THE FUTURE OF STORAGE™

Ceph is a unified, distributed storage system designed for excellent performance, reliability and scalability.

GET INVOLVED

Anyone can contribute to Ceph, and not just by writing lines of code!

FACE-TO-FACE

There are tons of places to come talk to us face-to-face. Come join us for Ceph Days, Conferences, Cephalocon, or others!

Object storage

Ceph provides seamless access to objects using native language bindings or radosgw (RGW), a REST interface that’s compatible with applications written for S3 and Swift.

Block storage

Ceph’s RADOS Block Device (RBD) provides access to block device images that are striped and replicated across the entire storage cluster.

File system

Ceph provides a POSIX-compliant network file system (CephFS) that aims for high performance, large data storage, and maximum compatibility with legacy applications.

This has the potential to dramatically reduce the overall cost per terabyte of Ceph systems since the usual 3x storage overhead of replication can be...
