Hi all, We are planning to use a cheap dual core Atom box as a nprobe system. One of the doubts that come to our mind is what card to employ.
The expensive alternative would be an Intel 82576 based card. We are aware they have great performance and are able to manage 4 RX and 4 TX queues. Also they are supported by TNAPI, but I dont know if TNAPI would be able to employ all its power as the motherboard / CPU might lack specific stuff (IOAT, DCA, ...) The alternative would be a Intel 82574 card. In this case we would only have 2 RX and 2 TX queues and lack TNAPI support. The advantage, 100€ less of cost and no leave the PCIE socket free (as the card is embedded in the motherboard). Do you guys have any experience or advice? The CPU comes with just 2 cores but as Atom supports HT that would be seen as 4, and we could balance the queues on each of them. Would using a HT "core" improve performance? Would this box suffice to monitor a 1GE link (dual card, 1Gbps in and 1Gbps out) Any experience on the number of packets per second? Very thankful in advance.
