Hi all, I am currently trying to set up 10 Gigabit Ethernet on laptop through a Thunderbolt™ 3 port. Thunderbolt™ 3 supports up to 40Gbps, so that I suppose it can be adapted to a 10 Gigabit Ethernet port (or PCI). But I am not sure how to do it, and I didn't find any material on this yet. Please let me know if you have any suggestions. Thanks for any help, Zhihong

Dear Zhihong, I have successfully set up a MacBook + X300 connected via 10 GbE. I used this product: http://www.sonnettech.com/product/echoexpresssel_10gbeadapter.html to adapt Thunderbolt to 10 GbE. It worked out-of-the-box. The only (major!) issue I have now is that the host cannot keep my desired sampling rate (92.16 Msamples/s) without buffer underruns. Since the CPU is far from being overloaded, I suspect it might have something to do with interrupts and how the OS handles them. If anyone has experience or guidelines on how to optimize host-to-radio communication on Mac OS X I would appreciate it very much if you could share.

Hi Claudio, Thank you so much for the sharing. Problem is that there seems to be no available adapter for Thunderbolt3 to Thunderbolt 2/1 yet... What's the highest sample rate you can run without having any underrun issues? I am looking for roughly 60 MS/s, if it can work on this rate, I can try to use a laptop with old Thunderbolt port.

Dear Zhihong I am able to receive at 100 MS/s (i.e., ~3.3 Gb/s over the wire). At that rate I only experience under-runs when the OS runs background jobs (such as re-building indexes of the spotlight or iTunes database) that choke all CPUs and my application as well. I am trying to disable all such background jobs, which is proving more painful than it should reasonably be because of my lack of experience with Mac OS X...

Out of personal curiosity: does that thunderbolt/10GE adapter work under linux, e.g. with the GNU Radio Live DVD?

Dear Marcus, If it worked, that would make my life soooo much easier. Frankly, I didn't even try since I had to install a (Mac OS X only) driver on the MacBook to make the adapter work. Yet, I will give it a try and will keep the list posted on this.

You sparked my own initiative: Went to the sonnettech website, clicked through to the presto 10GE card that's inside the box, got the windows driver, looked at the URL: It's a Myricom Myri10GE ! If it works over thunderbird, too, then there should be drivers in the upstream linux kernel since 2.6.something :) ; module name is "myri10ge", iirc.

Dear Marcus, Will try asap (downloading DVD live right now). If it works I owe you a pint.

Hi all, We have been using the Promise Technologies SanLink2 successfully under MacOS, Windows and Linux Ubuntu (Macbook and Asus ROG laptops). Its a Thunderbol2 to 10GbE converter. http://www.promise.com/Products/SANLink/SANLink2 However, newer laptops come with Thunderbolt3 (via a USB Type C connector), and we have not found any solution yet to connect Thunderbolt3 to a X300. StartTech should have a Thunderbolt3 to Thnderbolt2 converter in June ( https://www.startech.com/Cables/thunderbolt-3-cables/thunderbolt-3-usb-c-thunderbolt-adapter~TBT3TBTADAP ) But we would prefer to find a direct Thunderbolt3 to 10GbE SFP+ converter. If by any chance anyone finds such adapter, I'll be happy to buy/try one!
