Hi Team ,

Actually we are running virtual environment on vcenter server with 4 virtual hosts and a total of 15 virtual machines on them with applications like active directory,Exchange,SQL.

How to find out the number of V-Ray licenses needed for our virtual environment.

For reference attached the screenshot of one of our virtual host,remaining 3 virtual hosts also have the same settings .

Details of one of the host as in the screenshot.

CPU Cores : 8 CPUs x2.66GHz

processor sockets :2

cores per socket:4

Could you help me out in finding the per occupied processor socket.

Thanks in advance.
