The data center is an area of IT that can reap benefits from using greener and cleaner technology, but experts who gathered in New York recently said CIOs still aren't doing enough to help the environment or their businesses by using green technology practices in their facilities.

It might surprise some CIOs how inefficient data centers still are when it comes to energy consumption, as many look and operate the same as they have for years, said Ruth Harenchar, vice president of Consulting Services at TechnoDyne, a privately held strategic technology consultant.

"The legacy data center is amazing to me," said Harenchar, who has seen her share of data centers during her more-than-20-year career. "If you have seen one data center, you have seen all that ever existed."

Harenchar was one of several experts speaking at the "CIO as Data Center Optimizer: Green Tech and Evolving Software Applications" conference at the Polytechnic Institute of New York University in Brooklyn. Attendees at the daylong conference pondered ways CIOs can use green technology practices to improve the performance of data centers and cut energy costs.

Harenchar and others noted that energy inefficiency is a major pain point for CIOs when it comes to the data center, and they offered suggestions for how this problem might be remedied.

Cheemin Bo-Linn, CEO of Peritus Partners, pointed out that a company's data center typically takes up about 2 percent of its facilities space, but uses 40 percent of the energy. However, by using virtualization technology so fewer physical pieces of hardware are used in the data center, and by buying electricity according only to the data center's need -- among other strategies -- CIOs can reduce this energy footprint.

"Energy-efficient solutions make good business sense," Bo-Linn said. "But these solutions must have a credible, measurable path to profitability, be sustainable and [be] facilitated by favorable regulations.“

It is imperative that CIOs begin taking action sooner rather than later to achieve more energy efficiency because the industry as a whole is moving to adopt green technology, she said. "The current trajectory is one that is not sustainable," Bo-Linn said. "the pressures of change are going to continue to be there."
