[Bioclusters] bio/life science cluster switch

[Steve]

I'm putting together a general lifescience based cluster (software 
ranging from docking apps. to blast). Its going to consist of 
approximately 100 nodes, including 2 head nodes. All nodes will be 
connected through GIGE, and we will not be using high speed interconnects.

In the past I've used Cisco switches (4000 and 6000 series), stable, 
reliable and costly.
Does anyone have any recommendations? I've had mixed reviews about 
Extreme, so I'd be interested in Foundy, Procurve or any systems people 
may have had success with.

Cheers,

Steve
