WWN Tab of the Performance Monitor Window
When you click Go, Performance Manager and then Performance
Management on the menu bar of the Storage Navigator main window,
Performance Monitor starts and the Performance Management window is
active. The Performance Management window includes the WWN tab,
where you view statistics (I/O rates, transfer rates, and average response
time) about traffic between host bus adapters in the hosts and ports on the
storage system.
Caution: The WWN tab is unavailable if Server Priority Manager is not
enabled.
A WWN (Worldwide Name) is a 16-digit hexadecimal number used as the
unique identifier for a host bus adapter. Host bus adapters are contained in
hosts and serve as ports for connecting the hosts and the storage system. One
WWN represents one host bus adapter.
For details on how to use this window, see Monitoring Paths between Host Bus
Adapters and Ports.
