Managing storage for on-prem ONTAP clusters

Contributors

After you discover your on-prem ONTAP cluster from Cloud Manager, you can open the working environment to provision and manage storage.

Creating volumes

Cloud Manager enables you to create NFS or CIFS volumes on existing aggregates. You can’t create new aggregates on an on-prem ONTAP cluster from Cloud Manager.

A Cloud Manager feature called "templates" enables you to create volumes that are optimized for the workload requirements for certain applications; such as databases or streaming services. If your organization has created volume templates that you should use, follow these steps.

Steps
  1. On the Canvas page, double-click the name of the on-prem ONTAP cluster on which you want to provision volumes.

  2. Click Add New Volume.

  3. Follow the steps in the wizard to create the volume.

    1. Details & Protection: Enter basic details about the volume and then select a Snapshot policy.

      Some of the fields on this page are self-explanatory. The following list describes fields for which you might need guidance:

      Field Description

      Size

      The maximum size that you can enter largely depends on whether you enable thin provisioning, which enables you to create a volume that is bigger than the physical storage currently available to it.

      Snapshot Policy

      A Snapshot copy policy specifies the frequency and number of automatically created NetApp Snapshot copies. A NetApp Snapshot copy is a point-in-time file system image that has no performance impact and requires minimal storage. You can choose the default policy or none. You might choose none for transient data: for example, tempdb for Microsoft SQL Server.

    2. Protocol: Choose the protocol for the volume (NFS or CIFS) and then set the access control or permissions for the volume.

      If you choose CIFS and a server isn’t set up yet, then Cloud Manager prompts you to set up a CIFS server using either Active Directory or a workgroup.

      The following list describes fields for which you might need guidance:

      Field Description

      Access Control

      An NFS export policy defines the clients in the subnet that can access the volume. By default, Cloud Manager enters a value that provides access to all instances in the subnet.

      Permissions and Users/Groups

      These fields enable you to control the level of access to an SMB share for users and groups (also called access control lists or ACLs). You can specify local or domain Windows users or groups, or UNIX users or groups. If you specify a domain Windows user name, you must include the user’s domain using the format domain\username.

    3. Usage Profile: Choose whether to enable or disable storage efficiency features on the volume.

      ONTAP includes several storage efficiency features that can reduce the total amount of storage that you need. NetApp storage efficiency features provide the following benefits:

      Thin provisioning

      Presents more logical storage to hosts or users than you actually have in your physical storage pool. Instead of preallocating storage space, storage space is allocated dynamically to each volume as data is written.

      Deduplication

      Improves efficiency by locating identical blocks of data and replacing them with references to a single shared block. This technique reduces storage capacity requirements by eliminating redundant blocks of data that reside in the same volume.

      Compression

      Reduces the physical capacity required to store data by compressing data within a volume on primary, secondary, and archive storage.

    4. Review: Review details about the volume and then click Add.

Creating volumes from templates

If your organization has created on-premises ONTAP volume templates so you can deploy volumes that are optimized for the workload requirements for certain applications, follow the steps in this section.

The template should make your job easier because certain volume parameters will already be defined in the template, such as disk type, size, protocol, snapshot policy, and more. When a parameter is already predefined, you can just skip to the next volume parameter.

Note You can only create NFS or CIFS volumes when using templates.
Steps
  1. On the Canvas page, click the name of the on-premises ONTAP system on which you want to provision a volume.

  2. Click screenshot gallery options > Add Volume From Template.

  3. In the Select Template page, select the template that you want to use to create the volume and click Next.

    The Define Parameters page is displayed.

    Note: You can click the checkbox Show read-only parameters to show all the fields that have been locked by the template if you want to see the values for those parameters. By default these predefined fields are hidden and only the fields you need to complete are shown.

  4. In the Context area, the Working Environment is filled in with the name of the working environment you started with. You need to select the Storage VM and Aggregate where the volume will be created.

  5. Add values for all of the parameters that are not hard-coded from the template. See creating volumes for details about all the parameters you need to complete to deploy an on-prem ONTAP volume.

  6. Click Run Template after you have defined all the parameters needed for this volume.

Result

Cloud Manager provisions the volume and displays a page so that you can see the progress.

Then the new volume is added to the working environment.

Additionally, if any secondary action is implemented in the template, for example, enabling Cloud Backup on the volume, that action is also performed.

After you finish

If you provisioned a CIFS share, give users or groups permissions to the files and folders and verify that those users can access the share and create a file.

Replicating data

You can replicate data between Cloud Volumes ONTAP systems and ONTAP clusters by choosing a one-time data replication, which can help you move data to and from the cloud, or a recurring schedule, which can help with disaster recovery or long-term retention.

Backing up data

You can back up data from your on-premises ONTAP system to low-cost object storage in the cloud by using Cloud Backup. This service provides backup and restore capabilities for protection and long-term archive of your on-prem and cloud data.

Scan, map, and classify your data

Cloud Data Sense can scan your corporate on-premises clusters to map and classify data, and to identify private information. This can help reduce your security and compliance risk, decrease storage costs, and assist with your data migration projects.

Tiering data to the cloud

Extend your data center to the cloud by automatically tiering inactive data from ONTAP clusters to object storage using Cloud Tiering.
