The most technically correct answer to your questions is: it depends.
We used to do the controller to controller method (IBM's PPRC), but have
recently implemented IBM's XRC. XRC requires a live operating system
running at the remote site to manage the replication.
Just to complement: XRC requires datamover. It need not be neither
remote, nor separate system.
