Abstract
Performance data is collected for input/output operations executed at a storage device of a plurality of storage devices of a software-defined storage network. Based on the collected performance data, a time-based I/O performance profile for the storage device is determined. A characteristic time-based I/O performance profile is determined for a representative group of storage devices having common characteristics with the storage device and based on previously collected performance data for devices of the representative group. It is determined that the difference between the time-based I/O performance profile for the storage device and the characteristic time-based I/O performance profile exceeds a predetermined deviance threshold that is indicative of a probable failure of the storage device. An indication is generated that the storage device exceeded the predetermined deviance threshold.
