On the topic of networking: 10Gbps and up is pure DRM cancer.
Cables must be terminated with transceivers, and each transceiver is vendored. And all switches and interface cards expect only their brand of transceivers to be plugged into them. So you can't plug an Intel branded transceiver into an Arista switch.
So you can hack some switches to accept other vendor's transceivers (via kernel patching and flashing) or you can buy special fixed-length vender1 <-> vendor2 cables.
