| 发明名称 | System and method for predicting single-disk failures | ||
| 摘要 | Techniques for predicting single-disk failures are described herein. According to one embodiment, first values of a predetermined diagnostic parameter collected from a set of known working disks and a set of known failed disks of a storage system are received. An optimal threshold of the received first values of the predetermined diagnostic parameter is determined based on a quantile distribution of the first values against a plurality of threshold candidates. A potential risk of disk failures of one or more disks of a target storage system is determined based on second values of the predetermined diagnostic parameter collected from the one or more disks of the target storage system in view of the optimal threshold. | ||

| 主权项 | 1. A computer-implemented method for predicting disk failures, the method comprising: receiving first values of a predetermined diagnostic parameter collected from a set of known working disks and a set of known failed disks of a storage system; generating a quantile distribution graph based on the first values; determining an optimal threshold of the received first values of the predetermined diagnostic parameter based on a quantile distribution of the first values against a plurality of threshold candidates, wherein the quantile distribution of the first values is derived from the quantile distribution graph; and determining a potential risk of disk failures of one or more disks of a target storage system based on second values of the predetermined diagnostic parameter collected from the one or more disks of the target storage system in view of the optimal threshold. | ||
