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 to indicate the
devices that create the most traffic and to identify the ports that are most congested.
Performance 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 - 10GE, ISL Ports, E Port Trunks, EE 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, EE Monitors, FCIP Tunnels, Device Ports, Managed HBA Ports, and
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.
NOTE
When the server is busy and you request performance statistics, an “insufficient resources”
message displays. Wait a while before you request the performance statistics again.
•
Display percentage utilization for FC and FCIP links.
•
Provide aging scheme.
The granularity varies depending on the configuration on the Server Management Console,
Performance Data Aging tab.
Option 1—2 years data with the following samples:
•
Raw samples for last 1 day
•
30 minutes granularity for last 3 days
•
2 hour granularity for last 30days
•
1 day granularity for last 2 years
Option 2—2 years data with the following samples:
•
Raw samples for last 8 days
•
1 day granularity for last 2 years
For more information, refer to “Defining the performance data aging interval” on page 309.
•
Provide enhanced performance reports.
