There are many customers running 100s and 1000s of VMs over NFS. It seems like a natural way to integrate NetApp¹s storage virtualization directly with VMware, and NFS performs on par with FCP. You should try it, you¹d be surprised.

I don't speak for VMWare but I know that they are moving away from only storing ISO and templates. There are several good size implementations of vmware on nfs. We have about 2 dozen VM's running on nfs and another 40 running on FCP.

you perfectly know how much costs the NFS license! Terrible!!! iSCSI is free
(bundle) and we've tested also on huge SATA disks...no issues.
Why do you said that iSCSI implementation is horrible? It's so easy to
setup...

I have to correct you :) We did some tests with vcb and iscsi, it works fine, but vcb in general was not very convenient. And the other thing is that the iscsi implementation in esx is horrible. Use NFS to earn more flexibility and an even better performance.
That's the experience we've made.

As I told you in another mail your environment make me more persuaded that the best thing you could do is to use VCB.
VCB = VMWare Consolidated Backup?
AFAIK, it is not an option in an iSCSI environment[1] ... if this is not the case, do correct me as we are aggressively pursuing iSCSI on our 3020s as a prod means to store vmdks for ESX. :)
