STORAGE APPARATUS AND METHOD FOR AUTONOMOUS SPACE COMPACTION

摘要

According to an embodiment of the present invention, by reducing data movement between the central processing unit and the storage device and increasing the usable capacity of the storage devices through in-storage support for data compression, the performance, energy efficiency, and capacity of storage solutions can improve Embodiments include an autonomous in-storage device and method for compressing an autonomous in-storage space, initiated by a host-side command and according to metadata specified by the host. The spatial compression engine can function as an independent module or logic section within the storage device. The storage device may move data therein. Thereby, the capacity can be freely increased, and the existing data can be further compressed.
