Michael Fahey, Director of Product Management, Hitachi Data Systems

Single Instance Storage (duplicate elimination) has become a very popular topic in the industry because of the potentially large reduction in cost and increase in efficiency it offers. Various technologies are being promoted for different tasks including backup, archiving, and transactional storage. Each of these storage uses represents a unique set of challenges and the single instancing technology being implemented has major implications for scale, performance, and functionality. Single Instance Storage also has long term legal and compliance implications for records management. This session will review various technologies available including object level de-duplication, fixed block de-duplication, and variable length block de-duplication and the implications of each for backup, archive, and transactional storage."
