HCIBench stands for Hyper-converged Infrastructure Benchmark. It is an automation wrapper around open source benchmark tools that automates proof-of-concept performance testing across a cluster. The tool fully automates the end-to-end process of deploying test virtual machines, coordinating workload runs, aggregating test results, performance analysis, and collecting necessary data for troubleshooting purposes.
The HCIBench 2.6.0 OVA file can be downloaded from VMware Fling. You can find more information about it on the VMware Fling site.
For the purpose of this installation, you download and configure HCIBench 2.6.0 in order to verify network connectivity and test vSAN performance. You will be able to estimate whether your platform is performing within the expected range of parameters. Running this tool can also help you identify configuration issues.
In vCenter select your cluster and right click to choose Deploy OVF Template.
Under Select an OVF Template, select URL, enter the following and click Next. If you have already downloaded the OVA, select Local file instead and point to your downloaded OVA file.
Accept the source verification.
Select the datacenter, choose a name for the virtual machine, and click Next.
Select the cluster and click Next. The template will start downloading.
Review the details and click Next.
Read and accept the license agreements and click Next.
Select the vSAN datastore and click Next.
gp-virtual-external port group for Management Network, and
gp-virtual-internal for VM Network.
Under Customize Template, settings are displayed for DHCP by default. If you are not using DHCP, enter the static IP network information for the
root password for the virtual machine and click Next.
Verify the configuration and click Finish.
The HCIBench virtual machine will be deployed. You can check its progress under the Recent Tasks tab on the vSphere client.
Once deployment is complete, power on the virtual machine. When the IP address has appeared in vCenter, open the HCIBench UI in your browser by accessing https://IPADDRESS:8443.
root username and password you configured earlier and start configuring HCIBench.
Scroll down the page and configure the following:
Under Testing Configuration, you create and run three different tests: Write, Long Write and Read. Note that these must be created and run one at a time, and then deleted before creating a new one.
Enter a Test Name that is meaningful.
Under Select a Workload Parameter File, click Add and use the corresponding values for each test type:
|Number of Disks to Test||8||8||8|
|Number of Threads Per Disk||4||4||4|
|Worker CPU Usage Percentage||OPTIONAL||OPTIONAL||OPTIONAL|
Click Submit and OK.
Click the Refresh button next to Select a Workload Parameter File and select the one you just created from the dropdown menu.
For Prepare Virtual Disk Before Testing set to ZERO for the first run to initialize storage. Consecutive runs can be set to NONE as it will shorten the test duration.
Leave Testing Duration (Seconds) as OPTIONAL.
Disable Delete VM After Testing.
Click Save Config.
Click Validate Config.
Click Start Test.
Once the test is complete you can review the results.
In order to run a different test, you should first remove the current parameter file:
Once the test completes, click on Review Result, access the directory with the test name and open the provided PDF report file to display a breakdown of the different parameters that the test has measured.
You are now ready to start setting up and deploying a Greenplum Database cluster on your Dell EMC VxRail with vSphere environment. Make sure that you have enabled vSphere DRS again and proceed to Creating the Jumpbox Virtual Machine to install a jumpbox virtual machine which you will use to run Terraform to provision the Greenplum Database virtual machines.
