Method and system for reduced data movement compression using in-storage computing and a customized file system

Abstract:

One embodiment facilitates data compression. During operation, the system receives, by a host computing device, a request to write a first set of data. The system writes the first set of data to a first storage device of a storage component. A storage component controller performs compression on the first set of data to obtain compressed data. The controller transmits, to a file system component of the host computing device, metadata associated with the compressed data. The file system component inserts in a journal an entry based on the metadata associated with the compressed data. The system writes, by the controller, the compressed data to a second storage device of the storage component, thereby enhancing performance of the host computing device by reducing a number of data transfers involved in compressing and writing of the first set of data.
