vCloud director license query along with NSX/VSAN

Hi All,

I have few queries about vCloud director licensing.Could any one please help me out ?

We are going to use vSAN for this vCloud director. In vCloud director,we are going to create multiple VDCs.Each VDC belongs to one client.

License is as follows:-

1) Vcenter server-->Going to purchase instance based license.

2) VSAN--> Going to purchase CPU based(enterprise)

3) ESXi host-->Going to purchase CPU based(enterprise)

4) VROPS--->Going to purchase OS instance based license.

vCloud director:-

We are going to use Centos machine.On top of Centos,we are going to install vcloud director software.In this case,we can go and get one instance based license.  Am i right ? or any separate license is available to get per VDC or any others? 

Please note:- Multiple clients VMs will be located in vCloud director.

NSX manager OVA:- We are going to use NSX manager appliance for vCloud director(version 9.1.0).In this case,which license we should purchase ?

NSX also CPU based license? If i have 3 ESXi hosts with 4 sockets each,then i need to get 12 sockets license ?

Please check and share your valuable feedback on this.

Thanks,
