Peer-to-Peer Remote Copy (PPRC)
PPRC is a hardware solution which provides rapid and
accurate disaster recovery as well as a solution to workload movement
and device migration. Updates made on the primary DASD volumes are
synchronously shadowed to the secondary DASD volumes. The local storage
subsystem and the remote storage subsystem are connected through a
communications link called a PPRC path. You can use one of the following
protocols to copy data using PPRC:
- ESCON
- Fibre Channel Protocol
Requirement: Fibre Channel Protocol is supported only on ESS Model 800 with the appropriate licensed internal code (LIC) level and the PPRC Version 2 feature enabled.
