When the controller creates a RAID 0+1 set, it first sorts the drives by channel
number and SCSI ID. Then it stripes the data across every other drive and
forms a mirrored pair with the first two drives, another mirrored pair with the
second two drives, and so on. Table 24 lists how the controller uses the drives
in a RAID 0+1 set.
