Supported configurations for Cloud Volumes ONTAP in Google Cloud

Several Cloud Volumes ONTAP configurations are supported in Google Cloud.
Supported configurations by license
Cloud Volumes ONTAP is available in Google Cloud as a single-node system and as a high-availability (HA) pair of nodes for fault tolerance and nondisruptive operations.
Upgrading a single-node system to an HA pair isn't supported. If you want to switch between a single-node system and an HA pair, then you need to deploy a new system and replicate data from the existing system to the new system.
Cloud Volumes ONTAP can run on either a Reserved or On-demand VM instance from your cloud provider. Solutions that use other VM instance types aren't supported.

|---|---|---|---|
Maximum system capacity |
500 GiB |
With capacity-based licensing, each Cloud Volumes ONTAP system supports tiering to object storage. The total tiered capacity can scale up to the cloud provider's bucket limit. While the license does not impose capacity restrictions, you should follow the FabricPool Best Practices to ensure optimal performance, reliability, and cost efficiency when configuring and managing tiering. |

Notes:
-
1 The n1 series machines are no longer available for selection on the NetApp Console when deploying new instances of Cloud Volumes ONTAP in Google Cloud. The n1 series machines will be retained and supported only in older, existing systems. New deployments of Cloud Volumes ONTAP are supported in Google Cloud only from the 9.8 release. We recommend that you switch to the n2 series machines that are compatible with Cloud Volumes ONTAP 9.8 and later. The n1 series machines, however, will be available for new deployments made through the API.
The custom-4-16384 machine type is no longer supported with new Cloud Volumes ONTAP systems. If you have an existing system running on this machine type, you can keep using it, but we recommend switching to the n2-standard-4 machine type.
-
2 Disk limits can prevent you from reaching the maximum system capacity limit by using disks alone. You can reach the capacity limit by tiering inactive data to object storage.
-
3 Enhanced write performance is enabled when using Balanced persistent disks and Performance (SSD) persistent disks.
-
4 Beginning on August 11, 2025, the Cloud Volumes ONTAP Optimized license is deprecated and will no longer be available for purchase or renewal in the Google Cloud marketplace for pay-as-you-go (PAYGO) subscriptions. For information, refer to What's new in Cloud Volumes ONTAP.
-
5 You can deploy the next-generation C3 family VMs on Cloud Volumes ONTAP 9.18.1 and later. The c3-standard-44 and c3-standard-88 machines and their LSSD variants support Tier-1 bandwidth in Google Cloud Console by default. With C3 VM types, you can't add a disk to an existing aggregate or switch to another variant within the C3 family. Refer to Flash Cache support for more information on the LSSD variants.

The Console shows an additional supported machine type for Standard and BYOL: n1-highmem-4. However, this machine type isn't meant for production environments. We've made it available for a specific lab environment only.

Flash Cache support
Beginning with Cloud Volumes ONTAP 9.13.0, Flash Cache, high write speed, and a higher maximum transmission unit (MTU) of 8,896 bytes, are available for the following HA pair deployment instances:
-
n2-standard-16
-
n2-standard-32
-
n2-standard-48
-
n2-standard-64
You can enable Flash Cache, and high write speed when deploying an eligible instance type. To enable the higher maximum transmission unit of 8,896 bytes, you must chose VPC-1, VPC-2, or VPC-3 for the deployment. The higher MTU enables higher network throughput. For more information on launching one of these deployments, see Launching Cloud Volumes ONTAP in Google Cloud.
|
Flash cache, high write mode, and an MTU of 8,896 are feature-dependent and cannot be disabled individually within a configured instance. |
Beginning with Cloud Volumes ONTAP 9.18.1, if you select the local SSD (LSSD) variants of the C3 VMs, Flash Cache gets enabled by default. Check this table to understand the VM variant and the maximum number of LSSDs supported by them:
| VM type | Number of LSSD disks attached |
|---|---|
c3-standard-4-lssd |
1 |
c3-standard-8-lssd |
