Power and cost aware distributed load management

The continuously rising energy demand of data centers has already reached the two-digit megawatt area by now. The rising energy costs force operators to search for effective methods for energy reduction. A popular, software based instrument is consolidation using virtualization, since this provides also high flexibility for changing business requirements. Dynamic load management can introduce an even stronger consolidation here. An enterprise maintaining more than just one data center can also apply a distributed data center comprehensive load management. This paper presents a vision minimizing the energy requirement or energy costs, using geographical specific characteristics of servers and data centers. The potential for savings of the introduced distributed load management can be up to 40%.
