New Thunderbolt 3 to 10GbE options for ESXi

by // 78 Comments

With the help from Aquantia, we now have an ESXi driver to enable the built-in 10GbE adaptor for both the Apple 2018 Mac Mini and the iMac Pro. Although this was exciting news for our VMware/Apple customers, I was actually more excited for what this development meant for the larger VMware Community when it comes to 10GbE accessibility.

Many Enterprise customers have already been using Thunderbolt 2/3 to access their 10 Gigabit infrastructure, usually over SFP+ but Ethernet based options also exists such as the Sonnet solution which I had shared last year. This is especially common for VMware customers who virtualize Apple MacOS on vSphere for MacOS/iOS development and the use of Thunderbolt enables ESXi to connect to the underlying storage and networking infrastructure, which traditionally has been either Fibre Channel and/or IP-based storage running over a 10Gig link.

When you start looking at 10GbE accessibility for VMware home labs which could potentially apply to remote office/branch office (ROBO) and Edge/IoT environments, the cost and the complexity of the setup is something that many folks have to consider. There are definitely some creative options out there, most recently Chad Moon shared his solution using a Thunderbolt 3 to PCIe expansion chassis with his Intel NUCs which will run you about $230 per setup or you can be a true hardware hacker like Jack Harvest and use one of the M.2 slots in the Intel Skull Canyon NUC and connect that to PCIe 10GbE SFP+ card with a custom 3D printed chassis to hide everything for just $43.68 🙂

ESXi Native Driver for USB NIC Fling

by // 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.

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

by // 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.
