[nog] Second hand gear from eBay

Here's my two cents.

So far we've purchased 2x Dell 8024F (24x 10GE SFP) and 2x Mellanox 
IS5025 (36x IB QDR) switches off ebay. We use them in our testing lab, 
with frequent reconfiguration, but in a closed environment. Here's a 
photo of the IB switches 
https://twitter.com/bkrosnov/status/494775865101017088 . We are 
extremely happy with these purchases.

In terms of using low-cost gear for production environments, I think 
network operators have a lot to learn from web companies. If you design 
your system so that you don't care if a few devices fail, then you don't 
depend on hardware so much. I know this is hard to achieve in complex 
network topologies, but emerging trends/technologies such as OpenFlow 
and "bare metal and white box switches" are coming to help it along.

Best regards,
