that is compatible with a large subset of the OpenStack Swift API.
Ceph Object Storage uses the Ceph Object Gateway daemon (``radosgw``), an HTTP
-server designed for interacting with a Ceph Storage Cluster. The Ceph Object
+server designed to interact with a Ceph Storage Cluster. The Ceph Object
Gateway provides interfaces that are compatible with both Amazon S3 and
OpenStack Swift, and it has its own user management. Ceph Object Gateway can
-store data in the same Ceph Storage Cluster in which data from Ceph File System
-clients and Ceph Block Device clients is stored. The S3 API and the Swift API
-share a common namespace, which makes it possible to write data to a Ceph
-Storage Cluster with one API and then retrieve that data with the other API.
