Firms with datacentres could save from $100,000 to $275,000 per year on every megawatt of IT infrastructure by using fresh air cooling systems, according to Dell.
Dell claims that the use of fresh air cooling in place of conventional chilled air systems is set to expand as firms look to cut the cost of operating datacentres. The move is also being driven by new legislation in the US and Europe aimed at curbing energy consumption and greenhouse gas emissions.
"It is well known that cooling can account for as much as 30 percent of datacentre operating costs, so many customers are looking to establish new practices around how you drive datacentres," Dell's enterprise programme manager Hugh Jenkins told V3.
To this end, Dell is now running its Fresh Air initiative, offering advice and consultancy via its Datacentre Solutions (DCS) group, based on expertise garnered through custom building solutions for large enterprise customers, Jenkins said.
"One example is with eBay, where we expanded their datacentre capacity using a pre-built infrastructure module in a shipping container that we actually dropped onto the roof of their existing datacentre," Jenkins said.
However, it is new build projects that are going to see the benefit of this approach, as its success depends to a large extent on having IT equipment that is validated to operate at a higher temperature, such as Dell's own 12th generation PowerEdge servers, launched earlier this year.
"For servers, the norm is that they are warrantied for a maximum 35 centigrade, whereas the 12G servers, we have relaxed that to a maximum 45 degrees and 90 percent humidity," Jenkins explained.
