Freenas mini from 2016 motherboard c2750d4i replacement

TrueNAS General

I think my motherboard failed, won’t boot, no VGA output and can’t access a console screen via ipmi.

I’d like to replace with a modern board with equal performance and power consumption. This server just hosts photo prisim and serves as a backup. It’s hardly used really.

I want to replace the board with a brand new board that will fit in this chassis and use the same power supply. I’m currently using 4 of the sata ports for my zfs and then a 5th sata for the truenas os.

This thing just hangs out on my local network it’s not being accessed via the Internet.

What boards to folks recommend? Are there any guides for swapping this board out and ensuring I don’t lose my precious data? I don’t have a backup besides what the zfs setup is doing for me

Welcome to the likely c2000, avr54 bug club. I doubt you’ll get any help from Asrock rack at this point, so looking for a replacement is a good idea.

There is the c3958 super micro board that ixsystems uses now but it’s spendy. A better option may be the Ryzen 570 boards that Asrock makes now, one has onboard intel 550 intel 10GbE, the other does not.

What’s nice about these boards is that you can put in a CPU of choice to meet your needs, the two Oculinks can then be used for SATA today and NVME tomorrow (up to 8 drives).

Should be quite power efficient and still allow 10GbE operations if you want them.

It’s a mini-ITX board, so should be a drop-in replacement.

You should work on that.

Mini-ITX X10SDV boards fit nicely in a TrueNAS mini/Supermicro CSE-721.

If the “swiss” part means you’re in Switzerland, do not need 10GbE, do not mind importing from Germany and 3D-printing a backplate, a Gigabyte MJ11-EC1 from RAM-König could be a cheaper alternative (4 SATA + 4 from SFF-8654-4i with breakout cable).
(But :scream: price is on a sharp rise since Black Friday. This good deal is close to its end.)

The X10SDV boards can also use DDR4 RDIMMs, which are more reasonably-priced, particularly on the used market, than UDIMMs.

Sacré—bleu! That’s almost as heinous as Germans importing something from Switzerland! (lol)

No idea how customs work from the EU to the proud fortress-island of Switzerland…

You have to pay swiss VAT + a handling fee.

Same as in the other direction. That’s extra cost to factor in, when the strongest point of the (custom-crippled) MJ11-EC1 was being cheap (59.99 with the ATX adapter as of last week).

That’s a really good point in Europe where the de minimus tax / customs exemptions for cross-border transactions are much lower than in the USA.

As I understand it, the old US de minimus limit was $800 / package. That is what helped so many offshore companies when they can ship directly to us customers without having to set up a US operation, meet US energy efficiency or safety standards, pay import fees or taxes, etc.

Local companies on the other hand importing foreign parts en masse have to deal with import duties (though historically lower than 3%), collecting state sales taxes, and can be legally liable if something goes wrong.

A plumber acquaintance of mine found this out the hard way when he installed a customer-supplied faucet. My state has a license registry that most US-selling OEMs pay a nominal fee to include their wares. If the part is not on the list, it’s not legal for install here. When the faucet broke and flooded the house for a few days, his insurance asked for make and model, noticed it was not on the list, denied the claim, and then my acquaintance had to pay a couple of $100k out of company pocket to repair the damages.
