Hi, I have little idea how much internet bandwidth a mining rig requires. Does it vary greatly between a 6 GPU or 13 GPU rig ?
For 12 rigs in front of a 16 port Switch, is a 100Mbps Switch fine or should you go for 1Gbps ?
Gigabit all the time. Fast ethernet is really old. All those routers, switches and hubs with Fast ethernet will use old and slow chips. You need best ping possible.
