Slideshow: 5 Tools to Prevent Energy Waste in the Data Center

What does a real green data center look like?

Officials at Viridity Software -- the name means "greenness" -- argue that today's power monitoring products focus only on the physical infrastructure, giving insight into how power is delivered to the data center but not insight into why it is being consumed.

Viridity's software maps the connections between applications and specific IT equipment, while also analyzing the relative importance to the business of each application. Then it provides step-by-step recommendations to eliminate power and cooling inefficiencies, simulates the potential impact of new technology deployments and enables chargeback.

"They take an application-based view," says David Hill, an analyst with the Mesabi Group. "It's much more sophisticated and much more elegant [than current power monitoring products]. It's the way it should be done."

Analysis tools that look solely at the power usage of servers and other infrastructure aren't necessarily helpful in controlling energy use, because they don't analyze the amount of power the business needs to operate effectively, Hill says.

"If you just look at infrastructure you can't always understand what's happening, and know what energy each application is using," he says.

Viridity was founded in 2007 and has financing of more than $7 million from Battery Ventures and North Bridge Venture Partners. The company was founded by CTO Michael Rowan, who founded continuous data protection vendor Revivio, which was acquired by Symantec three years ago; and vice president of engineering Chris Rocca, also a veteran of Revivio.Viridity is still searching for a CEO. For now, board chairman Dave Lemont is serving as interim CEO.

Viridity has eight customers so far and will make its software generally available at the end of March. The product is a software download combined with a hosted database, and prices can run anywhere from a few thousand dollars to hundreds of thousands, depending on the size of deployment.

Before founding Viridity, Rowan says he was consulting for large companies struggling to provide power to IT equipment. One company bought millions of dollars worth of disk drives and attempted to install them when "someone said 'you can't plug them in because there's not enough power.'" That made Rowan realize how little information companies have about how power use relates to business processes.
