Modifying a Live Volume Datastore
Modify the settings of an existing Live Volume datastore.
Steps
1. Select the datastore that is being replicated.
2. Select Actions > Dell Storage Actions > Replications/Live Volume > Edit Settings/Convert.
The Modify Replication or Live Volume wizard starts.
3. From the list of replications, select one to modify.
4. Click Next.
The Volume Settings page opens.
5. 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.

• Replication Type:
○ Live Volume, Asynchronous
○ Live Volume, Synchronous—High Availability
○ Live Volume, Synchronous—High Consistency
• QoS definition—Select a predefined QoS definition for the replication.
• Replicate Active Snapshot—Select this option to copy all writes from the active snapshot area of the volume. This option
cannot be disabled for synchronous replication.
