Capgemini, one of the world’s foremost providers of consulting, technology and outsourcing services, today announced the opening of a new state-of-the-art sustainable data centre in the UK, poised to set new standards for global data centre energy efficiency through its industry-leading energy ratings and modular design. Amid growing demand for outsourcing and cloud services, Capgemini designed the new data centre from first principles, applying smart engineering thinking to rethink the entire blueprint. Clients who outsource their IT or business processes, or use Capgemini’s cloud offerings will benefit from cost savings and environmental ratings but also a high level of quality and technical service.

The new “Merlin” data centre – built on a brown field site in Swindon, UK – boasts a low power usage effectiveness (PUE) annualised rating of 1.08 (factory tested): a worldwide industry first. As well as featuring a smart modular design, the facility guarantees a high level of energy efficiency through its use of fresh air cooling. The data centre was built using eco-considerate materials and sustainable sourcing was encouraged at all points of the build. The electricity consumption of the facility will be just half that of a traditional facility, while maintenance costs will only be a quarter of that of older designs.

The new UK facility is a key component of Capgemini’s Global Infrastructure Outsourcing (GIO) strategy which has invested €100million across a global data centre portfolio of 25 facilities in Canada, China, Finland, France, Germany, the Netherlands, Spain, Switzerland and the United States, as well as the UK. Capgemini’s GIO supports over 26,000 physical servers of which 8,000 are virtualised1. Capgemini’s key focus is on data centre optimisation to respond to client’s demands for security, sustainability and cost efficiency. Merlin is designed to support the full continuum of managed services from legacy and dedicated client infrastructures through to utility and Capgemini’s latest cloud based services.

With global demand for our outsourcing and cloud services growing sharply, we needed more space to house such services” says Capgemini’s CEO of Global Infrastructure Management, Richard Dicketts. “However, we had to develop new facilities that could support the efficiencies our clients seek. Meeting the requirements of 21st century businesses in terms of agility, cost and risk management, fully managed, virtualised and private cloud services need to be delivered alongside the more traditional data centre services. The Merlin facility represents a new generation of data centre design, which redefines industry standards and has resulted from both our long term drive to improve efficiency and the contractual imperatives to deliver environmental efficiency. Using this blueprint we will be able to set up large or small facilities wherever they are needed around the globe to fulfil demand for services.”

Key features of the “Merlin” data centre

  • Output: Merlin has a power usage effectiveness (PUE) rating of 1.08 (factory tested)2. Whilst PUE ratings are improving steadily, the industry standard remains between 2.0 and 2.5. The Merlin facility represents a step-change in addressing this industry challenge.
  • Fresh air cooling system: Each module is equipped with a highly dedicated Air Optimiser climate control cooling unit which step-cools air in stages, with primary “fresh air” cooling and second stage evaporative cooling.
  • BMS and climate control: The bespoke building management system is one of the most sophisticated ever designed by Capgemini. Fully managed hot and cold air flows enable constant peak operational efficiency.
  • Certified Tier 3: Merlin will be certified as an Uptime Institute certified Tier 3 data centre3, one of only three such sites in the UK.
  • 60,000 square foot technical floor capacity: The data centre of over 100,000 square feet has the ability to supply 60,000 square feet of available technical floor space, comprising 24 x 2,500 squarefoot modules.

[1] Virtualisation: this service converts hardware such as servers, networks, storage and even desktops into virtual environments. This radically improves utilisation, speed of deployment and provisioning, and enables new support models. Virtualisation appeals to any organisation looking to improve its capacity whilst avoiding further capital expenditure.

[3] Uptime Institute is a think tank which was founded by a number of datacentre specialists (from management, design and datacentre construction companies). This organisation is most well-known for having introduced its datacenter rating system, which classifies datacentres according to their resilience (Tier 1 to 4).
