How CA impacts on EVA performance

Hi,

My customer wants to know how big the performance impact is when CA is enabled on EVA8000.
Now customer wants to disable it so he can make some performance measurements. Btw it is a SAP BI productive Linux environment.

My question is:
Does anybody knows the performance impact and
is it possible to disable CA without caching the data on the primary Storage?

Any hint would be very appreciated!

Thanks
M.Grande

>>> Does anybody knows the performance impact

It depends of the ammount of I/O, the distance, the link bandwidth and the replication mode.

>> Is it possible to disable CA without caching the data on the primary Storage?

You will have to break the DR Group.

Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?
