In this post Julius discusses some of the innovations that are cropping up in forward thinking data center design ranging from the adoption of Yahoo’s chicken coop architecture that is suited for utilizing ambient air cooling; new server designs optimized for hot aisle/cold aisle architecture; and innovative approaches to power supply. While most operators do not have the deep pockets and resources of players like Facebook, Google, Yahoo or Amazon — all mentioned in this post — the kinds of forward thinking innovations being pioneered by these companies are bound to have a wider impact.

Could Ice Help Data Centers Be Green?

Can Off-peak Air Conditioning (OPAC) technology, improve the green energy profile of data centers? One of the major energy consumption categories of data centers is their need to keep all of their rows of rack mounted servers operating within their critical temperature parameters. Many various techniques are increasingly being adopted by data centers around the world in order to lower their overall cooling needs. An additional technology exists that I believe can help data centers improve their energy usage profiles by shifting energy demand to off-peak hours and in so doing significantly lower their energy consumption during critical periods of peak demand. Off-peak Air Conditioning (OPAC) technology is a way for data centers to improve their peak energy demand profile.
