Increased disk capacity in GCP (13 Mar 2020)
You can now attach up to 256 TB of persistent disks to Cloud Volumes ONTAP when using the Premium or BYOL licenses in Google Cloud. This is up from 64 TB.
Just like before, you can reach the 368 TB maximum system capacity for Premium and BYOL by combining persistent disks with data tiering to object storage.
The maximum number of data disks per system has also increased to 124 disks.

AWS updates (16 Feb 2020)
We’ve introduced support for new EC2 instances and a change in the number of supported data disks.
Support for new instances
Several new EC2 instance types are now supported with Cloud Volumes ONTAP 9.7 when using a Premium or BYOL license:
1 These instance types include local NVMe storage, which Cloud Volumes ONTAP uses as Flash Cache. Learn more.
2 The r5.12xlarge instance type has a known limitation with supportability. If a node unexpectedly reboots due to a panic, the system might not collect core files used to troubleshoot and root cause the problem. The customer accepts the risks and limited support terms and bears all support responsibility if this condition occurs.
Supported data disks
One less data disk is now supported for c5, m5, and r5 instances. For single node systems, 22 data disks are supported. For HA pairs, 19 data disks are supported per node.
Support for DS15_v2 in Azure (12 Feb 2020)
Cloud Volumes ONTAP is now supported with the DS15_v2 virtual machine type in Azure, on both single node systems and HA pairs.
9.7 GA (10 Feb 2020)
The General Availability (GA) release of Cloud Volumes ONTAP 9.7 is now available in AWS and GCP. The GA release includes bug fixes. Cloud Manager will prompt you to upgrade your existing systems to this release.
9.7 D1 for Azure (29 Jan 2020)
Cloud Volumes ONTAP 9.7 D1 is now available in Microsoft Azure.
We discovered an issue with Cloud Volumes ONTAP 9.7 and earlier, where Cloud Volumes ONTAP may not start up successfully in situations where the Azure virtual machine is restarted.
This issue is fixed in 9.7 D1 (and later). We highly recommend upgrading to the latest Cloud Volumes ONTAP version as soon as possible.

9.7 RC1 (16 Dec 2019)
Cloud Volumes ONTAP 9.7 RC1 is now available in AWS, Azure, and Google Cloud Platform. In addition to the features introduced with ONTAP 9.7, this release of Cloud Volumes ONTAP includes the following:
Flash Cache support in Azure
Cloud Volumes ONTAP now supports the Standard_L8s_v2 VM type with single node, BYOL systems in Azure. This VM type includes local NVMe storage, which Cloud Volumes ONTAP uses as Flash Cache.
Flash Cache speeds access to data through real-time intelligent caching of recently read user data and NetApp metadata. It’s effective for random read-intensive workloads, including databases, email, and file services.
Deploy new systems using this VM type or modify existing systems to use this VM type and you’ll automatically take advantage of Flash Cache.
Fix for Azure NIC detach events
This release addresses an issue with Cloud Volumes ONTAP node reboots from Azure NIC detach events. Cloud Volumes ONTAP will handle these events more gracefully and not disrupt service. Cloud Volumes ONTAP HA pairs will still perform a takeover/give back sequence from Azure freeze maintenance events, but there’s no subsequent reboot from a NIC detach that might occur during this time.
Upgrades of Cloud Volumes ONTAP must be completed from Cloud Manager. You should not upgrade Cloud Volumes ONTAP by using System Manager or the CLI. Doing so can impact system stability.
Cloud Manager will prompt you to upgrade your existing Cloud Volumes ONTAP 9.6 systems to the 9.7 release.
Another upgrade option is to use the software image from the NetApp Support Site.
Before you use this option, view the supported upgrade paths for ONTAP. The version of ONTAP that you can upgrade to varies based on the version of ONTAP currently running on your nodes.
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.
