Hi,
I wanted to upgrade my storage server with more disks, unfortunately the Supermicro (while it is an excellent board itself) only provides SATA-type ports (although they are SAS2 ports actually) for the LSI controller.
Now I read (also on this board I think) that the Intel RES2SV240 (also a LSI controller in disguise) should work with that mainboard.
So my configuration is now:
Supermicro X10SL7-F
to
Intel RES2SV240 Expander (Port 1 and 2 to mainboard, Port 3 to 6 to the backplane on the chassis)
to
an Intertech IPC-4U-4316L chassis (four SAS backplanes)
The Supermicro is connected to the Intel SAS Expander via a Mini SAS SFF80887 to 4x SATA "OCR" (reverse breakout?) cable - which I thought should be the correct one?
The chassis is connected using the SAS cables delivered with the Intel SAS Expander (SAS to SAS) to the Expander.
The LSI controller on the Supermicro board is flashed to IT mode (if it matters for that case) as it was recommended for a napp-it (ZFS) server.
When I enter the LSI configuration (Ctrl + C) during boot, and check SAS topology ... there are NO devices to display!
Also when I directly connect a SAS backplane from the chassis to the mainboard using the OCR cables, I also don't get any drive info. (drives worked flawlessly via normal SATA cables direct to drives)
Unfortunately the Intel SAS Expander doesn't even have a LED so I know it is actually working!? (and I don't know if it should work using OCR cables directly to SAS backplane on chassis)
The Expander is powered by the 4 pin molex connector (not installed in a PCIe slot).
Is anyone proficient with SAS connectivity to see if I used wrong cables or there is another problem in my setup?
