Energy efficiency measurements of data center systems

The contribution of virtualising technology is without doubts. Frequently the defence of contribution of virtualization is ungrounded or with very weak argumentative support. UHK (University of Hradec Kralove) carried out a research to verify the validity of these facts. This paper presents a part of the research output. It particularly deals with approaches how to process expected decrease in electric power consumption also in cases of waste heat recuperation. Naturally, these results are partly dependant on regional circumstances (labour and energy prices), but their processing principles are evaluated generally enough to be applicable onto any national environment with functional market economy. The present research is grounded by a case study and is based on a demand to evaluate the contribution of virtualised technology development for a prominent provider of high-capacity personalised print SW solutions.
