Hi Enes_Afsin_Al​ 

Specific to r4600 , 4 CPU is disabled right ? and can activate using 4 upon license activation so we can have total 16 Core  ?

refer to below link i think it is possible

The r4600 model has 16 CPUs (The 4000 platform does not utilize hyperthreading/vCPUs). No CPUs are dedicated to the F5OS platform layer which is different from the mid-range and high-end rSeries appliances. In the r4600 12 CPUs are available to be assigned to tenants and 4 are disabled via licensing. The 4600 supports a maximum of two tenants. The diagram below depicts the r4600 vCPU allocation:

    Hi,

    4 CPUs are disabled in r4600 license. When you activate r4800 license, 4 CPUs will automatically become available. And a total of 16 CPUs become available.
