Just build your own system with dual controllers. Setup each raid controller as a 0, 5 or 6 based on your needs and then use linux to create a software mirror between the two. Try to have extra drives on each controller for hot spares. Pick a chassis with dual power supplies, hot swapable would be nice. If you need redundancy for the MB you really need a second chassis. Or for a single chassis that has two mother boards, check this one out. http://www.supermicro.com/products/chassis/1U/?chs=809 We have used these in certain situations where we needed to increase the density of a rack.
