- 3. Ceph What is it?
- 4. The project ➜ Unified distributed storage system ➜ Started in 2006 as a PhD by Sage Weil ➜ Open source under LGPL license ➜ Written in C++ ➜ Build the future of storage on commodity hardware
- 5. Key features ➜ Self managing/healing ➜ Self balancing ➜ Painless scaling ➜ Data placement with CRUSH
- 6. Controlled replica9on under scalable hashing ➜ Pseudo-random placement algorithm ➜ Statistically uniform distribution ➜ Rule-based configuration
- 7. Overview
- 8. State of the integra9on Including best Havana’s addi9ons
- 9. Why is Ceph so good? It unifies OpenStack components
- 10. Havana’s addi9ons ➜ Complete refactor of the Cinder driver: • Librados and librbd usage • Flatten volumes created from snapshots • Clone depth ➜ Cinder backup with a Ceph backend: • • • • • backing up within the same Ceph pool (not recommended) backing up between different Ceph pools backing up between different Ceph clusters Support RBD stripes Differentials ➜ Nova Libvirt_image_type = rbd • Directly boot all the VMs in Ceph • Volume QoS
- 12. Is Havana the perfect stack? …
- 13. Well, almost…
- 14. What’s missing? ➜ Direct URL download for Nova • Already on the pipe, probably for 2013.2.1 ➜ Nova’s snapshots integration • Ceph snapshot https://github.com/jdurgin/nova/commits/havana-ephemeral-rbd
