From the datasheet it follows that the DL160 G6 \ DL165 G7 has a built-in dual port network card HP NC362i on Intel 82576. I have a HP Proliant SE316M1 (aka DL160 G6, but only SE). Put the Intel E1G42ET. I want to integrate the ports in the link aggregation of both the integrated network card and the Intel E1G42ET and use it as a software router. The load will be big (for me)): ~ 2Gbps at 300Kpps. Should I use the built-in network card or better buy another intel E1G42ET? I would put something on an Intel 82599 but there is nowhere to stick it in (in the bright future I will do so)).
