back to article CERN swells storage space beyond 1EB for LHC's latest ion-whacking experiments

In preparation for its latest round of ion-smashing tests, CERN boosted its storage array for the experiments to more than one million terabytes in total size. The facility's data store now exceeds an exabyte of raw capacity — with much of it on hard disk drives and an "increasing fraction of flash drives," the European super- …

    A department at our place works with data from the LHC. I can see them asking for more bandwidth and storage.

    *sigh*

      Has anyone, anywhere, ever asked for less bandwidth and storage?

    Flashback!

    Once upon a time 1 TB was an awesome amount of storage.

    You had to have your own data center to even think about it

      I remember an event about 30 years ago, where our “computer room” reached 1 TB of storage. We had champagne and caterers in for the event.

      Pint icon, cause we had a load of them.

    Brand (s) ?

    I'm fasicnated.

    What brand(s) of storage are they using?

    Are they SAN arrays, object-oriented?

    What kind of file systems?

    And what kind of data protection - RAID, replication or something more exotic?

    With that much disk space...

    ... they'll able to install the latest windows update.

      It'll get to its second reboot and then decide to run chkdsk.

    Stats ... for science

    Does CERN publish stats regarding disk life, fault rates, etc. along the lines that rackspace and possibly other storage providers do?

    With a 5-digit number of disks in use, they may produce some nice statistics.

    It will be fun trying to run windirstat or duc or other tools like that to visualize the disk usage, much less keep it upto date.
