Fairness and Prioritization
The concept of "fairness" is based on the principle of ensuring fair device access and communication 
across all devices in a storage system. The switch incorporates fairness and prioritization through 
InSpeed technology and Automatic Trunking and Load Balancing functionality. In cooperation with each 
other, these features ensure even and equal access through multiple links fairly–effectively multiplying 
bandwidth.
Device prioritization can be achieved using Load Balancing and assigning only a specific device port to 
a particular cascade. This ensures that a specific device will always have a dedicated trunk.

The Emulex Model 375 SAN Storage Switch provides several options for monitoring the switch status 
and port information. This section describes how to view switch status, the event log, port information 
and utilization, and port diagnostics.
Viewing Switch Status
The Web Manager’s home page is the Switch Information page. This page is displayed first when the 
Web Manager is opened and shows general switch information, including switch status, fan and power 
supply operational indicators, and port health and utilization.
This page continually refreshes to guarantee that the most current switch status is displayed. To return 
to this page at any time, click the Storage Switch menu item.
