Sonic.net CEO Dane Jasper explains on his blog:

We have replaced our traditional Liebert data center AC units with a huge new system from Bell Products of Napa. Bell’s been working on this project for over a year for us, and it’s a massive update. The new system adds a huge amount of capacity, and reduces power usage by a shocking amount.

In an earlier post, he discusses some of the economic benefits.

The largest of these is a change from our Liebert datacenter AC systems over to a new chiller plant from Bell Products of Napa. This project, a $600,000 investment, will result in large energy savings. Because of it's efficiency, and the fact that we're retiring the far less efficient Liebert equipment, this project has been approved by PG&E for a rebate of about $110,000. That’s great news for the environment!

Yes it is. More efficient cooling is just one way to green up that data center, and as you can see, there are incentives that can help ease the transition.

Thanks Alex!
