Hi Marcus,

Are you looking to install the sensors out-of-band (passive only) or  
inline?  The aggregate performance you're going to get is going to  
depend on a number of factors like the configuration of the system  
and which rules you're running as well as the underlying hardware and  
the OS configuration.

Without specialized hardware you're going to be hard pressed to get  
that kind of performance out of two machines.  You could build a  
machine to try to hit those performance levels combining high  
performance systems hardware (core 2 duo/xeons, for example) and  
accelerators like those from Endace, but don't forget about the  
backend that's going to be required to manage the data the sensors  
produce and manage their configuration, etc.

We have multi-gig appliances at Sourcefire if you're looking for  
prebuilt systems, check it out if you're interested.
