Those technologies which indicate the greatest increase in interest into 2009 among Western European datacenter owners and operators include moving the primary datacenter(s) out of central City areas, blades and higher density servers, direct current power solutions and building to meet regulatory and accreditation requirements. Note that these figures are indices comparing 2007-8 consideration with 2008-9 figures.

A number of the upcoming technologies are specifically associated with energy efficiency indicating the strong growth this has assumed as a criterion for selecting solutions and technologies. The continuing presence of higher density servers on the list indicates the balance that needs to be achieved between efficiency of consumption and efficiency of performance.
