[Beowulf] layer 3 switches

We have tested the 5500 series Nortel switches in our cluster 
environment and have seen good performance with them.  I'm not so sure 
I'll buy 3Com again.  Their little foray out of real networking and then 
claiming to come back didn't give me a warm fuzzy feeling.

I've also got some Force10 S50's we've been using.  They work well but 
are really too expensive for something like this.  With performance 
equivalent to the 550 series, and almost a 2x cost premium, I'm not 
likely to go back there.
