Critical FCIP Performance settings The following four parameters are critical to ensure optimal performance of the MPX200. Configuring the FCIP Route to match the actual link characteristics is the only way to ensure the best utilization of the available bandwidth. • Bandwidth per route: do not set the bandwidth setting above the guaranteed bandwidth of the link for each FCIP route. • TCP Windows size • TCP Windows scaling factor: Use the recommended setting documented in this guide for the actual bandwidth and RTT of the link. • For recommendations on setting compression see IP performance tuning, page 131. NOTE: HP recommends that you accept the default settings for TCP Port and GE Port Speed. If you need to change the port speed, select Full Duplex mode; Half Duplex mode is not supported. Configure the FCIP routes using the CLI For each MPX200, configure the FCIP route information as follows: MPX200 (admin) #> fciproute add A list of attributes with formatting and current values will follow. Enter a new value or simply press the ENTER key to accept the current value. If you wish to terminate this process before reaching the end of the list press 'q' or 'Q' and the ENTER key to do so. WARNING: The following command might cause a loss of connections to both GE ports.
