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.
A good answer to a “why?” question is “why not?” This can be a great learning or practice opportunity for redundant network links and other interface challenges.
