Impact of cabling choices on data centre sustainability: Lee Funnell speaks at Data Centre Alliance Conference

The central role played by network cabling in the overall efficiency and performance of the data centre was a key topic at the Data Centre Alliance's international conference on 'Sustainable Data Centre Design and Operation', held at the School of Mechanical Engineering at the University of Leeds.

On the first day Lee Funnell CTP spoke on behalf of infrastructure expert Siemon and delivered a paper entitled "Critical architecture choices and the dramatic impact of the physical layer on data centre performance". In his session Funnell explained the significant effects that the choice of Layer 1 architecture can have on both power and cooling. A range of physical layer systems for the data centre were discussed and their impact evaluated in terms of energy efficiency within the context of total performance.

Delivering a thought provoking talk on an often overlooked physical aspect of data centre provision, Funnell discussed the arguments surrounding the use of any-to-all, versus top-of-rack and end-of-row patching. He gave guidance on the medium and long-term implications of these (and other architecture variant) choices, plus prompted discussion on the implications for modularity and flexibility.

Data centres now contribute roughly 25 per cent of the world's total IT CO2 emissions, according to the Data Centre Alliance (DCA) and this is described as growing rapidly, presenting governments and companies with an energy supply problem. As the independent not-for-profit organisation, run by and for the data centre industry, the DCA has a critical role to play in prompting proactive consideration of sustainable approaches to data centre provision and operation.

The first Data Centre Alliance conference sought to provide data centre professionals with reliable, independent information and expert advice, delivered by the leading experts in the industry. With a multi-disciplinary scope, this included infrastructure, site selection, investment planning and cost analysis, project management and capacity management.

In association with the DCA, the University of Leeds hosted the two day conference on June 21 and 22, 2011. Papers were delivered on all aspects of data centre design and operation, with a particular emphasis on energy efficiency and sustainability.
