The CERN Tape Archive (CTA) is the tape back-end to EOS. Configuring EOS to work with CTA allows event-based triggering of tape archivals and retrievals. As well as controlling the tape hardware (libraries and drives), CTA provides an advanced queue manager and scheduler to manage how and when tapes will be mounted, to optimise the use of the tape infrastructure. This presentation will provide an overview of CTA's features and how they integrate with EOS. There will be a separate hands-on session on Day 3 to learn how to configure EOS+CTA.
