    With the new 800Mhz FSB Xeon's around the corner (well released, I just
    can't get one yet) I'm hoping I can take advantage of the faster hardware...
    I wrote an email to the people mentioned in the iir man page asking for
    clarity on the supported hardware etc, and didn't get a response... The fact
    that you are seeing change is a good thing... SOMEONE is doing something to
    the code - does anyone know who?

    If I get the new gear, I could set up remote console access so that the
    appropriate person could work on it... that level of C is well beyond me,
    but I figure providing access to the gear would help - does anyone know who
    to communicate with?

    The new boards SE7520JR2 don't support / aren't certified / recommended with
    some of the older storage controllers... I could use it with an adaptec -
    but that seems like a crime when there such neat offerings from Intel with
    such impressive specs.

    The new board supports "HOSTRAID" - not sure what that is, but neither is
    anyone at intel support ;-)

    I've seen references to adaptec, but the controllers on board are LSI
    Logic - not adaptec.

    The compatibility matrix:
    http://www.intel.com/design/servers/buildingblocks/boardsmatrix.htm

    Seems to indicate SRCS16, SCRZCRX, and SRCU42X are compatible options...

    SRCS16 is a SATA raid controller....
    SRCU42X seems like it's over the top for my needs... the most expensive
    one...

    SRCZCRX seems most appropriate for me. My goal - after discussion and
    feedback from the list is to run RAID mirror sets of 10K scsi drives... so
    hardware xor speed isn't important - it's quite a basic setup.

    If I use the old generation boards, the SCRZCR will be appropriate - but it
    doesn't work - except on the beta? So the hope of seeing the SCRZCR work is
    slim eh?

    So - how do I get to the people who can tell me if it's supported? Or so I
    can get them the resources to debug?

    Or should I just stick to a ADAPTEC 2120S or a LSI 3201064KIT MEGARAID
    U320-1?

    Thanks again!
