I wrote a blog article previously about IBM being upset about the Sun Oracle deal and throwing a bit of a tantrum. Sun apparently has some not so nice things to say about the innovation at IBM. From the article on Sun's website. "Industry experts frequently talk about the "Brick Wall" of Computing Performance. Well, everyone except IBM. Cranking the clock frequency to scale performance is an evolutionary dead-end; while Sun and the industry as a whole move forward with multi-core, multi-thread processors. IBM is the last holdout and is exhausting the old technique with higher power consumption and higher heat generation."The article makes quite a few valid points and hits IBM where it really hurts. If you look at the slanted design of the racks for the IBM Blue Gene Supercomputer this was done to house additional air ducts for cooling. IBM is pushing for water cooled designs to further cool these really hot processors which is directly opposite of the industry's air cooled movement. Even Cray moved away from liquid Fluorinert cooling in their later designs.
Unlike IBM with their incentive paid in professional services "blue dollars" Sun is offering a 40% discount on hardware replacing IBM systems.
