Data writing and reading are performed by continuously charging and discharging, and it has a variety of application scenarios. When testing the disk, it is necessary to pay attention to performance testing tools under the Linux system. Currently, mainly open-source IO tools such as FIO and vdbench are used for testing.

However, such test requirements are relatively special. For example, in the test of writing the entire SSD disk multiple times, it is not easy to view or distinguish the performance results of the disk's several times of writing when viewing the entire result, which will cause certain troubles in analyzing the reasons for performance problems.

[0026] SSD (Solid State Disk or Solid State Drive, hereinafter referred to as SSD), also known as a solid-state hard drive or solid-state drive, is a hard drive made of solid-state electronic storage chip arrays. Its read speed can reach several times that of a mechanical hard drive. Data writing and reading are performed by continuously charging and discharging, and it has a variety of application scenarios. When testing the disk, it is necessary to pay attention to the performance testing tools under the Linux system. Currently, mainly open-source IO tools such as FIO and vdbench are used for testing. These two testing tools complete the corresponding tests through the configuration of relevant parameters, and process and analyze the test results according to the work requirements, analyze how the disk performs under the corresponding tests, and find the reasons for abnormalities. Now, there are mainly several methods for analyzing whether the performance of a large number of disks is consistent and stable:

[0027] 1) By configuring parameters on different hosts, performing corresponding tests on the disks, and then viewing and analyzing the data that needs to be concerned in the results after completion.

[0028] 2) Based on the development platform of the performance testing tool, connect the device and then perform the performance tool test, and analyze the results after completion.

[0029] 2. Objective drawbacks of the related technologies:

[0030] At present, the Linux performance test is tested by FIO and vdbench performance tools. The performance test output results can record the corresponding performance of each second, such as bandwidth, IOPS, and latency. Therefore, there are corresponding drawing tools that can extract the data of each second and draw the results into images for viewing. However, in actual testing, there are often a large number of businesses that need to pay attention to the performance data of multiple capacities for a long time, and the performance of the disk when reading or writing repeatedly, that is, the performance when reading or writing multiple capacities (at least twice), so as to find out whether the disk has performance fluctuations when the state changes, and analyze the reasons. This kind of test requirements are relatively special. For example, when the entire SSD disk is written multiple times, it is not easy to view or distinguish the performance results of the disk when viewing the entire result, which will cause some trouble in analyzing the causes of performance problems. Therefore, the performance result data needs to be further processed. At the same time, if abnormal speed reduction or fluctuation occurs during the performance test, a large amount of SSD log information needs to be manually confirmed, and the cause of the problem needs to be analyzed by time point. Therefore, the entire test result processing and analysis process is cumbersome, and a large amount of data analysis and processing needs to be performed manually, which requires testers to have high efficiency and more experience.

[0031] Based on this, a performance test method, device and storage medium of a solid-state hard disk provided by an embodiment of the present invention can obtain a plurality of predetermined solid-state hard disks to be tested and a plurality of test machines, each test machine is equipped with a corresponding performance test tool, determine the test order of the solid-state hard disk to be tested, the target performance test tool in the performance test tool and the execution order of the target performance test tool based on the pre-set test rules, and repeatedly read or write the solid-state hard disk to be tested based on the test order and the execution order. During the test, read the target performance test tool data recorded by the test machine, and perform fluctuation anomaly detection based on the target performance test tool data to obtain the test result, adjust the target performance test tool and the corresponding execution order based on the test result, continue to test after adjustment, and obtain the test result, which includes the test result, and perform data processing based on the test result and one-time capacity of the solid-state hard disk to visualize the test result based on multiple times of capacity. In this way, the convenience of analyzing the cause of performance problems is improved, the cumbersomeness of the processing flow is reduced, and the labor cost is reduced.

[0032] To facilitate understanding of this embodiment, a performance testing method for a solid state drive disclosed in an embodiment of the present invention is first introduced in detail.

[0033] Example 1

[0034] The embodiment of the present invention provides a method for testing the performance of a solid state drive. Figure 1 The present invention provides a flow chart of a method for testing the performance of a solid state drive. Figure 1As shown, the performance testing method for the solid-state drive may include the following steps:

[0035] Step S101: Obtain a plurality of pre-determined solid-state drives to be tested and a plurality of test machines.

[0036] Among them, each test machine is installed with a corresponding performance testing tool.

[0037] Before the test, test environment preparation is required. Therefore, before obtaining a plurality of pre-determined solid-state drives to be tested and a plurality of test machines, the method may further include: determining the number of solid-state drives to be tested and the number of test machines based on the actual work; installing a corresponding performance testing tool on each test machine for the control host to control the corresponding test machine to start the test program through the network and the developed system; where the versions of the performance testing tools are the same; during the test, each test machine tests one solid-state drive to be tested at a time, and tests the next solid-state drive to be tested after the test is completed.

[0038] Among them, before the test, it is necessary to ensure that the performance testing tools FIO, vdbench and their versions installed on each test machine are the same. At the same time, ensure that each test machine and the serial port host are connected to the network, and the network IP (Internet Protocol) of each host is also different. The test system is at the control host. Through the IP of the test host, the control host can connect to the test machine through SSH (Secure Shell) and the IP. Subsequently, the system program can control each test machine and the serial port host, perform corresponding steps on the test machine, generate a test tool parameter file, and start the test tools: FIO, vdbench, to test the solid-state drive. At the same time, it is necessary to ensure that the identification codes of each solid-state drive are inconsistent (generally identified by the SN: Serial Number of the solid-state drive during the test).

[0039] Among them, install the serial port tool Teraterm on the serial port host, connect each SSD on the test machine through the serial cable, select the "Serial" option in the top menu bar of the tool, then select the correct COM port and baud rate, and click "OK". In the newly opened terminal window, a prompt can be seen, indicating that the connection to the SSD has been established, and the print logs of each SSD serial port can be displayed. At the same time, save the print logs of the connected SSD serial ports in a certain format and path.

[0040] Step S102: Determine the test order of the solid-state drives to be tested, the target performance testing tool in the performance testing tool, and the execution order of the target performance testing tool based on the pre-set test rules.

[0041] Among them, the test rules may include the performance to be tested for the solid-state drive to be tested and the corresponding performance test tool for this performance, as well as the test order of multiple solid-state drives to be tested and the execution order of the performance test tool.

[0042] Specifically, the relevant interface of the control host test system (which can be implemented through programming languages) can select the tools to be tested and the execution order. Then, the system executes the code of the test system according to the configured order, and controls the test host to perform tests according to the specified test tools. Some necessary test parameters need to be configured on the system interface of the control host: the test object, whether to select FIO or vdbench for testing. After selection, the corresponding parameters need to be configured, such as the IO size, read / write mode, read / write data volume (at least twice the capacity), and the result data to be saved.

[0043] Step S103: Perform repeated read or write tests on the solid-state drive to be tested based on the test order and execution order.

[0044] Among them, through relevant settings on the control host, the control host will run a program to generate corresponding parameter configuration files on each test machine, control the order of the corresponding test solid-state drives on each test host, and start the test. Due to the particularity of performance testing, in order to ensure the accuracy of the test and optimal data, each test machine only tests the performance of one solid-state drive each time during the test. After the test is completed, the test of the next solid-state drive is carried out.

[0045] Step S104: During the test, read the data of the target performance test tool recorded by the test machine, and perform fluctuation anomaly detection based on the data of the target performance test tool to obtain the detection result.

[0046] Among them, the control host can read the solid-state drive being tested on each test machine and the corresponding performance tool test data, and refresh it at a certain time interval. This interval time can be selected on the system, such as one hour. At the same time, the system identifies the points in the data with significantly higher volatility than the normal level according to the designed performance fluctuation anomaly detection algorithm. This point is the abnormal fluctuation data point.

[0047] Step S105: Adjust the target performance test tool and the corresponding execution order based on the detection result, and continue the test after adjustment to obtain the test result.

[0048] Among them, the test result includes the detection result.

[0049] Specifically, adjusting the target performance test tool and the corresponding execution order based on the detection result may include: determining whether there are abnormal fluctuation data points based on the detection result; if there are no abnormal fluctuation data points, adjusting the target performance test tool to the performance test tool corresponding to the untested performance.

[0050] Among them, the purpose of performance testing is to identify unstable performance. Therefore, during the testing process, if a function does not exhibit abnormalities within a preset time interval, excessive testing of this performance is not carried out. In subsequent tests, it is replaced with untested performance, and performance testing is performed through the performance testing tool corresponding to this performance.

[0051] Among them, the preset time interval is determined according to the actual situation, such as the sequence of time when some performances exhibit abnormalities during daily use, etc.

[0052] Step S106, perform data processing based on the test results and one - fold capacity of the solid - state drive to perform visual display of the test results based on multiple - fold capacity.

[0053] Among them, after the test is completed, the test results can be saved at the specified location of the test machine according to the specified name in the parameter configuration. Multiple solid - state drives and various test results are distinguished by naming. First, select the file results to be processed according to the path in the relevant interface of the test system of the control - end host: bandwidth results, iops results, latency results, etc.

[0054] Among them, the test results include the data volume generated during the testing process, such as the written data volume or the read data volume. This data volume is usually generated after the solid - state drive is repeatedly overwritten (corresponding to the multiple - fold capacity of the solid - state drive). Therefore, when analyzing the data volume corresponding to each fold capacity of the solid - state drive, the data volume corresponding to multiple - fold capacity is relatively cumbersome. Thus, the data can be divided by one - fold capacity, and then visual display of multiple - fold capacity can be performed through the divided data volume.

[0055] The performance testing method for a solid - state drive provided by the embodiments of the present invention can obtain a plurality of predetermined solid - state drives to be tested and a plurality of test machines. Each test machine is installed with a corresponding performance testing tool. Based on the pre - set test rules, determine the test order of the solid - state drives to be tested, the target performance testing tool in the performance testing tool, and the execution order of the target performance testing tool. Perform repeated read or write tests on the solid - state drives to be tested based on the test order and the execution order. During the testing process, read the data of the target performance testing tool recorded by the test machine, and perform fluctuation abnormality detection based on the data of the target performance testing tool to obtain the detection result. Adjust the target performance testing tool and the corresponding execution order based on the detection result, and continue the testing after adjustment to obtain the test result. The test result includes the detection result. Perform data processing based on the test result and one - fold capacity of the solid - state drive to perform visual display of the test result based on multiple - fold capacity. In this way, the convenience of analyzing the cause of performance problems is improved, the complexity of the processing process is reduced, and the labor cost is reduced.

[0056] Embodiment 2

[0057] The embodiment of the present invention also provides another method for testing the performance of a solid-state drive; this method is implemented on the basis of the method in the above embodiment; this method focuses on describing the specific implementation manner of detecting abnormal fluctuations based on the data of the target performance testing tool to obtain the detection result.

[0058] Figure 2 It is a flowchart of another method for testing the performance of a solid-state drive provided by the embodiment of the present invention. As Figure 2 shown, the process of detecting abnormal fluctuations based on the data of the target performance testing tool to obtain the detection result may include the following steps:

[0059] Step S201, determine whether there are abnormally fluctuating data points based on the data of the target performance testing tool to obtain a determination result.

[0060] Specifically, determining whether there are abnormally fluctuating data points based on the data of the target performance testing tool to obtain a determination result may include: determining the moving average value and the moving standard deviation of the data of the target performance testing tool; comparing the moving average value and the moving standard deviation with a pre-set first abnormal threshold and a second abnormal threshold respectively; if the moving average value is greater than the first abnormal threshold and the moving standard deviation is greater than the second abnormal threshold, it is determined that there are abnormally fluctuating data points.

[0061] Step S202, if it is determined based on the determination result that there are abnormally fluctuating data points, extract the serial port log corresponding to the abnormally fluctuating data points.

[0062] Specifically, extracting the serial port log corresponding to the abnormally fluctuating data points may include: determining the time point corresponding to the abnormally fluctuating data points; extracting the corresponding serial port log based on the time point.

[0063] Step S203, determine the reason for the abnormal fluctuation of the abnormally fluctuating data points based on the serial port log.

[0064] Specifically, determining the reason for the abnormal fluctuation of the abnormally fluctuating data points based on the serial port log may include: determining the first quantity of the target prints within a preset time before and after the time point based on the serial port log; the target prints are ecc high prints or read retry prints; if the first quantity exceeds the pre-set first quantity threshold, the reason for the abnormal fluctuation is the occurrence of the first quantity of target prints; determining whether riskGC prints appear at the time point based on the serial port log; if riskGC prints appear, the reason for the abnormal fluctuation is the appearance of riskGC prints in the serial port log; determining whether V appears at the time point based on the serial port log; if V appears, the reason for the abnormal fluctuation is the occurrence of read disturb.

[0065] Among them, ecc high indicates that the number of bit flips is higher than the threshold, read retry indicates re-reading, risk GC indicates garbage collection, V indicates the process of applying corresponding virtual blocks during the writing process of the solid-state drive, and read disturb indicates read interference.

[0066] Among them, after determining the cause of the abnormal fluctuation of the abnormal fluctuation data point, the cause of the abnormal fluctuation can be marked corresponding to the abnormal fluctuation data point, so that when the subsequent visual display is performed, the cause of the abnormal fluctuation of the abnormal fluctuation data point can be displayed.

[0067] Step S204, when it is determined that the result representation has abnormal fluctuation data points, the abnormal fluctuation data points and the corresponding causes of the abnormal fluctuations of the abnormal fluctuation data points are used as the detection results.

[0068] Step S205, when it is determined that the result representation does not have abnormal fluctuation data points, the fact that the target performance test tool data does not have abnormal fluctuation data points is used as the detection result.

[0069] The performance test method of the solid-state drive provided by the embodiment of the present invention can, by detecting abnormal fluctuations during the test process, process a large amount of data in advance to share the data processing pressure after the test is completed, and through the detection of the abnormal fluctuations, provide a basis for the subsequent adjustment of the target performance test tool, so as to reduce the consumption of the computing power resources of the system.

[0070] Embodiment 3

[0071] The embodiment of the present invention also provides another performance test method for a solid-state drive; this method is implemented on the basis of the method of the above embodiment; this method focuses on describing the specific implementation manner of performing data processing based on the test result and the single capacity of the solid-state drive to perform visual display of the test result based on multiple capacities.

[0072] Figure 3 is a flowchart of another performance test method for a solid-state drive provided by the embodiment of the present invention, as Figure 3 shown, this performing data processing based on the test result and the single capacity of the solid-state drive to perform visual display of the test result based on multiple capacities may include the following steps:

[0073] Step S301, determining the data volume per second based on the test result.

[0074] Among them, the data volume is: the written data volume or the read data volume.

[0075] Step S302, determining the time length corresponding to the data volume of writing to or reading from the single capacity of the solid-state drive.

[0076] Among them, the capacity of one times the solid-state drive can be determined, and this one-time capacity can be divided from all the data volumes corresponding to the test results. Then, the start and end times of the divided capacity during writing or reading are determined, so that the corresponding time length can be determined through the start time.

[0077] Among them, the test result corresponds to the test result of a certain performance. Therefore, all the data volumes are related to the tested performance, and the subsequent visual display also corresponds to this performance.

[0078] Step S303: Split all the data volumes in the test results based on the time length.

[0079] Among them, all the data volumes can be split by the above-mentioned splitting method.

[0080] Step S304: Display the data points corresponding to the data volume of each one-time capacity obtained by splitting in a line chart to view the performance changes of the solid-state drive under multiple capacities.

[0081] Among them, each one-time capacity can be separately displayed by different colors or lines with different forms.

[0082] The performance test method of the solid-state drive provided by the embodiment of the present invention can display the data anomalies corresponding to each one-time capacity in a comparative manner through visual display based on multiple capacities, and display the corresponding anomaly reasons at the anomaly positions, improving the convenience of analyzing the test results.
