the ultimate challenge in Data Centers design
Increased data exchange causes also a dramatic power consumption increase in modern data centers. In 2001 the world energy consumption of data centers will be around 100 billion kWh, compared to 61 billion in 2006.
Energy supply and efficiency becomes therefore a crucial aspect of these infrastructures, both as concerns the possibility to build the data center, as well as regards operating costs and sustainability.
Reduced operating cost
The growing energy demand in modern Data Centers implies that every energy improvement allows to obtain a significant OPEX (operating costs) improvement. In infrastructures working 365 days per year, for an average time of 10 years, this represents by far the largest part of Data Centers overall costs.
Running out of power capacity
Many utilities, especially in crowded urban areas, can not deploy more servers because power feeds are at capacity. In these cases to improve energy performances of the whole structure, is the first a condition to keep running the Data Center.
A green, energy efficient approach to data center has positive implications also for space optimization. It allows a more effective use of the data center concentrating cooling units along the walls, reducing the waste due to cooling dispersion and delaying the need of building new rooms.
Growing digitalization and consequent energy consumption transform Data Center in a very critical application also as concerns TEWI. Hence an intelligent energy management, is crucial not only for profitability but also for sustainability.
