IBM  PPRC Peer-to-Peer Remote Copy (PPRC) is an ESS function that allows the shadowing of application system data from one site (usually called the application site) to a second site (called the recovery site). The logical volumes that hold the data in the ESS at the application site are called primary volumes, and the corresponding logical volumes that hold the mirrored data at the recovery site are called secondary volumes.
PPRC Extended Distance operation (PPRC-XD): This operates non-synchronously and can be used over continental distances, with excellent application performance. When implementing this solution over long distances, you need to use channel extenders.

EMC SRDF protects information and provides comprehensive business continuity in the face of both planned and unplanned outages. This online, host-independent, mirrored data solution duplicates your production site data on one or more physically separate target Symmetrix systems. Systems can be across the room, across the globe, or anywhere in between. 

Hitachi Asynchronous Remote Copy (HARC) -  HARC provides asynchronous remote copy for S/390 data from one Lightning9900 to another or to a 7700E over channel extenders available from CNT andINRANGE. Records are time stamped to ensure that data is not lost or out oforder. Since the transmission is asynchronous, data can be transmitted overunlimited distances.
