Editing Volume Settings

Edit the datastore settings to expand the datastore, change the volume Storage Profile or to select a different QoS Profile for the datastore.

1. Select a datastore.
2. Select Actions > All Dell Storage Actions > Edit Datastore.
   The Edit Datastore wizard opens to the Expand Datastore page.
3. Select a new size for the datastore, and click Next.
   The Volume Settings page opens.
4. Select the volume settings:
   • Storage Type—A Storage Type is a pool of storage with a single datapage size. The Storage Type is set at the disk folder level, and once set it cannot be changed without assistance from technical support. (This entry appears only if the preferences are set in Storage Center).
   • Storage Profile—A Storage Profile controls how the Storage Center manages volume data.
     • Recommended (All Tiers)—Select this option for most volumes. The Recommended profile allows the system to automatically progress data between and across all storage tiers based on the type of data and usage.
     • High Priority (Tier 1)—Select this option to force volume data to remain in tier 1 storage.
     • Medium Priority (Tier 2)—Select this option to force volume data to remain in tier 2 storage.
     • Low Priority (Tier 3)—Select this option to force volume data to remain in tier 3 storage.
   • Data Reduction Profile—Data Reduction uses compression and deduplication to decrease the amount of disk space that is used by volume data. Compression reduces the amount of space that is used by a volume by encoding data. Deduplication finds duplicate pages and removes them, conserving the disk space that would be used by additional copies. When deduplication is used, compression is also applied to a volume.
   • Cache Settings—Select or clear the Read Cache Enabled and Write Cache Enabled check boxes to set the default cache settings for the new volume.
   • Selected Volume QoS Profile—Accept the Volume QoS Profile Default or click Change it to select a different QoS Profile.
5. Select a Snapshot Profile for the volume, and click Next.
6. Click Next.
   The Ready to Complete page opens.
7. Review the settings and click Finish to apply the new settings.
