CERN and the other colliders around the world spit out a LOT of data. When I went to see one a few years ago at Rutherford Appleton (sp?) I remember them saying that they produce so much data it is all kept in volatile ram and then someone has to make a call quickly as to whether it is valuable enough to dump to disk before it is lost.
When I worked as a SAN support guy I could only dream of looking after EVAs. Ever heard of HSG80s? Neither had most of the HP engineers I met*
*To be fair most of the engineers were pretty good, it was always the people back at base who could never find the parts. Don't get me started on EMC. Rudest bunch of people I ever had the displeasure of meeting, on the whole.
