Storage limits

There are limits for storage objects that you should consider when planning and managing your storage architecture.

Limits are listed in the following sections:

Volume limits

Storage object	Limit	Native storage	Storage arrays	Data ONTAP Edge
Files	Maximum size	16 TB	16 TB	16 TB
Files	Maximum per volume⁴	Volume size dependent, up to 2 billion	Volume size dependent, up to 2 billion	Volume size dependent, up to 2 billion
FlexClone volumes	Hierarchical clone depth⁵	499	499	499
FlexVol volumes	Maximum per node¹	Model-dependent	Model-dependent	200
	Maximum per node per SVM⁶	Model-dependent	Model-dependent	200
	Minimum size	20 MB	20 MB	20 MB
	Maximum size¹	Model-dependent	Model-dependent	Model-dependent
FlexVol volumes for primary workloads	Maximum per node ²	Model-dependent	Model-dependent	Model-dependent
FlexVol root volumes	Minimum size¹	Model-dependent	Model-dependent	Model-dependent
LUNs	Maximum per node⁶	Model-dependent	Model-dependent	1,024
	Maximum per cluster⁶	Model-dependent	Model-dependent	1,024
	Maximum per volume⁶	Model-dependent	Model-dependent	512
	Maximum size	16 TB	16 TB	16 TB
Qtrees	Maximum per FlexVol volume	4,995	4,995	4,995
Snapshot copies	Maximum per volume⁷	255/1023	255/1023	255/1023
Volumes	Maximum per cluster for NAS	12,000	12,000	200
Volumes	Maximum per cluster with SAN protocols configured	Model-dependent	Model-dependent	200

Notes:

In ONTAP 9.5 and later, a volume can contain up to 1023 Snapshot copies.
Beginning in ONTAP 9.7, the maximum supported number of FlexVol volumes on AFA platforms with at least 128 GB of memory has increased to 2,500 FlexVol volumes per node; however, only 1,000 volumes per node can be active (primary workloads) at one time.
For platform-specific information and for the latest support details, see Lenovo Press.

2 billion = 2 × 10 to the 9^th power.
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.
SAN Configuration Guide
You can use a SnapMirror cascade deployment to increase this limit.

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.
