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 Notes
Array LUNs

Minimum size for root volume

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

Maximum size

16 TB 16 TB  
Files

Maximum per volume

Volume size dependent, up to 2 billion Volume size dependent, up to 2 billion 2 billion = 2 × 10 to the 9th power. Directories are also counted against this limit.
FlexCache volumes

Maximum per node

100 100  
FlexClone volumes

Hierarchical clone depth

499 499 The maximum depth of a nested hierarchy of FlexClone volumes that can be created from a single FlexVol volume.
FlexVol volumes

Maximum per node

Model-dependent Model-dependent See the Hardware Universe.
FlexVol volumes

Maximum per node per Vserver

Infinite Volumes

Minimum size

Infinite Volumes

Maximum number of nodes

10 10 This limit is the maximum number of nodes upon which the aggregates associated with an Infinite Volume can be located. The maximum number of nodes in the cluster is unaffected by the presence of Infinite Volumes.

Aggregates

Maximum per node

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

Maximum per cluster for NAS

12,000 12,000 Infinite Volumes do not count against this limit, but their constituent volumes do.
Volumes

Maximum per cluster with SAN protocols configured

Infinite Volumes do not count against this limit, but their constituent volumes do.

FlexClone file and FlexClone LUN limits

Limit Native storage Storage arrays Notes
Maximum per file or LUN 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.
