System Manager Classic

You can use ONTAP System Manager classic (available in ONTAP 9.7 and earlier) to enable storage efficiency and to configure both deduplication and data compression or only deduplication on a volume to save storage space. If you have not enabled storage efficiency when you created the volume, you can do so later by editing the volume.

Before you begin

  • The volume must be online.

  • If you want to use a policy-based deduplication schedule, you must have created an efficiency policy.

About this task

  • You can enable background compression only if you have enabled background deduplication.

  • You can enable inline compression and inline deduplication with or without enabling background compression and background deduplication, respectively.

  • You can enable inline deduplication only on volumes that are contained by an aggregate with All Flash Optimized personality and on volumes that are contained by a Flash Pool aggregate.

  • Beginning with System Manager 9.6, editing storage efficiency is supported for FlexGroup DP volumes.

Steps

  1. Click Storage > Volumes.

  2. From the drop-down menu in the SVM field, select All SVMs.

  3. Select the volume for which you want to enable storage efficiency, and then click Edit.

  4. In the Edit Volume dialog box, click Storage Efficiency.

  5. Select the Background Deduplication check box.

  6. Select one of the following methods to run deduplication:

    Based on a storage efficiency policy

    1. Ensure that the Policy based option is selected.

    2. Click Choose, and then select a storage efficiency policy.

    3. Click OK.

    When required

    Select the On-demand option.

  7. Select the Background Compression check box to enable background compression.

    You cannot enable background compression for a volume that is contained by an aggregate with All Flash Optimized personality.

  8. Select the Inline Compression check box to compress data while it is being written to the volume.

    By default, inline compression is enabled on volumes that are contained by an aggregate with All Flash Optimized personality.

  9. Select the Inline Deduplication check box to run deduplication before data is written to the disk.

    By default, inline deduplication is enabled on volumes that are contained by an aggregate with All Flash Optimized personality.

  10. Click Save and Close.
