Hi Guys,

I need some advice.

I have a backplane in a server case with sata connection and SGPIO connection.

Currently this has a cable SFF8087 -> sata and SPGIO connection cable.
For example: Genuine Amphenol SFF8087 Reverse Right Angled to 4xSATA Cable 93cm w/ SGPIO | eBay


This is good, if I have SFF8087 SAS connector integrated to my motherboard.

But what can I do, when I will have oculink connectior on the motherboard?

I have found oculink -> 4xsata cable, but I didnt found this type of cable equipped with SGPIO connection.

Is it exists, or it is a dream?

I do not want to use the PCIE slot to a SAS / SATA controller, i prefer oculink to sata, and I would like to see hdd leds blinking of hdd's, too.

Thanks

Is OcuLink even compatible with Sata?
I always associated it with NVMe...
8643 can carry both nvme and SAS, but Oculink?

Yep, you can get some Supermicro boards that support 4 x Sata breakout or 4x PCIe on OCuLink ports. X11SDV boards I know do.

Yes I found that one too, but none with sideband, not even the 8643 ones...

Maybe modern controllers can take over the functionality and take to the backplane via the drive interface? No idea to be honest, just guessing ;)

My problem is, I have case with backpane 4 sata and sgpio connector, I have minisas cable with sgpio, but I want to buy mini itx motherboard and i would like to see operation of disk to be visible, so I need sgpio cabling, too. :)

I have no decision yet about motherboard, so it is going to be interesting.

What specifically are u using the sgpio for?
I thought it was for functions like locating disks or updating firmware on the backplane... but never really looked into it tbh
