As long as it's not molded, should be fine. I had one catch fire on me and found that guy's videos a week or so after. It had been in my desktop machine for years, then one night, poof. Don't hang too many drives off of one run to the PS, either. Voltage sag can be a problem and cause drives to drop out of the array.

Nice!

Can also punch down a molex or SATA connector to suit as needed

Change the name of the VM

You can test the link itself with iperf

Those drives are known for terrible write performance

Try a brain dead reset on it https://www.apc.com/us/en/faqs/FA156611/

Also, make sure you spread the load over multiple runs from the PS to the drives. Don't hang them all off of 1 line with splitters.

May need to re-calibrate it https://www.apc.com/us/en/faqs/FA284198/

Here's a post to get you started

I've added 20mm fans to each card in the server just to be sure they'll stay cool and quiet. I left the stock cooler in place as the CPU isn't taxed very often or for very long when it is.

Depends on the controller, connections, cables - any communication problems and the drive will drop out of the array

I'd do the parity upgrade rebuild in maintenance mode just in case SHTF

Wouldn't explain the freezes, but worth investigating. I had a dodgy power button on my WMC box, it kept randomly (cleanly) shutting down in the middle of the night. Took a few months for me to figure out what was happening.

If you plan on using those for your unraid build, you're in for a world of pain. You need a proper enclosure and a HBA to address them. Using USB and/or eSATA multipliers isn't recommended as they'll just drop drives out of the array randomly if you get them all to show up at all.

You can disable it, but you may not be able to see the server shares show up under 'network' in Windows 10 clients, but you can still browse them manually by server name or IP

How old is the power supply?

FWIW- Last weekend I was troubleshooting an issue so I had to un-rack my server, and through sheer laziness left the USB thumb-drive hanging off the back. While re-racking, it snapped off.... I was back up in less than 20 minutes from download to re-installation.

Look at the specs https://www.asus.com/us/Motherboards/PRIME-X470-PRO/specifications/ the CPU has 20 PCIe 3.0 lanes, 16 for the two 16x slots (either one 16x full speed device like a GPU or two devices at 8x), then 4 lanes for storage via the m.2 slot. The chipset has 8 PCIe 2.0 lanes, 4 for the last 16x slot (it will run at 4x), 3 for the 1x slots and 2x for storage via the second m.2 slot but really only 1 is available So that's your budget, 28x - 1 or 2 GPUs will need 16x max total (16x for 1 or 8x times 2), HBAs need 8x for best throughput and that leaves you with 4x for a nic or m.2 drive, just remember the m.2 slots normally share PCIe lanes with other slots, so read the specs for available configuration options.

Both will run at 8x

I figured the same thing, "it's an 850W power supply, what could go wrong..."

This. I was having problems with drives dropping from the array, replaced HBAs, cables, drives, until I figured out there were voltage drops causing random drives to fall out of the array.

Do you have all of the 4224's backplanes plugged into 1 cable coming off of the power supply?

This worked for me

Not for that workload, you'd just be wasting power
