There is no longer any need to build datacentres from the ground up, they can be manufactured in a factory and dropped directly into a site, according to global consultancy Capgemini.
The firm appears to have proof too, boldly claiming to have created the most sustainable datacentre in the world down in Swindon, where the climate is apparently optimal for the fresh-air cooling system it has implemented.
The Merlin datacentre was designed to be the most sustainable and efficient storage facility with the key goals being to reduce power, water and emissions, explained Paul Anderson, program director of outsourcing services at Capgemini UK.
Using the modularity approach, Capgemini has ensured that its datacentre is re-useable. The modules used to house data were originally designed as field hospitals and are fully mobile as well as being 95 per cent recyclable.
Power Usage Effectiveness (PUE) is the official measure used to determine how efficiently a datacentre uses its power. Ideally, all datacentres should have a PUE of one, meaning that the power running the IT should be equal to the power running the entire facility. However, in practice this is impossible.
The industry average is 2.6, with the best practice generally regarded as 1.3. Microsoft and Yahoo have achieved 1.2, while the one million square foot Google E facility touts a 1.12 rating.
Merlin has beaten them all, with a PUE rating of 1.1, according to Capgemini.
Anderson even acknowledged that PUE ratings can be manipulated to make a datacentres look efficient without taking into account the environmental damage that may be caused in generating a low PUE rating. Capgemini's Swindon facility is the most sustainable in the world based on all other aspects, not just the PUE, he said.
Capgemini's Merlin facility uses 50 per cent of the power and 30 per cent less water than traditional datacentres. For every 232KW of IT load being used in a module, 8KW of energy is used to cool it, according to Capgemini.
The Merlin centre will be certified as a Tier 3 data centre, making it only the third of this kind in Europe.
"Going green is viewed to be expensive. We wanted to prove that you could get a sustainably run datacentre at the lowest price to offer to clients out of the ones we have in the UK."
"Datacentres are eating power exponentially at the moment. The datacentre industry is not using as much carbon as the aviation industry yet but we're likely to go above them when cloud computing takes off as it is far more energy intensive."
Anderson stated that in the future, the modules could be taken to the clients and stored at their sites. This could be perfect for a number of organisations such as the MOD, which has it own secure facilities and other organisations that can re-use old buildings to store their data in.
Future datacentres will probably require their own power generators to be built next to them because the National Grid will not be able to cope with demand, according to Capgemini and the firm is already looking at a number of options including biofuel.
