It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In an embodiment, referring to fig. 1, the present invention provides a method for testing current sharing of a server power module, including the following steps:
s100, responding to the power-on of the server, acquiring the number of PSUs of the power supply module of the server and the rated output power of each PSU;
s200, calling a pressurizing tool to adjust the load value of the electric consumption device of the server, and acquiring the actual output power of each PSU to obtain a first output power; preferably, the electrical consumer comprises a CPU and/or a memory;
the stress tool is a stress tool of a Linux operating system and is used for adjusting the working state of the device, the load refers to the utilization rate of the device, and for example, if all the performances of the CPU are 100% and are not used as 0%, the stress tool can use the working state of the CPU as 10% and other arbitrary values. Similarly, in the specific implementation process, the stress pressurizing tool of the memory using the Linux operating system may be adjusted to any value such as the usage rate of 30%.
S300, determining a first error rate according to the rated output power of each PSU and the corresponding first output power;
s400, calling a power-on/off command of the ipmitool to execute power-on/off for a plurality of times, and obtaining the actual output power of each PSU again to obtain a second output power;
the IPMI is a short name of an Intelligent Platform Management Interface, and represents an Intelligent Platform Management Interface, and the ipmitool is a built-in IPMI command tool installed in a Linux operating system on a server and can perform interactive communication and remote monitoring on the power module.
S500, determining a second error rate according to the rated output power of each PSU and the corresponding second output power;

According to the server power module current-sharing test method, the load value of the power consumption device of the server is adjusted by calling the pressurizing tool, the actual output power of each PSU is obtained to obtain the first output power, the power on/off command of the ipmitool is called to execute the power on/off for a plurality of times, the actual output power second output power of each PSU is obtained again, the corresponding error rate is calculated through the preset formula, the automatic execution of the server current-sharing test is realized, the working time of a large number of testers is saved, the production cost is reduced, and the test accuracy and efficiency are improved.
In another embodiment, based on the foregoing embodiment, the method for testing current sharing of a server power module in this embodiment further includes the following steps:
and S700, in response to the second error rate, calling a pressurizing tool to unload the load of the power consumption device on the server.
Wherein, the load unloading refers to adjusting the load of the power consumption device to 0%, for example, if the load of the CPU is also adjusted to 10%, then the load unloading refers to adjusting the load of the CPU back to 0%; similarly, assuming that the electrical consumer includes a CPU and a memory, performing the load unloading operation requires that the load of the CPU and the load of the memory are both adjusted back to the load value equal to 0%.
In yet another embodiment, the method further comprises the steps of:
s800, in response to the completion of load unloading, returning to the step of calling the load value of the electric consumption device of the pressurizing tool adjusting server again, and acquiring the actual output power of each PSU to obtain a first output power; wherein, the load values of the pressurizing tool adjusted in two times are different.
Specifically, for example, if the stress pressurization tool adjusts the load value of the CPU to 10% in the first step S200, the load value of the CPU is adjusted to 0% after the step S600 is completed; returning to step S200 again, the load of the CPU is adjusted again by the stress compression tool so that the CPU load value is adjusted from 0% to 20% again, and steps S300 to S500 are executed for the next time. It should be noted that, of course, the step S200 may be repeated after the current sharing test is performed, and considering that the current sharing test of the power module usually only needs to measure two states of the power consuming device, the step S200 to the step S500 are performed twice, and the number of times of the return execution may be increased when a more accurate test is required.

According to the method for testing the current sharing of the power module of the server, the error rates obtained by calculation each time are combined with the preset values corresponding to different testing situations to be compared, the error rates are automatically classified, the testing results are simply, visually and conveniently obtained, manual calculation or statistics are not needed, the time for manually processing the testing data is greatly saved, the testing efficiency is remarkably improved, and the method has high accuracy.

In another embodiment, to facilitate understanding of the technical solution of the present invention, please refer to fig. 2, which is a flowchart illustrating a CPU as an electrical consumption device, which is implemented by using a common Bash Shell statement of a Linux operating system as an online server power source current sharing test automation script, and then invoking a stress pressurization tool built in the Linux to pressurize the CPU and an ipmitool command tool to perform reading and writing on power module hardware interaction, and performing current sharing test and outputting a result according to the test scheme program flowchart, wherein the specific implementation steps are as follows:
(1) Firstly, a tester copies a current sharing test script into a directory of a Linux operating system of a server, then starts an online current sharing test automation script (for example, "equivalent _ current _ test.sh") according to a mode of executing a Bash Shell script by a standard Linux operating system, and substitutes the script into a required setting parameter, wherein the script parameter setting and executing mode is as follows:
bash./equal_current_test.sh–p 5–r 10
where the parameters define-p = number of server power on and off, -r = number of output power readings.
(2) After the script runs, calling a built-in IPMI command tool ('ipmitool') in Linux according to a program of the power testing scheme according to the power testing scheme flow to perform interactive reading and writing on the power module. Respectively calling stress in the script codes to pressurize all CPUs to realize two conditions of 10% load and 20% load; (e.g., stress-110-cpu $ (cat/proc/cpu info | grep "processor" | wc-l)), and ipmitool commands perform server power on/off (e.g., ipmitool power on) and output power monitoring (e.g., ipmitool ddr | grep-ips).
(3) And automatically calculating and judging each sub-test result and process by an Error rate (% Error) calculation formula in real time in the test process, printing the sub-test result and process on a computer screen, and finally outputting a test summary 'Pass or Fail' and printing the test summary to the computer screen, wherein the specific test results are shown in tables 1 to 4.
And (3) an error rate calculation formula and test result judgment:
% Error (Error rate) =100% | PSUi-PSUaverage |/PSUaverage;
where i =1.. N (number of PSU), PSUi is actual PSU0, PSU1 \8230, output power reading, PSUaverage is output rated power, and furthermore the% Error rate needs to be less than 10% when the CPU is loaded at 10% load, and less than 5% if the CPU is loaded at 20% load, as examples:
for example, assuming that PSU0 and PSU1 are both 800W full (100%) rated power, and the load is 10% (10% output rated power is 800 × 10% = 80W), the error rates are calculated by ipmitool reading the actual readings of the power sensors as PSU0=83W and PSU1=90W, respectively as follows:
% Error0=100% (PSU 0-PSUaverage)/PSUaverage =100% ((83-80)/80) =3.7% (PSU 0 test result judged as pass)
% Error1=100% (PSU 1-PSUaverage)/PSUaverage =100% ((90-80)/80) =12.5% (PSU 1 test result judged no pass).
Referring to fig. 3, the steps of executing the online current sharing test automation script are as follows:
step one, a direct current power supply or an alternating current power supply supplies power, a server is started after the server is powered on, the number and the rated power of PSUs of a power supply module of the server are detected, the power supply module of the currently tested server is assumed to comprise 2 PSUs which are respectively marked as PSU0 and PSU1, and the rated power of the two PSUs is 80W;
step two, carrying out power-off and power-on by calling a power-on and power-off command of the ipmitool, repeating the power-on and power-off command five times at intervals of ten seconds, taking the situation at the moment as a scene 1, reading the power output power of the power supply by using the ipmitool (reading every 30 seconds, repeating the operation 10 times), and then calculating the error rate of the obtained data under the scene 1 to obtain the data shown in the following table 1;
TABLE 1 Scenario 1 actual output Power and error Rate
Step three, pressurizing the CPU to load to 10% of rated output power, taking the situation at this time as a scene 2, reading the power output power by using ipmitool (reading every 30s, repeating for 10 times), and then calculating the data in the following table 2 obtained by the error rate of the data obtained under the scene 1;
TABLE 2 Scenario 2 actual output Power and error Rate
Step four, unloading the load, namely pressurizing the CPU to 0%, pressurizing the CPU to 20% of rated output, taking the situation as a scene 3, reading the power output power by using ipmitool (reading every 30s, repeating for 10 times), and then calculating the data in the following table 3, wherein the error rate of the data obtained under the scene 3 is obtained;
TABLE 3 Scenario 3 actual output Power and error Rate
Step five, power-off and power-on are executed by means of an on-off command of ipmitool, the power-off and power-on are repeatedly executed five times at intervals of ten seconds, the situation at the time is taken as a scene 4, the ipmitool is used for reading power output power (the power output power is read once every 30s and is repeated 10 times), and then the data in the following table 4 is obtained by calculating the error rate of the data under the scene 3:
TABLE 4 Scenario 4 actual work output and error Rate
Step 6, determining a test result by combining the error rates under all the scenes; specifically, the error rate is respectively calculated according to the actual output power and the rated output power in the tables 1 to 4 to determine the test result, and the specific error rate calculation mode for each PSU is the ratio of the absolute value of the difference between the rated output power and the actual output power to the rated output power; for ease of understanding, the error rate may be set to 10% for scenario 1 and scenario 2 with a CPU load of 10%, that is, the error rate is determined to pass the test only if it is less than 10%, otherwise it is determined not to pass; accordingly, for scenario 3 and scenario 4 with a CPU load of 20%, the error rate may be set to a comparison value of 5%, that is, only if the error rate is less than 5%, the test is considered to pass, otherwise the test is considered not to pass; and the final test result needs to be combined with all the results of the scene 1, the scene 2, the scene 3 and the scene 4, and the error rate obtained by each calculation of each PSU in each scene is determined to be that the current sharing test of the whole power module passes only within a set range, otherwise, the test fails.
And 7, after the test is finished and the load of the CPU is unloaded, calling the power-on and power-off command of the ipmitool again to execute power-off so as to shut down the server.
It should be noted that the scenarios in the examples are only used for illustration, and specific setting parameters of the scenarios, such as load values, and comparison values of interval measurement times, power-up and power-down times, and setting of error rate in each scenario, etc., can be changed and adjusted, and the parameters in the above embodiments should not be construed as limiting the method of the present invention. In addition, the actual output powers listed in the above tables 1 to 4 are also only for illustration, and the specific values are subject to the actual read values.
The method adopts Bash Shell statements supported by a Linux operating system in a default mode and calls a stress pressurizing tool built in the Linux to pressurize the CPU, an ipmitool command tool built in the Linux is called to perform reading and writing on power module hardware interaction, CPU loading and output power monitoring, and current sharing tests of various pressure scenes, and the program can automatically judge whether a test result passes or does not pass through a current sharing algorithm.
