Create a capacity pool for Azure NetApp Files

Creating a capacity pool enables you to create volumes within it.

Before you begin

  • You need a NetApp account.
  • If you're using Azure CLI, ensure that you're using the latest version. For more information, see How to update the Azure CLI.
  • If you're using PowerShell, ensure that you're using the latest version of the Az.NetAppFiles module. To update to the latest version, use the 'Update-Module Az.NetAppFiles' command. For more information, see Update-Module.
  • If you're using the Azure REST API, ensure that you specify the latest version.
  • If you're creating 1-TiB capacity pool, you must first register the feature:
    1. Register the feature: 
      Register-AzProviderFeature -ProviderNamespace Microsoft.NetApp -FeatureName ANF1TiBPoolSize
    2. Check the status of the feature registration:

      [!NOTE] The RegistrationState may be in the Registering state for up to 60 minutes before changing to Registered. Wait until the status is Registered before continuing.

      Get-AzProviderFeature -ProviderNamespace Microsoft.NetApp -FeatureName ANF1TiBPoolSize
      You can also use Azure CLI commands az feature register and az feature show to register the feature and display the registration status.

Steps

  1. In the Azure portal, go to your NetApp account. From the navigation pane, select Capacity pools.

    Navigate to capacity pool

  2. Select + Add pools to create a new capacity pool.
    The New Capacity Pool window appears.

  3. Provide the following information for the new capacity pool:

    • Name
      Specify the name for the capacity pool.
      The capacity pool name must be unique for each NetApp account.

    • Service level
      This field shows the target performance for the capacity pool.
      Specify the service level for the capacity pool: Ultra, Premium, or Standard.

    • Size
      Specify the size of the capacity pool that you're purchasing.
      The minimum capacity pool size is 1 TiB. You can change the size of a capacity pool in 1-TiB increments.

    [!NOTE] [!INCLUDE Limitations for capacity pool minimum of 1 TiB]

    • Enable cool access (for Standard service level only)
      This option specifies whether volumes in the capacity pool support cool access. This option is currently supported for the Standard service level only. For details about using this option, see Manage Azure NetApp Files standard storage with cool access.

    • QoS
      Specify whether the capacity pool should use the Manual or Auto QoS type. See Storage Hierarchy and Performance Considerations to understand the QoS types.

      [!IMPORTANT] Setting QoS type to Manual is permanent. You cannot convert a manual QoS capacity pool to use auto QoS. However, you can convert an auto QoS capacity pool to use manual QoS. See Change a capacity pool to use manual QoS.

    • Encryption type
      Specify whether you want the volumes in this capacity pool to use single or double encryption. See Azure NetApp Files double encryption at rest for details.

      [!IMPORTANT] Azure NetApp Files double encryption at rest supports Standard network features, but not Basic network features. See considerations for using Azure NetApp Files double encryption at rest.

      After the capacity pool is created, you can’t modify the setting (switching between single or double) for the encryption type.

      Azure NetApp Files double encryption at rest is currently in preview. If using this feature for the first time, you need to register the feature first.

      1. Register the feature: 
        Register-AzProviderFeature -ProviderNamespace Microsoft.NetApp -FeatureName ANFDoubleEncryption
      2. Check the status of the feature registration. RegistrationState may be in the Registering state for up to 60 minutes before changing toRegistered. Wait until the status is Registered before continuing. 
        Get-AzProviderFeature -ProviderNamespace Microsoft.NetApp -FeatureName ANFDoubleEncryption

      You can also use Azure CLI commands az feature register and az feature show to register the feature and display the registration status.
