Conguring Data Reduction
Data reduction must be enabled at the system level and congured on a per NAS volume basis.
Enable or Disable Data Reduction on the FluidFS Cluster
Data reduction must be enabled at the system level before it will run on NAS volumes on which data reduction is enabled. To
minimize the impact of data reduction processing on system performance, schedule data reduction to run during o-peak times.
1. Click the Storage view and select a FluidFS cluster.
2. Click the File System tab.
3. Click NAS Volumes.
4. In the right pane, click Edit Settings. The Edit NAS Volume Settings dialog box appears.
5. Click Data Reduction in the vertical tabs.
