RDR is Regional Disaster Recovery, where we have 3 OCP clusters tied together.
1st is hub where RHACM is installed which manages other 2 OCP clusters using submariner add-ons.
2nd and 3rd are where ODF is installed and they are connected via submariner connectivity and are used in case of any disaster to perform failover/relocate operations between them to recover and ensure business continuity with min. data loss and min. application downtime. 

At a time, one of the managed clusters where ODF is installed works as primary cluster where IOs are run, and the other works as secondary or stand by cluster where the data is being replicated all the time and can be used in case of any such event.

Milind, PTAL.

Milind, did you get a chance to take a look?

Milind, this question should be asked from the ceph build team (Ken Dryer). We just use the tag provided by the ceph build team to build ODF.
