Inside Cern's atom-smasher number-cruncher

The LHC will produce around 15PB (petabytes) of useable data per year. The computer centre will only be able to process approximately 20 percent of the data produced, according to Cern's head of network services, Jean-Michel Jouanigot (pictured centre). The rest of the data will be processed by the LHC computing grid, a conglomerate of systems in 140 institutions in 33 countries.
