Ceph Storage Cluster APIs

The Ceph Storage Cluster has a messaging layer protocol that enablesclients to interact with a Ceph Monitor and a Ceph OSD Daemon.librados provides this functionality to Ceph Clients in the form ofa library. All Ceph Clients either use librados or the same functionalityencapsulated in librados to interact with the object store. For example,librbd and libcephfs leverage this functionality. You may uselibrados to interact with Ceph directly (e.g., an application that talks toCeph, your own interface to Ceph, etc.).
