Figure 91 Example showing throughput of two volumes
Activity generated by a specific server example
This example shows the total IOPS and throughput generated by the server (ExchServer-1) on two
volumes.

Planning for SAN improvements
If you have questions such as these about planning for SAN improvements, the Performance Monitor
can help:
• Would enabling NIC bonding on the storage systems improve performance?
• Is the load between two clusters balanced? If not, what should I do?
• I have budget to purchase two new storage systems.
Which volumes should I move to them to improve performance?◦
◦ Which cluster should I add them to?
The Performance Monitor can let you see the following:
• Network utilization to determine if NIC bonding on the storage systems could improve
performance
• Load comparison of two clusters
• Load comparison of two volumes
Network utilization to determine if NIC bonding could improve performance example
This example shows the network utilization of three storage systems. You can see that Denver-1
averages more than 79% utilization. You can increase the networking capacity available to that
storage system by enabling NIC bonding on the storage system. You can also spread the load out
across the storage systems using iSCSI load balancing.
