The linux implementation is quite poor. Among other issues, your answer is linux treats it as a TCP/IP link- so packets don't have any offloading for checksums, etc. it's also incomplete (ex- you have to physically unplug and replug the cord every time one side loses link- even a reboot).
This is my firsthand experence trying to get some tablet motherboards to link up and work as a proxmox cluster w/ TB3 as the link between nodes.
I have a 3 node proxmox setup on MS-01s using a 25G Thunderbolt ring for Ceph, and indeed it took a lot of hoops to get it working correctly and reliably. I did manage to get it such that nodes can go up and down without needing to unplug anything, and the dynamic routing works if a node disappears. Performance is pretty good, with a more realistic 20ish gbit/sec.
AWESOME!! Do you mind linking references? I put the project aside because of these issues.
Yea I'll dig up the link I used - there was a great reference about getting the thunderbolt working after reboots/etc.
I figured this was Jeff’s CTO Laboratory. I enjoy your channel. Are you kicking yourself for pulling the trigger on MS-01s now that MS-02 Ultras released?
Yea! Those MS-O2s look great, so I may need to upgrade! I did get a couple of DGX Sparks to play with.
