Abstract: In a data storage system that includes two or more storage engines in interconnected by a channel-based fabric, highly deduplicated data is identified and promoted to a dedupe performance tier characterized by mirrors on each of the storage engines. Blocks of deduplication data are scored based on reference counts and read-miss access patterns. Promotion of blocks to the dedupe performance tier and demotion of blocks from the dedupe performance tier are calculated based on the scores. Performance is enhanced by enabling highly deduplicated blocks to be accessed from engine-local memory and engine-local storage via switches rather than the channel-based fabric.
