I'm in too with few probably. I bet they dump it for the older v3-v4 systems because of Scalable Xeons crazy prices. And now we face it :D
Yeah - the used CPU market for SP is not good to start with - thats not going to end well (cheap)

Yes I know, but is a 12:4 oversubcription necessary or would 12:2 suffice? And this is a PLX chip so does it actually get impacted by oversubscription?
Got you. I didn't realise there was any flexibility with the mapping - I assumed it was fixed 1:3

I don't know either way - have not had time to read the backplane manual :)

with 1 CPU you get 12x NVMe port usable. Right ?
Yes, that's correct. That block diagram only shows the onboard NVMe though (2 per proc). For this, 2 risers are used with 4 NVMe ports each which are multiplied to 12 each in the backplane

24 memory slots - finally a place to use all the NVDimms I dont have PowerGems for ;)

So I just had a call with the seller,
the 8 nvme ports for the backplane are provided by 2 nvme riser cards, there are no nvme ports onboard (my error), and there are 2 x16 slots free (one in each riser). I think they might have forgotten the x8 slot in the right Riser, but I am not sure its there.

The pics on the webpage are actual pictures of the boxes, the variation they are implying is just in case a customer buys add-in cards or add-ons.

On the X10 generation (2028U-TN24R4T+), you needed both risers to feed the backplane. There are 4 OCuLink cables per. They're pretty hard to come across on their own. The backplane, while one PCB, is split in half, so if you only run cables to one side, you're only going to be able to use 12 drives. This is a limitation of the PEX 8764 PCIe switches as they can only handle 64 lanes.

Same here from what I understood now. The misconception was that I had assumed that the board itself was also providing 4 NVMe ports

It does have the 4 OCuLink ports on the motherboard actually. The shipping configuration has the backplane going to the risers still. I'm not sure why Supermicro decided to do that instead of making more PCIe slots available on the risers.

For those who are in contact with the sellers, did you ask if they shipped to USA ? if so how much for shipping ?

Okay, Intel. It's clear now you don't want me to buy any newer CPUs. According to Intel Xeon E5-2690 v3 @ 2.60GHz vs Intel Xeon E5-2680 v3 @ 2.50GHz vs Intel Xeon Silver 4216 @ 2.10GHz [cpubenchmark.net] by PassMark Software - Xeon Silver 4216 is the closest adequate alternative to near-top E5 v3 CPUs and it costs five times more (and not that easy to get here in my country). I better wait when AMD kicks those $3-5k Gold and Platinum one's arses :D

Well, first I was fine with 2028U-TN24R4T and as far as I see from both systems parts list - why not to swap X11DPU with X10DRU, easily found on ebay for $150 no more for less than $400. But wait, the same seller has SuperMicro CSE-819U X10DRU-i 19" 1U 4x 3,5" LFF 2x Intel Xeon E5-2600 v3 v4 2x | eBay for a great price. The good thing - even after swap I'll have two complete systems but not just shiny alone new board for the shelf.

@zeynel did your barebone arrive yet?
Could you post some pictures of the riser cards or wich model it came with.

yes it's arrived, but we're moving my company. And I won't be able to get a closer look at the server for a few weeks.

Here you go

Extra riser one may need (was not included)

BTW, I've successfully swapped X10DRU-i+ MB here, what you need is regular GPU power cable or CBL-0333L-01 original part, because one from X11 does not fit.

So, all feedbacks are good ?
This box is very attractive (except costly scalable cpus) !

@Iaroslav, switching with the X10DRU-i+ was a pain or it was quite simple ?

On the different end of the MB side, does anyone know if the H11DSU-iN or H12DSU-iN would work with this case along with an AOC-SLG3-8E2P HH NVMe HBA? Would be great to try this with Epyc Rome ES CPUs

It was my first experience with ultra servers and the only issues were backplane powering cable for 2U chassis I mentioned earlier and few MB mounting points you need to move or apply custom spacer to fit X11DPU inside 1U. Don't forget about FANs to be replaced as well.
BTW I've got a pair of Xeon Silver 4109T's for $450 on eBay - not that fast to compete with v3-v4 solution, but still enough for some decent use cases.

That's maybe possible, as SC819UTS-R1K02P-A mentioned for H12DSU-iN | Motherboards | Super Micro Computer, Inc. also present in optimized chassis for X11DPU-XLL | Motherboards | Products | Super Micro Computer, Inc.
