Problems solved by technology

This results in additional performance loss
Additionally, compressing information on a block-based drive requires a lot of background activity to track the locations of the blocks of the target file, compress and assemble those locations into new blocks, and then update the mapping table to show the location of the compressed and stored information. The new location, which may have substantially changed during the compaction

Abstract

Embodiments of the present invention include a compression system including one or more compressibility inputs; a compression predictor configured to predict the compressibility of data based on the one or more compressibility inputs; a compressor configured to compress the data; and one or more compression inputs. At least one of the compression predictor or the compressor is configured to determine how to compress the data based on the one or more compression inputs. The one or more compressibility inputs comprise at least one of an object extension dictionary, an object signature dictionary, and an entropy estimation algorithm library. The one or more compression inputs comprise at least one of a quality of service profile, a device performance profile and a compression algorithm performance chart.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 522,423, filed June 20, 2017, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The inventive concept relates to a storage system, and more particularly to a compression system having a compression predictor for predicting the compressibility of data and a compressor for compressing data based on the prediction, a compression system comprising the Drivers of the compression system and a method for predicting and compressing data are disclosed. Background technique [0004] Compressing data is an effective way to increase the efficient use of data storage capacity. However, not all compression algorithms are created equal. Some compression algorithms work better with certain types of data than others, and in general, compression algorithms trade compression ratio for time / processing. ...
