Hi! If the motherboard S2600WTTR is compatible with the controller RS3WC080? The motherboard specifications S2600WTTR not indicated support RS3WC080 board. Why?
To answer your question, only boards from the S2600CW Family will support the RS3WC080 RAID controller due to engineering specifications:
Previous generations of boards like the S2600GZ, S2600IP or S2600GL will support the controller as well.
