Historical performance data

Performance should be enabled constantly to receive the necessary historical data required for a

meaningful report. The following options and features are available for obtaining historical

performance data:

• Collect historical performance data from the entire SAN or from a selected device.

NOTE

Virtual Fabric logical ISL ports are not included in performance collection.

• Persist data on every polling cycle (5 minutes).

• Store up to 3456 records (maximum) for each port. Most ports require 600 KB disk space;

however, the 256-Port Director requires 7GB disk space.

• Use the RRD (Round Robin Database) style aging scheme.

• Enable 5 minute, 30 minute, 2 hours and 1 day granularity.

• Support interpolation for up to 6 data points.

• Generate reports. For instructions on generating reports, refer to “Generating performance
