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:

Aggregate limits

Limit Native storage Storage arrays Notes
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.
Aggregates (32-bit)

Maximum size

16 TB 16 TB
Aggregates (64-bit)

Maximum size

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

Minimum size

RAID-DP: 5 disks

RAID4: 3 disks

Model-dependent For root aggregates, the minimum size is 3 disks for RAID-DP and 2 disks for RAID4.

If you need a smaller non-root aggregate, you can use the force-small-aggregate option.

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