The first step is to download Iometer to the VM where we want to run the tests:

1. Download the appropriate executable from http://www.iometer.org/doc/downloads.html.
2. Once downloaded, run the Iometer.exe file.

Iometer requires some setup before it can be started. For these tests, I created a second 10 GB hard drive labeled E: on the VM where the Iometer tests will be performed. By default, Iometer creates one manager (with the same name as your VM) and four workers (Worker 1 through 4). We will run the tests with the defaults, but you can create additional managers and workers depending on your testing needs:

1. Click on the plus sign next to the manager to see the four default workers.
2. You can add or remove workers as required.

3. For each of the workers, do the following:
   1. Click on the worker.
   2. Click on the Disk Targets tab and select the drive you want to target:

1. 3. Click on the Access Specifications tab and add the All in one (at the bottom) option to Assigned Access Specifications. If you have a specific block size, read/write ratio, or randomness that you want to test, select one of the specifications from the list. You can also click on New to create your own custom specification:

4. Click back on the manager in the Topology section.
5. Click on the Results Display tab and change Update Frequency to 5.
6. Click on the Start Tests button with the green flag icon.
7. Select a location for the results file from the pop-up window.
8. Wait for the test files to be created.
9. When the test is run, you will see the results in the Results Display tab.

When the test is running, Iometer will look something like this:
