+                OSD BlueStore is a storage back end used by OSD daemons, and
+                was designed specifically for use with Ceph. BlueStore was
+                introduced in the Ceph Kraken release. In the Ceph Luminous
+                release, BlueStore became Ceph's default storage back end,
+                supplanting FileStore. Unlike :term:`filestore`, BlueStore
+                stores objects directly on Ceph block devices without any file
+                system interface. Since Luminous (12.2), BlueStore has been
+                Ceph's default and recommended storage back end.
