Ceph

Ceph is a massively scalable, open source, distributed storage system. It is comprised of an object store, block store, and a POSIX-compatible distributed file system. The platform is capable of auto-scaling beyond the exabyte level, it runs on commodity hardware, it is self-healing and self-managing, and has no single point of failure. Ceph is in the Linux kernel and is currently being integrated with the OpenStack™ cloud operating system. DreamHost is the principal sponsor of the open source Ceph project. As a result of its open source nature, this portable storage platform may be installed and used in public or private clouds.
