Figure 32-3 GDPS 3-site configuration with GDPS/PPRC and GDPS/XRC
The same primary volume for PPRC and XRC can be supported by two different GDPSs, a
GDPS/PPRC for metropolitan distance and Business Continuity, and a GDPS/XRC for
regional distance and Disaster Recovery.
The two mirroring technologies and GDPS implementations work independently of each
other, yet provide the synergy of a common management scheme and common skills.
More details on GDPS 3-site configurations can be obtained from your IBM GDPS
representative.
