Hi Markus, I think,if you connect more than 16 drives on back plane,X10DRH-CT will detect and show only 16 drives in BIOS. I am not sure about that. If you test this motherboard, please let me know the result.
Msg form supermicro site LSI 3108 SAS3 (12Gbps) controller; - 2GB cache; HW RAID 0, 1, 5, 6, 10, 50, 60 - Supports up to 16 devices as default, more HDD devices support is also available as an option * For special SKU, please contact your Supermicro Sales.
