IDGNS: There's a big emphasis on "green" data centers in North America. Is that as prevalent in emerging markets?

J.K.: We see that emphasis for the most part in America and Western Europe. In Brazil there was a lot of talk about outside-air cooling even in fairly humid environments. But it seems less of a driver in some of the emerging markets because of that rush to market. They need to get that data center up and running to meet the demand.

IDGNS: And it can take longer to choose a green solution and design the data center around it?

J.K.: Yes, and the operational experience might not be there for some of the emerging technologies.
