Oops. Meant to say VMware + NFS + Netapp Snapshot.

I’ll give my coworker Chauncey full credit for pointing out the recent paper by VMware on the subject of protocol performance at http://www.vmware.com/files/pdf/storage_protocol_perf.pdf. I’m reluctant to join a religious conversation about FCP vs NFS and really don’t mean to stir the pot but just thought I’d put it out there to foster technical discussion.

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.
