Actually, if Nexenta exposes the underlying ZFS snapshot and clone 
primitives, then you're probably better off just accessing the raw files 
directly over NFS and then using the ZFS snap API for vdi_snapshot and 
vdi_clone. Is there any performance benefit to using iSCSI instead of 
NFS for the data path layer with Nexenta?
