Just a heads up for anyone looking into building a small, low power NAS.
There are a good amount of X10SDV-4C-TLN2F available on ebay right now out of China for around 250 USD.
Just picked one up 
That’s a mini-ITX board, isn’t it? Tariffs?
yes, mini ITX
Tariffs probably yes if you are in the states.
Tempting. And I don’t even have an immediate use for it. The F in the model number should mean it has IPMI too, and as a X10 board that should include a HTML5 remote console. Confirmed:
This one lists US$3 for shipping, saying no additional import fees would apply:

me neither 
And, for quite some time, there have been a lot of X10SDV-16C-TLN2F for $340, if you want a high core/low clock virtualisation server.
As a very temporary opportunity, European users can even find a pair of X10SDV installed in Supermicro “Cube” 721Q chassis.
Thanks! Looking into it.
My 8 core X10SDV is still rocking with its 132TB of storage 
Great little NAS boards.
And full bifurcation support too.
Put 3 M.2s and a lntel Arc GPU in with the 8x4x4 adapter.
128GB of ECC support too.
I have two, really pleased.One of them came locked with a password that took some doing.
But look for the C+ (with a fan), v2.00 (with two fan headers in the corner, not one), and consider a 4F rather than a 2F. So far as I know the 10G network adapters can negotiate 1G or 10G, but not 2.5 or 5. The 10G adapters are higher power but can be switched off. Also, the high core versions are 65w, while the 4C/8T are 35w. If you are thinking about power.
X10SDV Rev.1 boards are those with D-1520 or D-1540; anything else is a Rev.2.
Rather than a C+, I’d suggest to get one with a passive heatsink and put a Noctua NF-A4x25 on top: It will be totally silent while the + fan makes a high-pitch whine.
Just received mine yesterday. Slight discrepancy, in that it was listed as a C and I received a C+. Also arrived without the CMOS battery, which is of course easy enough to fix.
I’m wondering what would be the best way to connect it to u.2 drives. I don’t know that I’ll go this direction, as they’re pricey, but the largest m.2 drives I’ve seen are 8 TB, while I’ve seen 16 TB in u.2. And AIUI, u.2 is just a different physical interface for NVMe.
So it’d seem in principle that there ought to be a card like this:
…but with cables for u.2 rather than m.2 sockets, and without requiring an (expensive) PCI switch (since the mobo supports bifurcation). Any ideas? I’m not really sure what terms to even be searching for on that.
What about this ?
I received an C+ board to btw.
That, or rather the Shenzhen equivalent (Reichelt pricing is… 
), or the cabled version. That should be enough for PCIe 3.0, the main issue being cooling these U.2 drives.
For PCIe 4.0, you’d probably want some active component in there.
That looks like just the thing, though I rather like the idea of the “Shenzhen equivalent” based on the pricing noted at the other link. The board itself is only PCIe 3.0, so it doesn’t seem like a gen4 adapter would be called for.
I think this is what I’d use:
I see this board supports BIOS updates via IPMI (you don’t even have to have RAM installed), but requires a license key in order to do so. To generate your own, see:
Hero!
I used web sites of dubious reputation until now. This is going to go into a shell script and in my private git repo.
Does not work with X12 (and probably newer). But these come with BIOS updates via IPMI without any additional license 
I finally got around to putting it into my Joplin notes–I’ve been relying on searching the forums up to this point. Finding/remembering the exact terms to search for is a little dicey, as you might imagine.
But it worked again last night. You’ve probably already figured out that you enter the MAC address without the colons.
My xxd here ignores them. I checked with the licenses I bought over the years and I got the identical keys.
Guess I’ll use it as an opportunity to practice some python. I want to be able to enter an arbitrary number of MAC addresses and get nicely formatted tabular output.
Thanks again.
