There is a presentation out on the web from the Oxford 2007 Symposium about TSM dedup. From reading it, I'm sure just how useful it will be. It only supports FILE devices (files are re-duplicated when written to tape) and duplicate blocks are not removed until reclamation (you don't get the benefit for a long time). I also do not see an option for compression on top of the dedup like a VTL or dedup appliance provides.
