HP StorageWorks P9000 Replication Manager Software 7.1.1 Configuration Guide (TB584-96029, September 2011)

NOTE:
The configuration must always be refreshed when Replication Monitor is upgraded from v5.x to v7.x
Resource Limits
The maximum number of resources that can be managed by Replication Manager depends on the
memory heap size (Small, Medium, or Large). Set an appropriate memory heap size, depending on
the maximum number for each resource.
NOTE:
If you are using a Windows 32-bit environment, you cannot set “Large” as a memory heap size.
For details about how to increase the memory heap size, see the HP StorageWorks P9000 Command
View Advanced Edition Installation and Configuration Guide.
This section discusses the following:
• Maximum number of copy pairs, page 32
• Heap size in a mixed environment, page 33
• Number of copy pairs on open systems, page 33
• Log data and number of copy pairs, page 34
• Maximum number of LDEVs, page 32

NOTE:
In consideration of response time and memory usage, the maximum number of both open and

With respect to the number of mainframe pairs, the values in the table above are the maximum
number of copy pairs that Device Manager and Business Continuity Manager can manage.
Maximum number of LDEVs
The maximum number of manageable LDEVs depends on storage system specifications. The method
of determining the maximum number of manageable LDEVs differs between open systems and
Replication Manager system configurations and requirements32
