Web hosting company turns to DC power to cut energy use at data centres

Netfirms is turning to direct current power as a key element in its Netfirms Green energy conservation program. Seeking to shrink its environmental footprint by reducing energy use in its data centres and corporate offices, the Toronto-based Web hosting company is in the final stages of migrating its clustered server architecture and data center operations to a direct current power source using Rackable Systems' patented DC power technology.

Netfirms says the technology has already reduced power consumption at its data centres by 25%; the centres' reduction in power use is expected to reach 45% by the end of 2007.

"DC power is the most viable method of reducing our environmental footprint. It sees more direct results than purchasing renewable energy credits," said Netfirms product manager Jason Matheson.

As part of the Netfirms Green program, the company has also reduced energy consumption in its offices by minimizing decorative lighting and raising the indoor air temperature. Its Toronto head office is a Certified Go Green Building under the Building Owners and Managers Association (BOMA) Go Green Environmental Certification program.
