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 on page 18).
NOTE:
The restrictions outlined in “One-to-one configuration” on page 17 also apply to consolidated
configurations.
When setting up a consolidated DR site configuration (see Figure 3 on page 19), consider the following:
• P6000 Cluster Extension uses the unit of DR groups as the failover unit. This means all vdisks or
members of a DR group will be failed over if the cluster software moves disk access from one
cluster node to another.
• P6000 Cluster Extension does not directly support managed sets. However, applications that
consist of more than one DR group in one or more P6000/EVA storage systems can be supported
by P6000 Continuous Access as managed sets.
• If necessary, you can configure managed sets by creating P6000 Cluster Extension resources that
include the DR groups included in the managed set and configuring them in the same application
service group (cluster group).
