Abstract:
Techniques for determining a disk failure indicator for predicting disk failures are described herein. According to one embodiment, diagnostic parameters are received which are collected from a set of known working disks and a set of known failed disks of a storage system. For each of the diagnostic parameters, a first quantile distribution representation is generated for the set of known working disks, and a second quantile distribution representation is generated for the set of known failed disks. The first quantile distribution representation and the second quantile distribution representation of each of the diagnostic parameters are then compared to select one or more of the diagnostic parameters as one or more disk failure indicators for predicting future disk failures.
