I haven’t explored it beyond just seeing the outcome of plug-n-play. I’ve connected the one of the same aVolution Thunderbolt 3 disks to the controller using an active Thunderbolt 4 cable, but it doesn’t enumerate. If you’re interested in Thunderbolt 3, you can see some insane benchmarks using RAID-0 over here. Unfortunately, I don’t have a benchmark for this yet. The PCIe limitation of 4 lanes is likely the reason for this.
I do see twice the number of lanes as compared to the Thunderbolt 3 card ( I think): # cat # cat # cat rx_speed I still only see about 16.8 Gigabit/sec when using the Thunderbolt4 network interface: # iperf3 -c 10.10.10.2 I expect that since Centos 7 with Linux Kernel latest (at the time of this writing: 5.13.86_64) discovered the device, it should work in most Linux distributions with a newer linux kernel and fresh userspace tools. Here’s some other miscellaneous output: # cat # cat # cat # cat device_name I also looked at it visually with mc just for grins.
I parsed it through various tools ( od, strings, binwalk) but didn’t see anything notable. I grabbed a dump of the nvm firmware at /sys/bus/thunderbolt/devices/0-0/nvm_active0 using dd. Verbose output ( lspci -vvv) can be viewed here. | +-02.0-00.0 Intel Corporation Thunderbolt 4 USB Controller \-+-00.0 Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 DMI2 Here’s another pci tree view ( lspci -tv): 1 I’ll explore that further and document it eventually.

I’m going to install the connector with the pins shorted (ground tied?) to see if anything changes with regards to capability or recognized features. I wanted to visually inspect the pinouts before shorting the pins, hence why I took pictures and removed the cover plate (shroud).
I simply inserted the card into the server and booted it up. I did not need to short the pins on the TB_HEADER that I did in my previous post for the Titan Ridge card. Most relevant among them is the Intel Thunderbolt™ JHL8540 Controller IC:Īdditionally, the addition of a 100 Watt power delivery controller ( I think): Under the aluminum shroud, however, lay obvious differences. The actual form factor is identical, including the etching on the PCI brackets. The first thing I noticed about this card is that it’s nearly identical to it’s cousin, the Thunderbolt 3 Titan Ridge Card: I’ve captured a few thoughts, observations and pics here. As a follow up to my post about using Thunderbolt in a NAS, I recently bought a Gigabyte Maple Ridge Thunderbolt 4 add on card. I’ve been exploring Thunderbolt quite a bit lately.
