Protecting PV system components, in particular inverters, from the damaging effects of overvoltage surges is both crucial and necessary. Here Tony Garlinge-Warren, senior applications engineer, Eaton’s Bussmann business, examines what measures should be considered

When specifying LED light sources for exterior lighting applications, there are a number of new factors to consider, compared to more traditional light sources. Terry Dean of DW Windsor explains

What are the current trends in regard to cases and subracks? If we take a closer look at what is currently happening in this area, one word comes up again and again: individuality. This relates to the functionality, construction, dimensions, appearance and also to accompanying service options. Martin Traut, product manager for subracks and cases at Pentair - Schroff GmbH, and David Martin, managing director at Pentair - Schroff UK, explain

After all the discussion of the last few years concerning PUE and how to reduce it, are we perhaps becoming a little jaded with ‘green’? For most of us, day-to-day customer service has to be our main priority. If we can maintain uptime, our clients are happy – and so are we. But lofty aspirations on energy efficiency can comfortably dovetail with uptime targets, writes Andy Mullings, data centre business development manager at Synapsys, since clear and accurate information from your power monitoring system can quite naturally contribute to an improved PUE

415 Research says prefabrication is about to transform the data centre world. Matthew Baynes, enterprise sales director at Schneider Electric agrees wholeheartedly

After a prolonged infancy, prefabricated modular (PFM) data centres are now rapidly evolving and gaining mainstream market support, says 451 Research, a global analyst with established credentials in the sector. Factors which will serve to facilitate this transformation include the number of credible products and suppliers, the fact that solutions are becoming available for most applications, and some high profile case studies.

At PowerOn 2013, Leo Craig, general manager of Riello UPS explored the importance of energy efficiency in data centres but stressed the crucial balance to be achieved between energy efficiency and resiliency in order to achieve the optimum data centre environment

Despite an uncertain outlook for our energy future data centres across the country are consuming more and more power from the grid but do they have a corporate social responsibility to get smarter about their energy management?  Leo Craig, general manager at Riello UPS, discusses the issues facing data centres in a changing energy landscape and explores what measures they can take to reduce energy consumption while still maintaining the optimum level of resiliency and reliability

Data centre infrastructure management (DCIM) systems collect and manage data about a data centre’s assets, resource use and operational status throughout the data centre lifecycle. This information is then distributed, integrated, analysed and applied in ways that help managers meet business and service-oriented goals and optimise the data centre’s performance. At PowerOn 2013 Amit Singala, software business development manager at on365 – an elite partner of Schneider Electric, presented an introduction to some of the benefits of DCIM

According to IT research company, Gartner, 2% of the world's carbon emissions are produced by data centres and are expected to exceed those of the airline industry by 2020. It's no surprise therefore that there is an increasing drive towards achieving 'green' data centres, with operators assessing their power usage effectiveness (PUE) efficiency levels continually, through analysing both their power and cooling demands

Unpredictable data growth and equally hard-to-predict performance demands from users mean that data centre operators are increasingly turning to converged infrastructure to provide them with the flexibility they now need. If converged infrastructure is to achieve its full potential, however, careful attention must be given to the way it’s powered – traditional power architectures are rarely the best solution. We interviewed Tatu Valjakka, software and connectivity product manager for Eaton’s EMEA power quality business, to find out more

The pace of change throughout the IT industry continues to accelerate, and data centres are no exception. Artur Faust, product manager 3-phase UPS, Data and IT Solutions at AEG Power Solutions, explains

Rapidly evolving business cases require IT to align with updated priorities in the short term – whether that is cloud computing, virtualization, social media or hybrid IT. Data centres must be flexible, and must be able to respond to change in only a few weeks rather than many months. System utilisation can vary significantly at a moment's notice, and systems must cope.

What is the right way to cost effectively cool a data centre? Is it about increasing the input temperature? Maybe aisle containment is the answer? What about free air cooling? Should high density racks be water cooled? All of these are questions that data centre owners should be reviewing on a regular basis when looking at their data centre. Those failing to review their cooling could be playing Russian roulette with their facility. Mark Hirst of Cannon Technologies looks at what can happen
