The setup worked fine with Windows 2012 R2, which saw both card and disks and was able to create a raid0-array for testing.

I apologize for any confusion. For linux-servers I usually install CentOS on a separate system disk, with user-data on another separate disk or as in this case on the other ten drives which are to form a single raid-array. -- //Sorin
