Ceph Storage Cluster

The Ceph Storage Cluster, often referred to as the Reliable Autonomic Distributed Object Store or RADOS, stores data as objects within pools. In most cases, these objects are the atomic units representing client data, such as Ceph Block Device images, Ceph Object Gateway objects, or Ceph File System files. However, custom applications built on top of librados might bind to a pool and store data too.

Cephx controls access to the pools storing object data. However, Ceph Storage Cluster users are typically Ceph clients, and not users. Consequently, users generally DO NOT have the ability to write, read or delete objects directly in a Ceph Storage Cluster pool.
