Description

Technical Field

[0001] The present application relates to the technical field of server power consumption testing, and in particular to a server system power consumption testing circuit, testing method and medium. Background Art

[0002] As the performance of various components such as CPU, GPU, and smart network card increases, their power consumption is also increasing, and the system power consumption of servers 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 power consumption of the entire server and evaluate the overall performance of the server to prevent the system from powering off due to excessive 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 obtained 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. The system current information can also be obtained through the current detection function pin of the server power supply, but only server power supplies that meet the new specifications will have current monitoring function pins. The current general server power supplies are not compatible and have poor applicability. Summary of the invention

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0061] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely 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 work are within the scope of protection of the present application.

[0062] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0063] In order to facilitate understanding of the solution proposed in this application, the technical terms involved in this application are explained below.

[0064] Server system power consumption (Power System, PSYS) usually refers to the overall power consumption of the server, including the power consumption of each power-consuming component (such as processor, memory, storage, network interface, disk, etc.) and the loss during transmission. Server system power consumption can be used to monitor and manage the energy efficiency of the server to ensure the operation of the system.

[0065] Programmable electronic fuse (Efuse), also known as electronic fuse, is a programmable circuit protection device to prevent abnormal conditions such as excessive current and excessive voltage from damaging the circuit. When overcurrent or overvoltage occurs in the circuit, the eFuse will detect these abnormalities through internal sensors and trigger a disconnection 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.

[0066] Common Redundant Power Supply (CRPS) is a standardized server power supply that mainly serves servers, network equipment and other high-reliability equipment to improve system availability and fault tolerance. The introduction of CRPS helps avoid the risk of system downtime caused by a single power failure and is an important technical means to improve equipment reliability and stability.

[0067] As the performance of various components such as CPU, GPU, and smart network card improves, their power consumption is also increasing, and the system power consumption of servers is also getting higher and higher. 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 power consumption of the server, evaluate the overall performance of the server, and prevent the system from powering off due to excessive instantaneous power consumption.

[0068] In order to improve the power consumption monitoring accuracy and the power consumption reading rate, the power multi-phase controller that supplies power to the central processing unit (CPU) collects the system current signal and voltage signal. The system power consumption is equal to the product of the system voltage and the system current. Then, the system power consumption information is transmitted to the CPU through the serial voltage identification protocol (Serial Voltage Identification, SVID) protocol, so that the CPU can obtain PSYS information. The method of obtaining power consumption information through the SVID bus is faster than the traditional method of obtaining power consumption through the power management and monitoring protocol (Power Management Bus, PMBUS). The CPU can adjust its own power consumption at a faster speed to achieve the goal of controlling the system power consumption. If the PSYS power consumption is lower than the maximum output power consumption of the CRPS, the CPU can continue to increase the frequency, increase power consumption, and improve performance; if the PSYS power consumption exceeds the maximum output power consumption of the CRPS, the CPU reduces the frequency, reduces the CPU power consumption, and reduces performance, thereby avoiding the system power failure caused by the overcurrent protection triggered by the CRPS power supply.

[0069] PSYS power consumption can be determined by collecting system voltage information and system current information. Among them, system voltage information is relatively easy to obtain. Voltage acquisition is performed at the input end of the board, and the voltage signal is connected to the voltage acquisition pin of the power multi-phase controller. System current signals are more difficult to obtain. There are currently two main methods:

[0070] 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. 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 multi-phase controller, so that the CPU can obtain PSYS information. However, Ishare is a current sharing bus between multiple CRPSs. Its function is to share current signals between CRPSs to achieve current sharing. However, its own 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 CRPSs of different powers. A server needs to support CRPS power supplies of different powers. This requires designing different parameters on the board to match different CRPSs, which brings great difficulty to design and testing, and will further reduce the accuracy of power consumption monitoring.

[0071] The second method is to use the current monitoring function pin of CRPS. The pin voltage is proportional to the output current. By connecting this pin to the power multi-phase controller, the CPU can obtain PSYS information. However, only CRPS that meet the new specifications will have a current monitoring function pin. The current common CRPS power supply is not compatible with the design and has poor applicability.

[0072] Based on the above problems, the embodiment of the present application provides a server system voltage test circuit, a test method and a medium, wherein 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 to the server power supply, the power input terminal of the first electrical component and the first input terminal of the control unit respectively, and is used to collect the branch current between the server power supply and the power input terminal of the first electrical component, and output the first voltage of the power supply terminal of the first electrical component based on the branch current. Each second voltage acquisition circuit is electrically connected to the server power supply, the power input terminal of the second electrical component and the first input terminal of the control unit respectively, and is used to collect the second voltage of the power input terminal of the second electrical component. The first electrical component is an electrical component protected by an electronic fuse, and the second electrical component is an electrical component not protected by an electronic fuse. The system voltage acquisition circuit is electrically connected to the server power supply and the second input terminal of the control unit respectively, and is used to collect the system voltage of the server. Further, the control unit determines the system power consumption of the server according to the input first voltage, the second voltage and the system voltage. Specifically, the system current corresponding to the first voltage and the second voltage can be determined by the relationship between the voltage and the current, and then the system power consumption of the server can be determined by the system current and the system voltage. Through the above method, the voltage acquisition circuit collects the voltage by designing a first voltage acquisition circuit for the first power-consuming component and a second voltage acquisition circuit for the second power-consuming component, and then the system current is determined based on the corresponding relationship between the voltage and the circuit. The test circuit uses the existing circuit components on the board, with little modification to the board and high test accuracy.

[0091] In some embodiments, the 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 the ratio of the number of electronic fuses in the second target voltage acquisition circuit to the number of 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.

[0092] 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 as an example, 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, wherein 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. According to 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), then R11 / R13=1 / 2.

[0093] In some embodiments, the resistance of the third resistor is calculated by: calculating a first product of the resistance of the target first resistor, the resistance of the second resistor, the gain of the voltage amplifier, and the number of target electronic fuses, and calculating a second product of the resistance of the grounding resistor of the target electronic fuse and the current scaling ratio of the target electronic fuse; and taking the ratio of the first product to the second product as the resistance of the third resistor;

[0094] The target first resistor and the target electronic fuse are the first resistor and the electronic fuse in any one of the M first voltage acquisition circuits.

[0095] Taking the target first resistor and the target electronic fuse as the first resistor and the electronic fuse in the first voltage acquisition circuit 110 as an example, R3=(R11×R2×T 放 ×N1) / (R 地 ×T 缩 ), wherein 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, T 放 represents the gain of the voltage amplifier, N1 represents the number of electronic fuses in the first voltage acquisition circuit 110, and R 地 Indicates the grounding resistance of the electronic fuse, T 缩 Indicates the current scaling ratio of the electronic fuse in the first voltage acquisition circuit 110 .

[0096] In some embodiments, the corresponding relationship between the configured voltage and current may be determined in the following manner:

[0097] Determine a first voltage and current correspondence relationship of a first voltage acquisition circuit, and a second voltage and current correspondence relationship of a second voltage acquisition circuit;

[0098] The voltage-current correspondence relationship when the first voltage-current correspondence relationship and the second voltage-current correspondence relationship are equal is used as the configured voltage-current correspondence relationship.

[0099] Specifically, for M first voltage acquisition circuits, it is assumed that the first first voltage acquisition circuit includes a Efuses, and the corresponding first resistor is R11; the second first voltage acquisition circuit includes b Efuses, and the corresponding first resistor is R12, and so on; then the corresponding relationship between voltage and current in the first voltage acquisition circuit is expressed as: X=(R12 / / R13 / / R14... / / Rm) / R11*K / a, wherein R12 / / R13 / / R14... / / Rm is used to represent the parallel value of the first resistors in other first voltage acquisition circuits except the first first voltage acquisition circuit; K is the current scaling ratio of the current monitoring pin of the Efuse chip, which is generally 10uA / A.

[0100] For N second voltage acquisition circuits, assuming that the second resistor in the first second voltage acquisition circuit is represented by Rd, and the corresponding resistor is RD; the second resistor in the second second voltage acquisition circuit is represented by Re, and the corresponding resistor is RE, and so on; then in the second voltage acquisition circuit, the corresponding relationship between voltage and current is expressed as Y=(RE / / RF...) / RD*B, where RE / / RF... represents the parallel value of the second resistors in other second voltage acquisition circuits except the first second voltage acquisition circuit, and B is the amplification factor of the voltage amplifier in the first second voltage acquisition circuit.

[0101] When X=Y, the corresponding relationship between voltage and current of the M first voltage acquisition circuits and the N second voltage acquisition circuits is the same. Further, the corresponding relationship between voltage and current configured in the power multi-phase controller can be expressed as: Z=X*C, where C is the gain of the operational amplifier.

[0102] The embodiment of the present application provides a test circuit for power consumption of a server system. A low-cost test circuit with high monitoring accuracy is designed without making major adjustments to the board layout. Figure 3 As shown, it is a circuit diagram of the test circuit. Taking the electronic fuse as Efuse, the second resistor as a precision resistor, and the control unit including a power multi-phase controller and a central processing unit as an example, the specific contents of the test circuit are described in detail below.

[0103] According to the types of electrical components in the server system and the system power supply topology, the electrical components in the server system are classified into two categories: one is the electrical components that require an Efuse to be placed at the input end. This part can directly use the existing circuits on the board without adding additional Efuse; the other part is the electrical components that do not require an Efuse to be placed at the input end. This part requires placing precision resistors at the power supply entrance of the electrical components to monitor power consumption through precision resistors.

[0104] Specifically, in the distributed Efuse protection solution used on the motherboard, the number of Efuses in each group may be 1 or more in parallel, and the number is determined by the load current. Figure 3 In the 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 scaling ratio of the current monitoring pin of each Efuse chip is the same, and the resistance of the current monitoring pin to ground is the same. As an example, the current scaling ratio of the current monitoring pin of the Efuse chip is 10uA / A, and the resistance of the current monitoring pin of each chip to ground is set to 2Kohm; after the three groups of Efuse chips are designed in parallel, the relationship between the voltage and current of the current monitoring pin is: 20 / a mV / A, 20 / b mV / A, 20 / c mV / A.

[0105] For electrical components on the motherboard that do not use the Efuse chip, a precision resistor can be placed at the input end of the power supply inlet to collect the voltage difference across the precision resistor. The current I flowing through the precision resistor = voltage difference V / precision resistor resistance Rd. In some scenarios, in order to reduce the loss on the precision resistor, a precision resistor with a small resistance can be selected. At this time, the signal collected on the resistor (current scaling ratio) is very small and needs to be amplified. The voltage difference on the precision resistor is transmitted to the voltage amplifier PU1. Among them, the voltage amplifier is a voltage amplifier with a fixed amplification ratio. As an example, a 50x chip can be selected. Therefore, the voltage and current relationship corresponding to the precision resistor is: Rd*50mV / A;

[0106] At the input end of the board, the voltage signal is collected and connected to the power multi-phase controller through R_7 to obtain the system voltage signal.

[0107] In some embodiments, the ratio of voltage and current of the signals output by each group of Efuse and precision resistor is different, 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 the opposite ratio, that is, R_1 / R_2 / R_3 needs to be set to: the ratio of the opposite relationship between the voltage and current of the current monitoring pin, and the setting ratio is: R_1*a=R_2*b=R_3*c; the resistance value of the series resistor R4 at the back end of PU1 is also set in the opposite ratio, that is: R_1 / (20 / a)=R_4 / (Rd*50); After the resistance value of R_1 / R_2 / R_3 / R_4 is selected, the matching of the voltage signals of each part (that is, the voltage expression form of the current signal when calculating the power) is completed, and the groups of signals are connected together to complete the voltage signal accumulation. At this time, the same current is applied to any part, and the output voltage is the same.

[0108] Furthermore, after each group of signals is connected together, the ratio of the voltage and current signals obtained, Gain, is very low. The more Efuse or precision resistor groups are grouped, the smaller the Gain. If the Gain is too small, the voltage delivered to the power controller will be relatively low. Too low a voltage signal will also affect the monitoring accuracy, so the Gain can be amplified. PU2 is an operational amplifier with an amplification factor of: R_6 / R_5+1. After the amplification, the Gain signal is output to the power multi-phase controller, and the power controller obtains the system voltage signal information used to describe the system current. Furthermore, the power controller determines the system current based on the corresponding relationship between voltage and current.

[0109] The power controller obtains system voltage and system current information. The power controller and the central controller CPU are connected through the serial voltage identification protocol SVID bus. Through the SVID protocol, the CPU obtains the system power consumption information of the current system and the system's CRPS output capability information. The CPU can adjust its own power consumption accordingly and perform dynamic CPU power consumption regulation.

[0110] Through the above test circuit, using the existing Efuse solution on the motherboard, only a small amount of precision resistors and circuit elements need to be added to realize the test of server system power consumption, and the cost is relatively low. Secondly, the newly added device package in the test circuit of this application is relatively small, with low requirements for placement, and occupies a small area of ​​the board, which will not affect the overall layout and wiring of the board. In addition, the Efuse chip and precision resistors have high precision, coupled with the influence of wiring on precision, the accuracy of the power controller converting analog signals into digital signals, and the accuracy of reading system power consumption, can meet the accuracy requirements of system power consumption testing as a whole, and the test accuracy is relatively high.

[0111] Based on the same technical concept, the present application embodiment provides a test method, which is applied to the test circuit described above. Figure 4 As shown, the test method includes the following steps:

[0115] S404: Determine the system power consumption of the server according to the acquired first voltages acquired by the M first voltage acquisition circuits, the second voltages acquired by the N second voltage acquisition circuits, and the system voltage.

[0116] In some embodiments, when determining the system power consumption of a server based on the first voltages acquired by M first voltage acquisition circuits, the second voltages acquired by N second voltage acquisition circuits, and the system voltage, it is specifically implemented in the following manner: determining the sum of the first voltages acquired by the M first voltage acquisition circuits and the sum of the second voltages acquired by the N second voltage acquisition circuits; determining the first current corresponding to the sum of the first voltages and the second current corresponding to the sum of the second voltages based on the correspondence between the configured voltages and currents; and determining the system power consumption of the server based on the first current, the second current, and the system voltage.

[0117] In some scenarios, the sum of the first voltage and the sum of the second voltage may be added together to obtain a total voltage, and then based on the correspondence between voltage and current, the system current corresponding to the total voltage may be determined, and then the system power consumption of the server may be determined by the system current and the system voltage.

[0118] In some embodiments, the corresponding relationship between the configured voltage and current is determined by:

[0119] Determine a first voltage and current correspondence relationship of a first voltage acquisition circuit, and a second voltage and current correspondence relationship of a second voltage acquisition circuit;

[0120] The voltage-current correspondence relationship when the first voltage-current correspondence relationship and the second voltage-current correspondence relationship are equal is used as the configured voltage-current correspondence relationship.

[0121] Specifically, for M first voltage acquisition circuits, assuming that the first first voltage acquisition circuit includes a Efuses, the corresponding first resistor is R11; the second first voltage acquisition circuit includes b Efuses, the corresponding first resistor is R12, and so on; then the corresponding relationship between voltage and current in the first voltage acquisition circuit is expressed as: X=(R12 / / R13 / / R14... / / Rm) / R11*K / a, wherein R12 / / R13 / / R14... / / Rm is used to represent the parallel value of the first resistors in other first voltage acquisition circuits except the first first voltage acquisition circuit; K is the basic corresponding relationship between voltage and current of the Efuse chip, generally 10uA / A.

[0122] For N second voltage acquisition circuits, assuming that the second resistor in the first second voltage acquisition circuit is represented by Rd, and the corresponding resistor is RD; the second resistor in the second second voltage acquisition circuit is represented by Re, and the corresponding resistor is RE, and so on; then in the second voltage acquisition circuit, the corresponding relationship between voltage and current is expressed as Y=(RE / / RF...) / RD*B, where RE / / RF... represents the parallel value of the second resistors in other second voltage acquisition circuits except the first second voltage acquisition circuit, and B is the amplification factor of the voltage amplifier in the first second voltage acquisition circuit;

[0123] When X=Y, the corresponding relationship between voltage and current of the M first voltage acquisition circuits and the N second voltage acquisition circuits is the same. Further, the corresponding relationship between voltage and current configured in the power multi-phase controller can be expressed as: Z=X*C, where C is the gain of the operational amplifier.
