Thunderbolt 3 enclosures with (Single, Dual & Quad) M.2 NVMe SSDs for ESXi

by // 15 Comments

Thunderbolt 3 (TB3) and eventually USB 4 is a really fascinating technology and I believe it still has so much untapped potential, especially when looking at Remote/Branch Office (ROBO), Edge and IoT types of deployments. TB3 was initially limited to Apple-based platforms, but in the last couple of years, adoption has been picking up across a number of PC desktop/laptops including the latest generations of Intel NUCs which are quite popular for vSphere/vSAN/NSX Home Labs. My hope with USB 4 is that in the near future, we will start to see servers with this interface show up in the datacenter 🙂

In the mean time, I have been doing some work with TB3 from a home lab standpoint. Some of you may have noticed my recent work on enabling Thunderbolt 3 to 10GbE for ESXi and it should be no surprise that the next logical step was TB3 storage. Using a Thunderbolt interface to connect to external storage, usually Fibre Channel is something many of our customers have been doing for quite some time. In fact, I have a blog post from a few years back which goes over some of the solutions customers have implemented, the majority use case being Virtualizing MacOS on ESXi for iOS/MacOS development. These solutions were usually not cheap and involved a sizable amount of infrastructure (e.g. storage arrays, network switches, etc) but worked very well for large vSphere/MacOS based environments.

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.
