What can I learn about my SAN?

If you have questions such as these about your SAN, the Performance Monitor can help:
• What kind of load is the SAN under right now?
• How much more load can be added to an existing cluster?
• What is the impact of my nightly backups on the SAN?
• I think the SAN is idle, but the drive lights are blinking a lot. What is causing that?
Generally, the Performance Monitor can help you determine:
• Current SAN activities
• Workload characterization
• Fault isolation

Current SAN activities example

This example shows that the Denver cluster is handling an average of more than 747 IOPS with an
average throughput of more than 6 million bytes per second and an average queue depth of 31.76.

Workload characterization example

This example lets you analyze the workload generated by a server (ExchServer-1) including IOPS
reads, writes, and total and the average IO size.
