The CERN Data Centre is the heart of CERN’s entire scientific, administrative, and computing infrastructure. All services, including email, scientific data management and videoconferencing use equipment based here. A remote extension of the CERN Data Centre is hosted at the Wigner Research Centre for Physics in Hungary to provide the extra computing power required to cover CERN’s increasing needs.
The 230 000 processor cores and 15 000 servers run 24/7.
Over 90% of the resources for computing in the Data Centre are provided through a private cloud based on OpenStack, an open-source project to deliver a massively scalable cloud operating system.
