CERN generates one petabyte per second

Posted on Monday, June 27 2011 @ 22:21:45 CEST by

V3 reports experiments at CERN generate roughly one petabyte of data every second! Not all the data is stored though, Francois Briard, control infrastructure section leader, explains only the few pieces that are of interest are stored. This data of the rare events that occur during particle collisions totals about 25 petabytes per year.
However, Francois Briard, control infrastructure section leader, beam department, explained that CERN doesn’t capture and save all of this data, instead using filters to save only the results of the collisions that are of interest to scientist at the facility.

“We don’t store all the data as that would be impractical. Instead, from the collisions we run, we only keep the few pieces that are of interest, the rare events that occur, which our filters spot and send on over the network,” he said.

This still means CERN is storing 25PB of data every year – the same as 1,000 years' worth of DVD quality video – which can then be analysed and interrogated by scientists looking for clues to the structure and make-up of the universe.
