+       **One Object Storage:** The Ceph Object Store, called RADOS, is the 
+       object storage component for CephFS filesystems, Ceph RADOS Gateways, and 
+       Ceph Block Devices.
+       
+       **Many Storage Interfaces:** You can use CephFS, Ceph RADOS Gateway, or Ceph 
+       Block Devices in your deployment. You may also use all three interfaces 
+       with the same Ceph Object Store cluster! There's no reason to build three 
+       different storage clusters for three different types of storage interface!
+       
+       **Use Commodity Hardware!:** You can deploy Ceph with commodity hardware. 
+       You don't need to purchase proprietary storage or networking hardware 
+       commonly used in :abbr:`SAN (Storage Area Network)` systems.
