I don't need 32 of them, though. 2 - 6 would be fine, 4 - 6 would be ideal.

A low end 100G switch is tomahawk 32x100 or tomawhawk 2 or T3 which are all basically 128x25Gb/s asics (or Qumran/Jericho) which’s is effectively more than one asic and is priced accordingly. So a mix of 1Gb/s copper ports backed by fast silicon is not immediately forthcoming at a low price. 32x100 switches are available at order of $200 a port which seems like pretty good deal to me but you’re amortizing the silicon across all the ports. > > I ask this because the transport companies seem to have given up on 40G. > > > ----- > Mike Hammett > Intelligent Computing Solutions > http://www.ics-il.com > > Midwest-IX > http://www.midwest-ix.com >
