SearchDataCenterTV is a new video segment that will air twice a month on Hosted by Matt Stansberry and Mark Fontecchio, the show features data center strategy experts discussing best practices, industry trends and new technologies.

Pros and cons of air-side and water-side economizers
Organizations can see big energy cost savings with the use of air-side or water-side economizers for data center cooling, but it's important to take reliability and efficiency concerns into account. In this video, IBM distinguished scientist and former ASHRAE chairman Roger Schmidt discusses the benefits and downsides of air- and water-side economizers and reveals which economizer he believes is the best option.

How the EPA's Energy Star rating system works in the data center
Kathleen Hogan, Director of the Climate Change Partnerships Division of the Environmental Protection Agency (EPA), discusses the Energy Star rating system. The EPA designed the Energy Star program to help consumers reduce the emissions of greenhouse gases, and the agency is applying its program to servers and the data center. Hogan also discusses the potential impact of a carbon cap-and-trade system on the data center.

Utiliies ramping up data center efficiency rebates
Many utility companies are now offering incentive and rebate programs for data center energy-efficiency projects. If data center managers can take advantage, it means that going green could equate to getting green back. In this episode of SearchDataCenterTV, Mark Bramfitt from Bay-area utility Pacific Gas & Electric talks about these incentive programs.

Applying energy efficiency metrics in the data center
Which energy-efficiency metrics have the most traction in the data center? The Green Grid has a lot of momentum behind the PUE, or Power Usage Effectiveness, metric. In the second episode of SearchDataCenterTV, data center design expert Julius Neudorfer weighs the pros and cons of this metric and advises how data center pros can get started with measuring energy efficiency and consumption.

What's holding back Green IT?
Data centers have been talking about going green for years -- as far back as 1997, when Amory Lovins at the Rocky Mountain Institute conducted the first data center energy efficiency design charette. The Uptime Institute has been pushing its membership to deal with the energy consumption issue for three years at its annual Symposium. In this video, we talk to Uptime Technology Services' Pitt Turner about barriers to progress after all these years -- what is keeping people from going green in IT?
