Thank you for your ReplyDon't misunderstand me, or interpret the answer as arrogant, but yes, I am sure.Edit: Scratch that. I just realized, that I wrote port 3 (as I counted from the top), while in the Fujitsu documentation this is actually port "2". So, I am talking about the 1x4 port.
(About said 1x4 port):
It is a PCH port, which can be bifurcated through low-level settings in the Intel Flash Descriptor (first 4K of SPI storage space in the Boot SPI Flash). Also the Intel corresponding Intel "fitc" tool lets you modify it via a GUI.
You can then reconfigure the port to no longer be a 1x4 port, but rather a 2x2 (or maybe even 4x1; don't remember) port. And for a dual function Optane, like the H10 or H20, you will need a split port with 2x2.
As I said, as proof I had the mentioned Intel Optane running in there, with both of its functions active and working.
Edit: The two 1x8 ports are actually the already bifurcated PEG-slot. So, the 1x 16 PEG lanes, split into 2x8. Theoretically, one of those ports (which one, depends on the question of enabling lane reversal or not) could be further split into 2x4, as the PEG supports 1x8 and 2x4. This would need to be done via CPU Straps. See here: S/W strap for x16 or x8/x8 on PEG

Well, I expected them to have some "Logic" behind it. But I guess it's because the black PCIe Slot is actually only x1 Electrical or ?Sorry, but do you really think, that differentiation by color coding is a safe way of telling the connection type, when you can actually analyze the function in an OS or the EFI-shell?
It would have been better if they just did a Block Diagram in their Documentation like every other Motherboard Manufacturers on the Planet (e.g. Supermicro or even ASUS/ASRock Rack).
Of course you can say that Fujitsu didn't sell this as a Motherboard but rather a configurable complete System, but still ...
Uhm,A simple "lspci -t" in Linux will tell you where a device connection actually goes, port-wise. Very helpful stuff.
lspci -tv
(so you also get the Description in Text as well) works, but it does NOT tell you where the PCIe Slot goes (e.g. the Logical Mapping to e.g. PCIe Root Port XX will probably be different than the Silkscreen on the PCB or the "Slot XX" in the Manual), wouldn't it ?So how exactly does that Help you ? Trial & Error and keep moving the Card you have plugged in the Slot until you achieve the desired Output in
lspci -tv
, so you can reverse engineer their Layout ?Well, I haven't been proven wrong on that and also other People experienced the same. It's maybe NOT conclusive (hence the "Usual" Word) and I didn't test 300'000 different Motherboards Makes & Model, but on the Supermicro X10SLL* and X11SS* that I tested,"Usually" seems to be one of your favorite words. I would say that "usually" no recent Connect-X card with a recent firmware version has enabled ASPM, unless you somehow force it.
turbostat
/ powertop
would show PC6 Package C-State when plugged into a PCH/DMI/Chipset connected Slot.That was Mellanox ConnectX-4 LX with latest Firmware from Mellanox
Can it be a "Fake" / Buggy Reporting ? Possibly. Not sure if I checked the Kill-a-Watt Meter for those Test to see if the Power Consumption was close to Baseline.
But for sure with the Mellanox ConnectX-4 in a CPU connected PCIe Slot, it would NOT go below PC3.
It is a nice Choice, although more expensive and less available good Deals IMHO (especially in Europe)If you are looking for ASPM and 10G at the same time, then Intel X710 is a nice choice.
