Running Nested ESXi, NSX-V or NSX-T on top of NSX-T

by // 6 Comments

Nested Virtualization is an extremely useful tool that helps customers easily test and try out new VMware products and solutions before rolling that into a proper development environment for further validation. This is especially handy for those wanting to setup an NSX-based environment and simulating their actual deployment topology, configuration and upgrade workflows.

In this past year, I have seen a 10x increase in the number of NSX-T based questions that have come up from customers and our field, the adoption of NSX-T is definitely in full swing. As expected, questions about running Nested ESXi on top of a physical NSX-T deployment has come up and there has actually been several variations that have been asked about whether that is Nested ESXi using VSS, VDS, NSX-V or even NSX-T running on top of an N-VDS, which is the virtual switch that NSX-T uses.

Luckily all of these combinations work and just require some basic configuration changes within NSX-T. However, before I continue, let me remind folks again that VMware does NOT officially support Nested Virtualization.

Hands on with new AMD "NUC" platform from ASRock 

by // 7 Comments

It has been rumored for some time now that AMD would be re-entering the embedded/small form factor (SFF) market and with their latest generation of Ryzen CPUs, timing could not be more perfect. With the rise of Edge and IoT workloads, new constraints like cost, footprint, low to no tech-touch and power consumption is now top of mind more than ever for customers.

At VMware, we certainly see interests from customers across this spectrum whether it is a traditional "ROBO" environment running a handful of Virtual Machines for a supermarket or retail chain to an industrial site such as an oil rig or factory to mobile infrastructure like a car, ship or even a submarine. On top of these use cases, personal and development labs continue to be extremely popular amongst our customer base for learning and training purposes.

Today, the Intel NUC is still by far the most popular platform due to its size, portability, cost and low power consumption for running VMware vSphere, vSAN & NSX. The idea of an AMD "NUC" kit which includes a chassis, motherboard and CPU is something that that many folks have been asking for. With the market mostly dominated by Intel, I certainly welcome AMD re-entering this market as this will certainly drive new solutions and innovations in this market. With that said, AMD has re-entered into this market and this is initially through partnerships with several OEMs/manufacturers.

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

by // 10 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.

UPDATE (06/08/20) - QNAP has just published the updated firmware for their QNA-UC5G1T USB NIC which resolves some of the performance issue observed with the initial release.

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.
