Multiple Target Peer-to-Peer Remote Copy (MT-PPRC) was introduced with IBM® System Storage® DS8870 Version 7 Release 4 (License Machine Code 7.7.40.xx.xx).
MT-PPRC provides the capability to have two PPRC relationships on a single primary volume. With this enhancement, there can be another target available to provide additional data protection to act as a backup if a disaster occurs.
This IBM Redpaper™ publication provides practical information about the characteristics and functions of the IBM DS8000® Multiple Target Peer-to-Peer Remote Copy (MT-PPRC). The paper includes scenarios that illustrate the implementation and use of different topologies, as well as enhanced migration scenarios.
