Congestion Weights
The parameters shown in Table 3-27 control the weight to use for each individual
counter when computing congestion, which are combined to form the
Congestion count. Integrity errors can also cause congestion.
• XmitDiscard is available for all devices.
• XmitCongestionPct10 and XmitInefficiencyPct10 are available for
QLogic QDR switches only. This is based on the deepest Virtual Lanes
queue depth.
• XmitWaitCongestionPct10 and XmitWaitInefficiencyPct10
available for QLogic QDR and DDR Host Channel Adapters only. This is
based on the time the link was idle because none of the Virtual Lanes that
had data to transmit had any credits.
