No worries. I will get on the installation later. At this point I'm pretty sure that it is not related to a defective cable, as I by now have three cables from different vendors laying around that I tested with. All from different manufacturers, all forwarding. A reverse cable would not make and sense, right? Grasping for straws here 🙂

Yes, the original cable works, but that cable only has two usable SATA plugs, which is not enough for my setup. The board should supply four through the SFF port and with three directly onboard seven in total.

Hi, as Unraid is not setup yet that proves to be difficult at the moment. However the drives should already show up in the BIOS. When using the original Fujitsu cable they do, so I don't expect any changes when installing Unraid, right?

Hey guys, new to Unraid and the forum, having a problem with a new build. I was able the get my hands on a Fujitsu W570 workstation, that uses the D3517-A13 as a proprietary mainboard. It's utilising a C236 chipset and comes with three SATA-Ports and one mini SAS HD (SFF-8643) port, that should also give me access to four more SATA drives. This is where I'm having trouble. I puchased this cable of Amazon: https://www.amazon.de/dp/B09875RVC3?ref=ppx_yo2ov_dt_b_product_details&th=1 To my suprise the drives connected to this via the SFF-8643 port don't show up in the BIOS. If I connect them to the regular SATA ports of the board they work fine. The workstation came with a proprietary cable from Fujitsu: https://www.immel.de/en/cable-sata-power-38049449 If I connect the drives using this cable they work fine as well, but I would have only two usable ports. I verified that this is not a power issue, as the drives work on the SATA ports the mainboard provides, regardless of the power source (cable from the link above, or the one that powers the two 3,5" HDD bays and is connected to the port bottom right on the mainboard). I ordered a SFF-8643 to SATA cable from a different manufacturer to no avail. I validated, that the cables are forwarding cables. I checked the manual of the board, or atleast everything that Fujitsu provides, but saw nothing that would indicate that this shouldn't work: I checked the BIOS. It's set to AHCI. I played around with the settings a bit but was not able to achieve anything. There is no dedicated BIOS to a SAS controller, so I suspect, that the SFF-port on the board is indeed just providing SATA functionality, as no SAS drives are listed as compatible in the datasheet of the machine: https://sp.ts.fujitsu.com/dmsp/Publications/public/ds-CELSIUS-W570.pdf I'm not sure as to why this is not working and I'm out of ideas at the moment. Maybe someone here has run into a similar issue or there is something that I overlooked? Thank you!
