Congestion Management
5. Monitoring4. Congestion Management
Universal SAN congestion mitigation (USCM) is a feature that detects and
handles potential and actual congestion conditions in the SAN. A Fibre Channel
port can experience congestion due to various factors such as link instability,
credit stall, and over subscription. Both the HBA and the Fabric must support
USCM (and the feature must be turned on in the Fabric).
For all supported hardware, QConvergeConsole CLI displays state and statistics
related information associated with USCM.
From the Monitoring menu, select Congestion Management to view the USCM
Congestion Menu.
