+### Controlling volthawith and ONOS cluster
+
+To provide HA, resilinecy and failover ONOS can be configured in cluster mode.
+A 3 node ONOS deployment for example can be achieved via the `full` configuration:
+```bash
+TYPE=full WITH_ONOS=classic NUM_OF_ONOS=3 NUM_OF_ATOMIX=3 ./voltha up
+```
+Please note the `TYPE=full` that deploys a 3 worker nodes for k8s and `WITH_ONOS=classic` that uses the
+cluster-enabled [helm chart](https://charts.onosproject.org) for ONOS (version 2.2).
+The `NUM_OF_ONOS=3 NUM_OF_ATOMIX=3` flags set the number of Atomix nodes and ONOS nodes.
+As usual one can add as many other options, for example `CONFIG_SADIS=y`.
