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 CASTOR is the old system that has since been replaced by the CERN Tape Array since ~2020: https://cta.web.cern.ch/cta/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.
Does tape array replace castor? Just from the names it sounds like tape array is the actual storage, and castor is an abstraction that automatically decides what's kept on disk and what's kept on tape
"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 :-)
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!

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/
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?
There isn’t a recording but slides at linked from that page.
