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

Storage object Limit Native storage Storage arrays Virtual storage

(Data ONTAP-v)

Aggregates Maximum per node1 100 100 60
Maximum size2 Model-dependent Model-dependent 16 TB
Minimum size3 RAID-DP: 5 disks

RAID4: 3 disks

Model-dependent 1 disk
Aggregates (mirrored) Maximum suggested per node4 64 64 N/A
RAID groups Maximum per aggregate 150 150 60

Notes:

  1. In an HA configuration, this limit applies to each node individually, so the overall limit for the pair is doubled.
  2. See the Hardware Universe.
  3. For root aggregates using physical disks, the minimum size is 3 disks for RAID-DP and 2 disks for RAID4.

    See the Hardware Universe for the minimum aggregate size for storage arrays.

  4. You can create more than 64 mirrored aggregates on a node, but doing so could cause plex synchronization problems after certain types of failures.

RAID group limits

For maximum and default RAID group sizes, see the Hardware Universe.
