Hello All:
I have a client who has a 4TB database and wants to easily make clones for their DEV environment. The conventional methods (RMAN duplicate) are taking too long because of the size of the db. Looking into dNFS as an alternative standalone and looking into the ZFS storage appliance as well. What are the benefits of just dNFS being configured alone? I'm sure you can clone easily based on the copy-on-write capabilities but weighing the dNFS option alone (no additional costs) vs using ZFS Storage Appliance (which used dNFS as its protocol) but costs money. Your thoughts?
