Looking for help to set up RAID6+Dual SSD cache

I looked at Windows Toolbox and Windows docker, and they both seem like viable solutions for setting up multiple nodes. But, if I understand it correctly, there is no “escaping” using a unique port for each node, not even when using docker? Because if that is true, then my only option is to set up Raid and make a single large node, due to my single port restriction from my VPN.
