CernVM-FS Operations in the CERN IT Storage Group


Dan van der Ster (CERN)


This talk will present the status and plans of the CERN IT's CVMFS Operations Service, recently reassigned to our IT Storage Group. The first part of the talk will outline the architecture of the stratum zero, CERN stratum one, local squids; the notable feature of our service is that during 2015 is has been (almost) entirely moved to CERN's OpenStack infrastructure, making extensive use of Ceph and ZFS which has proven to be quite flexible while also offering a disaster recovery solution.

The second part of the talk will look to the future. CERN IT's recent change of strategy with respect to OpenAFS will put increased demands on CVMFS. We'll outline some of these new use-cases which are forthcoming for CVMFS, then present alternatives for the future scale-up and out of the system.
