Wait… so you connected the bifurcation AIC to 4 cables which were connected to drives at the other end to test the Broadcom cables or you simply put the drives into the AIC? The latter is sure to work. The former is what’s in question.
Thank you for summarizing everything thus far. I really appreciate it.
I think that they are done for the evening on my end. Lets see how tomorrow goes.
I use several of these too. Great units!
Earlier, I was starting to wonder if the tech was confusing the 9500 tri-mode with the P411W-32P. Particularly so when tri-mode backplane was mentioned. I’ll find out tomorrow. Hopefully…
I’d be curious to hear about that. One way to perhaps test that would be with a completely passive add-in card.
I’m willing to wager that there are some pretty potent re-drivers/re-timers card side though.
When using a P411W-32P, HighPoint SFF-8654 to U.2 SFF-8639 Cables, an Icy Dock EZConvert MB705M2P-B, and a Samsung 980 Pro;
I can confirm that I get PCIE 4 speeds. However, I have yet to verify the generation or lack of errors. Best case - No Errors. Worst case - Error rate is low enough that transfer rate isn’t negatively impacted.
I have one of these too!
AFAIK, it is completely passive aside from dropping the voltage to a usable level for SSDs.
I’ll be able to verify your results hopefully later this week.
I think what he was trying to say that he plugged the SSDs straight into the Asus AIC, and that, straight into the motherboard.
Either there’s a way to see the PCIE errors the P411W-32P detects and no-one here is aware how to see the reported errors, or the P411W-32P just silently corrects them. On windows in the device manager, there is a report of AER supported by the P411W-32P. There is a screen cap of the feature higher up in the thread.
I’d love to see if there are errors being caught, reported, and fixed.

The example with the passive ASUS 4 x M.2 PCIe Gen4 bifurcation AIC was just to show that it isn’t IMPOSSIBLE to run PCIe Gen4 SSDs with “unnecessary” passive adapters without getting PCIe Bus Errors. The M.2 SSDs were installed directly in that card, no cables involved but naturally this still causes a tiny amount of signal quality degradation.
Of course this becomes much harder as soon as cables of any length are involved.
You have got to be kidding me!!!
So the firmware that we have been using already…?

To be sure you can compare the checksums of the two firmwares with the seemingly same version. I wouldn’t put it past them to forget to update their versions, wouldn’t be surprised about file names like “Firmware_Version_1.2.3_really_fixed_2_tested_for_user_4 (3)”…
Otherwise I’m “glad” I’m not the only one BSoDcom is messing with.
Maybe they outsourced their Tech Support to Troll Trace:
I checked the url the provided against the one posted to the product page.
It is the same through and through.
Just to be certain though…

It looks like they (Broadcom) will be in discussion for a week or two before coming to a conclusion about the next steps for the firmware.

I asked on your behalf:
“When used in workstations & the system is put to sleep and then awoken, a BSOD occurs when writes are directed towards devices attached to the P411W-32P.”

Anyone bought/tested the Lenovo 4C57A65446 retimer card?
Any reason this wouldnt work in Asus WRX80 SAGE Motherboard? Considering that card or the linkreal LRNV9F24 retimer card:
Shenzhen Lianrui Information Technology Co., Ltd. Has anyone tested this one and had success with Gen4 PCIe U.2 Drives?
I have a really right build and the supermicro card is just a touch too long or I would jump on that.

Welcome to the community!
Unfortunately not myself, the only active regular PCIe slot AICs I have tried are ones with PCIe Switches.
If it matters to you, be aware that with simple ReDriver/ReTimer AICs you might not be able to hot-plug drives but have to do a complete power cycle of the whole system.
If you check out that AIC please write a short comment here about your experiences.
Maybe I should start a PayPal/Patreon for PCIe adapter experimentation then I might be less hesitant to check out stuff I haven’t looked at in this thread yet.
Thanks!
Hot Plug is not much of a concern for me but appreciate the heads up. If no one can confirm if it works I will assume the role of guinea pig and I will try and get hold of the Linkreal adapter and report back. No need for the Patreon.
This has been a very useful thread to help plan my build and has probably saved me from more than a few expensive mistakes…

I run my 2 P5800x via Adaptec HBA Ultra 1200P-32i PCIe card. The drives are then presented as scsi devices to the OS.

Can you run benchmarks to differentiate the emulated SCSI protocol compared to a direct connection with native NVMe?
I don’t have the connector that Wendell presented in the video so I can’t test direct PCIe connection.
Here’s my try at benchmarking 
I can’t test the raw device, as the drive is in use, so I have to create an LVM volume.

Update time!!
Time for every one who has one of these to reach out and give them an earful.

It’s almost comical how Broadcom seems to really take every step with the intention of showing how you should not handle such issues.
Do they reimburse you for the expensive Broadcom cables they sold to be able to use directly connected SSDs?
Has this reached a level to make a dedicated video about Broadcom? Maybe other models not only the three HBAs I could check (9400-8i8e, 9500-16i and P411W-32P) have been messed up as well.
Broadcom unfortunately still enjoys the reputation from their HBAs’ LSI days being recommended as the “gold standard”, which needs to change in my opinion since Broadcom obviously doesn’t care about the actual quality of their products.

I have my own “lulwut” support ticket running parallel and… I can only think that whoever owns broadcom must be winding them down or something… its the only thing that makes sense
or possibly they are going to roll them up to only sell to amd, nvida, intel, dell, hp, lenovo, quanta and like 3 ish other companies. no unwashed masses of end-users.
its the only thing that makes sense.

Hi, I wonder if anyone knows anything about some PEX 8717 PCIe Gen 3 switches I found while browsing the Taiwanese website shopee. There are no markings on the board.
Search for “PEX 8717, PCI Express Gen 3 Switch, 16 Lanes, PCI-E Card”
The title doesn’t match the product. It seems to be a 4x PCIe lane to 2x 4x PCIe lane device.
I’ve never seen anything interesting (internal development e-waste from tech companies) before show up on shopee before, so I don’t recommend making browsing this site a habit.
Each card has a 4x PCIe connector, which splits to 2x miniHDMI… I assume it’s miniHDMI. I assume each miniHDMI cable carries 4x PCIe lanes + the PCIe clock… but I’m not sure how well that works. I have no idea what sort of daughter board they would connect to; the seller doesn’t have any other hardware. It would take a considerable amount of reverse engineering to figure out the pinout and design a NVME carrier board. There are 6 pieces available for 400 TWD ~14 USD each. The whole idea here would be to build a Frankenstein setup - simply to just try it; I know it’s silly to take where 6x NVMe drives would go and turn it into 12x. I’d use some m.2 to PCIe 4x adapters, install these PCIe switches, and then run to the custom daughter boards.
Here’s an example of a MiniHDMI used on a similar device.
