    Question for the group...anyone know of a way to use an adaptec U160
    controller to connect the NAS server to another system so the second system
    can write to the raid container thru the U160?

        -rw->(PCI U160)<-->(U160 CABLE)<-->(SERVER)

    I am almost a bit curious why you didn't go with a Microsoft based
    solution in a situation like this, where you are needing to provide
    SMB based file sharing to obviously Windows client desktops.

    Another solution would be to setup a dedicated NAS of some sort. But I
    suppose it's too late for all of that.
