skip the Cache Drive and use 2 Drives for the main OS, if you can get ECC as 20TB’s is a lot of data if something goes wrong, and like other file systems ZFS will destroy your data with bad RAM.
Microsoft did us dirty with the Bootloaders/UEFI’s we have now so why not.
I think it was 66~ watts for my Layer 3 8 port 10Gb switch, and Router in use.
they do make some good hardware, just this one they cheaped out on and used 16MB’s of Storage, it really hobbled the device.
The one i linked is both a router and or switch, you can get cheap switches for like $300 that do really well.
many people just buy junk like this https://www.amazon.com/Mikrotik-Router-Switch-CRS305-CRS305-1G-4S/dp/B08437RDM1 it’s cheaper in the long run.
You will need a good 10Gb nic, I have been using Intel nic’s if you use a Intrusion Prevention System that can eat away at the CPU, also more RAM helps like 8GB’s or more for IPS, I use 16GB’s for IPS + ZFS and a nice Switch can help a lot as it can do DNS and the works, more or less i use a firewall box to a Switch and use a Layer 3 Switch for routing, some can do 20+Gb’s routing.
this is what i do, i look it up on the firmware selector and go from there.
on my NAS i do and work data as well.
encrypted separately like by album you can, even have rclone change the name and use hashes then it does not matter what you use long as they’re keep your data safe. also it is best to keep a copy in the EU and US if you can.
I been using TP-Link Matter junk with Home Assistant.
Proxmox, TrueNAS, Debian with cockpit etc. really any type 1 hyperviser work’s.
Maybe your HBA is having issues? or a Drive is Failing? have you done a memtest? you may need to do system wide tests, it can even be a PSU failing or a software Bug.
also TrueNAS is built with Docker they use it heavily something like 106 apps, Debian has good ZFS support, but you will end up doing a lot of unneeded work using Debian unless you keep it simple.
ZFS is by far the best just use TrueNAS, Ubuntu is crap at supporting ZFS, also only set your pool’s VDEV 6-8 wide.
TrueNAS, and Debian
Use a VPN to check for a bottleneck, my ISP will cap my downloads from Steam to 10MB/s with a shitty VPN i get 25+MB/s.
Read the Docs they even say if Ram has corruption issues it will nuke your data, even if the CPU is having issues it will nuke your data.
