Sorry I know this is old, but I am posting for future readers. If you require a report from the Common Criteria Portal https://www.commoncriteriaportal.org/products/ (search for NetApp) the direct URL for the TOE is here https://www.commoncriteriaportal.org/files/epfiles/NetApp%20ONTAP%209.1%20ST%20v1.3.pdf
The document does cover "Domain Separation", which is NetApp's SVM separation for Secure Multi Tenancy (SMT).
Also a 3rd party did an audit testing on Secure Multi Tenancy (SMT) and you can find this in the document here TR-4512: NetApp Secure Multi-Tenancy (SMT) Validation Report.
Note: The document is on Field Portal so customers will need to talk to a NetApp partner or NetApp account team.
