DR Test

Yes exactly, could you please explain how they configured and how it work.

Thanks in advance.

So you are replicating data between R1 and R2 and you have multiple BCV hanging off the R2?

i think it's a better question for you, why did you configure it like that ? What is the business requirement ?

I recently joined in this organization. they configured like this for the array which is used for only Production Servers.

I have seen organizations do that.  In my experience they roll multiple BCV's against a restartable copy of the data so that if they experience corruption they can minimize the amount of time they roll-back to.  That was usually done on the source array though not the target.

Another option is that if you have a D/R test you can come up against one of the BCV copies while still maintaining a "GOLD" copy on the other set of BCV's. 

You may want to talk with your EMC account team that hopefully helped in designing what you have so they could shed some light on what you have.

Hello,

What is the configuration srdf/S or srdf/A ???

Probably the reason for BCV split instead of R1, R2 is they do not want to do the real DR everytime they do DR test. they just need to know that everything is ok when real DR occurs. so if the BCV split and sync works fine during DR Test they assume everything is ok. Lot of organisation do that as DR test.
