only half the logical processors are available on Windows Server 2016 , is it a licence issue or NUMA Configuration

Bryan12345 21 Reputation points

Using an intel chip set , two CPU's , 20 cores in each , 40 logical processers per CPU . Therefore the OS should be showing 80 logical processors.

I've tried to set the bios to set NUMA configuration to flat instead of Clustered but the 80 Logical processors are not avalaible to the JVM .

Is this an issue with Windows Server 2016 using a new Intel chipset ?

Is there a configuration setting to enable the OS to see all 80 logical processors ?

Is there a Windows Server 2016 restriction on the number of cores ?

    Cores are unlimited.

    I'd probably take this up with the server or hardware vendor. It could be a configuration or possibly a firmware issue but either case they should be well versed and will be your best resource to debug.
