Overview of Command View XP Advanced Edition Device Manager 14
• Web Client. Device Manager Web Client provides two types of user interfaces, an HTML GUI and a
Java™ GUI, for Device Manager functions. Web Client communicates with and runs as a client of the
Device Manager server.
The HTML GUI is a browser-based application that can be accessed from Web browsers. This GUI
provides the windows and dialog boxes for features other than the storage subsystem management
and user management features.
The Java™ GUI is a stand-alone Java™-based application which is deployed using the Java™ Web
Start software. This GUI provides the windows and dialog boxes for the storage subsystem and user
management features.
This document describes how to install and configure the Java™ environment (see Chapter 3 ).
• Command Line Interface (CLI). CLI allows you to perform Device Manager operations by issuing
commands from the system command line prompt. CLI communicates with and runs as a client of the
Device Manager server.
NOTE: For further information on CLI, refer to the HP StorageWorks Command View XP
Advanced Edition Device Manager CLI User Guide.
• Third-party applications. Device Manager supports third-party applications by providing an application
program interface (API) that developers can use to interface with the Device Manager server.
• Agent (recommended, optional). The Device Manager agent runs on a host that is attached to one or
more storage subsystems, collects data on the configuration and utilization of the attached storage, and
sends this information to the Device Manager server. The Device Manager clients display this information
for the user when it is available on the server. For more information, refer to the HP StorageWorks
Command View XP Advanced Edition Device Manager Agent Installation Guide.

1-4 Important Terms and Concepts
Device Manager users should be familiar with the following terms and concepts.
• Array (parity) group: A set of hard disk drives (HDDs) which have the same capacity and are treated as
one RAID unit. An array group contains user data and parity information, which ensures user data
integrity in the event of a disk drive failure in the array group.
• Business Copy XP: The Business Copy XP feature enables the user to make backup copies of volumes
in the same storage subsystem. For details, refer to the Business Copy XP manual.
• Cache Partition Manager: Provides the cache logical partition function. For more information, see section
2-3-1 .
• Channel adapter/port controller: A fibre-channel adapter in the storage subsystem that is equipped with
one or more ports to establish connection with the host. For StorageWorks XP Disk Array, it is referred to
as the channel adapter (CHA).
• Command device: An LU used exclusively for communicating with the RAID Manager software on the
host to control copy operations.
