Direct inter-pc connect using USB vs network connections (using Ethernet/InfiniBand)?

I have been trying to find relevant materials on this but to no vain. When it comes to inter-connecting servers/PCs (like ini data centers), why is network solutions such as Ethernet/InfiniBand preferred over USB connections?

Thank you so much for your time and help!
