 Ceph is a massively scalable, open-source, distributed
 storage system that runs on commodity hardware and delivers object,
 block and file system storage.
 .
 Crimson is a re-implementation of the ceph-osd daemon using a more
 platform aware and scalable software architecture (seastar).
 .
 This package contains the Crimson Object Storage Daemon for the
 Ceph storage system. It is responsible for storing objects on a
 local file system and providing access to them over the network.
