As I posted about wanting to make a 3-node high-availability cluster out of commodity USFF desktop PCs, I found this video outlining a 3-node Intel CPU cluster that runs on 10 watts of power! The cluster uses a SBC called a Zima Board that looks interesting – it’s got SATA, a PCI slot, and having an Intel CPU means less issues with cross-compiling to ARM and being able to run the same OS and binaries in my lab environment.
