Chat in my nerds irc channel about 10G routers paralleling this

14:21 <b> the Xeon D-1540 has 8 cores / 16 threads, 2GHz base clock with 
              2.6GHz turbo, and dual 10G nics on chip
14:21 <b> 45W TDP

Right, but that's a pretty lame clock.

14:31 <b> supposedly an asrock board is coming that can be 10Gbase-T or SFP+

Also the only one so far I've seen able to support multiple PCIe.  The 
Supermicro is mini-ITX.  But the AsRock has some weird power arrangement
too.

14:58 <a> supermicro are shipping some SFP+ 10G E5 boards
15:00 <b> but the xeon E5 doesn't have the on die 10G nic
15:07 <a> X9DRW-7TPF+

http://www.supermicro.com/products/motherboard/xeon/c600/x9drw-7tpf_.cfm

Yes, but that's a big wattsy thing.  The X10SRW comes in some 1U variants
that can handle two PCIe so it'd be an interesting router platform that 
does not eat lots of space.

Also: 1.4Mpps per 10G link doesnt seem like the minimum packetsize one wants for
handling DOS attacks, but I might be bad at math.

Always an issue.
