5. Primary Data Collector at protected site 6. Remote Data Collector at recovery site
7. Storage Center at protected site 8. Storage Center at recovery site
In a conguration with a Storage Manager Remote Data Collector, locate the Remote Data Collector on the Recovery Site. This
conguration allows DR activation from the remote site when the Protected Site goes down. By design, the Storage Manager
Remote Data Collector is connected to the same Storage Centers as the Storage Manager Primary Data Collector.
Selecting the Snapshot Type to Use for SRM 5.x and 6.x Volume
Failover
The SRM Selectable Snapshot option determines whether the Active Snapshot (current volume data) or last frozen snapshot is
used when VMware Site Recovery Manager (SRM) initiates a failover or test failover. By default, the current, unfrozen state (Active
Snapshot) of the volume is used.
Limitations for Selecting the Snapshot Type for SRM Failover
In some situations, the SRM Selectable Snapshot conguration is ignored.

Change the Snapshot Type Used for SRM Volume Failover
Modify the SRM Selectable Snapshot option to change the snapshot type used for SRM volume failover.
1. In the top pane of the Dell Storage Manager Client, click Edit Data Collector Settings. The Edit Data Collector Settings dialog
box appears.
2. Click the Replication Settings tab.
3. From the SRM Selectable Snapshot drop-down menu, select one of the following options:
• Always use Active Snapshot: When selected, uses the current, unfrozen state of the data transferred to the destination
(Active Snapshot). This option is the default.
• Use Active Snapshot if Replicating Active Snapshot: When selected, uses the current, unfrozen state of the data (Active
Snapshot) only if Replicate Active Snapshot is enabled for the replication. If Replicate Active Snapshot is disabled, the last
frozen snapshot is used.
• Always use Last Frozen Snapshot: When selected, uses the most current snapshot that has been transferred to the
destination.
• Use Restore Point Settings: When selected, uses the settings that are congured for the restore point that corresponds to
the volume. If Use Active Snapshot is not selected within the restore point, the last frozen snapshot is used.
4. Click OK.
