Re: R: R: VMware - snap

For those of you who have worked with both block protocols and NFS in VM environments, do you see NFS+NetApp as a game changing solution going forward? I do, and I hope NetApp does. I think if the price for the NFS license was more reasonable, the adoption rate of NFS would skyrocket.

iSCSI was great when it came out, and NetApp gave away the license for free. But iSCSI, in IMHO, didn’t have an application like VMWare to drive it. NFS+NetApp does, and I hope they take advantage of it.

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