I am building my personal private cloud. I am considering using second hand dell optiplexes as worker nodes, but they only have 1 NIC and I’d need a contraption like this for my redundant network.
Then this wish came to my mind. Theoretically, such a one box solution could be faster than gigabit too.
I cant speak to that brand specifically, but the USB ethernet adapters I have used are super unreliable. I have had 2 burn out randomly (out of 3). So it might not be as redundant as you would like.
