To host my ever-growing collection of pet projects, home automation, media management, and site hosting, I designed and built a “highly available” (highly available enough for me) kubernetes/ceph cluster using 7 low-power arm64 nodes, each with their own redundant storage and redundant battery backup. The case for the system is made from laser-cut walnut, PVC, and standard threaded rod from McMaster-Carr. It automatically connects to the city WIFI and tunnels to a cloud server if it ever sees home connection down. Though completely overbuilt, it gives me the perfect home test-bench for networking and infrastructure.
