  • Sounds like a great use case.

    I’m assuming your nearline drives speak SAS? Are you doing redundant controllers on the backplane for multipathing and for fault tolerance? I’m not sure if bcachefs specifically supports it (or if that would happen at a different layer) but distros in general should support it.

    TCO gets split into CAPEX and OPEX, so you come out ahead on the initial purchase even though it uses more power in the long run, which surely looks better to the business.













  • You’re running local storage for a VM host? Or are you talking more like whiteboxing your own NAS?

    I understand what bcachefs does. I’ve used bcache many years ago to do exactly what you’re describing, albeit for bare metal servers. I’m asking why.

    I’m just trying to understand what the use case would be in 2023 outside of a home lab, given that cost per gigabyte is basically at parity between SSDs and HDDs when you consider TCO (i.e. when you price in the extra power and cooling overhead for the HDDs, failure rates, and such).
