Vertica cluster diagrams?

HI All -- new to Vertica.... if they exist can someone point me to server architecture diagrams? I'm looking for best practice and am mostly interested in redundant network connectivity for the cluster and public networks. We'll be spinning up a 3 node CE cluster to start with + a Hadoop node (and eventual cluster) with the plan to scale to enterprise. I reviewed all the stock documentation, but it doesn't cover the network connectivity requirements in detail. Thanks in advance for any help.
