US 12,223,176 B1 · Managing wear levels of storage devices

Abstract

A technique is directed to managing wear leveling between storage devices. The technique includes generating a wear imbalance level indicating a variance between a first wear level of a first set of storage devices and a second wear level of a second set of storage devices. The technique further includes, after generating the wear imbalance level, performing a comparison operation that compares the wear imbalance level to a predefined imbalance threshold. The technique further includes, in response to the comparison operation indicating that the wear imbalance level is above the predefined imbalance threshold, providing the first set of storage devices as a first storage tier and the second set of storage devices as a second storage tier.
