Dynomite is based on the Dynamo protocol where nodes serve keys that belong inside a token range. Differently from Cassandra, each Rack contains the full ring. Hence in RF=3 configuration the full ring is deployed in 3 Racks, whereas in RF=2 the full ring is deployed in 2 racks.
To create tokens you can use this script to generate YAMLS
Exemplar Configuration YAML files can be found in the conf directory
