Open Source Summit Europe + ELC Europe 2017

Ceph is an open source distributed object store, network block device, and file system designed for reliability, performance, and scalability. With an advanced placement algorithm, active storage nodes, and peer-to-peer gossip protocols, Ceph is software-defined storage for scaling from terabytes to exabytes with no single point of failure. Powerful features like instantaneous snapshotting and copy-on-write clones, along with self-management and automatic healing, make Ceph friendly to administrators and users. This talk introduces the Ceph architecture and features in the latest upstream Luminous release, focusing on enhancements to the RADOS Block Device and CephFS distributed filesystem — including new horizontal metadata scaling.
