Limit	Native storage	Back-end storage arrays	Notes
Aggregates and traditional volumes (combined) Maximum per system	100	100	In an HA pair, this limit applies to each node individually, so the overall limit for the pair is doubled.
Mirrored aggregates Maximum suggested per system	64	64	You can create more than 64 mirrored aggregates on a storage system, but doing so could cause plex synchronization problems after certain types of failures.
Array LUNs Minimum size for root volume	N/A	Model-dependent	See the V-Series Support Matrix.
Files Maximum size in 32-bit FlexVol volume or traditional volume	16 TB	16 TB
Files Maximum size in 64-bit volume	16 TB	16 TB
FlexCache volumes Maximum per system	100	100
FlexVol volumes Maximum per system	All other models: 500	All other models: 500	In an HA pair, these limits apply to each node individually, so the overall limit for the pair is doubled. If you plan to perform a non-disruptive upgrade, the limitation on the number of FlexVol volumes you can have might be smaller than the numbers listed here. For more information, see the Data ONTAP 7-ModeUpgrade Guide.
FlexVol volumes Minimum size	20 MB	20 MB
FlexVol volumes (32-bit) Maximum size	16 TB	16 TB
FlexVol volumes (64-bit) Maximum size	Model-dependent	Model-dependent	See the System Configuration Guide.
FlexVol root volumes Minimum size	Model-dependent	Model-dependent	See table below.
Links (hard) Maximum per parent directory	99,998	99,998
Qtrees Maximum number per volume	4,995	4,995	Qtrees cannot be created in a striped volume.
Subdirectories Maximum per parent directory	99,998	99,998
Striped volumes Maximum size	1 PB	1 PB	16 TB per member aggregate
Traditional volumes Maximum size	16 TB	16 TB
Traditional volumes and aggregates Maximum per system	100	100	In an HA pair, this limit applies to each node individually, so the overall limit for the pair is doubled.

Aggregates (32-bit) Maximum size	16 TB	16 TB	For striped aggregates, each member aggregate can be up to 16 TB.

Limit	Native storage	Back-end storage arrays	Notes
Maximum per file or LUN	255	255	If you try to create more than 255 clones, Data ONTAP automatically creates a new physical copy of the parent file or LUN. This limit could be lower for FlexVol volumes that use deduplication.
Maximum simultaneous operations per FlexVol volume	16	16
Maximum simultaneous operations per storage system	500	500
Maximum size of FlexVol volume	16 TB	16 TB
Maximum total shared data per FlexVol volume	16 TB	16 TB	Any subsequent attempts to create FlexClone files or FlexClone LUNs after the maximum size is reached cause Data ONTAP to create physical copies of the parent file or LUN.
