I wouldn't say that used or grey market really count as viable options. If we count that, I can get 1GbE for free. The reality is that for a unit that is supported (both software releases and warranty) properly for deployment in mission critical situations, 10GbE costs ~10x 1GbE. While the options you mention have their place, I would not say that any of them are "supported properly" The ubiquiti unit would be very interesting to see, but the lack of support structure would steer me away for anything mission critical. Might be great for test-bed or home use, though. Back on the original topic, I could certainly see a potential for 2.5 or 5 GbE (even optical) if the pricing was better than 10GbE. My guess is that by the time 2.5/5 is really available, 10GbE will be enough more affordable to skip over the 2.5/5 stuff. thanks, -Randy ----- On Jan 28, 2016, at 1:38 PM, Josh Reynolds josh@kyneticwifi.com wrote:

EX4500 runs me about $3200-3600 on the gray market, with 2 AC power supplies and licensing for MPLS.

Working SFP+ optics from fiberstore.com from $6 on up.

Also Quanta BMS T3048-LY8 w/ Cumulus Linux, between $3,800-$4,500.

Ubiquiti is also working on releasing a 12 port SFP+ with 4x10GBaseT, pricing will be very low.

It's out there, you just have to look for it.

I'd love to know what model Juniper you are getting for $102 per 10GbE port and where you are getting it. The lowest-end 10GbE switch is the EX4600, which lists at more like $850 per port. You can get higher-end ones with much larger port counts and get the cost/port down to about half that, but I can't imagine what you could be talking about for $102/port.

I would kill for a 24-port 10GbE Juniper switch for ~$2,500. You can't even get a 24-port 1GbE for that.

You're buying your switches and optics in the wrong places.

An SFP+ 10K w/ DOM is running me a little under $34. An SFP+ port runs me slightly over $102. (Juniper)

The standard 24 or 48 port SFP+ switch is 10 times the price of the equivalent switch with 24 or 48 port SFP. The same is true for the optics.

2.5 and 4 Gbit/s SFP modules are available and cheap. It is just that ethernet ports will not take advantage of the extra speed. So it is only useful on fibrechannel ports.

It would be an improvement if we can get 2.5 or 4 Gbit/s ethernet on SFP instead of paying for an all SFP+ switch.
