ESXi on GMKtec NucBox K11

by // 7 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!

ESXi on GMKtec EVO-X1 with AMD Ryzen AI Pro 300 Series (formally Strix Point)

by // 4 Comments

My experiences with small form factor (SFF) systems and Mini PCs over the years have primarily involved Intel-based systems, as they have been the most capable and compatible with the VMware ESXi Hypervisor—especially when it comes to onboard networking options.

Intel's introduction of their Hybrid CPU core architecture starting with 12th Gen (Alder Lake) and continues with 13th Gen (Raptor Lake), 14th Gen (Meteor Lake), and now 15th Gen (Arrow Lake), presents a unique challenge for running ESXi.

When AMD announced their Ryzen AI 300 Series processors (formally codenamed Strix Point) based on their new Zen 5 architecture, I was pretty excited with their approach to a "Hybrid" processor:

AMD's approach to its 'compact' Zen 5c cores is inherently different than Intel's approach with its e-cores. Like Intel's E-cores, AMD's Zen 5c cores are designed to consume less space on a processor die...But the similarities end there. Unlike Intel, AMD employs the same microarchitecture and supports the same features with its smaller cores.

Since both the Zen 5 and Zen 5c cores contain the exact same CPU features, they would be considered uniform cores unlike the Intel platform, which now includes three different core types (Performance, Efficiency & Low-Power Efficiency), requiring additional workarounds to be able to utilize most of the cores available on the SoC.

While there is currently only a handful of Ryzen AI Pro 300 Series kits that are available for purchase, I was fortunate to get hands on with one from a company called GMKtec, who is a relatively new player in the small form factor market. I have personally never used a GMKtec system before, so I was looking forward to seeing what they had to offer.


Disclaimer: As of publishing this blog post, a fellow colleague has not had any luck in contacting GMKtec to initiate a return, they have been completely non-responsive for several weeks now. I have also observed simliar negative feedback on various Reddit threads, which is certainly concerning for potential prospects. Users may want to consider purchasing GMKtec systems using Amazon, rather than directly from the vendor in case you need an exchange or return.
