Will have a look later today.

Let me know if you cannot access it and I will send it offline.

Thanks Mohammed. As you mention, some storage solutions offers ways to monitor these things. Let me know your findings.

It will display in-depth information However you need to be aware of SCSI stack. For NFS, I am not sure but i believe we can check something as well from the VNX box. I will check and get back to you. What i want to say is that there might be an alternative methods to monitor VAAI via the storage array..

Not totally accurate, but one indirect way could be to use ESXTOP while doing a full clone and in the “n” view watch the specific vmnics used by NFS and see that the network traffic should be much lower than using normal full copy through the network. 🙂

Also the IO against the datastore should be low(er) in the “u” view.
