However, in the above method, the energy consumption of the computing device is high. SUMMARY

[0004] Embodiments of the present application provide a computing device, which is used to solve the technical problem of high energy consumption of the computing device.

[0005] In a first aspect, an embodiment of the present application provides a computing device, comprising: a power module, configured to output a direct current bus voltage;

[0006] at least one first type component, wherein the at least one first type component is connected with the power module respectively, and a power supply voltage of the first type component is the direct current bus voltage; and if the power supply voltage of the first type component is abnormal, a first level alarm signal is outputted;

[0007] a voltage conversion circuit, wherein an input end of the voltage conversion circuit is connected with the power module, and an output end of the voltage conversion circuit is configured to output a set voltage;

[0008] at least one second type component, wherein the at least one second type component is connected with the output end of the voltage conversion circuit, and a power supply voltage of the second type component is the set voltage; and if the power supply voltage of the second type component is abnormal, a second level alarm signal is outputted;

[0010] In the above scheme, the manager can dynamically adjust the direct current bus voltage outputted by the power module and the set voltage outputted by the voltage conversion circuit, so as to possibly reduce the voltage applied to the first type component and the second type component, and thereby reduce the energy consumption of the computing device.

[0012] In the scheme, the manager can adjust the DC bus voltage according to the minimum working voltage of each first-type component, thereby achieving the purpose of adjusting the DC bus voltage.

[0013] In a possible implementation, the minimum value of the DC bus voltage output by the power module is a first voltage, and the maximum value is a second voltage.

[0014] If the minimum working voltage of a first-type component in the at least one first-type component is greater than the first voltage, the manager is configured to adjust the DC bus voltage output by the power module to the second voltage.

[0015] If the minimum working voltage of each first-type component in the at least one first-type component is less than or equal to the first voltage, the manager is configured to adjust the DC bus voltage output by the power module according to the alarm type of the first-level alarm signal.

[0017] In the scheme, the manager can adjust the DC bus voltage according to the minimum working voltage of each first-type component, thereby achieving the purpose of adjusting the DC bus voltage.

[0018] In a possible implementation, the alarm type is used to indicate the severity of an abnormality, and the severity of the abnormality corresponds to a voltage adjustment step length in a one-to-one manner.

[0019] The voltage adjustment step length corresponding to a first alarm type is greater than the voltage adjustment step length corresponding to a second alarm type, where the severity of the abnormality indicated by the first alarm type is higher than the severity of the abnormality indicated by the second alarm type.

[0020] In the scheme, the higher the severity of the abnormality indicated by the alarm type, the greater the voltage adjustment step length corresponding to the alarm type. This achieves the purpose of performing different voltage adjustments for different first-level alarm signals.

[0021] In a possible implementation, the manager is configured to determine a first voltage adjustment step length according to the alarm type of the first-level alarm signal, and to adjust the DC bus voltage output by the power module according to the first voltage adjustment step length and the current DC bus voltage.

[0023] In a possible implementation, the first voltage adjustment step length and the current DC bus voltage are summed to obtain a first sum value;

[0024] If the first sum value is less than the second voltage, the manager is configured to adjust the DC bus voltage output by the power module to the first sum value.

[0025] If the first sum value is greater than or equal to the second voltage, the manager is configured to adjust the DC bus voltage output by the power module to the second voltage.

[0026] In the scheme, the manager can determine the corresponding voltage adjustment step length according to the alarm type, and achieve the purpose of determining different voltage adjustment step lengths for different first-level alarm signals.

[0027] In a possible implementation, the alarm type of the second-level alarm signal includes at least two of the following: an emergency type, a serious type, and a slight type.

[0028] The alarm type is used to indicate the severity of the abnormality, and the severity of the abnormality corresponds to the voltage adjustment step length one-to-one.

[0029] The voltage adjustment step length corresponding to the first alarm type is greater than the voltage adjustment step length corresponding to the second alarm type, and the severity of the abnormality indicated by the first alarm type is higher than the severity of the abnormality indicated by the second alarm type.

[0030] In the scheme, the higher the severity of the abnormality indicated by the alarm type, the greater the voltage adjustment step length corresponding to the alarm type. The purpose of different voltage adjustments for different first-level alarm signals is achieved.

[0031] In a possible implementation, the manager is configured to determine a second voltage adjustment step length according to the alarm type of the second-level alarm signal, and to adjust a set voltage output by the voltage conversion circuit according to the second voltage adjustment step length and the current set voltage.

[0032] In the scheme, the manager can determine the corresponding voltage adjustment step length according to the alarm type, and achieve the purpose of determining different voltage adjustment step lengths for different first-level alarm signals.

[0033] In a possible implementation, the second voltage adjustment step length and the current set voltage are summed to obtain a second sum value, and the maximum value of the set voltage output by the voltage conversion circuit is a third voltage.

[0034] If the second sum value is less than the third voltage, the manager is configured to adjust the set voltage output by the voltage conversion circuit to the second sum value;

[0035] If the second sum value is greater than or equal to the third voltage, the manager is configured to adjust the set voltage output by the voltage conversion circuit to the third voltage.

[0036] In the above solution, the manager can determine the adjusted set voltage according to the second sum value and the third voltage, thereby achieving the purpose of determining the adjusted set voltage.

[0037] In a possible implementation, the computing device further includes a digital-to-analog converter (DAC);

[0038] The manager is configured to adjust the set voltage output by the voltage conversion circuit through the DAC.

[0039] In the above solution, the manager can adjust the set voltage output by the voltage conversion circuit through the DAC, thereby achieving the purpose of dynamically adjusting the set voltage output by the voltage conversion circuit.

[0040] In a possible implementation, the response priority of the first-level alarm signal is higher than that of the second-level alarm signal.

[0041] In the above solution, if the DC bus voltage output by the power module and the set voltage output by the voltage conversion circuit both need to be adjusted, the DC bus voltage output by the power module can be adjusted first, and then the set voltage output by the voltage conversion circuit is adjusted, thereby avoiding repeated adjustment of the set voltage output by the voltage conversion circuit multiple times, and achieving a higher voltage adjustment speed.

[0050] The exemplary embodiments will be described in detail herein below with reference to the drawings. When the following description refers to the drawings, identical numbers on different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the embodiments of the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of the present application as detailed in the appended claims.

[0051] For the sake of understanding, the technical terms involved in the embodiments of the present application are first explained.

[0052] Bus voltage: refers to the DC voltage output by a power supply unit (PSU) through an AC-DC converter. The bus voltage on a server is generally about 12V.

[0053] For the sake of understanding, the following describes an application scenario of the embodiments of the present application. Figure 1 The application scenario of the embodiments of the present application is described as follows.

[0054] Figure 1 A flowchart of a voltage regulation method provided by an embodiment of the present application is shown in FIG. 1. Figure 1 The computing device can include a first type of component, a second type of component, a PSU, and a DC-DC converter. The PSU can be connected to the first type of component, and the PSU can be connected to the second type of component through the DC-DC converter.

[0055] The computing device can be a server, a laptop computer, a desktop computer, a tablet computer, or an artificial intelligence device, etc. The server can be a Graphics Processing Unit (GPU) server or an Artificial Intelligence (AI) server, etc.

[0056] The first type of component can be a board card or a device on the board card. When the first type of component is a device, if the device itself does not have an alarm function, the alarm can be realized through an alarm circuit connected to the device or a monitoring device. Similarly, the second type of component can include a board card or a device on the board card. When the second type of component is a device, if the device itself does not have an alarm function, the alarm can be realized through an alarm circuit connected to the device or a monitoring device.

[0057] The first type of component can include a hard disk, a Redundant Array of Independent Disks (RAID) card, a 12V powered network card, etc.

[0058] The second type of component can include an M.2 card, a 3.3V powered network card, a temperature sensor, etc.

[0059] It should be understood that the output voltage of the PSU can be a bus voltage (for example, the bus voltage can be 12V), and the output voltage of the DC-DC converter can be less than the bus voltage. That is, the PSU can directly or indirectly provide the first type of component with the bus voltage, and can provide the second type of component with a voltage less than the bus voltage through the DC-DC converter.

[0060] In the above scenario, the energy consumption of the computing device can include the power supply energy consumption of the first type of component and the second type of component.

[0061] Embodiments of the present application provide a computing device for reducing the energy consumption of the computing device.

[0062] The technical solutions of the embodiments of the present application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0063] Figure 2 A structural schematic diagram of a computing device provided by the embodiments of the present application is shown in FIG. 1. Referring to FIG. 1, the computing device can include a power supply module, at least one first type of component, a voltage conversion circuit, at least one second type of component, and a manager. Figure 2 The number of the power supply module, the first type of component, the voltage conversion circuit, and the second type of component can be one or more. Figure 1The description is only exemplary and does not limit the technical solutions provided by the embodiments of the present application.

[0064] The power module can be used to output a DC bus voltage. For example, the power module can be a PSU, the input of the power module can be 220V AC, and the output DC bus voltage of the power module can be 12V.

[0065] The at least one first type component is respectively connected with the power module, and the power supply voltage of the first type component is the DC bus voltage. That is, the first type component can be a component in the computing device whose power supply voltage is the DC bus voltage. For example, the first type component can be a hard disk, or a RAID, etc.

[0066] The voltage conversion circuit has an input end connected with the power module and an output end used to output a set voltage. The set voltage is less than the DC bus voltage. That is, the voltage conversion circuit can be used to convert the output voltage of the power module into a smaller set voltage. For example, the voltage conversion circuit can be a DC-DC adjustable converter.

[0067] The set voltage can be set according to actual needs, and the embodiments are not limited in this regard. For example, the set voltage can be 1.8V, 3.3V or 5V, etc.

[0068] The at least one second type component is connected with the output end of the voltage conversion circuit, and the power supply voltage of the second type component is the set voltage. That is, for example, the second type component can be a temperature sensor, etc.

[0069] The manager can be a management unit independent of the operating system of the computing device and a non-business module. For example, the manager can be a baseboard management controller (BMC), a monitoring management device or a system management module (SMM), etc. The embodiments of the present application do not limit the specific form of the manager, and the above is only exemplary description. In the following embodiments, the manager is taken as an example of BMC for description.

[0070] It should be noted that in different computing devices, the BMC is called differently. For example, in some computing devices, it is called BMC, in some other computing devices, it is called iLO (integrated lights-out), and in some other computing devices, it is also called iDRAC (integrated dell remote access controller). Whether it is BMC, iLO or iDRAC, it can be understood as the BMC in the embodiments of the present application.

[0071] The manager can be connected with each first-type component and each second-type component respectively. The manager can also be connected with the power module and the voltage conversion circuit respectively.

[0072] In this embodiment, if the supply voltage of the first-type component is abnormal, the first-type component can output a first-level alarm signal; if the supply voltage of the second-type component is abnormal, the second-type component can output a second-level alarm signal. The manager can receive the first-level alarm signal and adjust the DC bus voltage output by the power module according to the first-level alarm signal; the manager can also receive the second-level alarm signal and adjust the set voltage output by the voltage conversion circuit according to the second-level alarm signal.

[0073] Specifically, if the DC bus voltage output by the power module is less than the voltage required for the normal operation of the first-type component, the supply voltage of the first-type component is abnormal, and the first-type component can output a first-level alarm signal. After receiving the first-level alarm signal, the manager can increase the DC bus voltage output by the power module until the supply voltage of the first-type component is normal. If the set voltage output by the voltage conversion circuit is less than the voltage required for the normal operation of the second-type component, the supply voltage of the second-type component is abnormal, and the second-type component can output a second-level alarm signal. After receiving the second-level alarm signal, the manager can increase the set voltage output by the voltage conversion circuit until the supply voltage of the second-type component is normal.

[0074] It should be noted that P = U 2 / R, where R can be the resistance of the circuit board (e.g., the first-type component or the second-type component), U 2 may be the voltage applied to the circuit board, and P can be the power consumption of the circuit board.

[0075] According to the above formula, on the basis of the normal operation of the circuit board, the smaller the voltage applied to the circuit board, the smaller the power consumption of the circuit board. Since the actual working voltage of the first-type component and / or the second-type component can be less than the standard voltage, in this embodiment, on the basis of the normal operation of the first-type component and the second-type component, the manager can reduce the DC bus voltage output by the power module and the set voltage output by the voltage conversion circuit, and can increase the DC bus voltage output by the power module when the supply voltage of the first-type component is abnormal, and can increase the set voltage output by the voltage conversion circuit when the supply voltage of the second-type component is abnormal. In this way, the voltage applied to the first-type component and the second-type component can be reduced as much as possible, the power consumption of the first-type component and the second-type component can be reduced, and the power consumption of the computing device can be reduced.

[0076] In this embodiment, the response priority of the first-level alarm signal is higher than that of the second-level alarm signal.

[0077] Specifically, if the manager receives both a Level 1 alarm signal and a Level 2 alarm signal simultaneously, it can prioritize responding to the Level 1 alarm signal. In other words, the manager can prioritize adjusting the DC bus voltage output by the power module. Thus, when both the DC bus voltage output by the power module and the set voltage output by the voltage conversion circuit need adjustment, the DC bus voltage output by the power module can be adjusted first, followed by the set voltage output by the voltage conversion circuit. This avoids repeatedly adjusting the set voltage output by the voltage conversion circuit, resulting in faster voltage regulation.

[0078] In the computing device provided in this embodiment, the manager can dynamically adjust the DC bus voltage output by the power module and the set voltage output by the voltage conversion circuit to potentially reduce the voltage applied to the first type of components and the second type of components, thereby reducing the energy consumption of the computing device.

[0079] Based on the above embodiments, the computing device may further include a digital-to-analog converter (DAC). Below, in conjunction with... Figure 3 The computing device provided in the embodiments of this application will be further described.

[0080] Figure 3 This is a schematic diagram of another computing device provided in an embodiment of this application. Please refer to... Figure 3 ,exist Figure 2 In addition to this, the computing device may also include a DAC. One end of the DAC can be connected to a manager, and the other end can be connected to a voltage conversion circuit.

[0081] The manager can adjust the set voltage output of the voltage conversion circuit via the DAC.

[0082] Specifically, when the manager adjusts the set voltage output of the voltage conversion circuit, it can send the set voltage to be adjusted (the digital signal of the set voltage to be adjusted) to the DAC. The DAC can convert the set voltage to be adjusted into a corresponding analog signal (the real voltage corresponding to the set voltage to be adjusted), and can send the converted analog signal to the voltage conversion circuit to provide a reference voltage for the voltage conversion circuit.

[0083] The voltage conversion circuit can convert the DC bus voltage into the set voltage to be adjusted based on the reference voltage output by the DAC.

[0084] In the computing device provided in this embodiment, the manager can adjust the set voltage output by the voltage conversion circuit through the DAC, thereby achieving the purpose of dynamically adjusting the set voltage output by the voltage conversion circuit.

[0085] On the basis of any of the above embodiments, the method for the manager to adjust the DC bus voltage output by the power module is described below.

[0086] In the computing device provided by the embodiments, each first-type component has a minimum working voltage; and the manager is configured to adjust the DC bus voltage output by the power module according to the minimum working voltage of each first-type component in the at least one first-type component.

[0087] Specifically, the minimum value of the DC bus voltage output by the power module is a first voltage, and the maximum value is a second voltage; if the minimum working voltage of the first-type component in the at least one first-type component is greater than the first voltage, the manager is configured to adjust the DC bus voltage output by the power module to the second voltage; if the minimum working voltage of each first-type component in the at least one first-type component is less than or equal to the first voltage, the manager is configured to adjust the DC bus voltage output by the power module according to the alarm type of the first-level alarm signal; wherein the alarm type includes at least two of the following: an emergency type, a serious type, and a slight type.

[0088] The first voltage can be the minimum power supply voltage of the power module set according to actual needs. The second voltage can be the maximum power supply voltage of the power module set according to actual needs. The embodiments do not limit the specific size of the first voltage and the second voltage, for example, the first voltage can be 11V, and the second voltage can be 12V.

[0089] The minimum working voltage of the first-type component can be the minimum voltage required for the normal operation of the first-type component. For example, the minimum working voltage of the hard disk can be the minimum voltage required for the normal operation of the hard disk.

[0090] In actual implementation, when the manager receives the first-level alarm signal, the minimum working voltage of each first-type component can be obtained. If there is a minimum working voltage of the first-type component that is greater than the first voltage, the manager can adjust the DC bus voltage output by the power module to the second voltage. If there is no minimum working voltage of the first-type component that is greater than the first voltage, the manager can adjust the DC bus voltage output by the power module according to the alarm type of the first-level alarm signal.

[0091] The manager can determine the alarm type of the first-level alarm signal according to the first type of component outputting the first-level alarm signal. Further, the manager can determine the alarm type of the first-level alarm signal according to the importance of the first type of component outputting the first-level alarm signal. If the importance of the first type of component is very important, the alarm type of the first-level alarm signal outputted by the first type of component can be an emergency type; if the importance of the first type of component is important, the alarm type of the first-level alarm signal outputted by the first type of component can be a serious type; if the importance of the first type of component is generally important, the alarm type of the first-level alarm signal outputted by the first type of component can be a slight type.

[0092] The importance of each first type of component in the computing device is different, and the importance of each first type of component can be set according to actual needs. The computing device can pre-store a correspondence between each first type of component and the importance, and the manager can determine the alarm type of the first-level alarm signal according to the correspondence between each first type of component and the importance.

[0093] For example, the correspondence between each first type of component and the importance can be as shown in Table 1:

[0094] Table 1

[0095] First class component Importance First class component 1 Generally important First class component 2 Very important …… …… First class component N Important

[0096] As shown in Table 1, the importance of the first type of component 1 can be generally important, the importance of the first type of component 2 can be very important, and the importance of the first type of component N can be important. Assuming that the first-level alarm signal is outputted by the first type of component 2, the alarm type of the first-level alarm signal can be an emergency type.

[0097] The alarm type is used to indicate the severity of the abnormality, and the severity of the abnormality corresponds to the voltage regulation step length one by one; the voltage regulation step length corresponding to the first alarm type is greater than the voltage regulation step length corresponding to the second alarm type, wherein the severity of the abnormality indicated by the first alarm type is higher than the severity of the abnormality indicated by the second alarm type.

[0098] It should be understood that the higher the importance of the first type of component, the higher the severity of the abnormality indicated by the alarm type corresponding to the first type of component.

[0099] Specifically, different alarm types can correspond to different voltage regulation step lengths. The higher the severity of the abnormality indicated by the alarm type, the greater the voltage regulation step length corresponding to the alarm type.

[0100] For example, the correspondence between the alarm type and the voltage regulation step length can be as shown in Table 2:

[0101] Table 2

[0102] Alert type Voltage regulation step size Emergency type 0.2V Critical type 0.1V Minor type 0.05V

[0103] As shown in Table 2, if the alarm type is an emergency type, the voltage adjustment step corresponding to the alarm type can be 0.2V; if the alarm type is a serious type, the voltage adjustment step corresponding to the alarm type can be 0.1V; if the alarm type is a slight type, the voltage adjustment step corresponding to the alarm type can be 0.05V.

[0104] When the manager adjusts the DC bus voltage output by the power supply module according to the alarm type of the first-level alarm signal, the first voltage adjustment step can be determined according to the alarm type of the first-level alarm signal, and used to adjust the DC bus voltage output by the power supply module according to the first voltage adjustment step and the current DC bus voltage.

[0105] For example, taking Table 2 as an example, assuming that the alarm type of the first-level alarm signal is a serious type, the first voltage adjustment step can be 0.1V.

[0106] Specifically, the sum of the first voltage adjustment step and the current DC bus voltage is a first sum value; if the first sum value is less than a second voltage, the manager is configured to adjust the DC bus voltage output by the power supply module to the first sum value; if the first sum value is greater than or equal to the second voltage, the manager is configured to adjust the DC bus voltage output by the power supply module to the second voltage.

[0107] In this embodiment, the manager can dynamically adjust the DC bus voltage output by the power supply module according to the minimum operating voltage of each first-type component and the alarm type of the first-level alarm signal. In addition, the higher the abnormal severity indicated by the alarm type of the first-level alarm signal, the larger the voltage adjustment step corresponding to the first-level alarm signal, and the faster the manager can adjust the DC bus voltage output by the power supply module to an appropriate size. In this way, the DC bus voltage output by the power supply module can be adjusted to the minimum as much as possible on the basis of ensuring the normal operation of the computing device, thereby reducing the energy consumption of the computing device.

[0108] On the basis of any of the above embodiments, the method for the manager to adjust the set voltage output by the voltage conversion circuit is described below.

[0109] In the embodiments of the present application, the alarm type of the second-level alarm signal includes at least two of the following: an emergency type, a serious type, and a slight type; the alarm type is used to indicate the abnormal severity, and the abnormal severity and the voltage adjustment step are one-to-one corresponding; the voltage adjustment step corresponding to the first alarm type is greater than the voltage adjustment step corresponding to the second alarm type, wherein the abnormal severity indicated by the first alarm type is higher than the abnormal severity indicated by the second alarm type.

[0110] The manager can determine the alarm type of the second-level alarm signal according to the second type of component outputting the second-level alarm signal. Further, the manager can determine the alarm type of the second-level alarm signal according to the importance of the second type of component outputting the second-level alarm signal. If the importance of the second type of component is very important, the alarm type of the second-level alarm signal outputted by the second type of component can be the emergency type; if the importance of the second type of component is important, the alarm type of the second-level alarm signal outputted by the second type of component can be the serious type; if the importance of the second type of component is generally important, the alarm type of the second-level alarm signal outputted by the second type of component can be the slight type.

[0111] The importance of each second type of component in the computing device is different, and the importance of each second type of component can be set according to actual needs. The computing device can pre-store a corresponding relationship between each second type of component and the importance, and the manager can determine the alarm type of the second-level alarm signal according to the corresponding relationship between each second type of component and the importance.

[0112] For example, the corresponding relationship between each second type of component and the importance can be as shown in Table 3:

[0113] Table 3

[0114] Second class component Importance Second class component 1 Generally important Second class component 2 Very important …… …… Second class component N Important

[0115] As shown in Table 3, the importance of the second type of component 1 can be generally important, the importance of the second type of component 2 can be very important, and the importance of the second type of component N can be important. Assuming that the second-level alarm signal is outputted by the second type of component 2, the alarm type of the second-level alarm signal can be the emergency type.

[0116] The corresponding relationship between the alarm type and the voltage adjustment step can be referred to Table 2, which will not be described here.

[0117] The manager can determine the second voltage adjustment step according to the alarm type of the second-level alarm signal, and can adjust the set voltage outputted by the voltage conversion circuit according to the second voltage adjustment step and the current set voltage.

[0118] Specifically, the sum of the second voltage adjustment step and the current set voltage is a second sum value, and the maximum value of the set voltage outputted by the voltage conversion circuit is a third voltage. If the second sum value is less than the third voltage, the manager is configured to adjust the set voltage outputted by the voltage conversion circuit to the second sum value. If the second sum value is greater than or equal to the third voltage, the manager is configured to adjust the set voltage outputted by the voltage conversion circuit to the third voltage.
