1 Overview of HP StorageWorks XP
Performance Control
XP Performance Control Software lets you obtain usage statistics about physical hard disk drive,
volumes, processors, or other resources in your storage system. Performance Monitor also lets you
obtain statistics about workloads on disk drives and traffic between hosts and the storage system. The
XP Auto LUN Software window displays a line graph indicating changes in the usage rates, workloads,
or traffic. You can view information in the window and analyze trends in disk I/Os and detect peak
I/O time. If system performance is poor, you can use information in the window to detect bottlenecks
in the system. For an overview, see the HP StorageWorks XP24000/XP20000 Performance Monitor
User's Guide.
Figure 1 illustrates and simplifies the performance management process.
