K4NZ1 Posted November 27, 2022 Share Posted November 27, 2022 Hello people, What components can you currently recommend to create a powerful home server as energy efficient as possible? I've only had Unraid for a few days and am very excited about it, but I'm only running it on a small Lenovo ThinkCentre M900. But I would like to use something bigger to be able to use more hard drives and thought here about 5-6 HDD's + 1x NVME as cache. Currently I use PiHole, Swag, Uptime Kuma and Nextcloud on the small thing but would like to use a few more things. Here I think of something like a picture gallery for my photos (hobby Fotorgraf) and music, backups, etc.. I would also like to use something like Jellyfin or Plex and possibly run one or the other game server (Minecraft, etc.). I would be happy about some recommendations, tips and more. Kind regards Quote Link to comment
aburgesser Posted December 7, 2022 Share Posted December 7, 2022 Energy efficiency is often in opposition with power, and is affected by several factors: Workload: all else being equal doing more will take more power. Especially long running/frequent workloads that stop the race to idle. Architecture: newer process nodes tend to have better efficiency metrics. Peripherals: any PCB not contributing to your use case detracts from efficiency. This applies to motherboards (ITX > mATX > ATX typically). Number and type of drives affects this. Also don't forget to run the server headless. Downtime: spin downs and scheduled sleep cycles will reduce power needs at the cost of availability. If you want a lazy route to a powerful server that is fairly efficient: Workstation ITX motherboard with Intel I3/Xeon CPU (IGPU for HW transcoding) of recent architecture No expansion cards 16-32 GB RAM 1 NVME cache drive, 1 parity drive, 2-4 array drives. Array drives should be 5400 RPM class. If you want to take it a step further you need some uncommon components. There is a community somewhere on reddit that tracks low power Unraid builds.
