Everybody's talking about the green data center, but the fact is that few are actually doing it. This is no surprise, considering we're talking about revamping infrastructures and design concepts that have guided the enterprise practically since its inception. And while most existing centers are cutting power costs by updating to new green technologies like virtualization and energy-efficient storage systems, big savings can also be found in heating and cooling, some of which can be realized only by building an entirely new structure from the ground up. So in that light, I'd thought I'd draw some attention to the green technology going into the newest data centers to hopefully give people an idea of what their future operations might look like.
