Storage Business Continuity and Disaster Recovery with Ceph and OpenStack
The Storage Group at CERN (European Organization for Nuclear Research) operates several Ceph clusters providing block, file, and object storage, totaling more than 100 PB of raw capacity. Ceph is a critical component of the IT infrastructure and it provides, together with the OpenStack compute cloud, CERN users with central IT services and a large-scale computing and storage infrastructure for scientific data analysis. The storage infrastructure is being rationalized and restructured to offer solutions in the context of Business Continuity and Disaster Recovery. In this presentation, we report on RBD snapshots and mirroring improvements, on how CephFS Manila shares are backed up to S3 (and in the future to tape) via a restic-based backup orchestrator, and on the instantiation of storage services spanning different computing centers.
