Data De-duplication for Primary Storage System

Data De-duplication has being used comprehensively within Disk-based Backups, Archives and Disaster Recovery. This technology´s high data reduction ratio and satisfied performance in secondary data storage system has aroused huge interests in other fields. The primary storage system is indeed a field being long for data reduction. Data de-duplication maybe a chance to alleviate data redundancy problem within that field. Actually, there are still lots of problems and technology challenges in resolving the contradiction between strict performance requirements in the primary storage system and the resources consuming character of the data de-duplication. This article will give an introduction about those technology challenges and propose a new data storage framework trying to improve those problems.
