How many ports per switch do I need to dedicate to stacking? 40G ports? 10g ports?

Which is the recommended stack bandwidth for S6720 stack?

How can you calculate the bandwidth needed and how does it impact in the stack performance?

there is no bandwidth requirement for the stack link, but considering the actual situation, it's recommened that the stack link bandwidth is equal or greater than the uplink bandwidth of one of the stack member.
by the way, to prevent the stack failure incidentally, at least two links are needed incase that one link faliure leads the stack failure.
