HP StorageWorks XP24000/XP20000 Performance Control User's Guide (T5214-96047, December 2008)

4 Performance Control Windows
This chapter describes the Performance Control windows. The remaining sections describe procedures
for monitoring performance and setting the upper limits and thresholds for I/O rates and transfer
rates.
The Performance Control window has two tabs: Port tab and WWN tab. If one-to-one connections
are established between Host Bus Adapters (HBAs) and ports, use the Port tab. If many-to-many
connections are established between HBAs and ports, use the WWN tab. For operations using these
tabs, see “If Many-to-Many Connections Link HBAs and Ports” on page 30.
If the user type of your user ID is storage partition administrator, you cannot use XP Performance
Control. For details on the limitations when you are using Performance Monitor logged in as a storage
partition administrator, see the HP StorageWorks XP24000/XP20000 Performance Monitor User's
Guide.
This chapter describes these tabs in the Performance Control window.

The Port tab lets you set the limit on the performance of non-prioritized ports and set the threshold on
