ESXi on GMKtec NucBox K11

by // 3 Comments

The GMKtec NucBox has been growing in popularity amongst the VMware community as a modern AMD Ryzen-based alternative to the Intel/ASUS NUC, offering many of the same advantages while avoiding some of the drawbacks of Intel's Hybrid CPU architecture.

In preparation for my upcoming session at the inaugural VMUG Connect Conference in April, I have been experimenting with several modern hardware options, with the goal of deploying the full VMware Cloud Foundation (VCF) solution for use within a lab environment, while still staying budget friendly!

I know several folks have had great success with the GMKtec NucBox K8 Plus and it just so happens, while browsing the GMKtec website, I noticed an additional NucBox has just been released called the K11.


While the differences between the K8 Plus and K11 is pretty minimal, I was interested in validating some new hardware add-ons, so getting the latest hardware would hopefully give me the best chance!

In collaboration with the VMware {Code} team, I was able to get hands on with the latest GMKtec NucBox K11!

Quick Tip - VMware Cloud Foundation (VCF) Bringup fails without persistent ESX-OSData

by // 5 Comments

You will never run into this problem if you follow current recommended practices to install the ESX-OSData volume on a persistent storage device that could either be dedicated and/or co-located your ESXi installation.

For those deploying VMware Cloud Foundation (VCF) in a lab environment, you might attempt to reserve the limited number of storage devices for use with vSAN and decide to install ESXi on a USB device, which is perfectly fine but if you do not select a persistent storage device for the ESX-OSData volume, then it will default to use the ESXi ramdisk.

I recently observed that if you have such a configuration, the VCF Cloud Builder Bringup process will fail after attempting (three times) to re-deploy the vCenter Server Appliance (VCSA).


As you can see from the screenshot above,  VCF Cloud Builder UI does not provide any details and ask users to look at the vCenter Server installation logs.

Enhancements to VMware Cloud Foundation (VCF) & vSphere Automated Lab Deployment Scripts

by // 2 Comments

Simplicity is something I try to strive for when creating automation, whether that is for myself or for our customers. When I develop a script, I try to keep everything within a single file, so that it is easy to share and consume. As a script increases in functionality, it may be useful to break out some of its functions, typically libraries or modules.

I was recently debugging an issue with my popular automated lab deployment script for VMware Cloud Foundation (VCF) and while looking through the script that the user had been using, I found numerous variables that were commented out and replaced with their own values, which looked like they had different configuration and environments where they were using this single script.

It then hit me, why have I not considered externalizing all the variables that the script relied on, such that a user could easily supply different configuration options without needing to edit the primary deployment script!? 😅
