SSD storage devices have become mainstream storage devices.

[0003] As we all know, once an SSD storage device is damaged, it is easy to cause data loss, and even bring huge losses and unforeseen consequences. Therefore, estimating the remaining life of SSDs has become the core research direction of researchers. At present, the common SSD remaining life estimation method is mainly based on the SMART information provided by SSD chip manufacturers, including wear, operating temperature, number of bad blocks, etc., and linear calculation is performed to estimate the remaining life based on the wear.

[0069] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0070] With the advent of the Internet era, traditional hard disk drive (HDD) storage devices are gradually unable to meet the massive input / output (IO) requirements. Solid State Drive (SSD) has gained wide favor with its superior IO performance. Domestic and foreign large data centers such as Baidu Cloud, Tencent Cloud and Google Cloud have fully adopted SSD storage devices as the basic storage unit when building storage systems. SSD storage devices have become the mainstream storage devices.

[0071] As we all know, once an SSD storage device is damaged, it is difficult to repair and it is easy to cause data loss, and even bring huge losses and unforeseen consequences. Therefore, estimating the remaining life of SSDs has become the core research direction of researchers.

[0072] Currently, common methods for estimating the remaining life of an SSD include:

[0073] 1) Determine the remaining life of the disk based on the SMART information provided by the SSD chip manufacturer (including manufacturer information, wear level, operating temperature, number of bad blocks, etc.). However, due to differences in real-time load, usage scenarios, and SSD storage device processes, the service life estimated by traditional SMART information is inaccurate.

[0074] 2) The time series-based neural network prediction model and the traditional wear-based prediction model are used to estimate the remaining life of the disk, including: linear calculation based on SMART information, and estimating an approximate remaining life value based on the wear value. This method is relatively simple, and the prediction results often change linearly with the write volume and wear, and have low accuracy and reliability.

[0075] 3) Refine the SMART information sampling rate, and construct samples based on sampling timestamps and wear, select different algorithms for processing different dates, select neural network models and linear mappings to construct piecewise functions, and use the divide-and-conquer idea to deal with SSD storage device life estimation in different scenarios. This method combines deep neural networks and traditional linear calculations to estimate the life of SSD storage devices, and has good estimation performance. However, training a good neural network model often requires a large number of training samples, and it is difficult to achieve such large-scale wear sampling and labeling in practical applications.

[0076] 4) Based on the traditional wear prediction model and weighted average algorithm, the remaining life of the SSD is predicted. This method refines the granularity of wear, for example, the number of days used for 1% wear is used as a parameter and sorted by time, and the parameter with a time closer to the current prediction period is given a larger weight. The final weighted summation result can be used to calculate the remaining life of the SSD storage device, or a weighted summation is performed based on different characteristic factors, and different characteristic factors are assigned different weights for calculation. This type of method has the ability to dynamically predict the remaining life of the SSD, but the determination of the weight coefficient needs to be set based on experience, which is difficult to debug.

[0077] In summary, the above-mentioned method for estimating the remaining life of an SSD has the problem of inaccurate estimation. This application aims to solve this problem.

[0078] After introducing the background technology of the hard disk life estimation method provided in the embodiment of the present application, the implementation environment involved in the hard disk life estimation method provided in the embodiment of the present application will be briefly described below. The hard disk life estimation method provided in the embodiment of the present application can be applied in the implementation environment as shown in Figure 1. The implementation environment includes a server 104, which can be implemented as an independent server 104 or a server cluster composed of multiple servers 104, and a data storage system 102 can store data that the server 104 needs to process. The data storage system 102 can be integrated on the server 104, or it can be placed on the cloud or other network servers. Among them, the data storage system 102 can collect and pre-store the operating parameters of the target hard disk in each cycle, as well as the operating parameters of all hard disks in the storage pool in the first cycle. The server 104 can obtain the operating parameters of the target hard disk in each cycle, as well as the operating parameters of all hard disks in the storage pool in the first cycle from the data storage system 102, and determine the life consumption of the target hard disk within a preset time period based on the operating parameters of the target hard disk in each cycle, as well as the operating parameters of all hard disks in the storage pool in the first cycle, and estimate the remaining life of the target hard disk based on the wear parameters and life consumption of the target hard disk.

[0079] In other possible implementations, the hard disk life estimation method provided in the embodiment of the present application can also be applied to terminals, which can be, but are not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart car devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc.

[0080] After introducing the application scenarios of the hard disk life estimation method provided in the embodiments of the present application, the following focuses on introducing the hard disk life estimation method described in the present application.

[0081] In one embodiment, Figure 2 As shown, a method for estimating the life of a hard disk is provided, and the method is applied to the server in FIG1 as an example for explanation, including the following steps:

[0082] S201, obtaining first operating parameters of a target hard disk within a preset number of cycles, and second operating parameters of all hard disks in a storage pool within a target cycle.

[0083] The preset number of cycles refers to the cycle of obtaining the operating parameters of the hard disk when estimating the remaining life of the hard disk. In the embodiment of the present application, the preset number of cycles includes the first cycle, the second cycle and the third cycle, wherein the first cycle is the target cycle. It should be noted that the first cycle, the second cycle and the third cycle are three consecutive sampling cycles, and the sampling time of the first cycle is the earliest, and the sampling time of the third cycle is the latest.

[0084] The first operating parameter and the second operating parameter both include at least one of the operating temperature of the hard disk, disk performance parameters (for example, the average number of read / write (I / O) operations per second (Input / Output Operations Per Second, IOPS), read / write parameters (for example, average read / write latency), current wear and tear, and the number of bad blocks.

[0085] The storage pool refers to a hard disk array constructed by multiple solid-state hard disks. For example, the storage pool is constructed using Redundant Array of Independent Disks (RAID) technology. Multiple SSD storage devices in the storage pool organize storage units in the form of strips. On the one hand, the manufacturing process and other characteristics of each SSD in the storage pool are different. On the other hand, some characteristic factors of multiple SSDs in the same stripe have similar characteristics. The remaining life of each SSD fluctuates continuously with changes in these characteristics.

[0086] In an embodiment of the present application, when it is necessary to estimate the remaining life of any solid-state hard disk (i.e., the target hard disk) in the storage pool, the first operating parameters of the target hard disk in the first cycle, the second cycle, and the third cycle, as well as the second operating parameters of all hard disks in the storage pool in the first cycle can be obtained.

[0087] Optionally, the first operating parameters of the target hard disk in the first sampling period, the second period and the third period can be obtained through the SMART information of the target hard disk, and the second operating parameters of each hard disk in the storage pool in the first period can be obtained through the SMART information of each hard disk in the storage pool.

[0088] Optionally, the operating parameters of each hard disk in the storage pool collected in multiple cycles can be stored in a preset database in advance. When the remaining life of the target hard disk needs to be estimated, the computer device can directly obtain the first operating parameters of the target hard disk in the first sampling cycle, the second cycle and the third cycle from the preset database, as well as the second operating parameters of each hard disk in the storage pool in the first cycle.

[0089] S202: Determine the life consumption of the target hard disk within a preset time period according to the first operating parameter and the second operating parameter.

[0090] In the embodiment of the present application, after obtaining the first operating parameter of the target hard disk within the preset number of cycles and the second operating parameters of all hard disks in the storage pool within the target cycle, the similarity between the first operating parameter and each second operating parameter can be determined, and the life consumption of the target hard disk within the preset time period can be determined according to the similarity that meets the preset requirements. Optionally, the similarity that meets the preset requirements can be the similarity with the maximum similarity between the first operating parameter and each second operating parameter.

[0091] S203: Estimate the remaining life of the target hard disk according to the wear parameters and life consumption of the target hard disk.

[0092] The wear parameters include the current wear degree and the maximum safe wear degree.

[0093] In an embodiment of the present application, after obtaining the life consumption of the target hard disk within the preset time period, the wear parameters of the target hard disk can be obtained, and the remaining life of the target hard disk can be determined based on the wear parameters of the target hard disk and the life consumption of the target hard disk within the preset time period.

[0094] The hard disk life estimation method provided in the embodiment of the present application obtains the first operating parameter of the target hard disk within a preset number of cycles, and the second operating parameter of all hard disks in the storage pool within the target cycle, and determines the life consumption of the target hard disk within the preset time period according to the first operating parameter and the second operating parameter, and then estimates the remaining life of the target hard disk according to the wear parameter and life consumption of the target hard disk; the preset number of cycles includes the target cycle. The above method provides an accurate hard disk life estimation method, which estimates the remaining life of the target hard disk through the operating parameters of the target hard disk and the operating parameters of each hard disk in the storage pool. Compared with the method of estimating the remaining life of the target hard disk based only on the SMART information of the target hard disk itself, the above method takes into account the mutual influence between the hard disks in the storage pool, and the certain connection between the operating parameters of the hard disks within the same sampling period, and estimates the remaining life of the target hard disk according to the operating parameters of each hard disk in the storage pool within the target cycle and the operating parameters of the target hard disk within the preset number of cycles, so that the estimation result is more accurate.

[0095] In one embodiment, Figure 2 Based on the embodiment shown, the above-mentioned preset number of cycles includes three cycles, which can describe the process of determining the life consumption of the target hard disk within the preset time period, such as Figure 3As shown, the above S202 "determining the life consumption of the target hard disk within a preset time period according to the first operating parameter and the second operating parameter" includes:

[0096] S301 : Determine a similarity parameter of a target hard disk according to a first operating parameter of the target hard disk in a second cycle and a second operating parameter of each hard disk in a target cycle.

[0097] Among them, the target cycle is the first cycle.

[0098] In an embodiment of the present application, after the first operating parameters of the target hard disk within a preset number of cycles are obtained as described above, the first operating parameters of the target hard disk within a second cycle are extracted, and the similarity parameters of the target hard disk are determined based on the similarities between the first operating parameters of the target hard disk within the second cycle and the second operating parameters of each hard disk within the first cycle.

[0099] Optionally, among the similarities between the first operating parameter of the target hard disk in the second cycle and the second operating parameters of each hard disk in the first cycle, the similarity that meets a preset condition may be determined as the similarity parameter of the target hard disk.

[0100] S302: Determine a first mapping parameter of the target hard disk according to the first operating parameter of the target hard disk in the second cycle, the duration of the second cycle, and the similarity parameter.

[0101] In an embodiment of the present application, after the first operating parameters of the target hard disk in the second cycle and the similarity parameters of the target hard disk are obtained as mentioned above, the duration of the second cycle can be obtained, and the first mapping parameters of the target hard disk can be determined based on the first operating parameters of the target hard disk in the second cycle, the similarity parameters of the target hard disk and the duration of the second cycle.

[0102] S303: Determine the life consumption of the target hard disk within a preset time period according to the first mapping parameter, the similarity parameter, the first operating parameter of the target hard disk in the third cycle, and the duration of the second cycle.

[0103] In an embodiment of the present application, after the first mapping parameters of the target hard disk, the similarity parameters of the target hard disk, and the first operating parameters of the target hard disk within a preset number of cycles are obtained, the first operating parameters of the target hard disk within a third cycle can be extracted from the first operating parameters of the target hard disk within the preset number of cycles, and the duration of the second cycle can be obtained, and the life consumption of the target hard disk within the preset time period can be determined based on the first mapping parameters of the target hard disk, the similarity parameters of the target hard disk, the first operating parameters of the target hard disk within the third cycle, and the duration of the second cycle.

[0104] The method for determining the life consumption of a target hard disk within a preset time period provided in an embodiment of the present application determines the life consumption of the target hard disk within the preset time period based on the similarity between the first operating parameters of the target hard disk in the second cycle and the second operating parameters of each hard disk in the target cycle, thereby providing a data basis for subsequently determining the remaining life of the target hard disk based on the life consumption of the target hard disk within the preset time period.

[0105] In one embodiment, Figure 3 Based on the embodiment shown, the process of determining the similarity parameter of the target hard disk can be described as follows: Figure 4 As shown, the above S301 "determine the similarity parameter of the target hard disk according to the first operating parameter of the target hard disk in the second cycle and the second operating parameter of each hard disk in the target cycle" includes:

[0106] S401: Determine the similarity between the first operating parameter and each second operating parameter.

[0107] In the embodiment of the present application, after the first operating parameter of the target hard disk in the second cycle and the second operating parameters of each hard disk in the target cycle are obtained, the similarity between the first operating parameter and each second operating parameter can be determined.

[0108] Optionally, in the embodiment of the present application, the similarity between the operating parameters can be determined by using the Pearson correlation coefficient. The similarity between the operating parameters can be expressed by the following formula (1):

[0109]

[0110] in, is the similarity between the first operating parameter of the target hard disk in the second cycle and the second operating parameter of any hard disk in the storage pool in the first cycle, is the number of parameters in the first operating parameter and the second operating parameter. For example, when the first operating parameter and the second operating parameter both include the operating temperature of the hard disk, disk performance parameters (for example, the average number of read / write (I / O) operations per second (Input / Output Operations Per Second, IOPS), read / write parameters (for example, average read / write latency), current wear and the number of bad blocks, is 5. is one of the first operating parameters of the target hard disk in the second cycle, is the average second operating parameter of the target hard disk in the second cycle, is one of the first operating parameters of the target hard disk in the first cycle, is the average second operating parameter of the target hard disk in the first cycle.

[0111] Optionally, when both the first operating parameter and the second operating parameter include the operating temperature of the hard disk, disk performance parameters (for example, the average number of read / write (I / O) operations per second (Input / Output Operations Per Second, IOPS), read / write parameters (for example, average read / write latency), current wear and the number of bad blocks, for the operating parameter of the operating temperature of the hard disk, the operating temperature of the target hard disk in the second cycle and the operating temperature of each hard disk in the first cycle can be obtained, and the similarity between the operating temperature of the target hard disk in the second cycle and the operating temperature of each hard disk in the first cycle can be obtained. Correspondingly, for the operating parameter of the hard disk read / write parameter, the read / write parameters of the target hard disk in the second cycle and the read / write parameters of each hard disk in the first cycle can be obtained, and the similarity between the read / write parameters of the target hard disk in the second cycle and the read / write parameters of each hard disk in the first cycle can be obtained. It should be noted that for other operating parameters, the acquisition method consistent with the similarity of the above-mentioned operating parameters is adopted to obtain the similarity of other operating parameters.

[0112] S402: Determine the similarity between the second operating parameter with the greatest similarity and the first operating parameter as a similarity parameter.

[0113] In the embodiment of the present application, after the similarities between the first operating parameter and each second operating parameter are obtained, the similarity between the second operating parameter with the greatest similarity and the first operating parameter may be determined as the similarity parameter.

[0114] Optionally, after obtaining the operating temperature of the target hard disk in the second cycle and the similarity between the operating temperatures of each hard disk in the first cycle, the similarity between the operating temperature of the target hard disk in the second cycle with the greatest similarity and the operating temperatures of each hard disk in the first cycle is determined as the similarity parameter of the operating temperature.

[0115] Optionally, after obtaining the read and write parameters of the target hard disk in the second cycle and the similarity between the read and write parameters of each hard disk in the first cycle, the similarity between the operating temperature of the target hard disk with the greatest similarity in the second cycle and the operating temperature of each hard disk in the first cycle is determined as the similarity parameter of the operating temperature.

[0179] Alternatively, if Fig. 9 As shown below, a schematic diagram of the method for estimating the life of a hard disk is also provided, including (it should be noted that Fig. 9 The MLLEE model in the figure is the method for estimating the hard disk life in each of the above embodiments):

[0180] 1) Create an experience pool and initialize it. If there is a historical record, the experience pool needs to be restored based on the historical record. Each hard disk in the experience pool contains five dimensions: temperature, average IOPS, average read and write latency, current cycle wear, total wear, and number of bad blocks;

[0181] 2) Set the maximum safe wear of the hard disk. Normally, the maximum safe wear is 90% of the initial wear of the hard disk.

[0182] 3) Determine whether the wear degree of the SSD in the storage pool has reached the maximum safe wear degree. If so, set the SSD to read-only mode to prevent damage to the SSD caused by writing. If not, execute the following steps 4)-7);

[0183] 4) Set a timer for sampling, for example, sampling every 5 seconds, obtain wear and temperature information through SMART, obtain performance data through the storage pool, record the sampling results of the current cycle, the sampling period is 5 minutes, and count the parameters of each hard disk in five dimensions, including temperature, average IOPS, average read and write latency, wear in the current cycle, total wear, and number of bad blocks;

[0184] 5) Based on the parameters of each hard disk including temperature, average IOPS, average read / write latency, current cycle wear, total wear, and number of bad blocks, the above hard disk life estimation method is executed to obtain the remaining life of the hard disk;

[0186] 7) When the user terminal queries the remaining life of a certain SSD, the main controller thread queries the remaining life of the SSD and returns the result to the user terminal.

[0187] The above method provides an accurate method for estimating the life of a hard disk. The remaining life of the target hard disk is estimated through the operating parameters of the target hard disk and the operating parameters of each hard disk in the storage pool. Compared with the method of estimating the remaining life of the target hard disk based only on the SMART information of the target hard disk itself, the above method takes into account the mutual influence between the hard disks in the storage pool and the certain connection between the operating parameters of the hard disks within the same sampling period. The remaining life of the target hard disk is estimated based on the operating parameters of each hard disk in the storage pool within the target period and the operating parameters of the target hard disk within a preset number of periods, so that the estimation result is more accurate.

[0192] When a user terminal needs to obtain a real-time life estimate, if the user terminal is connected to a slave controller, the user terminal first sends a request to obtain the remaining life to the slave controller, and then the slave controller forwards the request to obtain the remaining life to the master controller, and the master controller executes the above Figure 2-Figure 8 After the hard disk life estimation method of the illustrated embodiment is implemented, the remaining life of the hard disk is obtained, and the remaining life of the hard disk is forwarded to the user terminal via the slave controller.

[0193] If the user terminal is connected to the main controller, the user terminal directly sends a request to obtain the remaining life to the main controller, and the main controller executes the above Figure 2-Figure 8 After the hard disk life estimation method of the illustrated embodiment is performed, the remaining life of the hard disk is obtained and the remaining life of the hard disk is directly sent to the user terminal.

[0194] In addition, when an abnormal situation occurs in the main controller, a slave controller can be selected from multiple slave controllers as the new main controller, and the original main controller can be downgraded to a slave controller. The program product of the hard disk life estimation method can be reinitialized on the new main controller, the historical records can be restored, and the above-mentioned user terminal acquisition steps can continue to be executed.

[0196] The hard disk life estimation system provided in the embodiment of the present application realizes the function of sending the remaining life of the target hard disk to the user terminal through the interaction between the user terminal and the controller. That is, when the user needs to obtain the remaining life of the target hard disk, he only needs to send a request to the background controller to achieve it, which is convenient and fast, and improves the user experience.
