It would make for a good enough edge/home cluster node. Buy 5 of these, each with two SATA SSDs/HDDs, SFP+ uplink to cheap 10G switch [1], run k8s/k3s, might even be able to squeeze in Ceph.
2.5G switches are expensive and rare. If you want to make use of multiple links to an L2 ToR, you have to set up LACP which is annoying. You could do ECMP for L3 LB instead, but that requires an even more expensive switch.

EDIT: as for commitment, I'm literally looking to solve the problem of 'I want a low power k8s cluster, and I'm okay with a switch SPOF' for bgp.wtf's FMT location. If I could buy 5-6 of these, with 10G uplink, especially ready to rack, I'd probably order them today.
- arghwhat 6y ago10GBASE-T is not very popular and rather expensive, while NBASE-T (2.5/5G) is gaining traction for high speed consumer stuff. SFP+ is cheaper and better, but not exactly common in consumer networks where I imagine most low-cost ARM boards end up.
- q3k 6y agoThis is not an ARM board, though. I mean it's no powerhouse, but definitely good enough for cattle in production if you're budget constrained.
- arghwhat 6y agoYeah, but they offer what provides most utility for their intended target audience first and foremost, and SFP+ would be inconvenient there (especially as copper pluggables ain't free).
