[Bro] 10g Nic Cards

[Tyler Schoenke]

We were pricing out 64 core (4x 16 processors AMD).   Does anyone know
if the Myricom's can support load balancing to 64 cores?   I recall the
32 core limit for PF_RING.

If you go the Intel route, you'll probably want a similar license for ntop's PF_RING + DNA driver and the price comes out to be just about the same as Myricom[1]. You can opt to not get this license, but performance will suffer. Research and educational networks used to get an exemption from ntop license fees, however this is no longer the case for PF_RING + DNA since development was subsidized by Silicom. If you get a dual-port NIC, the difference becomes even more exaggerated, as the ntop license is $261 *per port* as opposed to the $295 *per card* Myricom license.

The Myricom sniffer driver doesn't require special privileges to sniff traffic, so you don't have to do funky setcap stuff - it "just works," even if you don't run Bro as root. From a simple test that someone at a large university ran, pitting a Myricom card with the Myricom sniffer driver against an Intel card with the top-of-the-line ntop driver (PF_RING + DNA + libzero - a $500 license), the Myricom card was better performing.
