The IPF is OS dependent, meaning that your OS must be supported.
If your OS is listed in the download section, you are good to go.
If it is not listed, send us your OS version to see if it can be supported.
2. Does the IPF load any 3rd party software to my computer?
No, just a small applet is installed to tabulate statistics of the IO streams, provided by built-in utilities.
Additional installation of standard tools may be required for Linux version only.
3. Will the IPF affect the performance of my computer when its running?
IPF does not impact performance while it is running.
Periodic tabulations can impact cpu usage to a small degree (1-2 % cpu usage).
4. Does the IPF take any personal data from my computer?
IPF does not take any personal or other data from your computer.
It only compiles statistics on the number and type of IO streams observed during the capture period.
These statistics are compiled into a binary file that is then uploaded to the testmyworkload.com site.
5. Is the IPF safe to use?
IPF has been proven to be safe and not to impact the target server.
IPF leverages off existing IO statistic tools that are usually contained within your OS kernel.
However, by using the IPF applet, you expressly release Calypso from any claims for damages arising from its use.
6. How big is an IPF capture file?
It depends on the duration and resolution of your capture and the type of activity that is run.
However, file size is usually less than 100MB for a 12-24 hour capture.
Capture files are further compressed and exported as a .zip file.
7. Where is the IPF capture file located?
IPF capture files are saved to the "Documents / My IO Captures" directory created on your target computer.
The exact pathway is displayed in the IOProfiler GUI that appears when profiling process has completed or was stopped.
8. How do I upload a capture?
After the capture is complete IOProfiler tool will suggest you to upload the data into TestMyWorkload automatically - just click the corresponding button and enter you login name.
Alternatively — just log on to the testmyworkload.com site and click upload capture.
Then point to the capture file (having .ipf extension) in your "Documents / My IO Captures" folder.
9. Is there any limit to the number of captures I can take?
You can take as many captures as you like.
However, when you use the Free applet, you are limited to the cumulative IO stream map and workload definition.
If you join the IPF Portal, you get additional features and other interesting information.
10. Is there a limit to how long I can set the duration of the capture?
You can set the duration for any length (e.g. 20 min, 60 min, 6 hrs, 12 hrs, 24 hrs, 3 days, 7 days)
However, as the duration increases, you should decrease the resolution.
Your file size will increase as the duration increases.
11. What is the impact of changing the 'resolution' setting for the capture?
The Resolution refers to the sample period over which IO statistics are averaged.
The finer the resolution, the larger the capture file.
It is recommended to use the default setting of 30 seconds.
You may decide to change resolution after you have captured and viewed several sessions.
12. Can I view a capture without uploading to the testmyworkload.com site?
Generally No. The capture file is a binary file that must be uploaded to the testmyworkload.com site.
However, you can view captures in private if you purchase an IO Profiler Tool or Calypso Test System.
An IPF Tool allows you to run the features of testmyworkload.com on your local server.
A Calypso Test System allows you to automatically create test scripts from captures and run these as tests on SSDs.
13. Can I test SSDs using my captured workload definitions?
Yes, but you must purchase a Calypso Test System or our Test Services.
You can also purchase an IO Profiler Tool and then add the Calypso Drive Testing module later .
The Calypso Drive Test module allows you to test SSDs.
For more details, contact Calypso.
14. How do I buy a Calypso IO Profiler Tool and/or a Calypso Test System?
