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 14:31 <b> supposedly an asrock board is coming that can be 10Gbase-T or SFP+ 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 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. /kc On Tue, May 19, 2015 at 03:46:16PM -0500, Joe Greco said: >> How cheap is cheap and what performance numbers are you looking for? >> >> About as cheap as you can get: >> >> For about $3,000 you can build a Supermicro OEM system with an 8-core Xeon >> E5 V3 and 4-port 10G Intel SFP+ NIC with 8G of RAM running VyOS.
