    I’m a little confused by this submission. CASTOR is the old system that has since been replaced by the CERN Tape Array since ~2020: https://cta.web.cern.ch/cta/

    This is mentioned on the page but it’s easy to miss.

    For the current status of tape storage at CERN see: https://indico.cern.ch/event/1471803/contributions/6967379/a...

    For reference, most disk storage for physics data uses an in-house solution called EOS: https://eos-web.web.cern.ch/eos-web/

    This is actually super useful for real world stuff. Thanks for this.

    Tape is boring but when an intern / AI / tectonic plate accidently destroys your database setup it is a huge lifesaver

    Anybody know what these fancy Oracle tapes are? Is it just their implementation of a regular standard?

    "Castor" was the name of a storage system used for transporting nuclear waste in Germany. There were quite a few protests against shipping nuclear waste through the country.

    Wouldn't have been my choice for a software project :-)

      It’s also French for Beaver which is more likely the origin of the name.

        It's also Latin and Greek for beaver which is more likely the origin of the name.

    looks like the image on the right is broken, but it is supposed to be: https://cta.web.cern.ch/cta/assets/images/namespace_statisti...

    (looks like this submission uses https://castor.web.cern.ch/content/home.html instead of https://castor.web.cern.ch/castor/ the second link does not have the broken image)

    The various CERN web pages such as this were a treasure trove of information when I was working on my last novel. I actually included a few paragraphs on Castor thinking of using it as a side-plot, but my editor cut the plot out along with a few other technical niceties. Sigh!
