IBM MetroMirror
(PPRC)
Enginuity level 5772 enables the Symmetrix system to support native
IBM MetroMirror Peer-to-Peer Remote Copy (PPRC) commands
through a Symmetrix feature called Compatible Peer. PPRC is the
remote copying solution available with IBM storage systems
Figure 54 on page 236. Enginuity supports PPRC version 1,
architecture level 2 CGROUP FREEZE/RUN functionality. Enginuity
level 5771 adds support for PPRC version 1, architectural levels 3 and
4 Hyper-Swap support, including failover/failback functionality. As
a result, Symmetrix systems will support these capabilities in IBM’s
Geographically Dispersed Parallel Sysplex (GDPS) solution.
Compatible Peer is available on Symmetrix systems with connections
to ESCON or FICON hosts.
Note: Contact your local EMC representative for specific details regarding
your Symmetrix system's support for Compatible Peer.
