Running the Test
Click the Green Flag on the top button bar to start the test. Select the “Results
Display” tab in the IOMeter window. Drag the slider under “Update
Frequency (seconds)” over to 1 or 2 seconds.
Interpreting Results
Use the Windows Performance Monitor to validate the results that IOMeter
reports. By default, IOMeter reports in Megabytes per second and the
Windows Performance Monitor reports in Bytes per second. To convert the
IOMeter MB/sec to Bytes/sec, multiply by 1024 and then again by 1024.
Access Specifications to Run
Run the following access specifications to emulate different use scenarios and
record your results. The typical results listed below were run on a Windows
2003 Server with Service Pack 2. The SAN was running SAN/iQ 7.0 with VIP
load balancing enabled (no DSM). The switches had flow control enabled, but
jumbo frames were not.
