Modifying the capacity saving setting for volumes

Storage Advisor Embedded User Guide

Part Number

You can modify the capacity saving setting (deduplication and compression) for volumes.

If you change the settings while capacity saving is enabled, rehydrating the data might take some time.

The capacity saving function for VSP E1090 and VSP E1090H storage systems includes a compression accelerator. We recommend using compression acceleration because it allows you to reduce the load that data compression places on the storage system. Note that changing the capacity savings compression method when using compression acceleration means that the new method is applied to all volume data and the processing takes some time.

For details on the capacity saving function, see the Provisioning Guide.

  • Identify the server name.
  • Identify the volume name.
  • If the planned changes can impact the free space on the pool, check the current amount of free space.
