Noticed today that switches with 10 GbE ports are starting to become quite low in price on eBay. Is this a sign that the price is finally starting to move or are these switches junk, lacking features or not usable to attach a server or two and start playing with the speeds? I'm mostly seeing HP 2900's but there are others too. edit: maybe there are just rear stacking ports? The fronts must just be sfp 1 GbE?
