Sizing totally depends upon on the vSphere Design . You need to calculate current and future requirement and size it accordingly. You can't size the environment only based on NSX-V components (If it is a dedicated cluster it makes sense) . Just curious to know what kind of use cases you have as you since you updated you will reach maximum limitation ?
Thank you very much for your input.
Our use case is to accommodate internal multitenancy service, whose number is approx. 1000 and each of them is to leverage 1-2 Edge/DLR, 2-4 VLANs, up to 10 VXLANs.
