@@ -27,6 +27,9 @@ VictoriaMetrics cluster consists of the following services:
 - `vmselect` - performs incoming queries using the data from `vmstorage`
 
 Each service may scale independently and may run on the most suitable hardware.
+`vmstorage` nodes don't know about each other, don't communicate with each other and don't share any data.
+This is [shared nothing architecture](https://en.wikipedia.org/wiki/Shared-nothing_architecture).
+It increases cluster availability, simplifies cluster maintenance and cluster scaling.
