Abstract
Extents of data are promoted or demoted between hierarchical storage tiers based on temporal locality of access captured with a primary count-min-sketch based on monitored input-output commands. Extents may also be promoted based on spatial locality of access captured with a secondary count-min-sketch based on the monitored input-output commands. The count-min-sketches may be implemented in a tiering engine of a storage array or in the flash translation layers of solid-state drives. The flash translation layers may generate tiering hints that are provided to a tiering engine.
