This article is full of factual errors. The IBM servers aren't "turned sideways". They're simply shallow depth servers in a side by side configuration. They're still cooled front to back like a traditional server. The entire rack's power consumption isn't 100 watts. It's based on configuration and could easily run 25-30kw. And comparable servers don't necessarily draw more power. IBM has simply cloned what Rackable Systems has been doing for the past 8 years. Dell and HP also caught on to the single power supply, non-redundantly configured servers over the past few years. IBM certainly has a nice product but it's not revolutionary.
