I'm also curious to know if there's a general formula to determine the required number of IB swicthes (given their ports count) to create a full (or half) bisectional network capable of interconnecting say N leaf nodes, and especially, if there's a way to deterministically infer the manner to (inter)connect them. I've seen numerous examples involving small amounts of nodes and swicthes, but I can't figure a way to scale those examples to larger networks. Any pointers?
