You'll probably be better off looking at an infiniband-based solution. I
just picked up two dual port Mellanox 10G 8x PCIe cards and a 1m cable for
under US$200.
Aside from just bandwidth, the other advantage 1/4 of the latency of a
gigabit ethernet setup, although my suspicion is that you might lose some of
this advantage after your packets traverse through the IPoIB layers.
As I'm still waiting on my ebay purchases to arrive, I might come to regret
this advice once I actually try to set it up and configure it. *Caveat
Emptor.*
Doubt it, I have bought ebay infiniband for our LAB and 3 production POPs.
So far we have not had any problems, like you said the latency and speed
is quite worth it. http://www.robotics.net/2009/07/30/infiniband/
