v The integrated SAS/SATA controller with RAID capabilities supports the

following features:

– Integrated Mirroring (IM) with hot-spare support (also known as RAID 1)

Use this option to create an integrated array of two disks plus up to two

optional hot spare. All data on the primary disk can be migrated.

– Integrated Mirroring Enhanced (IME) with hot-spare support (also known as

RAID 1E)

Use this option to create an integrated mirror enhanced array of three to eight

disks, including up to two optional hot spare. All data on the array disks will

be deleted.

– Integrated Striping (IS) (also known as RAID 0)

Use this option to create an integrated striping array of two to eight disks. All

data on the array disk will be deleted.

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 SAS

settings for attached devices.
