Sorry, I completely missed your question when you originally asked it.I think I did not ask question clearly.
I know that minisas headers in front of motherboard next to ethernet ports are for NTB on PCIe.
I read all your posts about 3 storage ports. I would like to thank you that It was very helpful to me.
As you explained, there are three mini SAS connectors on the mid board. One for SATA ports 2-5 and others for SAS ports 0-3 and 4-7. We know that SATA ports 2-5 are working. Not sure about their bandwidth. I think it is 3Gbps.
According to manual, SAS ports 4-7 need upgrading ROM. But nothing about SAS ports 0-3. We can use them as additional 4 drives, total 10 but you reported that only SATA ports were working. My question was about SAS ports 0-3.
Drives are connected to SATA ports 2-5 at the picture loaded by Semidetach. My question was whether he tried to connect drives to SAS port 0-3, middle socket on the picture.
Unfortunately, no, I never had a chance to test the other connectors. I've since broken down all my units and just have them as bare motherboards packed away somewhere.
