Hello Alshehri,

It is best to open a support case, as there are many factors that will need to be checked before we can recommend the best settings to use.

Hello Alshehri,

With the distance that you have between sites, you will want to do async.  To do sync it is best if both sites are less than 10km apart.  You are going to want the max amount of speed you can get for going 1000km.  I would suggest nothing less than 4gb connection, but that also depends on your RPA.

Thanks Sam , actually I am looking here for building a new DR site and I would like to identify what is best speed link needed the achieve the two options sync & asycn replication .
