[0002] With the performance improvement of various components such as CPU, GPU, smart network card, etc., the power consumption is also increasing, and the system power consumption of the server is also increasing. Due to the increase of power consumption, especially the instantaneous power consumption, a more accurate and faster power consumption reading method is needed to better monitor and manage the server system power consumption, evaluate the overall performance of the server, and prevent the system from being powered off due to high instantaneous power consumption. The system power consumption can be determined by collecting system voltage information and system current information. The system current information can be collected through the Ishare function pin of the server power supply. The voltage of the Ishare pin is proportional to the output current, but the accuracy is poor.

[0059] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0060] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0061] It should be noted that the relational terms, such as first and second, and the like, are used solely to distinguish one from another entity or action, without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, an element preceded by "comprises... " does not exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the recited element.

[0062] In order to facilitate the understanding of the scheme proposed in the present application, the technical terms involved in the present application are explained below.

[0063] Server system power (PSYS) generally refers to the overall power consumption of a server, including the power consumption of various power components (such as processors, memories, storage, network interfaces, disks, etc.) and the loss in the transmission process. Server system power can be used to monitor and manage the energy efficiency of the server to ensure the operation of the system.

[0064] Programmable electronic fuse (Efuse), also known as electronic fuse, is a programmable circuit protection device to prevent damage to the circuit caused by excessive current, voltage and other abnormal conditions. When overcurrent or overvoltage occurs in the circuit, eFuse will detect these abnormalities through internal sensors and trigger a disconnect action to quickly cut off the power supply to avoid overload damage. Unlike traditional fuses, electronic fuses can self-disconnect and repair through electronic control when a fault occurs, without the need to replace physical components.

[0065] Common redundant power supply (CRPS) is a standardized design of server power supply, mainly serving servers, network devices and other high-reliability devices to improve system availability and fault tolerance. The introduction of CRPS helps to avoid the risk of system downtime caused by single power failure, and is an important technical means to improve device reliability and stability.

[0066] With the performance improvement of various components such as CPU, GPU, smart network card, etc., the power consumption is also increasing, and the system power consumption of the server is also increasing. Due to the increase in power consumption, especially instantaneous power consumption, a more accurate and faster power consumption reading method is needed to better monitor and manage the overall power consumption of the server, evaluate the overall performance of the server, and prevent system power failure caused by excessive instantaneous power consumption.

[0067] In order to improve the power consumption monitoring accuracy and the power consumption reading rate, the system current signal and the voltage signal are collected through a power supply multiphase controller for a central processing unit (CPU), the system power consumption is equal to the product of the system voltage and the system current, the system power consumption information is transmitted to the CPU through a serial voltage identification (SVID) protocol, and thus the CPU obtains the PSYS information. The method of obtaining the power consumption information through the SVID bus is faster than the traditional method of obtaining the power consumption through a power management bus (PMBUS), the CPU can adjust the power consumption at a faster speed, and the target of controlling the system power consumption is achieved. If the PSYS power consumption is lower than the maximum output power consumption of the CRPS, the CPU can continue to increase the frequency and increase the power consumption to improve the performance; if the PSYS power consumption exceeds the maximum output power consumption of the CRPS, the CPU reduces the frequency and reduces the CPU power consumption to reduce the performance, so as to avoid the system power failure and shutdown caused by the over-current protection triggered by the CRPS power supply.

[0068] The PSYS power consumption can be determined by collecting the system voltage information and the system current information. The system voltage information is relatively easy to obtain, and the voltage signal is connected to the voltage collection pin of the power supply multiphase controller at the input end of the board card. The system current signal is relatively difficult to obtain, and there are currently two methods:

[0069] The first method is to use the Ishare function pin of the CRPS power supply. The Ishare pin is usually used as the current sharing bus of the CRPS, and the voltage of the Ishare pin is proportional to the output current. The Ishare signal is converted into a voltage signal and transmitted to the power supply multiphase controller, so that the CPU obtains the PSYS information. However, the Ishare is a current sharing bus among multiple CRPS, and its function is to share the current signal among the CRPS to achieve current sharing. However, its accuracy is poor and cannot meet the accuracy requirements of PSYS. In addition, the conversion ratio of the Ishare pin voltage and current is different for different power CRPS. A server needs to support different power CRPS, which requires different parameters to be designed on the board card to match different CRPS, which brings great difficulty to design and test, and further reduces the accuracy of power consumption monitoring.

[0070] The second method is to use the current monitoring function pin of the CRPS, the pin voltage is proportional to the output current, connect this pin to the multi-phase controller of the power supply, and the CPU can obtain the PSYS information. However, only the CRPS meeting the new specification has the current monitoring function pin, and the currently common CRPS power supply cannot be designed compatibly, and the applicability is poor.

[0071] Based on the above problems, the embodiments of the present application provide a server system voltage test circuit, a test method and a medium. The test circuit includes M first voltage acquisition circuits, N second voltage acquisition circuits, a system voltage acquisition circuit and a control unit. Each first voltage acquisition circuit is electrically connected with a server power supply, a power input end of a first power consuming component and a first input end of the control unit, respectively, for acquiring a branch current between the server power supply and the power input end of the first power consuming component, and outputting a first voltage of the power input end of the first power consuming component based on the branch current. Each second voltage acquisition circuit is electrically connected with the server power supply, a power input end of a second power consuming component and a first input end of the control unit, respectively, for acquiring a second voltage of the power input end of the second power consuming component. The first power consuming component is a power consuming component with electronic fuse protection, and the second power consuming component is a power consuming component without electronic fuse protection. The system voltage acquisition circuit is electrically connected with the server power supply and a second input end of the control unit, respectively, for acquiring a system voltage of the server. Further, the control unit determines the system power consumption of the server according to the input first voltage, second voltage and system voltage. Specifically, the system current corresponding to the first voltage and the second voltage can be determined through the relationship between voltage and current, and then the system power consumption of the server is determined through the system current and the system voltage. Through the above method, the voltage acquisition circuit is designed for the first power consuming component and the second power consuming component to acquire the voltage, and then the system current is determined based on the corresponding relationship between voltage and current. The test circuit uses the existing circuit elements on the board card, has less changes to the board card, and has high test precision.

A second terminal of the fifth resistor R601 is electrically connected to a power terminal of the operational amplifier 603.

[0090] In some embodiments, a ratio of the first resistor in the first target voltage acquisition circuit to the first resistor in the second target voltage acquisition circuit is equal to a ratio of a number of the electronic fuses in the second target voltage acquisition circuit to a number of the electronic fuses in the first target voltage acquisition circuit. The first target voltage acquisition circuit and the second target voltage acquisition circuit are any two of the M first voltage acquisition circuits.

[0091] As an example, taking the first target voltage acquisition circuit as the first voltage acquisition circuit 110 and the second target voltage acquisition circuit as the first voltage acquisition circuit 130, the ratio of the first resistor R111 in the first voltage acquisition circuit 110 to the first resistor R131 in the first voltage acquisition circuit 130 is equal to the ratio of the number of electronic fuses in the first voltage acquisition circuit 130 to the number of electronic fuses in the first voltage acquisition circuit 110. For example, R11 / R13 = N3 / N1, where R11 represents the resistance value of the first resistor R111, R13 represents the resistance value of the first resistor R131, N3 represents the number of electronic fuses in the first voltage acquisition circuit 130, and N1 represents the number of electronic fuses in the first voltage acquisition circuit 110. Based on the above example, the first voltage acquisition circuit 130 includes one electronic fuse 132, and the first voltage acquisition circuit 110 includes two electronic fuses (electronic fuse 112 and electronic fuse 113), so R11 / R13=1 / 2.

[0092] In some embodiments, the resistance value of the third resistor is calculated by: calculating a first product of the resistance value of the target first resistor, the resistance value of the second resistor, the amplification factor of the voltage amplifier, and the number of target electronic fuses, and calculating a second product of the grounding resistance of the target electronic fuse and the current scaling factor of the target electronic fuse; and taking the ratio of the first product to the second product as the resistance value of the third resistor.

[0093] Among them, the target first resistor and the target electronic fuse are the first resistor and electronic fuse in any one of the M first voltage acquisition circuits.

[0094] Taking the target first resistor and the target electronic fuse as the first resistor and electronic fuse in the first voltage acquisition circuit 110 as an example, R3 = (R11 × R2 × Tamplifier × N1) / (Rground × Tscaling), where R11 represents the resistance value of the first resistor R111 in the first voltage acquisition circuit 110, R2 represents the resistance value of the second resistor, Tamplifier represents the amplification factor of the voltage amplifier, N1 represents the number of electronic fuses in the first voltage acquisition circuit 110, Rground represents the grounding resistance value of the electronic fuse, and Tscaling represents the current scaling ratio of the electronic fuse in the first voltage acquisition circuit 110.

[0095] In some embodiments, the correspondence between the configured voltage and current can be determined in the following manner:

[0096] Determine the first voltage and current correspondence of the first voltage acquisition circuit, and the second voltage and current correspondence of the second voltage acquisition circuit;

[0097] The voltage and current corresponding relationship when the first voltage and current corresponding relationship and the second voltage and current corresponding relationship are equal is taken as the configured voltage and current corresponding relationship.

[0098] Specifically, for the M first voltage acquisition circuits, it is assumed that the first first voltage acquisition circuit includes a Efuse, and the corresponding first resistance is R11; the second first voltage acquisition circuit includes b Efuses, and the corresponding first resistance is R12; and so on; and the voltage and current corresponding relationship in the first voltage acquisition circuit is represented as: X=(R12 / / R13 / / R14... / / Rm) / R11 K / a, wherein R12 / / R13 / / R14... / / Rm is used to represent the parallel value of the first resistances in the other first voltage acquisition circuits except the first first voltage acquisition circuit; and K is the current monitoring pin current scaling ratio of the Efuse chip, and is generally 10uA / A.

[0099] For the N second voltage acquisition circuits, it is assumed that the second resistance in the first second voltage acquisition circuit is represented as Rd, and the corresponding resistance is RD; the second resistance in the second second voltage acquisition circuit is represented as Re, and the corresponding resistance is RE; and so on; and the voltage and current corresponding relationship in the second voltage acquisition circuit is represented as Y=(RE / / RF...) / RD B, wherein RE / / RF... represents the parallel value of the second resistances in the other second voltage acquisition circuits except the first second voltage acquisition circuit, and B is the amplification multiple of the voltage amplifier in the first second voltage acquisition circuit.

[0100] When X=Y, that is, the voltage and current corresponding relationship of the M first voltage acquisition circuits and the N second voltage acquisition circuits are respectively the same. Further, the configured voltage and current corresponding relationship in the multi-phase power supply controller can be represented as: Z=X C, C is the amplification multiple of the operational amplifier.

[0101] Embodiments of the application provide a test circuit for server system power consumption, which is low in cost and high in monitoring precision without making great adjustment to the layout of a board card. Figure 3 As shown in the figure, it is a circuit schematic diagram of the test circuit, takes an electronic fuse as the Efuse, takes a precision resistor as the second resistance, and takes a power supply multi-phase controller and a central processing unit as the control unit, and the specific content of the test circuit is described in detail below.

[0102] According to the type of the power consumption components in the server system and the system power supply topology, the power consumption components in the server system are classified, and some of the power consumption components need to be placed with Efuse at the input end, and this part can directly use the existing circuit on the board, without additional Efuse; another part of the power consumption components does not need to be placed with Efuse at the input end, and this part needs to be placed with a precision resistor at the power supply inlet of the power consumption component, and the power consumption is monitored through the precision resistor.

[0103] Specifically, the distributed Efuse protection scheme used on the mainboard, the number of each group of Efuse may be one or more in parallel, and the number is determined according to the load current size. Figure 3 For example, there are three groups of Efuse chips in the system, and the number of Efuse chips used in each group is a, b, and c, respectively. The current monitoring pin current scaling ratio of each Efuse chip is the same, and the current monitoring pin resistance to ground is the same. As an example, the current monitoring pin current scaling ratio of the Efuse chip is 10uA / A, and the current monitoring pin resistance to ground of each chip is set to 2Kohm. After the parallel design of the three groups of Efuse chips, the current monitoring pin voltage and current relationship is respectively: 20 / a mV / A, 20 / b mV / A, and 20 / c mV / A.

[0104] For the power consumption components on the mainboard that do not use Efuse chips, a precision resistor can be placed at the input end of the power supply inlet, the voltage difference across the precision resistor is collected, and the current flowing through the precision resistor is I=voltage difference V / precision resistor resistance Rd. In some scenarios, in order to reduce the loss on the precision resistor, a resistor with small resistance value can be selected, at this time the signal (current scaling ratio) collected on the resistor is very small, and needs to be amplified. The voltage difference on the precision resistor is transmitted to the voltage amplifier PU1. The voltage amplifier is a fixed amplification ratio voltage amplifier, as an example, a 50 times chip can be selected. Therefore, the voltage and current relationship corresponding to the precision resistor is: Rd 50 mV / A;

[0105] At the input end of the board, the voltage signal is collected and connected to the power supply multiphase controller through R_7 to obtain the system voltage signal.

[0106] In some embodiments, the signal output by each group of Efuse and precision resistor has a different voltage and current ratio, so these signals cannot be directly connected together. A resistor with a large resistance value needs to be connected in series on each group of signals. According to the signal size, the resistance value is set in inverse proportion, that is, R_1 / R_2 / R_3 needs to be set as: the inverse proportion of the current monitoring pin voltage and current relationship, and the setting proportion is: R_1 a=R_2 b=R_3 c;PU1 back-end series resistance value R4 value is also set in the opposite proportion, that is: R_1 / (20 / a)=R_4 / (Rd 50); R_1 / R_2 / R_3 / R_4 resistance value is selected, that is, the voltage signal (i.e. the voltage form of the current signal when calculating the power) of each part is matched, each group of signals is connected together, and the voltage signal is accumulated. At this time, the same current is applied to any part, and the output voltage is the same.

[0107] Further, after each group of signals is connected together, the voltage and current signal ratio Gain is very low. The more the Efuse or precision resistance groups, the smaller the Gain. If the Gain is too small, the voltage delivered to the power supply controller will be relatively low. Too low voltage signal will also affect the monitoring accuracy, so the Gain can be amplified. PU2 is an operational amplifier, and the amplification factor is: R_6 / R_5+1. After amplification, the Gain of the signal is output to the power supply multiphase controller, and the power supply controller obtains the system voltage signal information used to represent the system current. Further, the power supply controller determines the system current according to the corresponding relationship between the voltage and the current.

[0108] The power supply controller obtains the system voltage and system current information. The power supply controller and the central controller CPU are connected through the serial voltage identification protocol SVID bus. Through the SVID protocol, the CPU obtains the current system power consumption information and the system CRPS output capability information. The CPU can adjust its own power consumption according to the information, and perform CPU power consumption dynamic adjustment.

[0109] Through the above test circuit, using the existing Efuse scheme on the mainboard, a small amount of precision resistance and circuit elements need to be added to realize the test of the server system power consumption, which has low cost. Secondly, the newly added devices in the test circuit of the application have small package, low requirement for placement position, and small occupation of board area, which will not affect the overall layout and wiring of the board. In addition, the precision of the Efuse chip and the precision resistance is high. In addition to the influence of wiring on the precision, the precision of the power supply controller in converting the analog signal into a digital signal and the precision in reading the system power consumption can meet the precision requirement of the system power consumption test, and the test precision is high.

[0110] Based on the same technical concept, the embodiment of the application provides a test method applied to the test circuit described above, as shown in Figure 4 The test method comprises the following steps:

[0111] S401, for M first voltage acquisition circuits, acquiring a branch current between a server power supply and a power input end of a first power-consuming component acquired by the first voltage acquisition circuit, and outputting a first voltage of the power supply end of the first power-consuming component based on the branch current;

[0112] S402, for N second voltage acquisition circuits, acquiring the second voltage of the power input end of the second power consumer collected by the second acquisition voltage acquisition circuit;

[0113] S403, acquiring a system voltage acquisition circuit electrically connected to the second input end of the server power supply and the control unit respectively, for collecting the system voltage of the server;

[0114] S404, determining the system power consumption of the server according to the first voltage collected by the M first voltage acquisition circuits, the second voltage collected by the N second voltage acquisition circuits, and the system voltage.

[0115] In some embodiments, when determining the system power consumption of the server according to the first voltage collected by the M first voltage acquisition circuits, the second voltage collected by the N second voltage acquisition circuits, and the system voltage, the following method is used: determining the sum of the first voltage collected by the M first voltage acquisition circuits and the sum of the second voltage collected by the N second voltage acquisition circuits; determining the first current corresponding to the sum of the first voltage and the second current corresponding to the sum of the second voltage based on the configured voltage and current correspondence; and determining the system power consumption of the server according to the first current, the second current, and the system voltage.

[0116] In some scenarios, the sum of the first voltage and the sum of the second voltage can be added to obtain the total voltage, and then based on the correspondence between the voltage and the current, the system current corresponding to the total voltage is determined, and then the system power consumption of the server is determined through the system current and the system voltage.

[0117] In some embodiments, the configured voltage and current correspondence is determined as follows:

[0118] determining the first voltage and current correspondence of the first voltage acquisition circuit and the second voltage and current correspondence of the second voltage acquisition circuit;

[0119] the voltage and current correspondence when the first voltage and current correspondence and the second voltage and current correspondence are equal is taken as the configured voltage and current correspondence.

[0120] Specifically, for the M first voltage acquisition circuits, it is assumed that the first first voltage acquisition circuit includes a Efuse, and the corresponding first resistance is R11; the second first voltage acquisition circuit includes b Efuses, and the corresponding first resistance is R12; and so on; then the correspondence between the voltage and the current in the first voltage acquisition circuit is represented as: X=(R12 / / R13 / / R14... / / Rm) / R11 K / a, where R12 / / R13 / / R14... / / Rm is used to represent the parallel value of the first resistor in the other first voltage acquisition circuits besides the first first voltage acquisition circuit; K is the basic voltage-current correspondence of the Efuse chip, which is generally 10uA / A.

[0121] For N second voltage acquisition circuits, assuming the second resistor in the first second voltage acquisition circuit is denoted as Rd, and the corresponding resistance is RD; the second resistor in the second second voltage acquisition circuit is denoted as Re, and the corresponding resistance is RE, and so on; then the relationship between voltage and current in the second voltage acquisition circuit is expressed as Y = (RE / / RF...) / RD B, where RE / / RF... represents the parallel value of the second resistor in the other second voltage acquisition circuits besides the first second voltage acquisition circuit, and B is the amplification factor of the voltage amplifier in the first second voltage acquisition circuit;

[0122] When X=Y, the voltage and current correspondences are identical for the M first voltage acquisition circuits and the N second voltage acquisition circuits. Furthermore, the voltage and current correspondence configured in the multi-phase power controller can be expressed as: Z=X C, where C is the amplification factor of the operational amplifier.
