I m not expert of docker network, but interest on what other people doing and why need preserve custom network, in first, I m thinking does any VPN plugin / docker cause problem. Anyway you found another solution, btw due to I put docker path to /tmp so every reboot need re-download all docker, that may help fix some hidden issue. And I also apply VLAN to separate stuff for what I need.

My first HA VM was use official qcow2 image, just need to note if you change the XML then you need manual config image type to qcow2 again. I just restore the backup from Raspberry then migrate finish. https://www.home-assistant.io/installation/linux

But still no report for testing from @bing281 and JorgeB estimate min. throughput down 73MB/s per disk.

If that, does it make conflict ? What special of that custom networks must preserve and no other method to eliminate it.

Thats great, but do you have UPS ? For non-UPS protect system, I will config limit / minimize continue writing ( i.e. security camera recording ) to one NVMe / disks instead most of storage. This will major prevent FS corruption in suddenly power off. This not a problem if you never mind the warning. I like btrfs more then ZFS, mainly bcz better performance. That depends on what capacity you need and how you define pool / array is main / backup. For me, I use array as backup tier, but it also share for some user because array has better user access control. As I want to transfer file quickly, so pool are 1st place to store file then periodic sync to array. ( I don't like mover design, so array and pool always independent )

In longtime ago, I also use USB enclosure for the build, I buy two different 5 bays enclosure, the first one never reliable and the 2nd one finally reliable by adding a USB hub ( dedicate chips ) and change the firmware of the enclosure. Both enclosure architecture are USB to SATA phy + port multipler but they use different chips solution. Nowadays, some USB enclosure use different architecture, they are USB to USB hub + multiple USB-SATA phys, this may be more reliable, but still many issue could cause problem. In simple say, you could try adding USB 3.X hub in between and test any different.

You should provide more detail how they connect, does all running long cable in SATA protocol so cause error ? If that, you can fix it by make them in SAS protocol in all long path, only last mile in SATA. With connect HBA to SAS expander, then this path will be SAS and support long distance < 10m, in each enclosure then fan-out from expander to SATA harddisk will be SATA and make them shorter then 1m. Next was rack disk swap case, rack case have backplane, so it eliminate mass power cabling to power up all disks. But also due to backplane only have small area to passthrough air flow, so it very hard to cool well even you putting 3000rpm or high pressure fan for cooling. I build in two box, it is a 3U expander (w mobo) case + 2U raw case (disk only), I add a expander ace-82885t in 2U enclosure and use one 8644 cable ( 50cm ) to connect them, the HBA are 9300-4i4e. It have different generation, the first version use two 9211-8i, one for internal and one for external, the external use a pair 8087 2m cable and IBM expander for the 2U path. The second version was 9211-8i + 1000-8e .... and currently only use one 9300-4i4e.

Yes, /sys/class/ path should better I also make some test on my fan, low range dead zone was 15 ( 328rpm, lower then 15 will be 0rpm ) and no high range dead zone ( 3000rpm ) .... but this should be fan spec. related.

I never found Unraid will control FAN PWM, I also make adjustment on PWM by user script, just simple set the value and no fluctuation. But the path different as you, you may try echo 1 > /sys/devices/platform/f71882fg.656/pwm1_enable echo 32 > /sys/devices/platform/f71882fg.656/pwm1 echo 1 > /sys/devices/platform/nct6775.656/hwmon/hwmon1/pwm1_enable echo $rpm > /sys/devices/platform/nct6775.656/hwmon/hwmon1/pwm1

Unraid CPU is 9700K, in longtime ago test, both directions got near 10Gbps result. No matter real-virtual or virtual-virtual. Haven't much idea currently.

My router have a feature name "WAN IP Alias" and I never aware that, it is something like you can add a virtual IP to your WAN. With those WAN IPs, you can open port and loop back to local. The advantage was it so easy for routing different subnet / vlan traffic to local, the drawback was source IP will change to WAN IP then you can't identify the traffic from which local client. With "IP alias", you can set additional IP under WAN I/F, then when you access those Internet IP, it will route to your local service. Because I limit the source IP must be same as alias, so basically no Internet traffic will route to local. With those setting, now I can - Access 192.168.6.6 "WAN IP" to different service which host in other subnet, even actual WAN IP change, I don't need change again. - Traditional DNS resolve to 8.8.8.8 / 9.9.9.9 will redirect to local DNS ( 192.168.2.5 ) - Once local DNS down or maintenance, I can simple disable the alias, then those traffic will go to Internet as usual. Now you will found 8.8.8.8 and 9.9.9.9 record in your DNS server. I also add other DNS traffic ( i.e. DNS resolve not follow DNS setting ) to local too.

Longtime haven't test, I got similar result, btw try different setting ..... got best iperf3 in virtual environment top at 5Gbps, reverse mode usually got higher result.

Pls setting SMB Security to "public" for troubleshooting first.

RAM really doesn't use lot of power, you would found even single phase power circuit would be enough, but if you add some voltage to it, then power will raise dramatically but still neglectable if compare to CPU power usage. For CPU, it also same, the pkg power was low because CPU run in minimal working voltage. I never concern deep C-states, I usually focus on those power hungry appliances, i.e. air-conditioner, heater etc. Take over control its cool on / off by automation have saving more.

Unraid can't confirm does the drive already zeroed even it have signatures. So designer will keep zeroing to the end ..... But you can decide to stop or not.
