I have 3 low-end servers with only one ethernet port each that I use for Internet connection. Now I would like to have a second Ethernet interface to each 3 servers to a file server so that reading and writing to the file server would not impact the network connection.
An idea would be to use a separate ethernet switch and USB-C to Ethernet adapters for every server. However it feels like an awful waste of hardware and also complicated.
Would it be possible to connect a USB-C cable directly from each of the low-end servers to the file server and have the file server emulate Ethernet over USB?
I am planning to install Linux on the file server.
