Description

Technical Field

[0001] The present invention relates to the technical field of server power consumption management, and in particular to a power consumption control method, device, equipment and storage medium. Background Art

[0002] Dynamic power capping, on the one hand, means that when an overcurrent event is triggered, power consumption can be limited, rather than keeping the server in a power-limited state. When the overcurrent event ends, power consumption is restored to normal. On the other hand, it means that the power consumption limit value can be autonomously calculated based on the machine configuration without human intervention.

[0003] Compared to general-purpose servers, dynamic power capping for multi-node servers presents greater complexity. First, each node is independent, requiring individual node power consumption calculations. Second, each node has a unified power input and relies on a common PSU (Power Supply Unit). When an overcurrent event is triggered, each node must collectively adjust its power consumption to reduce system power consumption.

[0004] The dynamic power capping of multi-node servers is jointly implemented by the MPCPLD (MidPlane Complex Programmable Logic Device) and the BMC (Baseboard Management Controller). If any of them fails, it will affect the implementation of the dynamic power capping function of the multi-node server.

[0005] Therefore, in view of the shortcomings of the existing technical solutions, the present invention provides a power consumption control method. Summary of the Invention

They are merely for the convenience of describing the method of this application and should not be understood as indicating the order of the steps.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0027] In one embodiment, Figure 1 As shown, a power consumption control method is provided, which is applied to a multi-node server, wherein the multi-node server includes multiple nodes, a second processor, an external device, and a power supply unit, wherein each node includes a first processor, and the multiple nodes, the external device, and the power supply unit are respectively connected to the second processor, comprising the following steps:

[0028] S101: First processors and second processors in multiple nodes detect each other to determine states of the first processors and the second processors.

[0029] Here, the status of the processor includes a normal state and an abnormal state.

[0030] Here, the first processor is used for managing each node, and the second processor is used for managing multiple nodes, external devices, and a power unit, etc.

[0031] Here, the abnormal state refers to a state in which the processor cannot work normally due to flash refreshing during upgrading, code runaway, or other problems, and cannot support existing functions, in which case the processor is in an abnormal state.

[0032] For example, the first processor can be a BMC, and the second processor can be an MPCPLD. The dynamic power consumption ceiling function is completed by the MPCPLD and the BMC.

[0033] Here, the first processor in the abnormal state can be one first processor in the abnormal state, or multiple first processors in the abnormal state.

[0034] S102: In response to one or more first processors in multiple nodes being abnormal, the second processor determines the node power consumption corresponding to the abnormal first processor according to the received node power consumption, and determines the overall machine power consumption according to the node power consumption of each node and the power consumption of external devices.

[0035] Here, the power consumption of the external device can be the power consumption of a fan, a hard disk, etc.

[0036] Here, the first processor collects the node power consumption of each node and sends it to the second processor.

[0037] Specifically, when the first processor is in an abnormal state, it cannot collect node power consumption and send it to the second processor. The second processor determines the node power consumption of the abnormal node according to the received node power consumption, and thus calculates the overall machine power consumption.

[0038] In one embodiment, the second processor can preset a time range, and record whether the node power consumption of the node corresponding to the first processor in a normal state is received within the preset time range. If not, the power consumption control is ended. In this way, it can be prevented that the first processor of the existing node is normal, but the node power consumption cannot be sent in time, resulting in the influence of other links.

[0039] In one embodiment, the second processor sequentially detects whether the node corresponding to one or more abnormal first processors is in place. When it is detected that the node corresponding to the abnormal first processor is not in place, the power consumption control is ended.

[0040] S103: When the second processor receives the overcurrent alarm signal sent by the power unit, it determines and sends a power consumption limit value to the external device and the node corresponding to the first processor in a normal state according to the overall machine power consumption.

[0041] Here, the second processor may receive the overcurrent alarm signal sent by the power supply unit through a pin connected to the power supply unit.

[0042] Here, the power supply unit includes a plurality of PSUs for providing power.

[0043] The power consumption limit value includes the power consumption limit value of the external device and the power consumption limit value of the node, and the power consumption limit value of each node may be different.

[0044] Specifically, the power consumption of the node corresponding to the first processor in an abnormal state will not be reduced. The second processor can reduce the power consumption of the external device by controlling the power consumption limit value of the external device. At the same time, based on the power consumption of the entire machine, the power consumption limit value of each node corresponding to the first processor in a normal state is determined, and the power consumption limit value is sent to each node corresponding to the first processor in a normal state.

[0045] In one embodiment, after the second processor adjusts the power consumption limit value of the external device and the power consumption limit value of the node corresponding to the first processor in normal status, the second processor still receives the overcurrent alarm signal sent by the power supply unit, and then cuts off the power supply of the node corresponding to the abnormal first processor to protect the normal operation of other nodes.

[0046] S104: In response to the abnormality of the second processor, when the first processor in each node receives the abnormal signal sent by the power supply unit, the first processor in each node obtains the information of the power supply unit through the bus, and determines the power consumption limit value of each node based on the information of the power supply unit.

[0047] Here, the abnormal signal is used to indicate that the power supply unit is in an abnormal state, and cannot specifically indicate the type of abnormality.

[0048] In one embodiment, before the first processor in each node receives the abnormal signal sent by the power supply unit, it is assumed that the second processor is in an abnormal state. At this time, the first processor cannot calculate the power consumption and configuration of the entire machine. At this time, the dynamic power consumption capping function is turned off, the power consumption control is ended, and the first processor of each node automatically exits the dynamic power consumption capping state.

[0049] It should be noted that the present application implements a dynamic power consumption capping function when the first processor or the second processor is in an abnormal state.

[0050] In some specific embodiments, the first processor and the second processor in the multiple nodes determine the states of the first processor and the second processor by mutual detection, including:

[0051] The first processors in the multiple nodes are respectively connected to the second processors via pins;

[0052] The first processor and the second processor detect changes in pin levels, and determine states of the first processor and the second processor according to the changes in the pin levels.

[0053] Here, the pin may be a GPIO pin, a general-purpose input / output pin, used to implement input and output of digital signals.

[0054] Specifically, the first processor and the second processor of each node are connected through two pins. One pin is used by the first processor to detect whether the second processor is in an abnormal state, and the other pin is used by the second processor to detect whether the first processor is in an abnormal state. When one of the processors is detected to be in an abnormal state, the pin level will change, and the other processor will detect the change in the pin and detect the processor in the abnormal state.

[0055] In this way, the first processor and the second processor are connected through the pins to detect the status of the processors, and the signal is stable and the response speed is fast.

[0056] In some specific embodiments, the first processor and the second processor in the multiple nodes determine the states of the first processor and the second processor by mutual detection, including:

[0057] The first processors in the plurality of nodes respectively send an excitation signal to the second processors;

[0058] If the first processor of the plurality of nodes detects that no response is received from the second processor within a first time interval after the stimulus signal is sent, determining that the state of the second processor is an abnormal state;

[0059] The second processor monitors that the first excitation signal sent by the first processor of each node is not received within a preset second time interval, and determines that the state of the first processor that does not send the signal is an abnormal state.

[0060] Here, the sizes of the first time interval and the second time interval can be adjusted according to user needs.

[0061] The multiple first processors may send excitation signals to the second processor simultaneously, or may send excitation signals to the second processor at different times.

[0062] Specifically, a request and response mechanism is used. The first processor sends an activation signal to the second processor at regular intervals. Upon receiving the signal from the first processor, the second processor responds. If neither the first processor nor the second processor sends a response signal within a certain period of time, it indicates that one of the processors is in an abnormal state.

[0063] In one embodiment, the second processor may also send an excitation signal to the multiple first processors and receive responses from the first processors to detect whether the multiple first processors are in an abnormal state.

[0064] In this way, by sending an excitation signal to detect the status of the processor, mutual detection can be achieved without occupying hardware resources.

[0065] In some specific implementations, the second processor determines the node power consumption corresponding to the abnormal first processor based on the received node power consumption, including:

[0066] The second processor determines a maximum value of the multiple node power consumptions based on the received node power consumptions corresponding to the multiple normal first processors;

[0067] The second processor uses the maximum value as the power consumption of nodes corresponding to the one or more abnormal first processors.

[0068] In one embodiment, the user may set the configuration of each node in advance. When the first processor is abnormal, the power consumption corresponding to the preset configuration is used as the power consumption of the abnormal node received by the second processor.

[0069] In this way, the problem that the first processor is unable to report the node power consumption due to being in an abnormal state can be solved.

[0070] In some specific embodiments, when the second processor receives the overcurrent alarm signal sent by the power supply unit, determining and sending the power consumption limit value to the external device and the node corresponding to the first processor in a normal state according to the power consumption of the entire machine includes:

[0071] The second processor determines, based on the overall power consumption of the device, and sends the power consumption limit value of the external device to the external device;

[0072] Determine the total power consumption of nodes corresponding to the plurality of first processors in normal states according to the power consumption of the entire machine and the power consumption limit value of the external device;

[0073] According to the total power consumption value and the power consumption requirement of the node corresponding to each normal first processor, the power consumption limit value corresponding to the node corresponding to each normal first processor is determined and sent to the node corresponding to each normal first processor.

[0074] Here, the power consumption requirement of the node can be determined according to the current operating state of the node, the configuration of the node, etc.

[0075] The total power consumption value may be allocated by weighting or other methods to determine the power consumption limit value of each node.

[0076] Thus, different power consumption limit values are configured according to different power consumption requirements of each normal node, and the influence of the power consumption limit on the node corresponding to the state normal first processor is reduced.

[0077] In some embodiments, before the response to the second processor exception, the method further comprises:

[0078] The second processor determines a whole machine configuration according to the whole machine power consumption, wherein the whole machine configuration comprises a configuration of a power supply unit;

[0079] The second processor sends the whole machine configuration to the first processor in each node.

[0080] Here, the power supply unit comprises a plurality of PSUs, and a part or all of the PSUs are determined to be enabled according to the whole machine power consumption and the whole machine configuration.

[0081] The whole machine power consumption is required to be less than or equal to the maximum value of the power consumption supported by all the PSUs in the power supply unit.

[0082] Further, the second processor sends the whole machine configuration and the whole machine power consumption to the first processor in each node after determining the whole machine configuration, and the first processor checks whether the whole machine power consumption meets the requirement of power consumption capping after receiving the whole machine configuration and the whole machine power consumption, and if not, the dynamic power consumption capping is closed. Exemplarily, there can be a case that the maximum power consumption that can be supported by the power supply unit is less than the whole machine power consumption, and there can also be a case that the whole machine power consumption is calculated as 0 due to transmission error.

[0083] In some embodiments, the first processor in each node obtains information of the power supply unit through a bus, and determines a power consumption limit value of each node according to the information of the power supply unit, comprising:

[0084] The first processor in each node obtains a state register of the power supply unit through a power management bus, and determines whether there is a data exception in the state register;

[0085] When there is a data exception in the state register, the first processor in each node obtains an in-place state of the power supply unit through the power management bus;

[0086] The configuration of the power supply unit in the whole machine configuration and the in-place state of the power supply unit are compared, and when the configuration of the power supply unit in the whole machine configuration and the in-place state of the power supply unit are the same, it is determined that the in-place state of the power supply unit is normal;

[0087] When the in-place state is normal and the data exception of the state register exists, it is determined that the power supply unit is in an overcurrent state;

[0088] The first processor in each node calculates a power consumption limit value corresponding to each node according to the power consumption requirement of each node;

[0089] The first processor in each node controls the power consumption of each node according to the power consumption limit value.

[0090] Here, when the second processor is in an abnormal state, the first processor and the power supply unit may interact via a PMBUS (Power Management Bus).

[0091] Among them, whether the node is in place can be detected through sensors, conductive contacts, dedicated signal lines, bus interfaces, etc.

[0092] Among them, when the second processor is abnormal, the first processor receives the abnormal signal sent by the power supply unit and cannot determine the specific abnormal type of the power supply unit. By detecting the in-place status and status register of the power supply unit, it is determined that the power supply unit is overcurrent abnormal, thereby implementing power consumption control.

[0093] Specifically, when the second processor is abnormal, the first processor cannot obtain the power consumption control instruction sent by the second processor. The first processor receives the whole machine configuration sent by the second processor. The first processor interacts with the power supply unit through PMBUS to detect the in-place status and status register of the power supply unit. When the in-place status of the power supply unit does not meet the whole machine configuration and the status register data is abnormal, multiple nodes need to perform power consumption control. Each first processor determines the power consumption limit value of the corresponding node based on the power consumption requirements of the node, and sends it to the corresponding ME (Management Engine) for power consumption control.

[0094] In one embodiment, when the first processor is normal, after power is restored or the second processor is restored, the power of the node corresponding to the first processor is reset to normal.

[0095] In this way, when the second processor is in an abnormal state, the first processor can control the power consumption of each node.

[0096] In some specific implementations, when the first processor in each node receives the abnormal signal sent by the power supply unit, the process includes:

[0097] The first processor records the duration of receiving the abnormal signal;

[0098] The duration is compared with a standard duration, and when the duration is greater than the standard duration, power consumption control is performed on each node.

[0099] Here, the standard duration can be set according to user needs.

[0100] In this way, misjudgment of abnormal situations can be avoided through continuous abnormal signals.

[0101] In one embodiment, Figure 2 This is a schematic diagram of the dynamic power consumption capping state flow in the embodiment of the present application, such as Figure 2 As shown, the dynamic power consumption capping state flow includes: when the dynamic power consumption capping function is not enabled, it is in the dynamic power consumption capping closed state; when this function is enabled, the first processor will calculate the current node power consumption according to the current configuration of the node, and after the calculation is completed, the result will be sent to the second processor; after the second processor receives the node power consumption sent by the first processor of all nodes, it accumulates the values, calculates the power consumption of the entire machine, and calculates the entire machine configuration information based on the entire machine power consumption, and sends the configuration information to the first processor. When it is not enabled or the accumulation timeout occurs, it is in the dynamic power consumption capping closed state; the second processor monitors the health status of the power supply unit. After receiving the entire machine configuration information of the second processor, the first processor checks whether the configuration meets the power consumption capping requirements. If not, it is in the dynamic power consumption capping closed state; if it meets the requirements, the first processor starts to monitor the throttling signal sent by the second processor. If the signal is received, the node power consumption is capped.

[0102] In one embodiment, Figure 3 This is a schematic diagram of the system architecture in the embodiment of the present application. Figure 3 As shown, the system architecture in this application includes: multiple nodes, MPCPLD or CMC, power supply unit and external devices.

[0103] Specifically, each of the multiple nodes consists of a mainboard and external devices, including a network card, a RAID (Redundant Arrays of Independent Disks) card, a BMC, a mainboard CPLD (Complex Programmable Logic Device), a CPU (Central Processing Unit), memory, and an ME. Each node can be managed through the BMC on its own mainboard. Each node's BMC can request information about common components in the entire system by sending a request to the MPCPLD or CMC.

[0104] Specifically, the MPCPLD or CMC manages all nodes, processes multi-node information, and manages external devices and power supply units. The MPCPLD or CMC delivers power from the power supply unit to each node and external device, and can obtain the health status of the power supply unit. The MPCPLD or CMC can also control fan speed and obtain hard disk information.

[0105] Specifically, the power supply unit is used to supply power to the entire machine.

[0106] Specifically, the external devices may include fans, hard disks, etc. The external devices are centrally managed by the MPCPLD or CMC.

[0107] For example, when a PSU in a power supply unit fails, the unit sends an overcurrent alarm signal to the MPCPLD. Upon receiving the overcurrent alarm signal, the MPCPLD sends a throttling signal to the BMC of each node, triggering the BMC to cap power consumption. Once the BMC has capped power consumption, it notifies the MPCPLD that throttling is complete. The MPCPLD then waits for the failed PSU to be replaced with a healthy one before clearing the alarm.

[0108] It should be understood that although Figure 1-3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 1-3 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
