THIS WHOLE 3-NODE CLUSTER RUNS PROXMOX, CEPH AND KUBERNETES - ON 10 WATTS TOTAL.
that clip is three zima boards wired to one little switch, and the power meter reads 10 watts for the entire thing.
on those three tiny fanless boards:
proxmox running a real cluster, three nodes as one datacenter
ceph spreading storage across all three, so a node can die and your data doesn't
kubernetes on top, kube1/2/3, plus docker and high-availability failover
this is the exact stack that runs in datacenters, shrunk onto a shelf.
kill one node and the vms migrate to the other two. it heals itself.
and it pulls less power than a light bulb.
no server rack, no cooling, no power bill you'd ever notice.
the uncomfortable part isn't that it's small. it's that "enterprise infrastructure" was mostly the rack and the noise, and none of that was the actual capability.
