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:

Storage limits for Cloud Volumes ONTAP are documented in the Cloud Volumes ONTAP Release Notes.

Notes:

  1. A volume can contain up to 1023 Snapshot copies.

  2. Beginning with ONTAP 9.12.1P2, the limit is 128 TB. In ONTAP 9.11.1 and earlier versions, the limit is 16 TB.

  3. The maximum supported number of FlexVol volumes on ETERNUS AX series with at least 128 GB of memory has increased to 2,500 FlexVol volumes per node.

  4. 2 billion = 2 × 109.

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

  6. This limit applies only in SAN environments.

  7. You can use a SnapMirror cascade deployment to increase this limit.

Note:

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

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