I've got 4 of these in a proxmox cluster and they are quite decent. My only complaint so far is some weird behaviour out of the usb4 interfaces trying to setup a redundant ring type network with openfabric frr. Speed was great node to node but for the 4 paths that require traversing a node speeds go to 1.5ish MB/sec which makes it unusable. I'm hoping a kernel update comes out with a fix for whatever bug is causing that.
