Requirements and considerations for large volumes (preview)

  • Article

This article describes the requirements and considerations you need to be aware of before using large volumes on Azure NetApp Files.

Register the feature

The large volumes feature for Azure NetApp Files is currently in public preview. This preview is offered under the Supplemental Terms of Use for Microsoft Azure Previews and is controlled via Azure Feature Exposure Control (AFEC) settings on a per subscription basis.

To enroll in the preview for large volumes, use the large volumes preview sign-up form.

Requirements and considerations

The following requirements and considerations apply to large volumes. For performance considerations of regular volumes, see Performance considerations for Azure NetApp Files.

  • Existing regular volumes can't be resized over 100 TiB.

  • You can't convert regular Azure NetApp Files volumes to large volumes.

  • You must create a large volume at a size of 50 TiB or larger. A single volume can't exceed 500 TiB.

  • You can't resize a large volume to less than 50 TiB. A large volume cannot be resized to less than 30% of its lowest provisioned size. This limit is adjustable via a support request.

  • Large volumes are currently not supported with Azure NetApp Files backup.

  • Large volumes aren't currently supported with cross-region replication.

  • You can't create a large volume with application volume groups.

  • Large volumes aren't currently supported with cross-zone replication.

  • Currently, large volumes aren't suited for database (HANA, Oracle, SQL Server, etc.) data and log volumes. For database workloads requiring more than a single volume’s throughput limit, consider deploying multiple regular volumes.

  • Throughput ceilings for the three performance tiers (Standard, Premium, and Ultra) of large volumes are based on the existing 100-TiB maximum capacity targets. You're able to grow to 500 TiB with the throughput ceiling per the following table:

    Capacity tier Volume size (TiB) Throughput (MiB/s)
    Standard 50 to 500 1,600
    Premium 50 to 500 6,400
    Ultra 50 to 500 10,240

  • Large volumes aren't currently supported with standard storage with cool access.

Configure large volumes

Important

Before you can use large volumes, you must first request an increase in regional capacity quota.

Once your regional capacity quota has increased, you can create volumes that are up to 500 TiB in size. When creating a volume, after you designate the volume quota, you must select Yes for the Large volume field. Once created, you can manage your large volumes in the same manner as regular volumes.
