Just one 10GE link? Probably not. Are you afraid that 10 GE is "overkill" and in what sense? If your requierements can be filled with a few 1GE links and as long as that is cheaper than two 10 GE's, nobody is expecting anybody to buy 10 GE, right? Today the biggest impact of 10 GE on storage decisions is: it's there if we ever need it, the ceiling is way up. Every bottle has a neck. I think we just want it to be the most expensive part of the system, not a 5% cost item. For storage, that should be the drives, although some people try to make the software licensing to be the crown jewel. Darwin, Tom,
