I found some references in Google that seemed to indicate a "fakeraid" 
controller, one that depends on the driver to do the RAID calculations...

My fear is that in case of controller failure it will be difficult to 
find in time a controller that recognizes the particular format of the 
array, or that it will be too expensive. As an example, I recently tried 
to buy the second processor for the machine (it originally came with 
only one) and wanted more than 1500 dollars (yes!) for the P4 Xeon 3GHz CPU.

I am thankful for you for answers!
