i heard that in NSX-T, we don't need vsphere essentially like NSX-NV
so what will be the use cases of vSphere 6.7 or 7 without nsx-nv platform ?
You mean NSX-V, there is no such thing as NSX-NV.
NSX-T can indeed function with or without vSphere.
This article may help you: NSX-T vs NSX-v – What Is the Difference?
Not sure what you mean by your question on use cases though, can you elaborate or explain in more detail?
thank you for your reply..
some are saying for learning NSX-T, knowing vSphere is not required thats why i am wondering then what vsphere will do if not required in NSX-T ?
What do you mean by “what vSphere will do”?
Just because NSX-T can run without it doesn’t mean that vSphere has no future, or that the networking functions within vSphere serve no purpose.
vSphere 6.7 still has a lot of networking capabilities regardless of any version of NSX: https://docs.vmware.com/en/VMware-vSphere/6.7/vsphere-esxi-vcenter-server-67-networking-guide.pdf
