Use this option to create an integrated mirror enhanced array of three to eight
disks, including up to two optional hot spares. All data on the array disks will
be deleted.

Use this option to create an integrated striping array of two to eight disks. All
data on the array disks will be deleted.
v
Hard disk drive capacities affect how you create arrays. The drives in an array
can have different capacities, but the RAID controller treats them as if they all
have the capacity of the smallest hard disk drive.
v If you use an integrated SAS/SATA controller with RAID capabilities to configure
a RAID 1 (mirrored) array after you have installed the operating system, you will
lose access to any data or applications that were previously stored on the
secondary drive of the mirrored pair.
v
If you install a different type of RAID controller, see the documentation that
comes with the controller for information about viewing and changing settings for
attached devices.

mirrored pair.
