Current San Activities Example; Workload Characterization Example; Fault Isolation Example - HP StoreVirtual 4000 User Manual

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.
Figure 87 Example showing overview of cluster activity

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.

Fault isolation example

This example shows that the Denver- 1 storage system (dotted line pegged at the top of the graph)
has a much higher IO read latency than the Denver-3 storage system. Such a large difference may
be due to a RAID rebuild on Denver- 1 . To improve the latency, you can lower the rebuild rate.
