algorithm of remote copy using some controllers

We are planning DR solution using remote copy SLD config with 4 controllers par 3par storage system.


I am wondering how algorithm 4 controllers use for loadbalancing.

Although I have heard it is round-robin, I want to know description much better.


1. Can each controllers have same performance not to lean specific controller ?

   (4 each controllers do remotecopy about same size volumes)


2. Can all controllers have same performance even if it is only one LUN for remotecopy ?

   (there are not some LUNs, 4 all controllers do remotecopy for only one LUN)


If you know that let me know, please ?
