<div dir="ltr">Hi, I wanted to revive this thread as I'm currently exploring the same- 100G+ w/ Suricata. I'm specifically interested in NIC recommendations, here I see a "Napatech NT100E3-1-PTP" is being used which I will look into a bit, I also saw they offer a compact "NT200A02-SCC-2×100/40" which may be ideal for my purposes, however I wanted to poll the community a bit-<div><br></div><div>Do folks have other 100G NIC recommendations that play very well with Suricata w/ minimal administrative overhead? It could maybe even be something like 2x40G if there are more options presently, but 1x100G would likely really be best looking forward.</div><div><br></div><div>I did see that Intel is about to (or may have by now) release their 800 series NIC's w/ a 100G option FWIW. In general I haven't heard much of anything on the top 100G NIC recommendations w/ Suricata.</div><div><br></div><div>Many thanks in advance-</div><div><br></div><div>Best,</div><div><br></div><div>-Drew</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Aug 1, 2019 at 5:28 PM Peter Manev <<a href="mailto:petermanev@gmail.com">petermanev@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">@Daniel <div>What type of traffic is that and what rules are you planing on using?</div><div><br></div><div><br></div><div>Thanks</div><div><br></div><div><br><div dir="ltr">On 1 Aug 2019, at 22:19, Nelson, Cooper <<a href="mailto:cnelson@ucsd.edu" target="_blank">cnelson@ucsd.edu</a>> wrote:<br><br></div><blockquote type="cite"><div dir="ltr">

<p class="MsoNormal">Hey fellow mobsters,<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">Looking to verify that we have spec’d our hardware correctly for monitoring 100GB:<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">2 x Intel(R) Xeon(R) Gold 6136 CPU<u></u><u></u></p>
<p class="MsoNormal">256GB of RAM<u></u><u></u></p>
<p class="MsoNormal">Napatech NT100E3-1-PTP<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">The traffic will be fed via a single network tap.<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">Will this be enough hardware to deal with 100Gb/s of traffic?<u></u><u></u></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.<u></u><u></u></p>
