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

I keep hearing how cheap 100G is compared to 40G and it doesn't seem to hold true. Prove me wrong. 

Cisco Nexus and Arista both have switches with 48x 10G ports and 2x - 6x 40G ports for under $1k. Swap those 40G for 
100G and you're at $5k - $7k. 

Am I missing some cheap switches with 100G? 

1 / 10 / 40 Gb/s switches are made with low end T2 parts like the 56450. 

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.
