Energy efficiency continues to be a major concern for data centers with raised floor systems. In the past, energy cost was simply a given, on par with the costof hardware and labor. As hardware has become more efficient and automated procedures have taken over labor, the cost of energy has continued to climb and it now represents around 25% of total operating costs for most data centers. In most data centers, one of the biggest uses of energy involves the strategic cooling of equipment in conjunction with the raised floor system. The typical data center uses nearly twice as much…
