High Power Density Colocation Service for CERN

High Power Density Colocation Service for CERN

CERN extends its data center into Safehost’s facility to meet demand for critical power.


  • Provide a high power density colocation environment
  • Create cooling efficiencies during the design phase
  • Balanced power distribution across phases


  • An optimal power & cooling design
  • Dedicated SafeSuite™ data centre collocation service
  • High-density redundant power service
  • 24×7 monitoring portal for live power & environmental parameters


  • Capacity to continue to extend CERN’s critical power footprint outside of its premises
  • Effective capacity management through real-time monitoring of racks

“… they offered us meaningful service level agreements for power and temperature and the ability to track power and cooling metrics in real-time.”


CERN turned to Safehost when it needed to find a secure and reliable data centre facility, one with the capacity that met its ever-expanding data storage requirements and its demand for critical power.

One of CERN’s largest projects, the Large Hadron Collider (LHC), studies particles and the forces that bind them together. This is done by firing protons round a 27 km circuit that exists 150 m below ground. 1,000 bundles of 100 billion protons are fired by each beam, whose direction is curved around the circuit by supercooled (-271°C) super-conducting magnets, and is made to collide at the centre of four detectors.

The resulting interactions between the protons are measured millions of times per second. To sort the data down to a few hundred ‘good’ events per second they rely on computers, but even this generates between 100 and 1,000 megabytes of data each second. The result is that CERN’s scientists manage more than 15 petabytes of new data each year.


Working closely with CERN’s data centre engineers, Safehost designed an optimised layout for power and cooling. The installation was completed within budget. The solution involved configuring and installing dedicated power boards in a redundant configuration, fully-integrated into Safehost’s building alert system.

This gives CERN the ability to monitor its power-loading across each phase in real-time, allowing a clear picture of their capacity usage.


The successful outcome of the project is proof-positive that outsourcing the data centre is a viable option for CERN. Safe Host provides an ideal secure environment for the continued growth in data expected over the coming years.

“Safehost was able to meet the service and environmental needs of CERN comfortably, including the provision of a highdensity power supply (…) they offered us meaningful service level agreements for power and temperature and the ability to track power and cooling metrics in real-time”.

About CERN

The European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research.

Its business is fundamental physics, finding out what the Universe is made of and how it works. At CERN, the world’s largest and most complex scientific instruments are used to study the basic constituents of matter — the fundamental particles. By studying what happens when these particles collide, physicists learn about the laws of Nature.

Founded in 1954, the CERN Laboratory straddles the Franco–Swiss border near Geneva. It was one of Europe’s first joint ventures and now has 20 Member States.
