  • I use a similar Dell Optiplex 7000 series.

    It boots from the NVME, with an 8TB 3.5 disc for data, and a 500GB SD for my VMs. (Since spinning disks can idle much lower than SSD, getting my always-on VMs off the big drive lets it idle, with the SSD peak power being lower than the peak of spinning disk Adding the SSD increased net power slightly).

    I use a splitter on the 12v power line for both of the drives. It’s fine.

    This box only has an 80w power supply, and with both those drives hooked up it draws 20w at idle, and peaks at 70w when converting multiple videos simultaneously.

    The manuall tells you what you can do without voiding the warranty.

    Edit: Given it’s age, I’d pull the CPU cooler and replace the paste. It’s likely hardened by now. Mine was randomly rebooting because the cpu would overheat. Replaced the thermal paste and its been rock solid since.




  • The number one thing you can do, by orders of magnitude, is to start with power-friendly hardware.

    For example, my previous server was an old gaming machine. It’s lowest idle power consumption was 80 watts. That was with running an OS that permitted heavy power reduction control, and enabling every power saving feature in the BIOS.

    Compare that to my 2019 Dell Optiplex Small-Form-Factor desktop I’m running as a server. The power supply is rated for 80 watts, MAX. It idles at 20w, peaks at about 70w when converting multiple videos simultaneously. This with an 8 TB enterprise drive for data.

    So 1/4 the power draw when idle, where it spends perhaps 90%+ of its time. Even things like Resilio Sync and Syncthing don’t significantly raise CPU time.

    Streaming with Jellyfin or Mediamonkey have nearly no CPU impact.

    There’s nothing in heavier hardware you could tune to get down to 20w.




  • RAID isn’t data redundancy, it’s an array of drives combined to form a single logical storage pool. It solves the problem of needing a single storage pool larger than the available drives. As such, it’s very sensitive to loss of a single drive.

    At your storage size requirements (2 TB), RAID is unnecessary today.

    Edit: Let me say it again for you downvoters-RAID is NOT data redundancy.

    There is only ONE copy of your data in RAID (excepting mirroring). It’s why RAID now has double parity and hot spare drive capability.

    RAID is for creating a single pool that’s larger than available drive size.

    Go ahead and downvote in ignorance, and learn about data redundancy when your RAID fails.

    RAID is NOT data redundancy - it’s DRIVE redundancy.

  • Others have mentioned backup, I’m going to reiterate that.

    Backup, backup, backup.

    I have an (old) NAS that frankly I don’t trust to not die. Then again, anything can die, so it’s just one component of my data duplication.

    I also have my server which is authoritative for all data, which is then duplicated (on schedules) to the NAS and 2 external drives, so I have 4 local copies.

    All mobile devices sync important data to my server.

    Power

    My NAS idles about 15w. It’s 5 drives, so honestly that’s quite low and tells us it spins down drives.

    My server idles at 20w, using NVME as the boot drive, a large data drive, and an SSD for virtual machines. It’s power supply maxes at 80w (which it approaches when I’m converting videos with handbrake).

    Before this my server was an old gaming desktop that idled around 100w.

    So my server today is a 5 year old Small-Form-Factor Desktop that I picked up for $50. I paid more for the RAM I added. It has enough room internally for one 3.5" drive and the 2.5" SSD…

    It’s also quiet - the CPU and power supply fans double as case fans.











  • Uggh, feel bad for them.

    I’ve tried for years to get friends and family to have their data sit in a single point in the house and use backup services. That would be a massive improvement.

    Family won’t listen, so I’m building minicomputers for them all that will handle it. Just have to configure their devices to store data there.

    This started because one sibling asked about transferring photos from a phone, and I started documenting how to use Resilio and Syncthing.
