Issue/Introduction

There is some difference between core licensing of vSphere and AON (Aria operation for networks).

For example: The license installed for ESXi total core is 2120 while on AON we can see 2192 core, there is a difference of 72 core license used.

The intent of the article is explain the calculation. 

Environment

VMware Aria Operations for Networks 6.x

Resolution

 

VMware vSphere

Each core in a processor (CPU) requires a Per Core license. Any processor with less than 16 cores also requires 16 Per Core licenses.

Minimum purchase unit is 16 cores per processor. Calculate the license count using: Math.max(CPU cores,16)

Use the following formula in the spreadsheet/Excel sheet to calculate the license usage, which aligns with the core usage displayed in AON.

MAX(CPU-CORES/CPU-SOCKET,16)*NO_OF_HOSTS*CPU-SOCKET

 

For example the current license usage in the AON:

 

 

 

 

We used the following formula in the spreadsheet/Excel sheet to calculate the licensing. The resulting value aligns with the license usage reported in AON.

 

MAX(CPU-CORES/CPU-SOCKET,16)*NO_OF_HOSTS*CPU-SOCKET
