15 of them with sniffer v3. Boring. Just works.
Myricom support is non-existent though.

I'm assuming the answer is no to finding value/purpose in the 2-port card but I wanted to get some valuable input on all of this before making any purchases of the Myricom cards.

The ability to do onboard load distribution with multiple sub interfaces is a killer feature and your Bro config is greatly simplified.  We use a patched version of libpacap for Endace.. but I hear that 2.5 may incorporate native Myricom support.

We don’t have a $1,000 dollars per a card + license to spend on the cards. Is anyone using Intel or other brands that aren’t as expensive to capture their traffic? We are looking at doing all 10 Gig connections into the Bro Cluster.
