The CERN Tape Archive (CTA) is the archival storage system for the custodial copy of all physics data at CERN. CTA is implemented as the tape back-end to EOS. EOS+CTA is the CERN archival solution for LHC Run–3 and beyond.

For a general overview of CTA, see our Publications and Presentations. There is also some general Development and Systems Integration Documentation which complements what is on this site.

Just a note to myself since I searched the internet for a long time to make this work…

I needed to test a really trivial change to the scsi tape driver code, but didn’t want to reboot an actual machine that has a tape drive. So I thought, maybe QEMU can pass-through an arbitrary device?
