    I think I will choose maybe an Intel I3 9th... to be confirmed.

    Get i3-10th gen :)

    Probably a 300W, juste need to find the exact model.

    Be!Quiet TFX 300W 80 Gold this is what I tested. Small and actually quiet despite how small fan is there.

  • OMV into Proxmox, low writing rate

    Quote from ik3umt

    Yes OMV is built over Debian, so I think all the network stack (not managed by GUI) has to be managed at machine level ,

    yes it can but then you have to fiddle with omv to not break your config if you accidentally touch it in gui, because OMV doesn't care and doesn't check, just overwrite! You'd need to manually add additional settings to omv to preserve your configs.

    And then it's a problem because if you have custom configs on network, you can't use them in other places so you're kind of stuck.

    Long story short, if you're network is anything bigger than simple one lan few simple nics? Stay away from OMV.

  • OMV into Proxmox, low writing rate

    ik3umt one side to note, strongly rethink putting OMV on a bare machine, do this only if you have straightforward networking, no vlans, virtual nics etc, otherwise you'll need to learn about salt states in omv so it won't overwrite your netplan configs as OMV doesn't provide any gui for this and it will be a pain - trust me, have this problem now, thinking about moving out from OMV from bare machine.

    I went from Intel J4105 series into normal motherboard. The J4105 series are very power efficient but I had problems with it, can't remember what. Now I'm on Intel 10th gen CPU, ITX motherboard with B460M and believe me or not, the power consumption in idle is the same. The only diff is max power. J4105 maxed at around 25W if I remember correctly. Current system MAX is around 65W. Yep quite big difference but also quite big performance difference.

    As a side bonus I got:

    - max 64GB of memory support

    - 4 sata ports (3 if I use M.2 ultra socket)

    - 2 M.2 slots (one is vertical and there's WiFi card)

    - PCI Express 3.0 x16 with SSD Boot support

    The J4105 had:

    1x PCIe 2.0, 2 x sata, 1 x M2, max 16GB of mem support official but I had there 16GB in one slot and it was fine, the same were reported by other peoples in the comments.


    The key here is the power supply. You don't need anything big, actually the bigger the power supply, the higher the energy bills because of efficiency.

    So for this setup a 300W PSU with Gold 80 certificate would be way than enough. Sadly I already had 400W 80 bronze which I'm using. But I did a test and could get even 1W lower with mentioned smaller PSU. Which is huge difference cause the system without HDD was "idling" at 10W so 9W is possible as you can see. J4105 was the same!

    And by idling I mean running 3 virtual machines :)


    One information for picking up motherboards, stay away from MSI! Their products has track of power efficiency issues, you most likely won't be able to achieve such low results with these motherboard. Also stay away from the lowest tier motherboard chipsets as also from the higher end ones. The low ones doesn't provide enough tweaking capabilities so it's possible you won't be able to get low C-states which are crucial to get low power while the high end top ones are meant for performance so you probably understand. And also ATX mainboards draw usually more power than ITX and mATX ones.


    Also check out the status with AMD, year ago it was kind of impossible to get so low with their CPUs under Linux, but I remember some information that new kernel should improve this, you have to search the network if that's fixed. This is why I had to pick up Intel :( Otherwise would go with AMD for ECC but it's tricky to pick up proper hardware for that.

  • Encryption - Do you encrypt the data on the disks?

    just switch to FDE (Full Disk Encryption) and you don't need to restart merger fs etc.
    In my case with FDE I got arond 100MB/s over WiFI. Yes, I'm already on WiFi AX.

  • Encryption - Do you encrypt the data on the disks?

    Quote from B3rnd

    My Raspi4 has an Ethernet Gigabit network adapter and it can easily manage up to 100 MegaByte/sec on the network.

    yeah and it's max (in tests it's around 110MB/s. With full 1gbps it should go around 125MB/s. One may say that it's only 15MB/s but then please use this to calculate how big is the difference when transferring 40GB file and more.

    On reddit someone mention that he got 70MB/s with RPi4 with Luks encrypted hdd during write. So it's way less than even that 110MB/s.

    here are some benchmarks that mention issues while copying onto PI with RAID0.

    but I chose the 5600G for low power

    the problem with 5600G is that it's hard to get low power with it under Linux. If I'm reading properly on some other forum it's a problem to reach low c-states on Linux. On Windows it's a different story. It should improve with never kernel but the 6.0 is not yet capable of doing this. In this case Skylake would do much better even below 10W!. Checking the posts it seems the best possible is around 20W. While with Intel 12th gen you get around 12W with some cheap normal ATX PSU.

  • How to bind WEBUI to specific network interface

    Quote from ryecoaaron

    There isn't a way to add saltstack code without hardcoding the mac addresses. At that point, you might as well just maintain the netplan files.

    that's not a problem to hardcode macaddress there. In the end it must be somewhere. The thing is that I'm trying to understand what are the incoming values I can use in that salttack so I can properly play with that. Normally I'd use that command I mentioned in that post but it's not working so I don't know what's available.

    Sorry, I cant tell, I dont have a kill-a-watt meter. This system replaced a setup with a Skylake Xeon (65w model) and 6x4TB HDDs, so I assume its much less than my old setup.

    you probably saved something on disks but I wonder how it is with that amd.

  • How to bind WEBUI to specific network interface

    Quote from ryecoaaron

    So, instead of just maintaining your own netplan files to fix the mac address/vlan issue and not using the omv web interface for network interface/bond/etc setup, you would switch to cockpit?

    Kind of yeah, since the slatsack cause me some problems which I asked in other post and I'm kind of stuck. And manually playing with netplan means that I would need again to manual play with the virsh which is something I don't want to do. Here is the relevant info:

    RE: Under what conditions OMV will overwrite netplan configuration files
    Regarding Salt,
    there's this file:
    /srv/salt/omv/deploy/systemd-networkd/50vlan.sls
    now I see the loop iterating over interfaces.
    According to the docs https://docs.openmediavault.or…html#the-saltstack-states
    I should make a state file
    so in this case would I need to make 60vlan.sls and inside of it I should hardcode changes for each vlan I have?
    or modify the 50vlan.sls and hmm I'd prefer to use the simple if condition but I'm unable to print the grains since the salt command is missing.
    I can't do …

    I guess that is a nice feature of OpenWR

    I'd say it's a lifesaver.
