Sonnet Solo5G Multi-Gig (1G/2.5G/5G) USB Adapter works with ESXi

by // 5 Comments

Last week I caught this tweet from Blake Garner who is an active VMware Community member that I follow and I came to learn that Sonnet just launched their first Multi-Gigabit (1GbE, 2.5GbE & 5GbE) USB Network Adapter called the Solo5G.

This of course piqued my interest for VMware Homelabs as last year we had just enabled the first Multi-Gigabit USB Network Adapter from QNAP supporting ESXi using the popular USB Native Driver Fling for ESXi. The QNAP device uses an Aquantia chipset and I had a funny suspicion that the Sonnet device might be using either the exact same or simliar chipset.

To confirm my theory, I reached out to the folks over at Sonnet and they were kind enough to send me a unit for validation which just arrived earlier this week. I had an Intel NUC 10 (Frost Canyon) already running and I just plugged it in and to my surprise it worked immediately since it already had the USB Native Driver Fling installed.


So there you have it, same chipset as the QNAP and best of all this device is only $79.99 USD which be purchased directly from Sonnet here. As of writing this blog post, the Solo5G is much cheaper than the QNAP. In fact, it seems the price of the QNAP has significantly increased since I had first blogged about it. I think multi-gig NICs both USB-based but also PCIe and respective switches is starting to become more mainstream, at least in the consumer markets and this is certainly an easy way to add additional bandwidth without breaking the bank. Big thanks to the folks at Sonnet and Blake for sharing the news!

ESXi on Intel NUC 10 (Frost Canyon)

by // 64 Comments

Just a heads up, if you are considering the latest 10th Generation of the Intel NUC (formally known as Frost Canyon) which are now available on Amazon, Newegg & SimplyNUC, there is an issue to be aware of. The onboard Intel NIC is not detected by ESXi which prevents the installer from proceeding. This issue was reported by a fellow reader named Ben who reached out to me over the holiday and with his help, I was able to get access to the system. It looks like the these NUCs have a newer version of I219-V NIC which is currently not recognized by either the vmklinux e1000 or ne1000 driver.

UPDATE (09/21/20) - The required ne1000 driver has been incorporated into ESXi 7.0 Update 1

UPDATE (08/21/20) - To disable the TPM 2.0 connection cannot be established message in ESXi, please see this blog post for more details.

UPDATE (01/20/20) - As shared on Twitter last Friday, we now have an updated ne1000 driver that will detect the Intel NIC found in the new 10th Gen NUC. You will need to replace the existing ne1000 driver with the new offline bundle, which can be downloaded from here. I would like to remind folks that the Intel NUC is not an officially supported platform from VMware and although have have enable this new system for the community, it does not mean this system or previous generations are supported.

There are two options to author a new ESXi Image Profile containing the ne1000 driver, the easiest method is if you have an existing vCenter Server and using the vSphere H5 Client and Image Builder UI. For more details, please take a look at this blog post for detailed instructions.

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.
