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

Designing systems 16
The machine on which the user, utilizing a web browser, runs the web client for XP Replication Monitor
software.
Management server
The machine on which the Device Manager server is installed.
The XP Replication Monitor server may or may not be installed on this machine.
Pair management server (open system)
The machine on which the Device Manager agent and RAID Manager XP are installed. This server is used
to manage and collect information on copy pairs defined in the RAID Manager XP configuration definition
file. You can collect configuration information and change the status of the copy pairs managed by a pair
management server.
The XP Replication Monitor agent may or may not be installed on this machine. If the XP Replication Monitor
agent is installed, you can collect status information on the copy pairs managed by the pair management
server.
The pair management server can also be used as a host (application server).
Pair management server (mainframe system)
In a mainframe system, a host (application server) on which Business Continuity Manager is installed is also
called a pair management server.
Host (open system)
The machine on which application programs are installed. It is also called an application server. The
Device Manager agent may or may not be installed on this machine. If the Device Manager agent is
installed, information about that host can be collected.
Host (mainframe system)
The machine on which application programs are installed. It is also called an application server.
A host on which Business Continuity Manager is installed is also called a pair management server.
Configuration information and pair status information on its managed copy pairs can be collected from a
host that is configured in this way.
Storage subsystem
An external storage device that is connected to the host. XP Replication Monitor software supports the same
storage subsystems that the Device Manager supports. For details, see the HP StorageWorks Command
View XP Advanced Edition software Device Manager server installation and configuration guide.
