Interesting. I was going to be skeptical and say that even a single 25 gbps fiber would spew data too fast for memory / bus to keep up, but I looked up some specs and apparently it's possible on cutting-edge hardware. And if you're dividing a single fiber's bandwidth among multiple machines, presumably each machine's network interface would be able to filter packets it doesn't care about, so this objection wouldn't apply.
