Using HCIBench to benchmark vSAN – Part 3: Test

Using HCIBench to benchmark vSAN – Part 3: Test

You’ve deployed HCIBench, you’ve configured HCIBench, now it’s time to see what your vSAN cluster can do!

Still with me?  Okay good!!  So to recap we deployed the HCIBench Controller VM in Part One of this series, then we configured it in Part Two.  Let’s crack on with the third and final part where we’ll kick off the test then hit paydirt with some lovely performance benchmarks!

Without further ado let’s get to it!  Go ahead and hit ‘Test’ to kick us off

You’re away! Depending on your parameters and environment the deployment time can vary- I ran this example on a six-node hybrid cluster using Easy Run and it took around 3 hours- however a quick check on your vCenter will show that it’s all kicking off in the background…

So you can follow the progress by clocking the Recent Tasks in your vCenter, if that’s your bag, otherwise I’ll see you when it’s all in the books!

But wait- what if something goes wrong? Well if you get any errors or failures during the testing, you can point your web browser to http://<Your_HCIBench_IP>/hcibench_logs/ to investigate.

Still going….

Still going, and a sneaky look at the vSAN performance graphs shows things are indeed heating up…

Now it’s getting serious…

…aaaand we’re done!

So now let’s take a look at the results. Hit ‘Results’ at the bottom of the HCIBench configuration screen and you’ll get your results listed

All the individual Vdbench tests are logged here, along with the parameter file used to generate the results, and vSAN Observer data as well. Let’s take a look at what you get. Drill into the folder and you’ll get another folder and text file- this text file basically aggregates all the results into a few lines so you can see what you’re dealing with. Go ahead and open it up and see how your cluster performed!

I’m sure you’ll be suitably impressed. Drill further into the folder and you can view the individual test results. Two folder levels down and you’ll see the Observer stats- open up the ‘stats.html’ file for some nice graphical representations of your cluster being put through it’s paces.

So there you have it!! For the latest releases of HCIBench check the Fling page at

Good luck with your HCI benchmarking, show us some love and let us know what sort of results you’re seeing from your configurations.
