In a Non-Uniform Memory Access (NUMA) architecture, different Memory devices and a Central Processing Unit (CPU) core belong to different processor nodes (nodes), and each Node has its own Integrated Memory Controller (IMC); for example, if a server has 2 processors and 4 solid state drives, 1 processor and two solid state drives can be combined to form a processor Node (NUMA Node), and thus the server includes two processor nodes.
Optionally, one hard disk corresponds to one processor node, one processor node corresponds to one or more hard disks, at least one hard disk to be tested is provided, and if a plurality of hard disks to be tested are provided, the hard disks to be tested may belong to the same processor node or may not belong to the same processor node.
The configuration parameters comprise the hard disk to be tested and the corresponding processor node, so that the configuration parameters can be directly analyzed to obtain the processor node to which the hard disk to be tested belongs.

After a target processor core of a hard disk to be tested is obtained, the hard disk to be tested is bound with the target processor core, then the hard disk to be tested is tested through the target processor core to obtain a performance test result of the hard disk to be tested, and the performance test result is collected into a specified file, wherein the file format can be a Comma-Separated Values (CSV) file or other file formats capable of clearly representing the performance test result.
Optionally, if the hard disk to be tested is a plurality of test hard disks, the performance test results of the plurality of test hard disks can be obtained, including a single test result file of each test hard disk or a test result file summarized by the plurality of test hard disks.
It should be noted that, the configuration parameters carried in the test instruction may further include: bandwidth (bw), queue depth (iododepth), runtime and thread number (numjobs) of a hard disk to be tested, wherein the queue depth represents Input/Output (I/O) queue depth; runtime is specified time, which indicates that when the time for completing reading and writing the data in the hard disk is less than the specified time, the test tool is finished when the reading and writing of all the data in the hard disk are completed; but when the time needed for reading and writing the data in the hard disk is longer than the designated time, the test tool is finished after running the designated time.
The performance test parameters include Input/Output Per Second (IOPS), bandwidth (BW), latency (lat), cpu _ usr, and cpusys, where IOPS is one of the main indicators for measuring disk performance, and represents the number of I/O requests that can be processed by the system in a unit time, and generally takes the number of I/O requests processed Per Second as a unit, and the I/O requests are usually read or write data operation requests; BW refers to the amount of data that can be transmitted in a fixed time, i.e., the capacity of data to be transmitted in the transmission pipeline; the delay includes an IO commit delay (slat) and an IO completion delay (clat); the CPU _ usr represents the utilization rate of the user-mode CPU, namely the percentage of the user space occupying the CPU; cpsys represents the percentage of CPU occupied by kernel space.
Based on this, the obtained performance test result includes the corresponding performance test parameters under the pre-configured parameters, so the performance test result can be displayed in the format of the table file.
According to the hard disk performance testing method, the server responds to a testing instruction of the hard disk to be tested, determines a processor node to which the hard disk to be tested belongs according to configuration parameters carried in the testing instruction, determines target processor cores of the hard disk to be tested from all processor cores in the processor node, and then tests the hard disk to be tested through the target processor cores to obtain a performance testing result of the hard disk to be tested. According to the method, the target processor core corresponding to the hard disk to be tested is determined in the processor node to which the hard disk to be tested belongs, the performance of the hard disk to be tested is tested through the target processor core, the hard disk to be tested is tested through the corresponding processor core, and the performance test result can better represent the performance of the hard disk on the server and improve the accuracy of the performance test of the hard disk on the server because the target processor core for testing the hard disk to be tested is the core in the processor node to which the hard disk to be tested belongs.
In one embodiment, the configuration parameters include identification information of the hard disk to be tested; determining a processor node to which a hard disk to be tested belongs according to configuration parameters carried in a test instruction, wherein the method comprises the following steps: and determining the processor node to which the hard disk to be tested belongs according to the identification information of the hard disk to be tested and the corresponding relation between the preset hard disk and the processor node.
The server stores the corresponding relation between the hard disk and the processor nodes, namely, the identification information of the hard disk corresponds to the identification of the processor nodes one by one, so that the processor nodes of the hard disk to be tested are determined according to the identification information of the hard disk to be tested in the configuration parameters.
Optionally, the processor node to which the hard disk to be tested belongs may be searched for according to the lspci command and the corresponding relationship between the preset hard disk and the processor node and the identification information of the hard disk to be tested.
The identification information of the hard disk to be tested can be number information and can uniquely identify the hard disk to be tested; therefore, the processor node to which the hard disk belongs can be searched through the number information of the hard disk to be tested.
The server pre-stores the corresponding relation between the processor nodes and the processor cores, so that all the processor cores can be obtained from the processor nodes to which the hard disk to be tested belongs based on the obtained processor nodes to which the hard disk to be tested belongs; specifically, all processor cores under the processor node to which the kernel-H command belongs can be found out, where the kernel tool can be used to view information such as configuration and state of the processor node of the current server.
In this embodiment, the processor node to which the hard disk to be tested belongs can be determined more quickly through the preset corresponding relationship between the hard disk and the processor node, so that it is convenient to determine the target processor core of the hard disk to be tested from the processing node to which the hard disk belongs subsequently
How to determine the target processor core of the hard disk to be tested from all the processor cores in the processor node to which the hard disk to be tested belongs is described below through an embodiment, in which, as shown in fig. 3, determining the target processor core of the hard disk to be tested from all the processor cores in the processor node includes the following steps:
s301, acquiring priority information of all processor cores in the processor node to which the hard disk to be tested belongs.
And acquiring priority information of all processor cores according to all processor cores in the processor node to which the hard disk to be tested belongs, wherein the priority information can represent the priority of the response sequence of all processor cores in the processor node.
The priority of the processor core may be determined according to the occupation state of the processor core, or may be determined according to parameter information of the processor core, for example, the parameter information may be parameters such as the cache size of each level, the core voltage, and the power consumption.
Optionally, the server allocates a core number to the processor core in each processor node, and the priority information of the processor core may also be determined according to the core number, for example, the smaller the number, the higher the priority.
It should be noted that, in the embodiment of the present application, a determination manner of priority information of all processor cores in a processor node to which a hard disk to be tested belongs is not limited.
S302, according to the mapping relation between the preset hard disk and the number of the processor cores and the priority of each processor core, determining the target processor core of the hard disk to be tested in all the processor cores in the processor node.
The server prestores mapping relationships between the hard disks and the number of the processor cores, and optionally, each hard disk corresponds to one number of the processor cores, and the number of the processor cores corresponding to each hard disk may be the same or different.
Therefore, in an embodiment, as shown in fig. 4, determining a target processor core of a hard disk to be tested in all processor cores in a processor node according to the priority of each processor core according to a mapping relationship between a preset hard disk and the number of processor cores includes the following steps:
s401, determining the required number of the target processor cores according to the mapping relation between the preset hard disk and the number of the processor cores.
The required number of the target processor cores corresponding to the hard disk to be tested is determined according to the mapping relation between the preset hard disk and the number of the processor cores, specifically, the number of the processor cores corresponding to the hard disk to be tested can be searched in the mapping relation between the preset hard disk and the number of the processor cores according to the identification information of the hard disk to be tested, and the number is the required number of the target processor cores corresponding to the hard disk to be tested.
For example, if the identifier of the hard disk to be tested is a, the number of processor cores corresponding to a is found to be 5 in the mapping relationship between the hard disk and the number of processor cores, and then the number of target processor cores required by the hard disk to be tested is 5.

For example, if 5 processor cores are needed by the hard disk to be tested, according to the sequence from high priority to low priority, 5 processor cores are sequentially obtained from all the processor cores in the processor node to which the hard disk to be tested belongs, and the 5 processor cores are the target processor cores of the hard disk to be tested.
If the hard disks to be tested are a plurality of hard disks and the hard disks are under the same processor node, acquiring the processor cores with the required number corresponding to the hard disks in sequence from high priority to low priority; optionally, if all the processor cores under the processor node are occupied, the processor cores under the processor node are acquired again according to the sequence from high priority to low priority.

The method determines a target processor core of the hard disk to be tested according to priority information of all processor cores in a processor node to which the hard disk to be tested belongs, ensures that the target processor core corresponding to the hard disk to be tested is obtained from the processor node to which the hard disk to be tested belongs, and utilizes the processor core in the processor node to perform performance test on the hard disk to be tested, thereby ensuring the accuracy of a performance test result; and the target processor core of the hard disk to be tested can be quickly and accurately determined in all the processor cores in the processor node based on the priority information and the mapping relation of all the processor cores in the processor node.
Based on the obtained target processor core corresponding to the hard disk to be tested, how to test the hard disk to be tested through the target processor core is described below through an embodiment, in an embodiment, as shown in fig. 5, the method for testing the hard disk to be tested through the target processor core to obtain a performance test result of the hard disk to be tested includes the following steps:
