Creating your file...
There are limits for storage objects that you should consider when planning and managing your storage architecture.
Limits are often platform dependent. Refer to the NetApp Hardware Universe to learn the limits for your specific configuration. See Navigate the NetApp Hardware Universe for instructions on identifying the appropriate information for your ONTAP configuration.
Limits are listed in the following sections:
Storage limits for Cloud Volumes ONTAP are documented in the Cloud Volumes ONTAP Release Notes.

Notes:
-
In ONTAP 9.3 and earlier, a volume can contain up to 255 Snapshot copies. In ONTAP 9.4 and later, a volume can contain up to 1023 Snapshot copies.
-
Beginning with ONTAP 9.12.1P2, the limit is 128 TB. In ONTAP 9.11.1 and earlier versions, the limit is 16 TB.
-
Beginning with ONTAP 9.7, the maximum supported number of FlexVol volumes on AFF platforms with at least 128 GB of memory has increased to 2,500 FlexVol volumes per node.
For platform-specific information and for the latest support details, see Hardware Universe.
-
2 billion = 2 × 109.
-
The maximum depth of a nested hierarchy of FlexClone volumes that can be created from a single FlexVol volume.
-
This limit applies only in SAN environments.
-
You can use a SnapMirror cascade deployment to increase this limit.
FlexClone file and FlexClone LUN limits
Limit | Native storage | Storage arrays |
---|---|---|
Maximum per file or LUN1 |
32,767 |
32,767 |
Maximum total shared data per FlexVol volume |
640 TB |
640 TB |
Note:
-
If you try to create more than 32,767 clones, ONTAP automatically creates a new physical copy of the parent file or LUN.
This limit might be lower for FlexVol volumes that use deduplication.
