A fraction of the 111 000 devices that form CERNs data storage capacity.

CERN’s data store not only serves LHC physics data, but also the whole spectrum of experiments and services needing online data management.

The European Organization for Nuclear Research (CERN) in Switzerland has exceeded the 1-exabyte threshold, amassing 1 million terabytes (TB) of disk space.

A total of 111,000 devices, mostly hard drives and a growing number of flash drives, provide this data capacity.

CERN's Andreas Peters said, "We reached this new all-time record for CERN's storage infrastructure after capacity extensions for the upcoming LHC [Large Hadron Collider] heavy-ion run," with the combined data store's reading rate passing the 1 TB/second mark.

This achievement "sets new standards for high-performance storage systems in scientific research for future LHC runs," added CERN's Joachim Mnich.
