SRDF has a lot of features that are valuable for us in the enhanced DR solution. The feature of taking snapshots from the replicated volumes has allowed us to use them for DR testing to validate the application consistent point of recovery. Device groups and replication groups help us to group the replicated volumes by DR recovery tier. Integration with VMware SRM vis Dell EMC SRDF SRA adapter has enabled us to perform automated recovery testing. The rest of the open systems platforms have automated the recovery process.
