HARD DISK DRIVE (HDD) EARLY FAILURE DETECTION IN STORAGE SYSTEMS BASED ON STATISTICAL ANALYSIS

In one embodiment, a system includes a processor and logic integrated with and/or executable by the processor, the logic being configured to detect a failure event indicating possible failure of a storage device, initiate a rebuild for the storage device which experienced the failure event, receive information about the storage device which experienced the failure event, and apply a set of statistical process control rules to the information to determine whether the failure event is statistically abnormal. Other systems, methods, and computer program products for providing early warning of storage device failure are also described in additional embodiments.
