About
There is significant diversity in the Data Acquisition (DAQ) systems of the non-LHC experiments supported at CERN. Each system can potentially have its own data taking software and helper scripts, and each can use their preferred data transfer commands and apply different checks and retry policies. The task of the CERN Tape Archive (CTA) team is to provide support for all of these different use cases and to define the best practices for integrating with an EOSCTA instance.
In this talk we will present an overview of typical DAQ workflows and discuss which protocols, commands and APIs we recommended to use with EOSCTA. We will provide examples of submitting archive and retrieve requests using FTS and XRootD tools. We will explain how to monitor the status of a file on tape. We will explain the best way to ensure a file is safely stored on tape. We will also give an overview of the CTA authentication policies..
