    Hi,
    no one seem to have answered this (at least not to the list). Therefore I
    thought that I at least could tell you that I set up a PE750 for a client
    some months ago. The server uses a CERC SATA RAID 2, and is working very well
    (fast & stable). I tested things like hotplugging and booting of a
    stripe and it worked as expected.

    The server is using 4.10 (5.2.1 didn't work with the card, 5.3 (very!)probably
    does). I really wouldn't run 5.x for production use anyway.

    I would persume that the aac driver would work for a 6 channel card as well,
    as the channels are abstracted away from the OS point-of-view.
