Hi Peter, I too was very undecided about using the LSI 1068e (on-board many supermicro boards) in production for this very reason. The problem is that chipset is basically unsupported by LSI and updates to it are sometimes necessary to maintain compatibility. The driver won't build sometimes on updated kernels forcing you to hold onto a particular version. Even if you could get away from that, the driver is black box and we found it to be somewhat unreliable (read: crashy). I believe even in IT mode that chipset requires a different driver (not megasr, mptsas?) and was also black box. We decided after a few update mistakes and trips to the datacenter, it wasn't worth it. I suggest instead buying a separate megaraid card (highly recommend the 92XX series) which are very well supported by the open source, in-kernel driver (megaraid_sas? megasas?). I don't believe the 1068e is a wise choice for new installations and the 4i variants run as low as $180 new. We currently run, in production, the X8DT3 with a 9240-8i card and skipped the onboard.
