Only few gateways are having 8 or 16 cores license applied. For example 8 core license is applied on 28 core system, which means that those 8 CP cores (CPU0-7) are assigned only to one physical CPU. In case that in BIOS i'll&nbsp; set amount of cores on each CPU to have only 4 cores, it will then utilise both physical CPU's and running CPU 0-3 on CPU1 and CPU 4-7 on CPU2.</P><P></P><P>Did somebody using this approach on open servers?</P></BODY></HTML> Wed, 02 Jan 2019 11:15:25 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20379#M89968 Martin_Valenta 2019-01-02T11:15:25Z Re: Open server - disable CPU cores https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20380#M89969 <HTML><HEAD></HEAD><BODY><P>I'm also using this approach as the number of licensed CPU cores should match the number of physical CPU cores seen by the system. In case you don't limit the number of physical CPU cores to the licensed number you can't trust CPU performance monitoring, which means you can't rely on what SmartView Monitoring, cpview and Check Point Healthcheck is showing.</P></BODY></HTML> Wed, 02 Jan 2019 14:31:32 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20380#M89969 Danny 2019-01-02T14:31:32Z Re: Open server - disable CPU cores https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20381#M89970 <HTML><HEAD></HEAD><BODY><P>where is mentioned that it must match? <img id="smileyhappy" class="emoticon emoticon-smileyhappy" src="https://community.checkpoint.com/i/smilies/16x16_smiley-happy.png" alt="Smiley Happy" title="Smiley Happy" />&nbsp;</P></BODY></HTML> Wed, 02 Jan 2019 14:33:04 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20381#M89970 Martin_Valenta 2019-01-02T14:33:04Z Re: Open server - disable CPU cores https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20382#M89971 <HTML><HEAD></HEAD><BODY><P>Licensing asside, what are you hoping to achieve with this configuration?</P></BODY></HTML> Wed, 02 Jan 2019 14:36:36 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20382#M89971 Chris_Atkinson 2019-01-02T14:36:36Z Re: Open server - disable CPU cores https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20383#M89972 <HTML><HEAD></HEAD><BODY><P>With reducing amount of cores per CPU, it should have a slightly better performance i guess, when it will be using both physical CPU's</P></BODY></HTML> Wed, 02 Jan 2019 14:38:20 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20383#M89972 Martin_Valenta 2019-01-02T14:38:20Z Re: Open server - disable CPU cores https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20384#M89973 <HTML><HEAD></HEAD><BODY><P>We are using Nagios XI and custom scripts written to collect (snmp,ssh) and present all needed data.</P></BODY></HTML> Wed, 02 Jan 2019 14:58:38 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20384#M89973 Martin_Valenta 2019-01-02T14:58:38Z Re: Open server - disable CPU cores https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20385#M89974 <HTML><HEAD></HEAD><BODY><P>Agree with Danny here, having a mismatch between number of physical vs. licensed cores on open hardware can also cause what I call the trial license "core crunch" in my book, where many different Firewall Worker instances fight each other for the few licensed cores.&nbsp; Result: they all lose, at least performance-wise.</P><P></P><P style="color: #333333; background-color: #ffffff; border: 0px;">--</P><P style="color: #333333; background-color: #ffffff; border: 0px;">CheckMates Break Out Sessions Speaker</P><P style="color: #333333; background-color: #ffffff; border: 0px;">CPX 2019 Las Vegas &amp; Vienna - Tuesday@13:30</P></BODY></HTML> Thu, 03 Jan 2019 14:56:48 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Open-server-disable-CPU-cores/m-p/20385#M89974 Timothy_Hall 2019-01-03T14:56:48Z
