-SDL does not currently have any intelligent logic (e.g. dynamic scaling) on
-which storage node each namespace data is stored. This area might be developed
-further in the future.
+SDL supports also Redis sentinel based DB cluster where deployment has one or
+more DBAAS Redis sentinel group. Different DBAAS Redis sentinel groups
+can be used to distribute SDL DB operations to different SDL DB instances. When
+more than one DBAAS Redis sentinel group exits the selection of SDL DB instance
+is based on the namespace string hash calculation.
