Storage limits for Cloud Volumes ONTAP 9.6 in GCP Edit on GitHub Request doc changes

Contributors netapp-bcammett

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.

For the Premium and BYOL licenses, disk limits prevent you from reaching the 368 TB capacity limit by using disks alone. You can reach the 368 TB capacity limit by tiering inactive data to object storage. Refer to the disk limits below for more details.

License Maximum system capacity (disks + object storage)

Explore

2 TB (data tiering is not supported with Explore)

Standard

10 TB

Premium

368 TB

BYOL

368 TB

Disk and tiering limits

The table below shows the maximum system capacity with disks alone, and with disks and cold data tiering to object storage. The disk limits are specific to disks that contain user data. The limits do not include the boot disk and root disk.

Parameter Limit

Maximum disks per system

16

Maximum disk size

16 TB

Maximum system capacity with disks alone

64 TB

Maximum system capacity with disks and cold data tiering to a Google Cloud Storage bucket

368 TB

Aggregate limits

Cloud Volumes ONTAP groups Google Cloud Platform disks into aggregates. Aggregates provide storage to volumes.

Parameter Limit

Maximum number of aggregates

16

Maximum aggregate size

64 TB of raw capacity 1

Disks per aggregate

1-6 2

Maximum number of RAID groups per aggregate

1

Notes:

  1. The aggregate capacity limit is based on the disks that comprise the aggregate. The limit does not include object storage used for data tiering.

  2. 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
(HA pair or single node)

One data-serving SVM and one or more SVMs used for disaster recovery. 1

The one data-serving SVM spans the entire Cloud Volumes ONTAP system (HA pair or single node).

Files

Maximum size

Maximum per volume

Volume size dependent, up to 2 billion

FlexClone volumes

Hierarchical clone depth 2

FlexVol volumes

Maximum per node

Minimum size

20 MB

Maximum size

Dependent on the size of the aggregate

Qtrees

Maximum per FlexVol volume

4,995

Snapshot copies

Maximum per FlexVol volume

1,023

Notes:

  1. Cloud Manager does not provide any setup or orchestration support for SVM disaster recovery. It also does not support storage-related tasks on any additional SVMs. You must use System Manager or the CLI for SVM disaster recovery.

  2. Hierarchical clone depth is the maximum depth of a nested hierarchy of FlexClone volumes that can be created from a single FlexVol volume.
