[0022] In order to solve the problems of the prior art, this embodiment provides a performance evaluation method for a disk array, which can evaluate the performance of the disk array as a whole by 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, this embodiment first obtains the response time of each disk in the disk array to process 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.

[0023] The disk array performance evaluation method of this embodiment can be applied to a terminal, which can be a computer, a mobile phone, a 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: Step S100, obtaining the response time of each disk in the disk array for processing IO operations, and determining 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.

[0024] In this embodiment, the disk array includes several disks, and the number of disks is set according to actual needs. Each disk can be a disk of the same type or a disk of a different type, such as disk A is a mechanical hard disk and disk B is an SSD. In order to evaluate the overall performance of the disk array, this embodiment can analyze each disk in the disk array, analyze the response time of each disk processing IO operations respectively, and then determine the processing speed level corresponding to 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.

[0025] In one implementation, when analyzing the processing speed level corresponding to each disk, this embodiment includes the following steps: Step S101, collecting the number of IO operations processed by each disk within a preset time period, and the response time of each processing of the IO operation; Step S102: determining an 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; Step S103: Determine the processing speed level corresponding to each disk based on the average response time.

[0026] 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 of each processing of the IO operation, for each disk, and records the response time of each processing of the IO operation. Then, the number of times each disk processes IO operations and the response time of 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.

[0027] In specific applications, this embodiment can pre-set a grade division rule, which is set according to the type of disk. Therefore, this embodiment first obtains the disk type corresponding to each disk in the disk array, and obtains the grade division rule corresponding to the disk type, wherein the grade division rule reflects the corresponding relationship between the processing speed level and the average response time. For example, the grade division rule for a certain type of disk is: if the average response time is 5-10s, the corresponding processing speed level is level three, that is, the processing speed for IO operations is very fast; if the average response time is 10-15s, the corresponding processing speed level is level two, that is, the processing speed for IO operations is normal (that is, it meets the ordinary level or the preset standard level); if the average response time is 15-20s, the corresponding processing speed level is level one, that is, the processing speed for IO operations is very slow. Next, this embodiment matches the average response time of each disk with the grade division rule corresponding to the disk, thereby determining the processing speed level corresponding to each disk. This embodiment is conducive to accurately analyzing the overall performance of the entire disk array in subsequent steps by determining the processing speed level of each disk.

[0028] In another implementation, after obtaining the number of times each disk processes IO operations and the response time of each processing of the IO operation, the present embodiment can also obtain a preset first time threshold, and compare all response times corresponding to each disk with the first time threshold. Then, for each disk, determine the proportion information of all response times greater than the first time threshold, and the proportion information reflects the ratio between the number of times the response time of each disk is greater than the first time threshold and the total number of times. The present embodiment sets the first time threshold to measure the response time of each disk, which is conducive to analyzing whether the number of response times greater than the first time threshold is greater or the number of response times less than the first time threshold is greater in each disk. Further, based on the proportion information, the present embodiment can determine the processing speed level corresponding to each disk. Specifically, the present embodiment can also pre-set the level mapping information, and the level mapping information can also be set according to the type of the disk. The present embodiment first obtains the disk type corresponding to each disk in the disk array, and obtains the level mapping information corresponding to the disk type, wherein the level mapping information reflects the corresponding relationship between the processing speed level and the proportion information. For example, the level mapping information for a certain type of disk is: if the proportion information is greater than 70% (i.e., the ratio between the number of times the response time in the disk is greater than the first time threshold and the total number is greater than 70%), the corresponding processing speed level is level three, that is, the processing speed for IO operations is very fast; if the proportion information is 50-70% (i.e., the ratio between the number of times the response time in the disk is greater than the first time threshold and the total number is 50-70%), the corresponding processing speed level is level two, that is, the processing speed for IO operations is normal (i.e., it meets the ordinary level or the preset standard level); if the proportion information is less than 50% (i.e., the ratio between the number of times the response time in the disk is greater than the first time threshold and the total number is less than 50%), the corresponding processing speed level is level one, that is, the processing speed for IO operations is very slow. Based on the above-mentioned level mapping information, this embodiment will match the proportion information determined for each disk with the level mapping information corresponding to the disk, so as to determine the processing speed level corresponding to each disk.

[0029] 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.

[0030] 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, and 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, which means that when the processing speed level of a certain disk is lower, that is, the slower the processing speed of IO operations, the greater the impact on the overall performance of the disk array.

[0031] Step S300: Evaluate the performance information of the disk array based on the average response time of each disk and the weight information.

[0032] After the weight information of each disk is determined, 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.

[0033] In one implementation, this embodiment includes the following steps when evaluating the performance information of the disk array: Step S301, calculating the overall response time of the disk array based on the average response time of each disk and the weight information; Step S302: Evaluate the performance information of the disk array based on the overall response time.

[0034] 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 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.

[0035] In one implementation, the present embodiment pre-sets the performance reference information of the disk array, and the performance reference information is provided with a corresponding relationship between the numerical interval corresponding to the time difference and the performance interval. The performance interval of the present embodiment includes an excellent performance interval, a normal performance interval, and an abnormal performance interval. Each performance interval reflects the response speed information of the disk array to the IO operation. For example, the excellent performance interval reflects that the disk array has a fast response speed to the IO operation; the normal performance interval reflects that the disk array has a normal response speed to the IO operation (i.e., it meets the ordinary level or the preset standard level); the abnormal performance interval reflects that the disk array has a slow response speed to the IO operation. Therefore, after determining the time difference, the present 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, and then use the response speed information reflected by the performance interval as the performance information of the disk array, thereby realizing the evaluation of the overall information of the disk array.

[0036] In other implementations, after evaluating the performance information of the disk array, this embodiment can analyze whether the disk array needs to be optimized and maintained based on the performance information of the disk array. Moreover, when the disk array needs to be optimized or maintained, this embodiment can further locate the abnormal disk in the disk array and perform targeted optimization on the abnormal disk, so that the disk array can meet the use requirements and extend the service life of the disk array.

[0037] In summary, this embodiment can first obtain the response time of each disk in the disk array to process 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 to process IO operations, which is conducive to achieving efficient performance evaluation, and by analyzing each disk, the accuracy of the performance evaluation is improved.
