From what I've been told in the past, no, because the comms link protocols between storage servers are proprietary. It means you can't flashcopy or or hyperswap between volumes from different vendors, it's one of the reasons TDMF exists In theory, all things are negotiable, so I suppose that could change, but if it has, I haven't seen anything about it. (Don't read too much into that.) If the status had changed, I would expect the vendor to be hawking that level of compatibility loudly as a differentiator. I wouldn't expect IBM to say anything, as it's up to the vendor to make compatibility claims, so the best answer would come from the vendor storage specialist. Sorry I can't give you more definitive information. I'll check with a storage architect and see if I can get a better answer.
