[0029] 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 severity of the abnormality indicated by the first alarm type is greater than the severity of the abnormality indicated by the second alarm type.

[0030] In the above scheme, the higher the severity of the abnormality indicated by the alarm type, the larger the voltage adjustment step corresponding to the alarm type, thereby achieving the purpose of performing different voltage adjustments for different first-level alarm signals.

[0031] In a possible implementation, the manager is used to determine a second voltage adjustment step according to an 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 and a current set voltage.

[0033] In a possible implementation, 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 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 used to adjust the set voltage output by the voltage conversion circuit to the second sum value;

[0035] If the second sum 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 and the third voltage, thereby achieving the purpose of determining the adjusted set voltage.

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

[0051] To facilitate 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 the power supply unit (PSU) through the AC-DC converter. The bus voltage on the server is generally around 12V.

[0053] For ease of understanding, the following Figure 1 , the application scenarios involved in the embodiments of the present application are described.

[0054] Figure 1 This is a schematic diagram of an application scenario provided by the embodiment of this application. Figure 1 The computing device may include a first type of component, a second type of component, a PSU, and a DC-DC converter. The PSU may be connected to the first type of component, and the PSU may also be connected to the second type of component via the DC-DC converter.

[0055] The computing device may be a server, a laptop computer, a desktop computer, a tablet computer, or an artificial intelligence device, etc. The server may be, for example, a graphics processing unit (GPU) server or an artificial intelligence (AI) server, etc.

[0056] The first category of components may be a board or a device on a board. When the first category of components is a device, if the device itself does not have an alarm function, an alarm may be provided through an alarm circuit or a monitoring device connected to the device. Similarly, the second category of components may include a board or a device on a board. When the second category of components is a device, if the device itself does not have an alarm function, an alarm may be provided through an alarm circuit or a monitoring device connected to the device.

[0057] The first category of components may include hard disks, Redundant Array of Independent Disks (RAID) cards, 12V powered network cards, and the like.

[0058] The second category of components may include M.2 cards, 3.3V powered network cards, temperature sensors, etc.

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

[0060] In the above scenario, the energy consumption of the computing device may include the energy consumption of supplying power to the first type of components and the second type of components.

[0061] An embodiment of the present application provides a computing device for reducing the energy consumption of the computing device.

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

[0063] Figure 2 A schematic diagram of the structure of a computing device provided in an embodiment of the present application. Figure 2 The computing device may include a power module, at least one first-type component, a voltage conversion circuit, at least one second-type component, and a manager. The number of the power module, the first-type component, the voltage conversion circuit, and the second-type component may be one or more. Figure 1This is only an exemplary description and does not constitute a limitation on the technical solutions provided in the embodiments of the present application.

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

[0065] At least one first-category component is respectively connected to the power module, and the power supply voltage of the first-category component is a DC bus voltage. That is, the first-category component may be a component in the computing device whose power supply voltage is a DC bus voltage. For example, the first-category component may be a hard disk, or a RAID, etc.

[0066] The voltage conversion circuit has an input end connected to the power module, and an output end for outputting a set voltage. The set voltage is less than the DC bus voltage. In other words, 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 this embodiment does not limit this. For example, the set voltage can be 1.8V, 3.3V or 5V.

[0068] At least one second-type component is connected to the output end of the voltage conversion circuit, and the supply voltage of the second-type component is the set voltage. That is, for example, the second-type component can be a temperature sensor or the like.

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

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

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

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

[0073] Specifically, if the DC bus voltage output by the power module is lower than the voltage required for the normal operation of the first category component, the power supply voltage of the first category component is abnormal, and the first category 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 power supply voltage of the first category component is normal. If the set voltage output by the voltage conversion circuit is lower than the voltage required for the normal operation of the second category component, the power supply voltage of the second category component is abnormal, and the second category 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 power supply voltage of the second category 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 It can 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-category component and / or the second-category component may be lower than its standard voltage, in the embodiment of the present application, on the basis of the normal operation of the first-category component and the second-category component, the manager may reduce the DC bus voltage output by the power module and the set voltage output by the voltage conversion circuit, and may increase the DC bus voltage output by the power module when the power supply voltage of the first-category component is abnormal, and may increase the set voltage output by the voltage conversion circuit when the power supply voltage of the second-category component is abnormal. In this way, the voltage applied to the first-category component and the second-category component may be reduced as much as possible, the power consumption of the first-category component and the second-category component may be reduced, and thus the power consumption of the computing device may 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 the first-level alarm signal and the second-level alarm signal at the same time, the first-level alarm signal may be responded to first. In other words, the manager may adjust the DC bus voltage output by the power module first. In this way, when both the DC bus voltage output by the power module and the set voltage output by the voltage conversion circuit need to be adjusted, the DC bus voltage output by the power module may be adjusted first, and then the set voltage output by the voltage conversion circuit may be adjusted, thereby avoiding repeated adjustment of the set voltage output by the voltage conversion circuit, and making the voltage adjustment speed higher.

[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 possibly 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 embodiment, the computing device may further include a digital-to-analog converter (DAC). Figure 3 , the computing device provided in the embodiment of the present application is further described.

[0080] Figure 3 This is a schematic diagram of another computing device provided in an embodiment of the present application. Figure 3 ,exist Figure 2 On the basis of the present invention, the computing device may further include a DAC. One end of the DAC may be connected to the manager, and the other end of the DAC may be connected to the voltage conversion circuit.

[0081] The manager can adjust the set voltage output by the voltage conversion circuit through the DAC.

[0082] Specifically, when the manager adjusts the set voltage output by the voltage conversion circuit, the set voltage to be adjusted (the digital signal of the set voltage to be adjusted) can be sent 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 a set voltage to be adjusted according to 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] Based on any of the above embodiments, a method for the manager to adjust the DC bus voltage output by the power module is described below.

[0086] In the computing device provided in the embodiment of the present application, each first-category component has a minimum operating voltage; the manager is used to adjust the DC bus voltage output by the power module according to the minimum operating voltage of each first-category component in at least one first-category component.

[0087] Specifically, the minimum value of the DC bus voltage output by the power module is the first voltage, and the maximum value is the second voltage; if the minimum operating voltage of a first-category component in at least one first-category component is greater than the first voltage, the manager is used to adjust the DC bus voltage output by the power module to the second voltage; if the minimum operating voltage of each first-category component in at least one first-category component is less than or equal to the first voltage, the manager is used 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 minor type.

[0088] The first voltage may be a minimum supply voltage of the power module set according to actual needs. The second voltage may be a maximum supply voltage of the power module set according to actual needs. This embodiment does not limit the specific values ​​of the first voltage and the second voltage. For example, the first voltage may be 11V and the second voltage may be 12V.

[0089] The minimum operating voltage of the first type of components may be the minimum voltage required for the first type of components to operate normally. For example, the minimum operating voltage of a hard disk may be the minimum voltage required for the hard disk to operate normally.

[0090] During the actual implementation, when the manager receives the first-level alarm signal, it can obtain the minimum operating voltage of each first-category component. If there is a first-category component whose minimum operating voltage 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 first-category component whose minimum operating voltage 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 may determine the alarm type of the first-level alarm signal based on the first-category component that outputs the first-level alarm signal. Further, the manager may determine the alarm type of the first-level alarm signal based on the importance of the first-category component that outputs the first-level alarm signal. If the importance of the first-category component is very important, the alarm type of the first-level alarm signal output by the first-category component may be an emergency type; if the importance of the first-category component is important, the alarm type of the first-level alarm signal output by the first-category component may be a serious type; if the importance of the first-category component is generally important, the alarm type of the first-level alarm signal output by the first-category component may be a minor type.

[0092] The importance of each first-category component in the computing device is different. The importance of each first-category component can be set according to actual needs. The corresponding relationship between each first-category component and the importance can be pre-stored in the computing device. The manager can determine the alarm type of the first-level alarm signal based on the corresponding relationship between each first-category component and the importance.

[0093] Exemplarily, the corresponding relationship between each first-category component and the importance degree may be shown in Table 1:

[0094] Table 1

[0095] First category components Importance Category I components 1 General Important Category 1 components 2 Very important …… …… First category components N important

[0096] As shown in Table 1, the importance of the first-category component 1 can be generally important, the importance of the first-category component 2 can be very important, and the importance of the first-category component N can be important. Assuming that the first-level alarm signal is output by the first-category 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 adjustment step one by one; the voltage adjustment step corresponding to the first alarm type is larger than the voltage adjustment step 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 category components, the higher the severity of the abnormality indicated by the alarm type corresponding to the first category components.

[0099] Specifically, different alarm types may correspond to different voltage adjustment step sizes. The higher the severity of the abnormality indicated by the alarm type, the larger the voltage adjustment step size corresponding to the alarm type.

[0100] Exemplarily, the corresponding relationship between the alarm type and the voltage adjustment step size may be shown in Table 2:

[0101] Table 2

[0102] Alarm Type Voltage regulation step size Emergency Type 0.2V Severe Type 0.1V Mild 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 minor 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 module according to the alarm type of the first-level alarm signal, it can determine the first voltage adjustment step according to the alarm type of the first-level alarm signal, and be used to adjust the DC bus voltage output by the power 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 severe type, the first voltage adjustment step may be 0.1V.

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

[0107] In this embodiment, the manager can dynamically adjust the DC bus voltage output by the power module according to the minimum operating voltage of each first-category component and the alarm type of the first-level alarm signal. In addition, the higher the severity of the abnormality 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 module to an appropriate value. In this way, the DC bus voltage output by the power 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] Based on any of the above embodiments, a method for the manager to adjust the set voltage output by the voltage conversion circuit is described below.

[0109] In an embodiment of the present application, the alarm types of the second-level alarm signal include at least two of the following: an emergency type, a serious type, and a minor type; the alarm type is used to indicate the severity of the abnormality, and the severity of the abnormality corresponds one-to-one to the voltage adjustment step; 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 severity of the abnormality indicated by the first alarm type is higher than the severity of the abnormality indicated by the second alarm type.

[0110] The manager may determine the alarm type of the second-level alarm signal based on the second-category component that outputs the second-level alarm signal. Further, the manager may determine the alarm type of the second-level alarm signal based on the importance of the second-category component that outputs the second-level alarm signal. If the importance of the second-category component is very important, the alarm type of the second-level alarm signal output by the second-category component may be an emergency type; if the importance of the second-category component is important, the alarm type of the second-level alarm signal output by the second-category component may be a serious type; if the importance of the second-category component is generally important, the alarm type of the second-level alarm signal output by the second-category component may be a minor type.

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

[0112] Exemplarily, the corresponding relationship between each second-category component and the importance degree may be shown in Table 3:

[0113] Table 3

[0114] Second category parts Importance Category II components 1 General Important Category II components 2 Very important …… …… Second category parts N important

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

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

[0117] The manager may determine the second voltage adjustment step length according to the alarm type of the second level alarm signal, and may adjust the set voltage output by the voltage conversion circuit according to the second voltage adjustment step length 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 output by the voltage conversion circuit is a third voltage; if the second sum value is less than the third voltage, the manager is used to adjust the set voltage output 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 used to adjust the set voltage output by the voltage conversion circuit to the third voltage.

[0119] The third voltage may be the maximum supply voltage of the voltage conversion circuit set according to actual needs. This embodiment does not limit the specific value of the third voltage, for example, the third voltage may be 5V, 3.3V or 1.8V.

[0120] In this embodiment, the manager can dynamically adjust the set voltage output by the voltage conversion circuit according to the alarm type of the second-level alarm signal.
