All Strix Halo systems have two USB4 v1 ports (40GBit/s) that are also Thunderbolt 3 compatible.
If you connect Strix Halo systems using a Thunderbolt 3 cable, you should see a thunderbolt-net connection in NetworkManager rightaway. This will provide around 9 GBit/s of bandwidth.

There doesn't seem to be routing with thunderbolt-net, so with two ports you can connect three Strix Halo systems using for now. You can of course try to use other means to cluster more systems, like the Ethernet ports.

### Cabling
-
You need a cable that can handle 40 GBit/s. The cheapest cables that are known to work are "_UGOURD Thunderbolt 40gbps_" that you can usually get for less than $5 each at 0.3m length from AliExpress. Good luck!
