> There was some earlier comment in this discussion about not using NFS datastores for Postgres VMDK's. Would you think you'd see a difference in scalability behavior or performance in these tests if a NFS datastore would be used instead? Provided the architecture is properly setup for that, with high speed low latency networking, and fast NAS storage. > Though not first-hand experience, my understanding is that performance is not near the top of the list of considerations when weighing different storage protocols.
