Components

To use Performance Monitor, you need:
The storage system
The Performance Monitor program products (Performance Monitor is required. XP Auto LUN is
optional)
A WWW client computer connected to the storage system via LAN
To use Performance Monitor, you must use the WWW client computer to log on to the SVP. When
you are logged on, the HP StorageWorks Remote Web Console program, which is a Java application
program, automatically downloads the applet the to the WWW client computer. You can perform
Performance Monitor operations in the Remote Web Console window.
For details about requirements for WWW client computers, see HP StorageWorks XP24000/XP20000
Remote Web Console User Guide.
CAUTION:
If Performance Monitor is not enabled, you cannot use XP Auto LUN.
Performance management operations (Performance Monitor and XP Auto LUN) involve the collection
of large amounts of monitoring data. This requires considerable web client computer memory. It
is therefore recommended that you exit the Remote Web Console program when not conducting
performance management operations, to release system memory when not conducting performance
management operations.
