Good move. I have my home network and its home lab the same way I run my work networks and server clusters:
- Management network over regular copper ethernet. This is what’s routed over VPN for remote access. IPMI also connects here for when something really stupid happens.
- High speed fiber connecting all the servers. Not routed out - it’s only used for comms between the servers. This serves as a backup in case the management port dies. It has saved me a couple of times: shell in to one of the others the normal way, the from there I can jump into any other server via the fiber connection.
Additionally:
Normal and antinormal - perpendicular to prograde and retrograde.
