Datacentres have begun to rule the world — vast, secure, climate-controlled IT palaces that provide the backbone of our working lives.
This round-up of datacentres from around the world gives an insight into the powerful technology that toils behind the scenes to keep the modern world turning.
Capgemini's Merlin datacentre
Capgemini's Merlin datacentre (above) is housed within an old 86,000-square-foot warehouse in Swindon, UK. It has a total datacentre area of 10,000 square feet, and a power usage effectiveness (PUE) rating of 1.1.
PUE expresses the proportion of power that must be expended to support the IT infrastructure, versus the power that actually runs the racks, servers, network equipment and other essential components of the datacentre. A PUE rating of 1.1 means that only 10 percent of the total facility's power goes on the support infrastructure, with the rest going on the equipment. A PUE of 1.1, therefore, is pretty impressive — and it makes Capgemini's centre one of the most efficient in this collection.
