[0047] In order to solve the problems of the prior art, the present embodiment provides a performance evaluation method for a disk array, which can evaluate the performance of the disk array as a whole by analyzing the response time of a single disk processing IO operations, which is conducive to achieving efficient performance evaluation, and by analyzing each disk, the accuracy of the performance evaluation is improved. In specific application, the present embodiment first obtains the response time of each disk in the disk array processing IO operations, and based on the response time, determines the processing speed level corresponding to each disk, wherein the higher the processing speed level, the shorter the response time, and then obtains the weight information corresponding to the processing speed level of each disk, wherein the higher the processing speed level, the smaller the weight information. Finally, based on the average response time of each disk and the weight information, the performance information of the disk array is evaluated.

[0048] The performance evaluation method of the disk array of this embodiment can be applied to a terminal, which can be a computer, mobile phone, smart TV or other intelligent product terminal. Figure 1 As shown in , the performance evaluation method of the disk array of this embodiment includes the following steps:

[0049] Step S100: Obtain the response time of each disk in the disk array for processing IO operations, and determine the processing speed level corresponding to each disk based on the response time, wherein the higher the processing speed level, the shorter the response time.

[0050] In this embodiment, the disk array includes several disks, and the number of disks is set according to actual needs. Each disk can be of the same type or different types, for example, disk A is a mechanical hard drive and disk B is an SSD. To evaluate the overall performance of the disk array, this embodiment analyzes each disk in the disk array, analyzing the response time for each disk to process IO operations, and then determining the corresponding processing speed level for each disk. The processing speed level corresponds to the length of the response time for processing IO operations. The higher the processing speed level, the shorter the response time.

[0051] In one implementation, this embodiment includes the following steps when analyzing the processing speed level corresponding to each disk:

[0052] Step S101: Collect the number of IO operations processed by each disk within a preset time period, and the response time of each IO operation;

[0053] Step S102: Determine the average response time of each disk based on the number of times each disk processes IO operations and the response time of each processing of the IO operation;

[0054] Step S103: Determine the processing speed level corresponding to each disk based on the average response time.

[0055] Specifically, this embodiment first collects the number of times each disk processes IO operations within a preset time period, as well as the response time for each processing of the IO operation, for each disk, and records the response time for each processing of the IO operation. Next, the number of times each disk processes IO operations and the response time for each processing of the IO operation are used to calculate the total response time of each disk within the preset time period, and then the average response time of each disk is determined. The average response time can reflect the feedback sensitivity of each disk to IO operations. The shorter the average response time, the more sensitive the disk is to the feedback of IO operations, that is, the faster the disk processes IO operations. Based on this, this embodiment can determine the processing speed level corresponding to each disk according to the determined average response time of each disk.

[0056] In specific applications, this embodiment can pre-set a grading rule, which is set based on the disk type. Therefore, this embodiment first obtains the disk type corresponding to each disk in the disk array and obtains the grading rule corresponding to the disk type. The grading rule reflects the corresponding relationship between processing speed level and average response time. For example, the grading rule for a certain type of disk is: if the average response time is 5-10 seconds, the corresponding processing speed level is level 3, indicating a very fast processing speed for I / O operations; if the average response time is 10-15 seconds, the corresponding processing speed level is level 2, indicating a normal processing speed for I / O operations (i.e., meeting an average level or a preset standard level); and if the average response time is 15-20 seconds, the corresponding processing speed level is level 1, indicating a very slow processing speed for I / O operations. Next, this embodiment matches the average response time of each disk with the grading rule corresponding to that disk, thereby determining the processing speed level corresponding to each disk. By determining the processing speed level of each disk, this embodiment facilitates accurate analysis of the overall performance of the entire disk array in subsequent steps.

[0057] In another implementation, after obtaining the number of IO operations processed by each disk and the response time for each such IO operation, this embodiment can also obtain a preset first duration threshold and compare all response times corresponding to each disk with the first duration threshold. Then, for each disk, the percentage of all response times exceeding the first duration threshold is determined. This percentage reflects the ratio of the number of response times for each disk exceeding the first duration threshold to the total number of response times. This embodiment sets the first duration threshold to measure the response time of each disk, which facilitates analyzing whether the number of response times exceeding the first duration threshold or the number of response times less than the first duration threshold is higher for each disk. Furthermore, based on this percentage information, this embodiment can determine the processing speed grade corresponding to each disk. Specifically, this embodiment can also pre-set grade mapping information, which can also be set based on the disk type. This embodiment first obtains the disk type corresponding to each disk in the disk array and obtains grade mapping information corresponding to the disk type. This grade mapping information reflects the correspondence between the processing speed grade and the percentage information. For example, the level mapping information for a certain type of disk is as follows: if the proportion information is greater than 70% (i.e., the ratio of the number of times the response time in the disk exceeds the first time threshold to the total number is greater than 70%), then the corresponding processing speed level is level three, i.e., the processing speed for IO operations is very fast; if the proportion information is 50-70% (i.e., the ratio of the number of times the response time in the disk exceeds the first time threshold to the total number is 50-70%), then the corresponding processing speed level is level two, i.e., the processing speed for IO operations is normal (i.e., meets the ordinary level or the preset standard level); if the proportion information is less than 50% (i.e., the ratio of the number of times the response time in the disk exceeds the first time threshold to the total number is less than 50%), then the corresponding processing speed level is level one, i.e., the processing speed for IO operations is very slow. Based on the above-mentioned level mapping information, this embodiment matches the proportion information determined for each disk with the level mapping information corresponding to the disk, thereby determining the processing speed level corresponding to each disk.

[0058] Step S200: Obtain weight information corresponding to the processing speed level of each disk, wherein the higher the processing speed level, the smaller the weight information.

[0059] Since there are multiple disks in the disk array, and the processing speed level of each disk is different, that is, the average response time of each disk for processing IO operations is different, so the degree of influence of each disk on the overall performance of the disk array is also different. To this end, after obtaining the processing speed level of each disk, the weight information corresponding to the processing speed level of each disk is obtained respectively. The weight information can reflect the degree of influence of the processing speed level of each disk on the overall performance of the disk array. In one implementation, the weight information of this embodiment is pre-set, and the weight information corresponding to each processing speed level is different, and the higher the processing speed level, the smaller the corresponding weight information, and the lower the processing speed level, the larger the corresponding weight information. This means that when the processing speed level of a disk is lower, that is, the slower the processing speed for IO operations, the greater the impact on the overall performance of the disk array.

[0060] Step S300: Evaluate the performance information of the disk array based on the average response time of each disk and the weight information.

[0061] After determining the weight information of each disk, this embodiment can evaluate the performance information of the disk array based on the average response time of each disk and the weight information corresponding to the disk.

[0062] In one implementation, this embodiment includes the following steps when evaluating the performance information of a disk array:

[0063] Step S301: Calculate the overall response time of the disk array based on the average response time of each disk and the weight information;

[0064] Step S302: Evaluate the performance information of the disk array based on the overall response time.

[0065] Specifically, this embodiment calculates the overall response time of the disk array based on the average response time of each disk and the weight information. In practical applications, this embodiment can calculate the product of the response time and the corresponding weight information for each disk to obtain the first value of each disk. Then, the first values ​​of all disks are added together to obtain the second value of the disk array, and the second value is used as the overall response time of the disk array. After obtaining the overall response time, this embodiment can use a preset second time threshold and determine the time difference based on the overall response time and the preset second time threshold. Then, based on the time difference, determine the performance interval corresponding to the time difference, and use the response speed information reflected by the performance interval as the performance information of the disk array.

[0066] In one implementation, this embodiment pre-sets performance reference information for a disk array. This performance reference information includes a correspondence between numerical intervals corresponding to time differences and performance intervals. The performance intervals of this embodiment include an excellent performance interval, a normal performance interval, and an abnormal performance interval. Each performance interval reflects the disk array's response speed to IO operations. For example, the excellent performance interval reflects a fast response speed for IO operations; the normal performance interval reflects a normal response speed for IO operations (i.e., meeting an ordinary level or a preset standard level); and the abnormal performance interval reflects a slow response speed for IO operations. Therefore, after determining the time difference, this embodiment can determine the numerical interval corresponding to the time difference, and then match the numerical interval of the time difference with the performance reference information to determine the performance interval. The response speed information reflected in the performance interval is then used as the performance information of the disk array, thereby achieving an overall information evaluation of the disk array.

[0067] In other implementations, after evaluating the performance information of the disk array, this embodiment can analyze whether the disk array needs optimization and maintenance based on the disk array performance information. Furthermore, when optimization or maintenance is required, this embodiment can further locate abnormal disks in the disk array and perform targeted optimization on them, thereby ensuring that the disk array meets usage requirements and extending the service life of the disk array.

[0068] In summary, this embodiment can first obtain the response time of each disk in the disk array for processing IO operations, and based on the response time, determine the processing speed level corresponding to each disk, wherein the higher the processing speed level, the shorter the response time. Then, obtain the weight information corresponding to the processing speed level of each disk, wherein the higher the processing speed level, the smaller the weight information. Finally, based on the average response time of each disk and the weight information, evaluate the performance information of the disk array. This embodiment can perform an overall evaluation of the performance of the disk array by analyzing the response time of a single disk processing IO operations, which is conducive to achieving efficient performance evaluation, and by analyzing each disk, the accuracy of the performance evaluation is improved.
