Well, a good number of the 10-Gbit/s Eethernet cards on the market actually have dual 10GbE interfaces in one configuration or another. The most typical configuration that *I* have seen is the two bonded (20-Gbit/s) as a single logical interface with fail-over between the two physical connections. In short, to capture a single card, you basically need to be able to store 2-GByte/s *somewhere* Yes, I'm intentionally skipping the overhead calculations and keeping things overly generalized... --this is misc@ after all (; On the more modern Intel chipset systems (X58), your memory bandwidth is about 64-Gbyte/s from RAM to proc, so if you stuff the box with 128-GByte of ram, you can collect about hour's worth of capture in a sizable RAM disk. Of course, 128-GByte of 1333-MHz RAM will set you back about $15-20 thousand USD.
Your hour is way too short. s/hour/minute/ Regards, David
