NFSv3

Yes

Yes

NFSv4

Yes

To access cache volumes using NFSv4.x protocol, both the origin and cache clusters must be using ONTAP 9.10.1 or later. The origin cluster and FlexCache cluster can have different ONTAP versions, but both should be ONTAP 9.10.1 and later versions, for example, the origin can have ONTAP 9.10.1, and the cache can have ONTAP 9.11.1.

Yes

Supported beginning with ONTAP 9.10.1.

NFSv4.2

Yes

No

SMB

Yes

Yes

Supported beginning with ONTAP 9.8.

Autonomous ransomware protection

Yes

Supported for FlexVol origin volumes beginning with ONTAP 9.10.1, not supported for FlexGroup origin volumes.

No

Antivirus

Yes

Not applicable

If you configure antivirus scanning at the origin, it is not required on the cache. The origin antivirus scanning detects files infected with viruses before writes are committed, regardless of the write source.

Auditing

Yes

You can audit NFS file access events in FlexCache relationships using native ONTAP auditing. For more information, see Considerations for auditing FlexCache volumes

No

Quotas

Yes

Quota enforcement on FlexCache origin volumes is supported for users and groups.

No

With FlexCache writearound mode (the default mode), writes on the cache are forwarded to the origin volume. Quotas are enforced at the origin.

SVM DR configuration

Yes

The primary SVM of an SVM DR relationship can have the origin volume; however, if the SVM DR relationship is broken, the FlexCache relationship must be re-created with a new origin volume.

No

You can have FlexCache volumes in primary SVMs, but not in secondary SVMs. Any FlexCache volume in the primary SVM is not replicated as part of the SVM DR relationship.
