<p class="MsoNormal">Hey fellow mobsters,<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Looking to verify that we have spec’d our hardware correctly for monitoring 100GB:<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">2 x Intel(R) Xeon(R) Gold 6136 CPU<o:p></o:p></p>
<p class="MsoNormal">256GB of RAM<o:p></o:p></p>
<p class="MsoNormal">Napatech NT100E3-1-PTP<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">The traffic will be fed via a single network tap.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Will this be enough hardware to deal with 100Gb/s of traffic?<o:p></o:p></p>
<p class="MsoNormal">At the very least it would be great to know if the CPU and RAM is enough, we can work with Napatech to get the right card.<o:p></o:p></p>
