of fan 2: writing a register 0x1E61:0000+010H to realize the data control of the FAN2PWM duty ratio, thereby realizing the rotation speed control of the FAN 2;
rotational speed control signal of fan 3: writing a register 0x1E61:0000+01CH to realize the data control of the FAN3PWM duty ratio, thereby realizing the rotation speed control of the FAN 3;
Rotational speed control signal of fan 4: writing a register 0x1E61:0000+028H to realize the control of FAN4PWM duty cycle data, thereby realizing the control of the rotating speed of the FAN 4;
rotational speed control signal of fan 5: writing a register 0x1E61:0000+034H to realize the data control of the FAN5PWM duty cycle, thereby realizing the rotation speed control of the FAN 5;
rotational speed control signal of fan 5: the write register 0x1E61:0000+040H realizes the data control of the FAN6PWM duty cycle, thereby realizing the rotation speed control of the FAN 6.
In practical application, the method can realize the rapid reduction of the running power consumption of the fan module, in principle, the running power consumption of the modules such as a CPU, a memory and a hard disk can be synchronously reduced due to the reduction of the running frequency of the CPU, the corresponding temperature rise is slower, the synchronous reduction of the fan rotating speed has little influence on the system, but the stability of a server and the continuous requirement of service are considered, in order to avoid the risk of system downtime caused by the over-temperature of the server system due to the too fast temperature rise of the CPU module and the memory module under the condition of reducing the fan rotating speed as far as possible, the implementation preferably shortens the temperature polling interval of the system after the reduction of the power consumption of the fan module, and strengthens the temperature monitoring of the CPU and the memory so as to discover the temperature abnormality in time for necessary regulation; specifically, the step of reducing, by the baseboard management controller, the duty ratio of the rotational speed signal corresponding to the fan module further includes:
Shortening the system temperature polling interval, and acquiring the CPU polling temperature and the memory polling temperature of the system through the baseboard management controller; the shortening degree of the system temperature polling interval can be set according to practical application requirements, and is not particularly limited herein;
Judging whether a preset working condition is met or not according to the CPU polling temperature and the memory polling temperature; the preset working condition is that the CPU polling temperature is within a first preset temperature threshold value, and the memory polling temperature is within a second preset temperature threshold value; the first preset temperature threshold and the second preset temperature threshold can be understood as corresponding protection temperature threshold points allowed by system operation, can be selected according to actual application requirements, can be set identically or differently, and are not particularly limited herein;
If not, gradually increasing the duty ratio of the rotating speed signal corresponding to the fan module according to a preset speed increasing step length until the CPU polling temperature and the memory polling temperature meet the preset working conditions, and reducing the pulse width modulation register of each fan rotating speed controller corresponding to the fan module to a third preset value after the CPU polling temperature and the memory polling temperature meet the preset working conditions; the preset speed increasing step length can be understood as a ratio of a rotating speed signal duty ratio of the fan module every time, and can be determined according to practical application requirements, for example, if the preset speed increasing step length is 10%, after detecting that the temperature of the CPU module or the memory module reaches a preset protection temperature threshold point, the fan rotating speed can be increased by 10% to adjust, so as to ensure reliable working environments of the CPU and the memory, if the temperature of the CPU module or the memory module is not reduced to a corresponding safety threshold after the rotating speed of the fan is increased for a period of time, the fan rotating speed is continuously increased by 10%, and a temperature monitoring result after a period of time is waited for processing until the polling temperature of the CPU module is reduced to be within a first preset temperature threshold range, and the polling temperature of the memory module is also reduced to be within a second preset temperature threshold range; after determining that the temperatures of the CPU module and the memory module are both reduced to be within the corresponding safe ranges, in order to avoid overload of the power PSU, the rotational speed of each fan in the fan module is reduced to the third preset value again, that is, the power consumption of the fan module is reduced again;
