1 Overview of HP StorageWorks XP
Performance Control Software
Performance Monitor provides usage statistics about physical hard disk drive, volumes, processors,
or other resources in your storage system. Performance Monitor also provides statistics about workloads
on disk drives and traffic between hosts and the storage system. The Auto LUN 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 Guide.
Figure 1 illustrates and simplifies the performance management process.
