Your Unraid server shouldn't be exposed to the internet, anyway, so why bother?

Don't use those. You'd need them too read 100% correctly to rebuild the array, should you ever need to. There's a reason why it's a Pre-Fail notice lol, it's failing.

FWIW- in the US they still have to honor the warranty (and they do)

I use the PR1500LCDRT2U now for the server/network I have always had a surge suppressor in the main panel, and another in the sub-panel. Fat lot of good they do lol. I suspect the first surge was a near lighting strike that induced a charge on my security camera's video line, back to the security DVR (which fried) and sent a surge down the connected HDMI to my AVR which then passed it along to my projector. In all, about a $5,000 hit - tho both the projector and AVR were replaced/repaired under warranty. No idea where the second one came from, it only made my HDMI ports go screwy this time. When I replaced my security system with POE cameras, I connected the switch via fiber to the rest of the network, so no chance of it passing it beyond the cameras.

Anecdotally, I stay away from APC after a couple of bad experiences - one of the BR1500Gs I had protecting my server failed spectacularly, one of the power transistors exploded (literally) filling the room with smoke as it continued to try and operate. Luckily, someone was home to yank the plug. The replacement (brand new) BR1500G failed in less than a year. I do still have a few NS1080's protecting desktops and AVR, tho. No issues with those so far, except surges have taken out the AVR, twice. Haven't been able to specifically blame the UPS for not stopping the surge(s), tho, as it could have come in from a different path. I put a LE1200 behind the UPS and the AVR still got popped a second time. YMMV

My Cyberpower PR1500LCDRT2U works fine with apcupsd

It wouldn't be twice the cost, it would be more like 5-10 times. Logistics is a key factor driving costs for all products - lithium batteries in that kind of density could never be shipped air, and limited in weight when shipping ground. Special circuitry would need to be incorporated into the design and a bunch of testing performed before it's even allowed to ship ground. It's just impractical for consumer goods. And that's before you factor in the cost of the battery itself.

Cost, and they're a pain in the rear to ship

If the UPS uses MOVs for suppression, those do wear out

Yeah, they have gotten expensive, I paid $85 new back in 2018! In a nutshell, VT-d allows for directed I/O, which allows hardware to be assigned to VMs The Mellanox cards work fine, but you'll need at least an x4 PCIe slot free Depending on the number of drives, you may need to keep the controller on an x8 lane or your parity checks will suffer - and I'd stay way from that marvel controller on the board.

The CPU will be the limiting factor, here: No VT-d means no pass-through (this is the downside of the early K processors) PCIe is limited to 1 x16, or 2x8, or 1x8 and 2x4 If you source a different non-K variant, your setup should be fine - get an Intel expander, no slot needed as it can be powered by a molex connector - res2sv240

You can try the 5e before you pull 6A - you'd be surprised how much it can carry

You are unlikely to saturate a 10G link, so putting everything on the 10G network and reducing complexity by eliminating the teamed 1G connections is your best bet

Or add SATA power connectors to the standard 4 pin line that came with your PSU, similar to this https://www.ebay.com/itm/20Pcs-SATA-Punch-Down-Power-Plug-Connector-for-ATX-PSU-IDE-SATA-Hard-DrivYJUS/303565748716 Have a multi-meter handy to verify continuity, but it's pretty simple

In the US, shucked drives will be covered regardless (unless you damaged it during shucking), don't even need to put it back in the enclosure - not sure how you guys handle it in Europe FWIW - WD shows it in warranty until July 2022
