[Beowulf] Sources for Switch Performance Data

[Andrew D. Fant]

Good morning all,
      There have been many discussions over the past few months about 
suitable switches for Ethernet-based clusters, and I was wondering if 
anyone could point me towards sites that offer some sort of head-to-head 
comparisons of switch performance in cluster applications.  For obvious 
reasons, I can't afford to buy one of each and test them all myself. 
I've heard that Cisco gear can be over-priced for performance by port, 
and that some people swear by lower-cost commodity gigE switches for 
their clusters, but I am hoping to be more analytical in performance 
numbers, especially cost per sustainable mb/s per port type numbers.  If 
anyone can point me in the right direction for these sorts of numbers, I 
would be very grateful.
