Thunderbolt to 10GbE Network Adapters for ESXi

03.15.2018 by William Lam // 5 Comments

I was recently made aware of this article in which the author, Karim Elatov, had successfully demonstrated the use of a Sonnett Thunderbolt 2 to 10 Gigabit Ethernet Adapter with ESXi running on an Apple Mac Mini. As far as I am aware of, this may be the first public confirmation that such a device would work with ESXi, not to mention having it functional on the Mac Mini. I know in past years, there have been unconfirmed reports on various forums mentioning a Thunderbolt to 10GbE solution that works with ESXi but it was unclear on whether custom drivers were needed or if it would even work with newer versions of ESXi.

This topic has been popular amongst our customers who virtualize Apple MacOS on vSphere. In fact, several years back I had written an article on Thunderbolt Storage for ESXi, which includes a number of solutions that our customers have implemented to provide remote storage for their vSphere infrastructure running on either an Apple XServe, Mac Pro or Mac Mini. Questions around a functional Thunderbolt to 10GbE has definitely been asked about, but I had never heard from any customer who have had a successful story to share, at least until now.

From Karim's post, it looks like he was able to get this working using ESXi 6.0 but it was unclear if there was anything he needed to do to get the device recognized. I reached out to Karim and he was able to confirm that the Thunderbolt device was recognized by ESXi without any additional driver installation. In fact, if you look at this console output on his blog, you will see that it simply uses the inbox Intel ixgbe driver. I had also asked if Karim tried this with the latest version of ESXi, which is currently at 6.5 Update 1. Karim was kind enough to perform one additional test for me which was to confirm the device would still work with the latest ESXi release, which you can see for yourself in the screenshot below.

ATTO's ESXi Thunderbolt Driver is now officially on VMware HCL

08.22.2017 by William Lam // 1 Comment

Last week I had received some great news from our friends over at ATTO Technology that their ESXi Thunderbolt to Fibre Channel Driver has passed the VMware Certification process and is now officially listed on VMware's HCL. I had known the team was planning to certify their driver but was not aware of their timelines and whether it would actually get accepted given the fact that this was for a Thunderbolt-based device, which is the first of its kind for the VMware HCL.

Funny enough, it was roughly around this time last year that ATTO released a Beta of their ESXi Thunderbolt to Fibre Channel Driver which I had shared with my readers here. I was not surprised by the demand given the fact that no official solutions exists for customers who would like to take advantage of their existing SAN-based storage infrastructure when virtualizing Apple macOS (iOS development, etc) on vSphere. ATTO has certified two of their ThunderLink devices, customers have the option of using either the TLFC2082 which provides 20Gb/s Thunderbolt 2 (2-port) to 8Gb/s FC (2-Port) Device or the TLFC2182 which provides 20Gb/s Thunderbolt 2 (2-port) to 16Gb/s FC (2-Port) Device which is supported from ESXi 5.5u3 all the way up to latest 6.5u1 release.

Huge congrats to the ATTO team for getting this on the VMware HCL and partnering up with VMware to provide a solution for our customers who virtualize Apple macOS using vSphere!

Lastly, if you are going to be at VMworld and you are interested in learning more about this solution, be sure to drop by the ATTO booth.

ESXi Thunderbolt Driver to Fibre Channel Storage from ATTO

One of the things I always enjoy doing at VMworld, when I am not running around and I have a few minutes to myself, is to check out the VMware Solutions Exchange. This is where you can learn and interact with hundreds of our VMware Certified Partners showcasing their new solutions and innovations that they have built on top of VMware's products.

UPDATE (08/22/17) - ATTO's ESXi Thunderbolt Driver is now officially on the VMware HCL, please see this blog post here for more details.

While walking through the show floor, I had stopped by the ATTO Technology booth who has been a long time partner of VMware in the storage and networking connectivity space. What caught my eye was that they had just released a Beta of an ESXi Thunderbolt Driver in the form of an ESXi VIB that would allow customers to connect their Apple Mac Pro 6,1 using the Thunderbolt 2 interface to an external Fibre Channel storage array. I believe ATTO might be the first vendor ever to produce a Thunderbolt Driver for ESXi. This is really exciting news if you ask me, especially as more and more of our customers are looking to virtualize Mac OS X guests in their Datacenters using vSphere.

Historically, the only option to connect a Mac Pro 6,1 to an external Fibre Channel array was to use something like a Sonnet Chassis. Now, you can potentially connect up to 6 of the built-in Thunderbolt 2 interfaces on the Mac Pro's to your external storage array using this new solution from ATTO. Before I go into some of the details, ATTO did want me to mention that this solution is currently not officially supported by VMware nor is it on VMware's HCL. ATTO will be providing full support on their software as well as VMware's software stack during the duration of the beta program. In terms of official certification on VMware's HCL, I suspect that it will most likely depend on customer demand which would influence whether ATTO applies for an official certification, which again, would be the first of its kind for Thunderbolt.

The way in which this solution works is that you install the ATTO Thunderbolt Driver on your ESXi host and this will allow it to communicate with an ATTO ThunderLink device which provides the Thunderbolt 2 to Fibre Channel connectivity. You have the option of using either the FC2082 which provides 20Gb/s Thunderbolt 2 (2-port) to 8Gb/s FC (2-Port) Device or the FC2182 which provides 20Gb/s Thunderbolt 2 (2-port) to 16Gb/s FC (2-Port) Device. Below is a diagram from the ATTO digital solution brief on Thunderbolt Driver for ESXi which outlines the configuration.

If you are interested in taking part in ATTO's ESXi Thunderbolt Driver Beta program or would like to learn more about the solution, you can reach out directly to Carllene Mowry (*protected email*) who is running the program. For more information be sure to check out the ATTO digital brief on Thunderbolt Driver for ESXi.

Lastly, I was also fortunate to have a quick chat with Carllene and team to get a few additional exclusive tidbits on some of the things the ATTO team is working on next. The first of which is support for the Thunderbolt 3 (aka USB-C) interface to Fibre Channel which will be quite nice for newer platforms that include that interface, including home lab setups such as the Intel NUC. Speaking of Intel NUC, this is just one of the many other platforms that include either Thunderbolt 2 or 3 interfaces. Although the solution today is specifically supporting the Mac Pro, I know ATTO folks are interested to hear from customers on other systems with Thunderbolt interface and providing similiar capabilities.

The other really exciting development that is currently being investigated is support for Thunderbolt 2 or 3 to 10GbE connectivity on ESXi. As you can imagine, this is really going to open up some really cool new use cases, especially around things like VSAN which can easily benefit from this. It is still in early development but from my understanding, ATTO is already seeing a lot of interest in this area as well as how this might work with VSAN. I am hoping I will be able to share more details as this further develops. If any of these updates sounds interesting, do leave a comment to let the ATTO folks know and I will make sure they monitor the thread.
