Hi,

For Windows Server the licenses go for "Core". What operating system do you have?

The difference between taking the Standard or Datacenter version depends on what you have to do.

Here you can check how many licenses you need per Esxi host:

i use windows Server 2016 standar and Windows server 2012 Standar dispatched like below

ESXi1 : 10 VMs

ESXi 2 : 7 VMs

ESXI3 : 5 VMs

Hi,

Core-based Licensing – Windows Server 2016 Standard and Datacenter

Core-based licensing requires all physical cores in the server to be licensed. Servers are licensed based on the number of processor cores in the physical server.

Find the below points which gives you more clear picture on that

  • A minimum of 8 core licenses is required for each physical processor and a minimum of 16 core licenses is required for each server.
  • Core licenses are sold in packs of two.
  • Standard Edition provides rights for up to 2 Operating System Environments or Windows Servers containers with Hyper-V isolation when all physical cores in the server are licensed. For each additional 1 or 2 VMs, all the physical cores in the server must be licensed again

How to License Microsoft Windows Server

Basically you have to do the calculation for each Esxi host how many processors and cores have in total. considering this:

Each Windows Server license pack applies to two cores
Each Windows Server Standard license allows for two Windows Server Standard virtual instances on the covered

Hi,

So 1 copy of 2016 Standard License - 2 VMs

ESXi1: 10 VMs - 5 license 5x2=10 VMs
ESXi2: 7 VMs -  7 license 4x2=8 VMs
ESXI3: 5 VMs - 3 license 3x2=6 VMs
ESXi4: 17 VMs - 9 license 9x2=18 Vms


Datacenter License allows you to have Unlimited VMs.

So the cost of Standard against Datacenter

consider that if you migrate any VM in another host must be covered.
