Storage limits in Azure

Cloud Volumes ONTAP has storage configuration limits to provide reliable operations. For best performance, do not configure your system at the maximum values.
Maximum system capacity by license
The maximum system capacity for a Cloud Volumes ONTAP system is determined by its license. The maximum system capacity includes disk-based storage plus object storage used for data tiering. NetApp doesn't support exceeding this limit.
| License | Maximum system capacity (disks + object storage) |
|---|---|
Freemium |

The capacity limit is for the entire HA pair. It is not per node. For example, if you use the Premium license, you can have up to 368 TiB of capacity between both nodes.
Disk and tiering limits by VM size
The disk limits below are specific to disks that contain user data. The limits do not include the root disk, core disk, and VNVRAM.
|
The number of data disks listed in the tables below are as 9.7 P5. In previous 9.7 releases, two additional data disks were supported. Starting in 9.7 P5, Cloud Volumes ONTAP uses an additional disk for core data and another for VNVRAM. This change reduced the number of disks available for data. |
The tables below show the maximum system capacity by VM size with disks alone, and with disks and cold data tiering to object storage.
-
Single node systems can use Standard HDD Managed Disks, Standard SSD Managed Disks, and Premium SSD Managed Disks, with up to 32 TiB per disk. The number of supported disks varies by VM size.
-
HA systems use Premium page blobs as disks, with up to 8 TiB per page blob. The number of supported disks varies by VM size.

You can purchase multiple node-based licenses for a Cloud Volumes ONTAP BYOL single node or HA pair system to allocate more than 368 TiB of capacity, up to the maximum tested and supported system capacity limit of 2 PiB. Be aware that disk limits can prevent you from reaching the capacity limit by using disks alone. You can go beyond the disk limit by tiering inactive data to object storage. Learn how to add additional system licenses to Cloud Volumes ONTAP. Though Cloud Volumes ONTAP supports up to the maximum tested and supported system capacity of 2 PiB, crossing the 2 PiB limit results in an unsupported system configuration. |

For some VM types, you'll need several BYOL licenses to reach the max system capacity listed below. For example, you'd need 6 BYOL licenses to reach 2 PiB with DS5_v2. |

Aggregate limits
Cloud Volumes ONTAP uses Azure storage as disks and groups them into aggregates. Aggregates provide storage to volumes.
| Parameter | Limit |
|---|---|
Maximum number of aggregates |
Same as the disk limit |
Maximum aggregate size 1 |
384 TiB of raw capacity for single node 2 |
Disks per aggregate |
1-12 3 |
Maximum number of RAID groups per aggregate |
1 |
Notes:
-
The aggregate capacity limit is based on the disks that comprise the aggregate. The limit does not include object storage used for data tiering.
-
If using node-based licensing, two BYOL licenses are required to reach 384 TiB.
-
All disks in an aggregate must be the same size.
Logical storage limits
| Logical storage | Parameter | Limit |
|---|---|---|
Storage virtual machines (SVMs) |
Maximum number for Cloud Volumes ONTAP |
One data-serving SVM and one destination SVM used for disaster recovery. You can activate the destination SVM for data access if there’s an outage on the source SVM. 1 |

Notes:
-
Cloud Manager does not provide any setup or orchestration support for SVM disaster recovery. It also does not support storage-related tasks on an additional SVM. You must use System Manager or the CLI for SVM disaster recovery.
-
Hierarchical clone depth is the maximum depth of a nested hierarchy of FlexClone volumes that can be created from a single FlexVol volume.
