Can you expand on "allowing both capture and writing to disk?" Carnegie
Mellon runs a Bro cluster with Myricom NICS, which works well. However, the
manager is on a box that doesn't have any workers on it (and thus doesn't
receive any traffic), so I haven't had any I/O contention from network
traffic and log writing. Is that what you're referring to?
We're seeing about 16 Gbps and dropping < 1% (around 0.1% most of the time,
I believe). That's split up over 4 rather beefy boxes, though.
