Hardly good specs.
"Vantage 8500 has a latency of under 1 microsecond, and it's very power efficient in that it can deliver a 10 GE port that consumes under 10 watts of juice."
If I produced something in my military and aerospace hardened (i.e. work in a tank in a Siberian winter and in a helicopter in Iraq) world that had latency as much as that, or used more than 6 watts per 10G port I would get the sack!
