    Dear all,

    I'm currently configuring a brand new 14 disk (x 146 GB) MSA30
    RAID-array, and now find out that there is a (new ?) opportunity for
    even more redundancy, i.e. RAID-ADG (Advanced Data Guarding).
    Does anybody have any (good or bad) experience with this technology ?
    What is the penalty ? I guess: '2 out of the 14 disks' ???

    As usually, i will summarize...
