SAN performance overview
Performance monitoring provides details about the quantity of traffic and errors that a specific port
or device generates on the fabric over a specific time. You can also use performance monitoring to
indicate the devices that create the most traffic and identify the ports that are most congested.
Performance monitoring allows you to monitor your SAN using the following methods (requires a
Licensed version):
• Display the connections which are using the most bandwidth on the selected device or one of
the F_Ports on the device with a feature called Top Talkers.
• Gather and display real-time performance data (Switch Ports - FC, Switch Ports - GE, Switch
Ports - 10 GE, ISL Ports, E_Port Trunks, end-to-end Monitors, FCIP Tunnels, device Ports,
managed HBA Ports, and managed CNA Ports).
The Professional version only allows you to monitor your SAN by gathering and displaying
real-time performance data (Switch Ports - FC, Switch Ports - GE, Switch Ports - 10GE, ISL
Ports, E_Port Trunks, end-to-end Monitors, FCIP Tunnels, device Ports, managed HBA Ports,
managed CNA Ports).
• Persist and display historical performance data (Switch Ports - FC ports, ISL ports, device
Ports, FCIP tunnels, SFP, and Switch Ports - 10 GE Ports) for selected fabrics or the entire SAN.
• Create custom port and time data filters for historical performance data that can be saved as a
favorite.
• Support end-to-end monitors for real-time and historical performance data.
• Enforce user-defined performance thresholds and notification when thresholds are exceeded.
• Display “insufficient resources” message when the is busy and you request performance
statistics.
• Display percentage utilization for FC and FCIP links.
