   <title>Add the Block Storage service</title>
   <para>The OpenStack Block Storage service provides block storage devices
-    to instances using various backends. The Block Storage API and scheduler
-    services run on the controller node and the volume service runs on one
-    or more storage nodes. Storage nodes provide volumes to instances using
-    local block storage devices or SAN/NAS backends with the appropriate
-    drivers. For more information, see the

+    to guest instances. The method in which the storage is provisioned and
+    consumed is determined by the Block Storage driver, or drivers
+    in the case of a multi-backend configuration. There are a variety of
+    drivers that are available: NAS/SAN, NFS, iSCSI, Ceph, and more.
+    The Block Storage API and scheduler services typically run on the controller
+    nodes. Depending upon the drivers used, the volume service can run
+    on controllers, compute nodes, or standalone storage nodes.

     <para>This chapter omits the backup manager because it depends on the
