[Beowulf] Switch recommendations and 10G to the desktop?

[John Hearns]

I'm looking for recommendations for 1 48 port, or two stacked 24 port,
switches for desktop users.
The aim is to bond 2xgigabit connections. I would have normally first
thought Nortel for this job.
Thoughts?

Secondly, do folks here have much experience of 10gig to the desktop?
Distance is a bit too
far for copper CX4, and fibre is pricey. I note Extreme networks have
a switch with 10G over cat6,
I guess there are others. Thoughts again please!
