Embodiment 1

[0040] The following introduces Embodiment 1 of a life prediction method for a solid-state hard disk provided by the present application, see figure 1 , embodiment one includes:

[0041] S101. Obtain the medium wear index and time stamp of the target solid state disk within a preset time range;

[0042] This embodiment is mainly used for predicting the service life of a solid state disk, which is a Solid State Drive, SSD for short. Specifically, you can use the smartcl-a command in the smartctl tool to obtain the S.M.A.R.T. parameters of the solid-state drive according to the preset cycle, and record the smart_233 Media Wearout Indicator and timestamp in the S.M.A.R.T. parameter to the target csv file, where smart_233 Media Wearout Indicator That is, the medium wear index in this embodiment. The full name of S.M.A.R.T is Self-Monitoring Analysis and Reporting Technology, that is, self-monitoring, analysis and reporting technology. Solid-state drives that support S.M.A.R.T te...

Embodiment 2

[0053] see figure 2 , embodiment two specifically includes:

[0054] S201. Collect the S.M.A.R.T. information of the target solid state disk according to a preset cycle;

[0055] S202. Determine the medium wear indicator and time stamp of the target solid state disk according to the S.M.A.R.T. information, and store them in the target csv file;

[0056] The above preset cycle can be adjusted according to actual needs. When the above preset cycle is every day, use the smartcl–a command in the smartctl tool every day to obtain the S.M.A.R.T. The media wear metrics of an embodiment are recorded into the target csv file along with their timestamps. In this embodiment, the target csv file is a pre-created file used to store the medium wear indicator and time stamp of the target solid-state disk.

[0057] S203. After the data volume of the csv file reaches a certain amount, obtain the media wear index and time stamp within the first preset time range as a training set; and obtai...

Abstract

The invention discloses a solid state disk life prediction method, device and apparatus and a readable storage medium. According to the scheme, a medium abrasion index and a timestamp of a solid statedisk within the preset time range are obtained by utilizing physical characteristics that programming and erasing cycle index of the solid state disk is fixed. A prophet model is constructed based on the medium abrasion index and the timestamp so as to predict the service life of the solid state disk. The prophet model can detect the trend change, periodic change and holiday change of the wear degree of the solid state disk. Compared with a simple linear formula, scene adaptability is stronger, so that service life of the solid state disk can be accurately predicted, a user is assisted to know the service condition of the solid state disk, loss caused by damage of the solid state disk is avoided, and safety of data in the solid state disk is remarkably improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a life prediction method, device, equipment and readable storage medium of a solid-state hard disk. Background technique [0002] Servers in data centers are increasingly using flash-based solid-state drives (SSDs) as high-performance alternatives to hard drives. Compared with HDD, the advantages of solid-state hard disk are: fast startup, fast read and write speed, shockproof and drop resistance, no noise, etc. However, the service life of solid-state drives is limited, and data stored in solid-state drives is difficult to recover after loss. If the service life of solid-state drives can be predicted and the damaged solid-state drives can be replaced before a failure occurs, it is of great significance to the stability of the data center. [0003] Most storage providers currently on the market, such as Intel, IBM, Micron, Samsung, Huawei, etc., use a simple linear f...
