How does this compare to putting OVS on a Raspberry Pi and using it as a OpenFlow/SDN switch?
The advantage of the Zodiac FX is that it have three OpenFlow ports and one traditional port builtin. You don' have to buy USB network adapters and hubs. So, it is a ready to go package. It also gives you a different design and layout to Open vSwitch - 10 tables, a CLI designed for a switch etc.
