Forgot to answer your other question.  "Can we have 1 to 2 RP configuration (multiple copy) from right side to left side in case of idea 1 if the customer wants to do that?"  Not sure if I fully understand but if you are replicating a LUN from the right side to the top left side you can't replicate that same LUN to the bottom left side. A LUN can belong to one cluster. And you have to have the same number of RPAs across the sites. Site 1 has 2 RPAs then site 2 has to have 2 RPAs. YOu can't have 4 RPAs at site 1 and 2 RPAs at site 2 for example.
Hello,  Which one is best practice or recommended to add another RP series to an existing RP series between the following idea 1 and idea 2 by EMC?  I assume the both ideas can be implemented and we don't need to do initial sync for the existing RP series after the RP appliance is upgraded in the idea 2 because the RPA is cluster configured. Is that right?  I assume the idea 1 is good from reliability perspective because one series can continue the copying after another series fails. And I assume the idea 2 is good from operating expense perspective. By the way, Can we have 1 to 2 RP configuration (multiple copy) from right side to left side in case of idea 1 if the customer wants to do that?  The existing environment has VPLEX both in idea 1 & idea 2 even though I haven't heard where it is.  Idea 1 [IMAGE]  Idea 2 [IMAGE]  Best regards, Hiroki
Which one is best practice as RP multi site system?
