3 indicates that the warning threshold has been exceed at least 30% of the time or the exception threshold has been exceeded 10% of the time. This is a list of useful Brocade switch commands that will help you for. The ratings for the busiest port on each switch are rolled up to the switch level, so that if you look in the legend you will see ratings for several of the switches in bold and with ratings ranging between. The utilization data is aggregated at the switch level, so the average utilizations are pretty low. To remedy this, you can add a two-port FC target adapter to each controller, then rezone your FC switches so that 15 of your 30 hosts connect to one set of. In a MetroCluster configuration, these are the ports that connect the switch to the HBA initiators.

How to Troubleshoot and Resolve Port Utilization Issuesįigure 2 below shows a port utilization chart by switch. You must configure the non-E-ports on the FC switch. When these connectors do not have enough lanes to keep traffic flowing smoothly it can cause congestion and result in buffer credit shortages which can lead to performance delays.
You can think of the ISL’s as the connectors that link major freeways. These are called Inter-switch Links, or ISLs for short, and the port type for ISLs is ‘E’. In some Storage Area Network environments (SAN) there are switches that connect to other switches. Currently, 8 Gbit/sec is the most common host interface speed, although we are seeing storage connections and switch connections running 16 Gbit/sec.
