It would be trivial to do this with a Zedboard.

Well, need two network ports. Haven't figured out much on interfacing the thing to offboard gear (I'd have liked it if it had a pci interface). So is interfacing up a second network card "trivial" on the I/Os provided?

And wanted esata, or some high speed disk I/O interface for captures.

I'd rather like to continue forward on the zedboard front. The prospect of designing an ethernet chip that actually could incorporate fq_codel etc is very exciting. The RGII interface is available to access directly, in particular.

Well, I see it for 320. Then you need to add a SSD, and a decent network card, and I suppose it could be made to work. Awful big, tho, in an era where I can get 1/2TB on an 2.5 inch SSD.

What I'd wanted was closer to a dreamplug - 160 bucks, two network ports, but with an internal SSD. bonus points if it fit into a 1U rack and ate as little power as possible.

Principal use case here is to be a "network monitor" with enough oomph to run stuff like cacti/mrtg/snmp tools, as well as do captures off of a mirrored switch port.

 I know this is no where near an embedded device but I just got one of these
 on sale (new model out) for $220 and I think it's the most useful all-round
 cheap server box I've ever seen. Some people have it running 16 GB ram and
 I've got mine booting off an SSD via external eSATA. Very well built with 2
 x half height PCI slots (4 x eth port card?). Only missing USB3 ports and
 hot-swap drive space. And, very quiet with just an SSD.


I'd be very interested to know how fast it could do packet header captures.

Line rate (gigE) would be good. 

Does it do BQL? (what is the onboard ethernet chips)
