Clonee will be packed full of cutting-edge technology, making it one of the most advanced, efficient and sustainable data centers in the world. All the racks, servers, and other components have been designed and built from scratch as part of the Open Compute Project, an industry-wide coalition of companies dedicated to creating energy- and cost-efficient infrastructure solutions and sharing them as open source.
It would be the second in Europe. The other one is in Lulea, Sweden, 2011.
