Hi John,
this is from Data Ontap Edge Sales and Technical FAQ (Jan2013)
https://fieldportal.netapp.com/Core/DownloadDoc.aspx?documentID=72648&contentID=75507
Can I cluster Data ONTAP-v?
Answer: Data ONTAP-v cannot be clustered. Support for backup or replication to a clustered Data ONTAP system will be available in a future release of Data ONTAP Edge.
Is there a high-availability version of Data ONTAP-v?
Answer: Data ONTAP-v runs in a single VM. There are numerous methods to have data written to disk, but Data ONTAP-v does not provide a method of high availability at this time. If there is a hardware failure or a software/hypervisor failure, the system will shut down. When the system is shut down, the data will be on disk in a consistent state or, in the case of a hardware failure, the data will be in battery-backed cache awaiting a write to the drive when system power is returned. Both situations are protected against data corruption.
cheers,
Rob
