Embodiment Construction
[0038] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0039] The disk failure prediction method of this embodiment refers to extracting various features of disk SMART indicators by means of time series data processing, and using machine learning algorithms and related theories to establish a binary classification model to predict disk status. The flow of the disk failure prediction algorithm in this embodiment is as follows: figure 1 shown. Including the following key technical links:
[0040] Step 1: Data Collection
[0041] The data set provided by Backblaze is preferred. This data set contains monitoring data of more than 30,000 disks for more than 17 consecutive months. When the disk stops working, does not respond to commands, or the RAID system reports that it cannot be read or written, it will be marked as positive Sample (i.e....
