Hardware mix-n-match issues

SO I have an old Supermicro X8DT server that is working just fine.

Has 12 drives in it currently, 2 pools and a boot drive.

Wanted to change out one of the pools from 3 drives to a new 8 bay system.

This needed a new controller, and I got a new SFF backplane.

The controller is a Dell 8MW60 and shows up in lspci as follows:

04:00.0 PCI bridge: PLX Technology, Inc. PEX 8632 32-lane, 12-Port PCI Express Gen 2 (5.0 GT/s) Switch (rev bb)
05:04.0 PCI bridge: PLX Technology, Inc. PEX 8632 32-lane, 12-Port PCI Express Gen 2 (5.0 GT/s) Switch (rev bb)
05:05.0 PCI bridge: PLX Technology, Inc. PEX 8632 32-lane, 12-Port PCI Express Gen 2 (5.0 GT/s) Switch (rev bb)
05:06.0 PCI bridge: PLX Technology, Inc. PEX 8632 32-lane, 12-Port PCI Express Gen 2 (5.0 GT/s) Switch (rev bb)

The backplane is from an HP Proliant DL380. (P/N: 777279-001) It has two mini-SAS SFF-8087 jacks and a 6 pin power cable. I have the drives in trays and the leds cycle on boot.

Since the adapter is a standard PCIe card, the cabling is standard and there are no secondary signaling cables needed, I thought I could make this combo work.

But I don’t see any of the new drives showing up in the GUI, or under fdisk -l.

Does anyone have any experience with this controller?

Is there something special about this controller that I’m missing? Some driver or software package to make it work?

Couldn’t find anything specific, but some pages google spit out stated that the card is vendor locked to dell hardware

The “controller” you’re showing is an old PCIe switch. What are your drives? SATA, SAS or NVMe?
X8 hardware is probably overdue for replacement anyway…

SAS drives.

What I posted is what shows up in lspci when the controller is installed. If all that is showing is switch info, then additional SW is needed, yes?

Yes, all of the hardware is old, but it’s inexpensive - if I can get it to work.

Speed is not required in this case.

Please post the full lspci output (formatted text </>). For now we have no evidence that there’s a SAS controller in there, so it’s not going to work.
