 RAIDStorage and back-ends with a single shared file system
 ----------------------------------------------------------
 
-- blob-dir configured to a directory shared between raidstorage,
-  clientstorages and back-end servers (read/write for all participants)
+The blob directories of RAIDStorage and ClientStorages (on the RAID server)
+are configured with a single shared directory that is readable and writable by all
+participants.
 
-- shared-blob-dir for raidstorage and clientstorages set to `true`
+The `shared-blob-dir` option of the RAIDStorage and the ClientStorages are set
+to `true`.
 
 
 RAIDStorage via storage API and back-ends with individual shared file systems
 -----------------------------------------------------------------------------
 
-- RAIDStorage and ClientStorages have separate blob directories
+The RAIDStorage and all ClientStorages have separate blob directories.
 
-- each ClientStorage shares its blob directory with its ZEO server
+The RAIDStorages `shared-blob-dir` option is set to `false`.
 
-- RAIDStorage has shared-blob-dir set to false
+Each ClientStorage's blob directory is shared with its ZEO server and their
+`shared-blob-dir` options are set to `true`.

 RAIDStorage via storage API and back end via ZEO protocol
 ---------------------------------------------------------
 
-- blob-dir configured to separate directories in raidstorage, clientstorages
-  and back-end servers
+All storages (RAIDStorage, ClientStorages and the ZEO server side) have
+separate blob directories.
 
-- shared-blob-dir for raidstorage and clientstorages set to `false`
+The RAIDStorage's and ClientStorages' `shared-blob-dir` options are set to

 Invalid back end configurations
 ===============================
 
 Mixture of shared and non-shared
 --------------------------------
 
-- The raidstorage having a shared directory with the zeo clients but the zeo
-  clients not sharing with the back end servers is unsupported.
+Variation A: The RAIDStorage shares its blob directory with its
+ClientStorages, but the ZEOClient do not share their blob-directory with the
+backend ZEO servers.
 
-- The raidstorage using the storage API against zeo clients which share their
-  blob directory is unsupported.
+Variation B: The RAIDStorage does not share it's blob directory with its
+ClientStorages but the ClientStorages share their blob directory with the
+backend ZEO servers.
 
 Warning: ZEORaid can not automatically detect those invalid combinations and
-might destroy data if those are configured.
-
+might cause data loss if those combinations are configured.
