Abstract
A data store is accessed that stores a collected historical record of performance metrics for input/output operations executed at a storage device that is part of a group of storage devices that are configured to provide a fault resiliency function. A performance profile is determined for the selected storage device based on selected performance metrics of the historical record. A difference between the performance profile for the storage device and a characteristic performance profile for similar storage devices is determined. When the difference exceeds a predetermined deviance threshold, selected I/O requests designated for the selected storage device are redirected to another device of the group of storage devices.
