Security and efficiency without compromise Data centres can achieve far higher
levels of energy efficiency without compromising their security, writes Mark Trolley and John Inman of Borri Ltd, a leading supplier of Uninterruptible Power Systems (UPS) to the industry.
F
uelled by ever greater demand for more computing power in less space, the evolution of data centres continues at a pace. Over the last few years Borri has witnessed some big technology changes including the birth of supercomputing, virtualisation, server compaction and ‘cloud computing’.
However, a spiralling rise in electricity costs is driving data centres to monitor even more closely their power consumption, which is now influencing the design of new data centres and also the refocusing of existing facilities around technology efficiencies. Additional emphasis on power consumption has also been added through the introduction of the CRC scheme and the threat by government to publish “name and shame’ league tables.
Traditionally operators have concentrated their resources on reducing power usage by re-designing the mechanical layers of data centres through removing or reducing the traditional power hungry CRAC (Computer Room Air Conditioning) units. However, with many data centres now achieving an annualised power usage effectiveness of 1.5 to 1.2, the scope for any further savings is limited. Shrewd operators are therefore turning their attention to the computing and electrical infrastructure layers of the business. However, as Moores Law vividly illustrates, the efficiency gains made in terms of reduced computer power consumption will often be swallowed up by the power needs of increased processing power.
At Borri we also believe that the electrical layer presents the greatest opportunity to further increase the efficiency of all data centres and
