USB Native Driver Fling for ESXi adds support for Multi-Gig (1G/2.5G/5G) Adapter

09/27/2019 by William Lam 3 Comments

Today, we have an exciting update to give on our USB Network Native Driver for ESXi Fling which has had two updates since releasing earlier this year and has been extremely well received by the VMware community. As many of you know, I am always on the look out for new and innovative tech that can help enable our customers, especially when it comes to building home labs to learn about the latest and greatest VMware software.

Several months back, I came to learn about a really cool USB-based Multi-Gigabit Network Adapter (QNA-UC5G1T) from QNAP which can negotiate with speeds up to 1Gbps, 2.5Gbps and 5Gbps. I was not familiar with the multi-gig specification but it it looks like it was created as a standard back in 2016 as IEEE 802.3bz. This initially evolved from advancements in wireless technology but more recently it started to make its way into ethernet-based devices.

Although this particular device is from QNAP, the underlying chipset is actually from Aquantia, now part of Marvell. If the name sounds familiar, it should as Aquantia is also the vendor to Apple for their 10GbE NICs in both the 2018 Mac Mini and new iMac Pros. In fact, their chipsets are also used in a number of Thunderbolt 3 to 10GbE NICs which also works with ESXi. Access to 10GbE is certainly more common these days but it certainly is not for everyone and not all platforms can be expanded to support it.


The QNA-UC5G1T device is not only small but because it is USB-based, you are more likely to have spare USB ports on your system than say a traditional PCIe slot or Thunderbolt 3 port. From a cost standpoint, this device is about half the cost of the 10GbE Thunderbolt adapter coming in at $79 USD and can be ordered from Amazon. As far as I know, QNAP is the only vendor who has produced a multi-gig USB adapter, but perhaps in the future, there will be other vendors.

New hardware support & enhancements to USB Network Native Driver for ESXi

06/17/2019 by William Lam 1 Comment

Since releasing the USB Network Native Driver for ESXi Fling back in February, the feedback and support for this Fling has simply been amazing. I especially enjoy hearing from customers, almost on a weekly basis, on how they are taking advantage of this solution in their vSphere/vSAN/NSX home lab and enabling for more complex networking topologies.

When we released the fling, we had focused on the most popular USB 3.0 network adaptors that we had accessed to which were based on AX8817a, AX88179 & RTL8153 chipsets. The initial list started out with just 5 devices, but we knew there were going to be others. In fact, Songtao and I have received plenty of feedback from our customers on what they would like to see supported, including USB 2.0 network adaptors. Another highly requested feature that customers have been asking for is support for Jumbo Frames and this is usually in the context of setting up either an NSX-V or NSX-T environment.

ESXi Native Driver for USB NIC Fling

02/12/2019 by William Lam 30 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.

Automatically retrieve CVE CVSS score for all ESXi security bulletins 

07/20/2018 by William Lam 9 Comments

I always enjoying learning new things, especially when it is outside of my immediate domain expertise and if I can thrown in some Automation to help solve a solution, it is a win for everyone. I bring this up because, yesterday I had noticed an interesting question from one of our field folks where their customer is looking to implement a process for applying ESXi security patches to help determine compliance timeline (e.g. when a specific security update will be applied to infrastructure).

To do this, the customer would like to use the Common Vulnerability Scoring System (CVSS) score which ranges from 0-10, 0 being low and 10 being high. The CVSS score is part of the Common Vulnerabilities and Exposures (CVE) which is also referenced for every ESXi security patch (bulletin) that is published by VMware. The question that came up was how easily it would be to determine the CVSS score for a given ESXi security patch. First, I will outline the "manual" process and once that is understood, I will demonstrate an automated solution which customers can take advantage of to easily retrieve this information for all ESXi security patches.

vGhetto Automated NSX-T 2.0 Lab Deployment

10/24/2017 by William Lam 21 Comments

Last week, I had spent some time exploring and getting myself more familiar with NSX-T, which is the next generation release of the NSX platform from VMware. One of the first thing I do when learning about a new product is to setup a lab environment that I can using. Having gone through the deployment once by hand, I realized it would be quite painful if I needed to do this again, which I know I will and I did 🙂 I wanted to have a simliar experience to my vGhetto Automated vSphere Lab deployment script which also including setting up the entire vSphere infrastructure along with deploying and configuring NSX-V and extending it to support NSX-T.

Since my original script leverages PowerCLI to access both the vSphere and NSX APIs, I wanted to do the same with NSX-T. Funny enough, the PowerCLI team had just published an update release (6.5.3) which also added support for NSX-T and I thought this was perfect timing to try out the NSX-T APIs, which I had never used before.

UPDATE (01/01/2018) - I have verified the script also works with the latest NSX-T 2.1 which was just released before Christmas. The script has also been updated to create a new Edge Uplink Profile along with an Edge Cluster and automatically associate all Edge VMs to Edge Cluster.

I have created a new Github repository called vghetto-nsxt-automated-lab-deployment which contains detailed instructions along with the PowerCLI script.

Here is what the script is currently performing:

  1. Deploy and configure vCenter Server Appliance 6.5u1
  2. Deploy and configure 3 x Nested ESXi 6.5u1 Virtual Appliance VMs and attaching it to vCenter Server
  3. Deploy NSX-T Manager, 3 x Controllers & 1 x Edge and setup both the Management and Control Cluster Plane
  4. Configure NSX-T with IP Pool, Transport Zone, Add vCenter Server as Compute Manager, Create Logical Switch, Prepare ESXi hosts, Create Uplink Profile & Add configure ESXi hosts as a Transport Node

Similiar to the vSphere version of this script, all deployed VMs will be placed inside of a vCenter vApp construct as shown in the example screenshot below:


Here is an example output of a succesful deployment and you go from nothing to a fully functional NSX-T environment in just 50 minutes, which is pretty awesome if you ask me!?

Project USB to SDDC – Part 3

05/11/2017 by William Lam 30 Comments

OK, the wait is finally over! In this final article, we will now walk through the process of getting access to this project as well as how to get this deployed in your own environment. For those that just want to see the code, you can find it at the Github project below:

Github Project: https://github.com/lamw/usb-to-sddc

Below are the details outlining the environment and software requirements as well as the instructions to consume this in your own home lab environment. The content below is a subset of what is published on the Github project, but this should get you going. For more details, please refer to the Github project and if you have any issues/questions, feel free to file a Github issue.

Environment Requirements:

  • USB key that is at least 6GB in capacity
  • Access to either macOS or Linux system as the script that creates the USB key is only supported on these two platforms
  • No additional USB keys must be plugged into the hardware system other than the primary installer USB key
  • Hardware system must have at least 2 disk drives which can either be 1xHDD and 1xSSD for running Hybrid vSAN OR 2xSSD for running All-Flash vSAN
  • Both Intel NUC 6th Gen and Supermicro E200-8D and E300-8D have been tested with this solution. It should work with other hardware systems that meet the minimum requirements but YMMV

Software Requirements:

  • ESXi 6.5a - VMware-VMvisor-Installer-201701001-4887370.x86_64.iso
  • VCSA 6.5b - VMware-VCSA-all-6.5.0-5178943.iso
  • DeployVM.zip
  • UNetbootin (Required for Mac OS X users)

Note: Other ESXi / VCSA 6.5.x versions can also be substituted, this includes the latest ESXi 6.5d (vSAN 6.6) release which I have also verified myself.

UPDATE (04/17/18) - No changes are required to get vSphere 6.7 to work, the only minor thing to be aware of is that the vSphere Web Client customization has changed in 6.7 and so you need to set VCSA_WEBCLIENT_THEME_NAME="" as empty string or you will find that the UI will not load unless you delete the customization directory in the VCSA that was pulled down automatically.
