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.

MONITORING THE SWITCH

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.

Switch Information

Current status is provided for the following items.

Item Status Indicators

Switch Status • OK (green)–the switch unit is operating normally.

• Fault (red)–one or more of the ports has failed, the internal

temperature has exceeded acceptable levels, or another error has

occurred. Errors appear in the event log. The switch will continue to

operate; however, functionality may be impaired depending on the

event that triggered the error. Regardless of the cause, the switch

requires immediate attention.
