HP P6000 Cluster Extension Software Administrator Guide (5697-2274, November 2012)

NOTE: For complete information on which write modes are supported on each version of
controller software, see the HP Enterprise Virtual Array Compatibility Reference.
P6000 Cluster Extension supports P6000 Continuous Access in synchronous replication mode
and enhanced asynchronous replication mode in the following configurations:
Switched FC connection (dual-fabric intersite links)
FC to DWDM networks, via FC switches
FC over IP networks, via FC switches as shown in the HP P6000 Continuous Access
Implementation Guide
The P6000 Continuous Access links must have redundant, separately routed links for each
fabric. The cluster network must have redundant, separately routed links. However, cluster
networks and P6000 Continuous Access can share the same links if the link technology is
protocol independent (for example, WDM) or if the FC protocol is transformed into IP.
Figure 2 One-to-one configuration
Consolidated DR site configuration
P6000 Cluster Extension supports configurations that have a single P6000/EVA storage system
in the disaster recovery data center and up to two source P6000/EVA storage systems (the logical
configuration must be a one-to-one configuration as shown in Figure 2 (page 9)).
NOTE: The restrictions outlined in One-to-one configuration (page 8) also apply to consolidated
configurations.
