Re: number of private ip address needed for clustering

The two data nodes have one port (if you set PortNumber in
config file on data node) and uses one hostname (IP address
or hostname). I gather this IP address can be a private one
if all your communication to the data nodes goes through the
MySQL Server.

The MySQL Server uses a public IP address I presume since I
gather this is your interface to the cluster.

The management server needs to reachable from the MySQL Server
and from the data nodes. The MySQL Server uses the same
hostname to connect to the data node and management server.
The management server can thus be a private IP address.

So as long as the MySQL Server can reach all the private
IP addresses of the 2 data nodes and management server then
this is the only public IP address, the rest should be
possible to use private IP addresses.

Definitely one IP per node is sufficient.
