redundancy. The second container, PowerShelter, then contains all the necessary switchgear and a backup generator. ‘We size DataShelter units in kilowatts per rack
(for UPS and cooling) and the lowest in the range is around two to three kW with only one or two servers running per rack. However, DataShelter can go up to 20 to 25 kW per rack and our engineers are working on a solution to get it up to 50 kW per rack,’ says Pearce. ‘We have worked with several different clients over the past six months and each package has been completely different from the others. Variants depend on where they need to go in the world, which can impact the required kW per rack, operating temperature range, internal layout and whether they require servicing.’
Smart choice With the National Grid struggling to meet current demand, this is the ideal opportunity for data centres to consider smart grid technology and on-site power generation as an alternative to reliance on traditional grid supply, thinks Riello’s Leo Craig. ‘Energy efficiency, cost-savings and demand-response payments from the suppliers themselves are just some of the incentives for large power consumers, such as data centres, to move away from complete dependence on the grid. Embracing new technology such as Super-Caps, DC flywheels and lithium-ion batteries as forms of energy storage, combined with UPS, generators and solar panels, will make data centres of the future efficient, resilient and environmentally sound.’
It is essential to provide UPS solutions that maximise efficiency
costing less than £600 a year. ‘Over a five year period, we will be saving almost £39,000 in reduced energy and air conditioning costs alone,’ says Winser. ‘The new UPS system was
also able to deliver a 37 tonne CO2 reduction, due to the UPS being 11 per cent more efficient at its expected loading.’ West Sussex County Council was also
able to receive 80 per cent of the total purchase and installation costs through the Salix Finance scheme, funded by the Department of Energy and Climate Change (DECC). Salix Finance helps to empower public sector organisations to take a lead in tackling climate change by helping to increase their energy efficiency. Commercial organisations could also benefit from the PowerWAVE 9000DPA’s high efficiency and low cost of ownership through its inclusion on the Carbon Trust’s Energy Technology List for enhanced Capital Allowances.
