ESXi Native Driver for USB NIC Fling

02.12.2019 by William Lam // 35 Comments

Today, I am very excited to announce a new Fling that I have been working on which is a Native Driver for ESXi that will enable support for three of the most popular USB network adapter chipsets found in the market today. The ASIX USB 2.0 gigabit network ASIX88178a, ASIX USB 3.0 gigabit network ASIX88179 & the Realtek USB 3.0 gigabit network RTL8153. This effort had initially started back in 2016 as a side project with Songtao, a VMware Engineer who works on our USB stack for ESXi. Based on the enormous amount of feedback from the community as well customer Production use cases, this side project evolved into the development of a full fledge Native Driver for ESXi.

This Fling is more than just adding additional network interfaces for vSphere Home Labs, which is definitely a use case, but it is also about enabling new and future computing platforms that may not always have the traditional network connectivity that we have come to expect. Today, ESXi supports a number of high-end network controllers (10G/40G/100G) designed for Enterprise Data Centers that include advanced networking & low latency features. As more & more workloads appear at the Edge like IoT, point-of-sales & remote office use cases, the traditional networking solutions may no longer meet the needs of these new infrastructures.

For Edge computing environments, reducing the cost & power consumption is definitely one of the driving factors. However, with some of these platforms, their form factors can make it difficult or impossible to support traditional high-end network controllers. Luckily, there are a number of options for network adapters in the market but is can also be difficult to support them all.

USB has become one the most widely adopted connection type in the world & USB network adapters are also popular amongst Edge computing platforms. In some platforms, there is either limited or no PCI/PCIe slots for I/O expansion & in some cases, an Ethernet port is not even available. This Fling will hopefully help enable some of these Edge use cases today and with the help of the community and feedback, we can see how this can be enhanced or evolved over time including where it could even be part of the ESXi distribution.

Another use case for USB-based network adapters as mentioned earlier are for vSphere Home Labs, platforms like the Intel NUC or Apple Mac Mini have limited number of built-in Ethernet ports, but plenty of USB & USB-C ports which can enable these platforms with additional networking capabilities. These systems could also be potential Edge platform candidates given the right connectivity.

GPU Passthrough of Radeon RX Vega M in Intel Hades Canyon

01.15.2019 by William Lam // 71 Comments

With the latest Intel Hades Canyon now being able to run ESXi, a number of folks have been interested in taking advantage of the integrated GPU that is included in the system. There are two models of the Hades Canyon, NUC8i7HNK which is the lower end system with Radeon RX Vega M and the NUC8i7HVK which is the higher end system with Radeon RX Vega GH. One of the first thing I had attempted after getting ESXi working on the Hades Canyon was to try to enable passthrough of the iGPU into a Windows GuestOS but in all my attempts, it resulted into a PSOD'ing the ESXi host once you start installing the AMD Drivers from Intel.

A few days ago, one of my readers, Chris78 shared an update where he was able to prevent the ESXi host from PSOD'ing by adding a VM Advanced Setting but he he was still having issues where the Windows GuestOS would now BSOD. This sounded promising, I figure it would not hurt to gave it a try and to my surprise, I was able to successfully passthrough the iGPU to a Windows 10, Windows Server 2016 and 2019 system from my limited testing. After reporting the success back to Chris78 who was still having issues even after using the settings I had used, his conclusion was there may be a difference between the HNK and HVK models, with the latter having BSOD issues. For now, it seems like iGPU can only be passthrough if you have the NUC8i7HNK model.

Supermicro E300-9D (SYS-E300-9D-8CN8TP) is a nice ESXi & vSAN kit

11.23.2018 by William Lam // 33 Comments

Supermicro kits such as the E200-8D is a very popular platform amongst the VMware community and with powerful Xeon-based CPUs and support for up to 128GB of memory, it is perfect for running a killer vSphere/vSAN setup!

Earlier this Fall, Supermicro released a "big daddy" version to the E200-8D, dubbed E300-9D and specifically, I want to focus on the 8-Core model (SYS-E300-9D-8CNTP) as this system actually listed on the VMware HCL for ESXi! The E300-9D can support up to half a terabyte of memory and with the 8-Core model, you have access to 16 threads. The E200-8D is also a supported platform by VMware, you can find the VMware HCL listing here.

I was very fortunate to get my hands on a loaner E300-9D (8-Core) unit, thanks to Eric and his team at MITXPC, a local bay area shop specializing in embedded solutions. In fact, they even provided a nice vGhetto promo discount code for my readers awhile back, so definitely check it out if you are in the market for a new lab. As an aside, when doing a quick search online, they also seem to be the only ones actually selling the E300-9D (8-Core) system which you can find here and in general, they seem to be priced fairly competitively. This is not an endorsement for MITXPC, but recommend folks to compare all prices when shopping online, especially as today is Black Friday in the US and Cyber Monday is just a few days away.
