I'm testing NSX in my nested vSphere lab, when enable NSX on cluster each nested esxi starts to use 100% of 1 pCore assigned to nested ESXi.
esxtop shows that netcpa process use 100% of resource of 1 pcore.
Also I try to reproduce that situation on physical hardware, and the result was the same, netcpa uses 100% of one pcore.
Is it normal situation? Why NSX uses so much resource.
You'll have to give more details:
-is hardware on vSphere and NSX HCL?
-physical hardware specifications
-vSphere components installed, versions and baseline functionality (is environment falling apart or functional and super fast)
-How far have you gotten with the NSX deployment...did you fully deploy solution or stop at the host preparation step when you noticed high CPU load
-are there any other problems in environment or with host/s
-is the solution licensed properly
-have you checked the netcpa log file on the ESXi host?
-have you checked the hostd log file on the ESXi host?
Thnx for your replay. As I can see in that article only said about fixed issue with CPU usage on NSX manager and not on ESXi hosts. anyway I'll test this version in my lab.
I had the same issue using NSX 6.1.3 on nested environment. I re-deployed NSX using 6.1.4 and it works like charm!
My compute cluster is using vSAN, so one thing I did this time was to set the vSAN network on different port-group than the NSX VXLAN zone. I though that vSAN traffic on top of NSX would cause this high CPU, especially in nested environments were IP packets usually get DUP-licated
