HP StorageWorks XP Replication Monitor software installation and configuration guide (T1784-96008, November 2006)

Designing systems 15
For a mainframe system:
• One of the sites must have a management server on which the XP Replication Monitor server is
installed. Other sites do not need any management servers.
1-2-1 Software components
The following sections provide an overview of the functions of the software components, separated into open
system and mainframe system descriptions.
1-2-1-1 Software components (open system)
XP Replication Monitor server
The XP Replication Monitor server is the core component of XP Replication Monitor software. The XP
Replication Monitor server maintains its own database containing information collected by the Device
Manager server and copy pair information collected by the XP Replication Monitor agent, and provides this
information to the user through the web client. The XP Replication Monitor server also updates this database
by collecting the most recent information when a user requests an update or when a periodic update is
performed.
Device Manager server
The Device Manager server maintains a database of information collected by the Device Manager agent
and by this server directly from the storage subsystems, and provides this information to the XP Replication
Monitor server. The Device Manager server also updates this database by collecting the most recent
information when a user requests an update or when a periodic update is performed.
Device Manager agent
The Device Manager agent on a host provides information about that host to the Device Manager server.
The Device Manager agent on a pair management server collects configuration information on the copy
pairs being managed by the pair management server, and provides this information to the XP Replication
Monitor server. Based on instructions from the Device Manager server, the Device Manager agent also
passes along pair status change instructions to RAID Manager XP.
XP Replication Monitor agent
The XP Replication Monitor agent collects status information on the copy pairs that are managed by its pair
management server, and provides this information to the XP Replication Monitor server.
RAID Manager XP
RAID Manager XP collects information on its managed copy pairs, and provides this information to the XP
Replication Monitor agent and the Device Manager agent. RAID Manager XP also passes along pair status
change instructions to the storage subsystem.
1-2-1-2 Software components (mainframe system)
XP Replication Monitor server
The XP Replication Monitor server is the core component of XP Replication Monitor software.
The XP Replication Monitor server maintains its own database of information that it collects from the
Business Continuity Manager on the hosts, and provides this information to the user through the web client.
The XP Replication Monitor server also updates this database by collecting the most recent information
when a user requests an update or when a periodic update is performed.
Device Manager server
The Device Manager server is required when the XP Replication Monitor server is installed. However the
Device Manager server has no functionality for mainframe systems.
Business Continuity Manager
Business Continuity Manager collects information about the copy pairs it manages and provides this
information to the XP Replication Monitor server.

The following provides a functional overview of and requirements for the hardware components of a XP
Replication Monitor system.
