Will this cable HD Mini SAS (SFF-8643) - SlimSAS (SFF-8654), SAS work on this backplane if you had a card like this Linkreal 8 Port U.2 to PCIe x16 SFF-8643 NVMe SSD Adapter with Heatsink-LRNV9349-8I/LRNV9348-8I
The backplane has Oculink x4 (SFF-8611) connectors, not slimsas. So no.Will this cable HD Mini SAS (SFF-8643) - SlimSAS (SFF-8654), SAS work on this backplane if you had a card like this Linkreal 8 Port U.2 to PCIe x16 SFF-8643 NVMe SSD Adapter with Heatsink-LRNV9349-8I/LRNV9348-8I
This would be a better choice:My bad, I should have read the data sheet:
"The NVMe ports, designated CN1 through CN24, are used to connect the OCuLink cables."
Do you have any better suggestions?24 cables - what a cable clutter..
I'm curious if broadcom works on a "tri mode" expander backplane...24 cables - what a cable clutter..
Sorry, was out a bit. It's serverschmiede.comWhich famous orange site are you referring to?
From reading/watching a lot of L1Techs content, seems like cables and adaptors with pcie gen 4 are quite finicky.pci gen 4.0 works on the N4 etc backplanes, which are older than this, so it should work
but yes ts, pleas try!
What card/HBA did you plan to use?From reading/watching a lot of L1Techs content, seems like cables and adaptors with pcie gen 4 are quite finicky.
Sounds like you gotten other NVME backplanes with the OCuLink connector on the backplane to work at Gen 4 speeds - which cables worked? My plan was to order these SM cables….

According to FAQ Entry | Online Support | Support - Super Micro Computer, Inc. the main difference is in hybrid drive support. I wonder if BPN-NVME3-216N-S4 can sustain NVMe4 drive speeds.I am thinking about this for some weeks since I stumbled upon a CSE-216BE16-R920UB "new open box" really cheap.
I have a few questions:
I would really appreciate any info about the parts found in original AS-2114S-WN24RT! Other cables like I2C etc. could be helpful as well. Unfortunately the public documentation of these systems is much worse than for the Ultra/Hyper systems using the BPN-NVME4-216N-S4
- Backplane: You always talked about the BPN-NVME3-216N-S4 in this thread. I would prefer the BPN-NVME4-216N-S4 found in AS-2114S-WN24RT. Any reason to stick to the older one except for price?
- Power connectors: My case comes with an old PDB-PT829-S8824 and does not have the power connectors needed. Unfortunately the website for the AS-2114S-WN24RT seems to have many copy/paste errors. First of all the pictures are all from the older AS-2113S-WN24RT. Second it lists the same PDB but the backplanes have different connectors 4x 4pin vs 2x 8pin. Those 8pins are smaller than EPS but I only found cables to connect the power connectors on Supermicro Ultra/Hyper-style boards to this backplane.
- Next thing is the compatibility of the PDB with the case. There is at least another style like the PDB-PT825-8824 found in 825/826 cases and as long as I don't know if the original PDB of AS-2114S-WN24RT will fit my case, I can't start shopping for parts because in the end this might break the built and I would resort to mimicking the older AS-2113S-WN24RT (PDB fits my case, cheaper mainboards in used market, cheaper retimer cards but not gen4)
I guess it will be more of an compatibility thing. Some drives probably won't link at gen4 at all with BPN-NVME3-216N-S4 and SlimSASx8 -> OCuLink cables. I want a system that works with a wild mix of drives so I am eager to avoid compatibility issues as long as its easily possible.I wonder if BPN-NVME3-216N-S4 can sustain NVMe4 drive speeds.
The backplanes have completely different connectors for data as well als power, so I guess the answer from Supermicro is simplified with a user in mind who wants to know what he can get on the highest level.According to FAQ Entry | Online Support | Support - Super Micro Computer, Inc. the main difference is in hybrid drive support.
