So, I'm trying to configure this expander card into my server.
I have an Intel Server Board S2600WT in a R2312WTTYS case, which means I have a backplane in the front with 12 slots, and another backplane in the back holding 2 disks.
Front backplane has 10 disks: slots 0 and 1 holding a SSD, and slots 2-9 holding a SATA disk. These are connected to the expander as instructed here on page 48 in the PDF, connecting front backplane to first 3 slots in the expander card, and connecting last 2 ports in the expander card to the motherboard's SATA ports 0-3 (motherboard has 2 mini SAS HD ports named the same).
Back backplane holds 2 SSD. These are connected to SATA ports 4 and 5 respectively.
Problem is, system is not recognizing the expander, nor the disks connected to it.
I tried with both RAID controllers in the BIOS: INTEL ESRT2 (LSI+), and INTEL RSTe; but none of them seems to find the card.
I tried connecting only one port of the expander to the motherboard. Also tried disconnecting SATA drives at ports 4 and 5. And also tried changing the order of the connections in the expander.
I have no idea how this should look, or how to go any further. Am I missing something? or is something wrong with my expander card?
