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

Limit Native storage Storage arrays Virtual storage (Data ONTAP-v) Notes
Array LUNs

Minimum size for root volume

N/A Model-dependent N/A See the Hardware Universe.
Files

Maximum size

16 TB 16 TB 16 TB  
Files

Maximum per volume

Volume size dependent, up to 2 billion Volume size dependent, up to 2 billion Volume size dependent, up to 2 billion 2 billion = 2 × 10 to the 9th power.
FlexCache volumes

Maximum per system

Snapshot copies

Maximum per FlexVol volume

255 255 255 The use of certain Data ONTAP capabilities could reduce this limit. For more information, see the Data ONTAP Data Protection Online Backup and Recovery Guide for 7-Mode.
Traditional volumes

Maximum size

16 TB 16 TB Model-dependent See the Hardware Universe.
Traditional volumes and aggregates

Maximum per system

100 100 100 In an HA configuration, this limit applies to each node individually, so the overall limit for the pair is doubled.

Aggregate limits

Limit Native storage Storage arrays Virtual storage (Data ONTAP-v) Notes
Aggregates and traditional volumes (combined)

Maximum per system

100 100 100 In an HA configuration, 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 16 TB
Aggregates (64-bit)

Maximum size

Model-dependent Model-dependent 16 TB See the Hardware Universe.
Aggregates

Minimum size

RAID-DP: 3 disks

RAID4: 2 disks

Model-dependent N/A

See the Hardware Universe for the minimum aggregate size for RAID0.

Aggregates (mirrored)

Maximum suggested per system

64 64 N/A 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.
RAID groups

FlexClone file and FlexClone LUN limits

Limit Native storage Storage arrays Virtual storage (Data ONTAP-v) Notes
Maximum per file or LUN 32,767 32,767 32,767

If you try to create more than 32,767 clones, Data ONTAP automatically creates a new physical copy of the parent file or LUN.

This limit might be lower for FlexVol volumes that use deduplication.
