<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">This is very much dependent on your traffic profile. If it’s an internal deployment with lots of 10Gbps LAN traffic you will need more hardware than a border
deployment with ISP type traffic. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I would recommend starting with a 16 core, 32 (or more) Gig RAM (depending on your stream depth) system for 10Gbs and measure your system load and packet drops.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Ideally you want your NIC/cores/RAM/ring-buffer under 50% utilization per sensor, to keep packet drops around .1% or less. If you see more than .1% packet drops,
add another sensor and keep doubling the ring-size until you get the performance you want. I’ve used up to a million packets for the ring-size with no problems on my AMD Piledriver system; however on Intel deployments a smaller ring-size might be preferable.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I think there are a lot of benefits to standardizing on a modest/affordable build, use a switched load-balancer and deploy multiple sensors. That way if you
have an outage you don’t lose 100% of your visibility and you can easily expand your deployment in a predictable way. You should be sending all your alerts in json to a SIEM for indexing/alerting.
