Goran,
We are using both SRDF/A and Server Cloning Processes for replication. The process is fairly simple with the most of the coding/scripting effort . One of the Issues we've encounted is while the Clone process is running There is a very high amount of I/O Being Done as the Disk Frame level. Since a clone can only be done in the Same Frame level. This can cause Database Bottlenecks albeit for a small period of time .

We've Move to Data guard due to these issues. May i Ask what is the requirement . If Offloading Backups is the need. I've found Physical Dataguard to be better than EMC Cloning. SRDF/A is a different product set from EMC and it allows for between Frame/Datacenters replication. It is a fairly costly solution though. While Oracle will certify an Oracle Database Running on an EMC Frame. It will not certify a 3rd Part product.

The technology is called Split mirror and the EMC Product is Time Finder. Meta link Note Exploiting EMC Timefinder and Oracle Recovery Manager [ID 204719.1]

Hi all,

at the place where I work, management would like to implement EMC Replication (as we have EMC SAN's) for our databases between two Data Centers instead of DataGuard for certain DB-systems.
According to EMC sales, the process is certified by Oracle although I didn't find any reference on Metalink (could be also, I didn't search it well). If someone (out there ;-) ) is already using it, I would appreciate if you could tell me your experiences and possible pitfalls regarding implementation.

Best Regards,
Goran
