CERN’s mission is to learn more about how the universe works. Home to the world-renowned Large Hadron Collider (LHC), CERN is advancing the boundaries of human knowledge through breakthrough research in fundamental physics. CERN chose Juniper Networks for powerful, high-density switching that is ready to help unlock the mysteries of the universe.
The LHC experiments are designed to observe up to 1.7 billion proton-proton collisions per second and produce a data volume of more than 7.5 terabytes per second. Only some of these events lead to new discoveries, therefore the flow of data is filtered and reduced to a manageable level. The LHC experiments’ Trigger and Data Acquisition Systems handle data filtering, collection and infrastructure monitoring. Juniper’s switching portfolio provides high-throughput connectivity to support the data collection and infrastructure monitoring.
CERN’s Geneva data center supports all of its scientific projects, experiments and administrative systems, from spotting camera-shy pentaquarks and charm mesons to everyday video conferencing and payroll tasks. The data center network supports more than 15,000 servers and 260,000 processor cores. It enables researchers around the world to receive data from the LHC experiments for analysis. In the last 12 months, 370 petabytes of data have moved across the network.
·To prepare its data centers for the next wave of scientific discovery, CERN deployed Juniper’s QFX10008 Ethernet Switch for the new data center core network. The QFX10008 switch delivered on CERN’s requirements for fast, reliable connectivity and 100-Gbps port density to support the inevitable traffic growth. The core network can be scaled from 40 Gbps to 100 Gbps.
·The QFX Switch provides high-throughput connectivity to support the data collection and infrastructure monitoring of the LHC experiments. Multiple virtual router instances with different class-of-service policies allow different traffic types, such as management, control, data, monitoring and simulation, enhancing redundancy, load balancing and increased network efficiency.
·Juniper’s EX9200 Ethernet Switch, connecting 11,000 devices, supports the LHC operations and experiments, as well as monitoring and safety systems. The architecture enables a robust, reliable and scalable technical network.
Automation has simplified the configuration and management of 400 routers and switches across CERN’s campus. Open source plays a vital role in meeting the research demands from collaborators around the world.
