Consider this common situation. Your production cloud storage environment is nearing capacity and you need to add more costly premium cloud storage or run out of space. The cloud providers know that once they get your data in their cloud it only grows and grows — meaning more cost for you and more money in their pockets.


With the latest release of NetApp® Cloud Volumes ONTAP® (formerly ONTAP Cloud) you can now shrink your production cloud storage and put more of your cloud budget back in your pocket. Now supported for both AWS and Azure,  NetApp Cloud Volumes ONTAP was the first cloud-native data management software to introduce automated data tiering between a performance tier (SSD or HDD) and a capacity tier (object storage).


Here’s how it works. Based on policies the user defines, cold data, data not requested recently, or Snapshot™ copies of read-write volumes (the Snapshot only tiering policy) is sent automatically from the performance tier to a less-expensive capacity tier (object storage).

With the latest release of NetApp Cloud Volumes ONTAP 9.4, you can use the auto tiering policy to tier cold data blocks in a read-write volume to a capacity tier (AWS S3 or Azure Blob storage). The cold data includes not just Snapshot copies but also cold user data from the active file system. If they are read by random reads, the cold data blocks in the capacity tier become hot and move to the performance tier. If they are read by sequential reads, such as those associated with index and antivirus scans, the cold data blocks stay cold and do not move to the performance tier.


You can choose the tiering policy when you create or edit a volume in the Cloud Manager UI.

The first multicloud data tiering solution

Data tiering is now supported for both AWS and Azure.  For the first time, you can reduce your AWS and Azure storage costs by combining a performance tier for hot data (premium or standard storage) with a capacity tier for cold data (AWS S3 or Azure Blob storage). The same tiering policies that are supported in AWS are now supported in Azure.

What else is new with this release

NetApp Cloud Volumes ONTAP is now available as a supported region in AWS GovCloud.  We also made networking enhancements for SR-IOV on AWS and performance improvements with new SIDL updates.
