SQL Licensing

I have 5 ESXi hosts & all the 5 ESXi hosts will form a single VMware cluster.
I believe the SQL licenses is based on the physical core CPUs.

So in this case if I form a single VMware Cluster & if I want my SQL servers to be part of only 2 hosts still do I need to have license for all the 5 ESXi hosts.
I want my SQL servers to be available in only 2 hosts. But all the 5 ESXI severs form a single VMware cluster.
How should i license it. Should i consider license for 2 hosts or I need to consider for 5 hosts.

Hi

 The licenses are given on total  users that connect to the DB and the other one is Core based. So if you know the correct count of users then you can go for User based or else Core would be ideal.

This thread has similar, discussion which can be of some help.

I am targeting not on the no of users but on cores.
So for my above scenario for how many servers should we consider the licensing.

All hosts need licenses! look at the 90 days rules in License Mobility.

Unless you can prove, that you will only "lock down your VMs to two hosts", using DRS rules.

The current Microsoft SQL Guides are here

Hi,
use DRS must rules for VM-Host placement. That should do the job for you.
