Method and device of dynamically diagnosing hard disk failure based on S.M.A.R.T (Self-Monitoring Analysis and Reporting Technology) data

Abstract

The invention discloses a method and a device of dynamically diagnosing hard disk failure based on S.M.A.R.T (Self-Monitoring Analysis and Reporting Technology) data and relates to the field of data storage security diagnosis. The method comprises the following steps: 101) establishing a cloud storage server side to continuously collect three types of data; 102) establishing a hard disk failure early-warning dynamic model; 103) establishing S.M.A.R.T parameter normal fluctuation curves and ranges; 104) obtaining a health diagnosis scoring dynamic model through big data analysis. The method and the device of dynamically diagnosing hard disk failure based on S.M.A.R.T data have the following beneficial effects: 1) the cloud storage server side is established to continuously collect data related to health of hard disks; 2) the collected data are organized to establish the hard disk failure early-warning dynamic model, the S.M.A.R.T parameter normal fluctuation curves and ranges and the health diagnosis scoring dynamic model; 3) the correctness of the model is continuously improved through machine learning in hard disk failure diagnosis.

Description

technical field [0001] The invention belongs to the field of data storage safety diagnosis, and relates to a method and a device for dynamically diagnosing hard disk faults based on SMART data. Background technique [0002] S.M.A.R.T.: The full name is "Self-Monitoring Analysis and Reporting Technology", that is, "self-monitoring, analysis and reporting technology". Condition monitoring, when an abnormality occurs, a warning will be issued. [0003] Cloud storage (CloudStorage): It is a new concept extended and developed from the concept of cloud computing (Cloud Computing). A system that integrates a large number of different types of storage devices in the network to work together through application software to jointly provide data storage and business access functions. [0004] Normalization: also known as data standardization, is a method of simplifying calculations, that is, transforming dimensional expressions into dimensionless expressions and becoming scalars, whi...

AI Technical Summary

Problems solved by technology

[0007] 1. Simply read the S.M.A.R.T. information from the reserved area of ​​the hard disk system, and display it in the form of a list, which many non-professional users cannot understand;

[0008] 2. Only the current value of each item of S.M.A.R.T. information cannot be collected and sorted into a historical curve for more accurate diagnosis;

[0009] 3. It is impossible to solve the problem that the S.M.A.R.T. items, attributes and descriptions of different master controllers and different models of products of different hard disk manufacturers are not the same on SSD solid state drives;

[0010] 4. For predictable hard disk dangers, the warning time lags behind, or there is no active warning;

[0011] 5. False warnings cannot be corrected
