IBM has published a marketing video about their ProtecTIER data deduplication system recorded at the Pulse09 conference in February:
Key message: It is scalable. But the video contains 3 minutes of marketing stuff without much real information.
What I really find more interessing: At the SYSTOR'09 conference (one of the interessing talks I mentioned here) will be a research talk about the technology and concepts behind the ProtecTIER system, which is based on the product from the company Diligent that IBM bought April 2008. Abstract:
We describe some of the design choices that were made during the development of the IBM TS7650G ProtecTier, a fast, scalable, inline, deduplication device. The system's design goals and how they were achieved are presented. This is the first and only deduplication device that uses similarity matching. The paper provides the following original research contributions: we show how similarity signatures can serve in a deduplication scheme; a novel type of similarity signatures is presented and its advantages in the context of deduplication requirements are explained. It is also shown how to combine similarity matching schemes with hash based identity schemes.I really look forward to this talk. Especially how the delimit their approach in comparision to approaches like DERD, DeepStore and other.
