Today I attended Google's Efficient Data Centers Summit at their Mountain View, CA Campus. They unveiled how they achieved their average PUE of 1.21 across their six large datacenters. It was great that they were sharing information with the public around how they measured and the innovations they have. For cooling it was pretty simple. Closely coupled cooling, raising the temperatures in the datacenters and utilizing economizers.
I think this is the type of thinking that really changes the game. When you take away the constraints, you can then come up with innovation solutions. Granted that this is not the single answer to the datacenter problems, it is a very real solution to a very real problem. Google has the money and the clout to make things like this happen (imagine the PS and motherboard suppliers that had to change their design to deliver for Google).
I applaud Google's effort and look forward to further innovations. Now, if they would just let the world actually walk into their datacenters. A virtual tour video is nice, but there is nothing better than seeing it first hand. Sun has been doing that for the last two plus years. We show what works and what doesn't. That goes a long way.
So Google, let me know when I can come and see your Data Center! I'm sure it has got to be one of the coolest batcaves in the industry!
