Data centers need power. And, as the adoption of online services, mobile apps and cloud services is growing with a fast pace, the demand for power is growing too. Coupled with rising energy prices, this trend is creating impetus to maximise efficiency.
We already explained, that energy efficent UPS is definetly helps to reach these goals. For further insights on this issue we recommend an article at UPSpower.co.uk (“How to minimise UPS contribution to data centre energy demand”). The authors deal with the benefits of scalable and modular design for rightsizing a UPS system:
“Rightsizing a UPS system yields energy savings because the more fully a UPS is loaded, the more efficiently it operates. Modular topology’s contribution to system rightsizing is particularly apparent where UPS redundancy is essential – a usual requirement in today’s data centre environment. Consider for example a load of 400 kVA. Using a standalone system, redundancy would be achieved using two 400 kVA modules, each of which would be working at 50% loading under normal conditions. Using a modular approach, the same load could be supported, with N+1 redundancy, using eleven 40 kVA rack mounted modules – each operating at over 90% loading. This improves efficiency from 90% to 95%, and reduces cooling costs.”
According to the article the total savings over five years can amount to over US$ 130.000 an 475 tonnes CO2. However, this technology offers more advantages: Combined with the reduction in UPS size and weight, a rack mounting module rather than a floor standing unit becomes viable.
“Physically, the rack’s footprint is two to three times less than a traditional system’s, and the transformerless design is much lighter also. This saving is usually extremely welcome in increasingly space-challenged data centres, as well as reducing transportation and installation costs. Overall, the reduced installation costs and lifetime energy savings add up to a significantly reduced total cost of ownership.”
