What's new in Cloud Volumes ONTAP 9.11.0

Contributors netapp-bcammett netapp-rlithman

Cloud Volumes ONTAP 9.11.0 includes a new enhancement.

Additional features and enhancements are also introduced in the latest versions of BlueXP. See the BlueXP Release Notes for details.

Support for Elastic Volumes (7 June 2022)

Support for the Amazon EBS Elastic Volumes feature with a Cloud Volumes ONTAP aggregate provides better performance and additional capacity, while enabling BlueXP to automatically increase the underlying disk capacity as needed.

Support for Elastic Volumes is available starting with the 3.9.19 release of the BlueXP Connector and is supported with specific Cloud Volumes ONTAP versions and specific EBS disk types.

9.11.0 P1 (2 May 2022)

The Cloud Volumes ONTAP 9.11.0 P1 release is now available in AWS, Azure, and Google Cloud. This release includes the following enhancement.

ONTAP S3 support in AWS

You can now provide S3 object storage from Cloud Volumes ONTAP in AWS (Microsoft Azure is already supported). Cloud Volumes ONTAP supports S3 as an option for scale-out storage, in addition to classic file-based protocols like NFS and SMB.

Note the following:

  • The main use case for ONTAP S3 with Cloud Volumes ONTAP is a general purpose object store.

  • At this time, the S3 protocol is not supported with Cloud Volumes ONTAP in Google Cloud.

  • BlueXP doesn't provide any management capabilities for the ONTAP S3 feature.

Upgrade notes

Read through these notes to learn more about upgrading to this release.

How to upgrade

Upgrades of Cloud Volumes ONTAP must be completed from BlueXP. You should not upgrade Cloud Volumes ONTAP by using System Manager or the CLI. Doing so can impact system stability.

Supported upgrade path

You can upgrade to Cloud Volumes ONTAP 9.11.0 from the 9.10.1 release. BlueXP will prompt you to upgrade eligible Cloud Volumes ONTAP systems to this release.

Required version of the Connector

The BlueXP Connector must be running version 3.9.18 or later to upgrade existing systems to 9.11.0.

Tip Automatic upgrades of the Connector are enabled by default so you should be running the latest version.


  • The upgrade of a single node system takes the system offline for up to 25 minutes, during which I/O is interrupted.

  • Upgrading an HA pair is nondisruptive and I/O is uninterrupted. During this nondisruptive upgrade process, each node is upgraded in tandem to continue serving I/O to clients.

Upgrades in AWS with c4, m4, and r4 EC2 instance types

In AWS, the c4, m4, and r4 EC2 instance types are no longer supported with new Cloud Volumes ONTAP deployments. If you have an existing system that's running on a c4, m4, or r4 instance type, you must change to an instance type in the c5, m5, or r5 instance family. If you can't change the instance type, you need to enable enhanced networking before upgrading.

Refer to NetApp Support to learn more about the end of availability and support for these instance types.
