Data centre design trends in a power hungry world


When UPS was first introduced to the market, energy efficiency didn’t matter as much as it does now. What did matter was making sure connected loads were protected against the common power problems associated with raw mains energy – for example, voltage spikes, reductions in input voltage and blackouts. UPS systems have evolved greatly over the past decade, and it’s an evolution that has been driven by the rise of the data centre, in which the need to use power more effectively and to control lifetime costs of equipment is as important as the need for mission-critical power protection. By Leo Craig, general manager at Riello UPS Ltd.


IN THE MODERN DATA CENTRE, space is now a key consideration because of greater demands on infrastructure through the explosion of cloud-based services.


From this, a trend for higher power density is clearly emerging which ultimately means being able to pack more capacity into a smaller space. But with this trend comes a number of challenges as squeezing more

resources into a smaller area requires improved cooling facilities. It also needs the appropriate power distribution and backup infrastructure to support it.


With floor space a premium concern, managers must think carefully about how the data centre is designed, particularly with regard to future expansion plans. At the outset of any data centre design and build


project, it is prudent to fall back to the 5Ps adage of ‘perfect planning prevents poor performance.’


Changing times for data centre design


Most data centres will have an 18 month rolling expansion plan but this can be as little as three months for rapidly expanding cloud- based service providers. The expansion
