Storage apparatus and method for autonomous space compaction

摘要: Embodiments of the inventive concept improve performance, energy efficiency, and capacity storage solutions, for example, by reducing data movement between CPU device increasing available underlying devices via in-storage support compaction. include a apparatus method autonomous space compaction initiated host-side command according to metadata specified host. A compact engine can function as an independent module or logic section within device, which migrate thereby freeing up making preexisting more compact. The cause self operations, trim move and/or merge operations. notify host completion
