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.
