HP P9000 Replication Manager Software 7.3.1-00 Configuration Guide

NOTE:
In consideration of response time and memory usage, the maximum number of both open and
mainframe pairs that can be operated on by the Pair Configuration Wizard at one time is 1,000. In
the case of a mainframe system, when operating a copy group or consistency group that includes
25,000 or more copy pairs, specify Medium or Large for the memory size.
Number of copy pairs on open systems
If the number of copy pairs is 5,000 or more, edit the following Device Manager Agent properties
on the pair management server:
• server.agent.maxMemorySize in the server.properties file
• agent.rm.TimeOut in the agent.properties file
For details about how to edit the properties, see the chapter that describes the settings for using
Replication Manager to manage copy pairs in the HP P9000 Command View Advanced Edition Suite
Software Administrator Guide.
Number of copy pairs on mainframe systems
Among the number of copy pairs managed by Device Manager server and the number of copy pairs
managed by Business Continuity Manager Software, confirm that the larger number of copy pairs is
less than or equal to the value shown in Table 13.
Maximum number of LDEVs
The maximum number of manageable LDEVs is based on the total number of LDEVs in all managed
storage systems. The following table shows the maximum number of LDEVs.
In an environment where there are multiple sources for LDEV information acquisition, confirm that the
total number of LDEVs acquired from each information acquisition source is less than or equal to than
the maximum number. In an open system environment, when the memory heap size is Small or Medium,
the maximum number is the total number of LDEVs acquired from both the local and remote instances
of Device Manager. When the memory heap size is Large, the maximum number differs for the LDEVs
acquired from the local and remote instances of Device Manager.
