Abstract
A technique for promoting storage efficiency in a data storage system decouples data-set sizes used for compression from those used for deduplication, by performing deduplication at extent-level granularity but performing compression on aggregates that contain multiple extents. Compression and deduplication can each work on data-set sizes that are more optimal for the respective features, thereby avoiding the need to settle on a compromise that is not particularly well-suited to either of them.
