Yes this is truly good point to use Storage solution when we need to replicate
Apps to DR. I am trying to see as what is recommended or used in major
environment as like we are using Dataguard or Storage Based solution for
Databases. Any pros and cons of comparsion. Also it is true that the
environment is 11g R2 and same OS and Db version on both side as well as
Server configuration to make it true DR to support all primary Load on DR.
Never used or worked much with Storage based DR for Database and so trying to
look for some comparision.

Each storage vendor does provide documentation on DR implementation via Storage
Replication.
Â
For example :Â Hitachi TrueCopy :
              Â
http://www.hds.com/products/storage-software/truecopy-remote-replication.html?_p=v
or          Â
http://www.hds.com/assets/pdf/hitachi-storage-supports-oracle-databases-solution-profile.pdf
Â
DataGuard is Oracle Database Specific.
If you need to provide DR support for Application Servers (and who doesnâ??t
??), Input (Loader) files, Output (logs, reports etc)   you would still
look at Storage Based Replication.

I am not much familiar with actual way the storage replication works. Surely
want to see what is benefit of Storage based replication and how we are
synching it to come close to realtime. Requirement is to have least downtime in
case of site loss and my mistake earlier to say No downtime.
