Performance Monitoring

The Performance Monitor displays real-time performance statistics for logical drives and physical drives. The

vertical scale adjusts dynamically to accommodate the statistical data.

Because it reports performance in real-time, to see data in the monitor, there must be I/O data activity taking

place between the subsystem and the Host.

To monitor performance:

1. Click the Administrative Tools icon.

2. Click the Performance Monitoring icon.

3. Click the Information tab for aggregated statistics; or choose the Read/Write tab to view specic Read

and Write performances separately.

4. Under Logical Drive, choose the metric you want to see from the Measurement drop-down menu.

5. Check the boxes for the logical drives you want to see.
