Racktivity has raised $8 million in second-round financing for its management of data center power.
The round was led by Partech International, and existing investor Big Bang Ventures participated. The European company also announced it would open a U.S. headquarters in Redwood City, Calif. It said it will use the new round of funding to accelerate growth and expand its sales presence in Europe and the U.S.
Racktivity makes a power distribution unit called Rack Controller as well as software that manages and reduces data center energy use and maximizes uptime, or the time equipment can run without failing. The company says it will deliver the first of its modules to the U.S. in the first quarter of 2011.
Greening data centers are a growing concern for big companies. Data centers eat up around three percent of all energy consumed in the U.S., and a number of startups are competing to provide solutions ranging from wireless centers to energy management software to networked lighting.
Racktivity has deployed its Rack Controller in Europe through companies like Combell, Terremark Europe and Zenith Infotech. Combell, a data center hosting company, reported lowering its total cost of ownership by 65 percent.
