Steps

1. Select a datastore to replicate.

2. Select Actions > Dell Storage Actions > Replications/Live Volume > Add.

The Add Replica/Live Volume wizard starts.

3. Select the target (destination) Storage Center.

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.

6. Click Next.

The Replication Options page opens.

7. Select the replication settings:

• Replication Type:

○ Replication, Asynchronous

○ Replication, Synchronous—High Availability

○ Replication, 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.

• Deduplication—Select this option to copy only the changed portions of the snapshot history on the source volume, rather than

all data captured in each snapshot. Deduplication saves bandwidth but is more resource intensive for the Storage Center.

• Select the Replication Target Location.

8. Click Next.

The Ready to Complete page opens.

9. Click Finish.
