Save storage space using compression, compaction, and deduplication

Contributors netapp-thomi netapp-aherbin Download PDF of this topic

For volumes on non-AFF clusters, you can run deduplication, data compression, and data compaction together or independently to achieve optimal space savings.

  • Deduplication eliminates duplicate data blocks.

  • Data compression compresses the data blocks to reduce the amount of physical storage that is required.

  • Data compaction stores more data in less space to increase storage efficiency.

These tasks are supported for volumes on non-AFF clusters. Beginning with ONTAP 9.2, all inline storage efficiency features, such as inline deduplication and inline compression, are enabled by default on AFF volumes.
Steps
  1. Click Storage > Volumes.

  2. Next to the name of the volume for which you want to save storage, click Menu choices icon.

  3. Click Edit and scroll to Storage Efficiency.

  4. Optional: If you want to enable background deduplication, ensure the checkbox is checked.

  5. Optional: If you want to enable background compression, specify the storage efficiency policy and ensure the checkbox is checked.

  6. Optional: If you want to enable inline compression, ensure the checkbox is checked.
