An IME volume can be configured with up to eight mirrored disks, or seven mirrored disks and a global hot
spare. Figure shows the logical view and physical view of an Integrated Mirroring Enhanced (IME) volume
with three mirrored disks. Each mirrored stripe is written to a disk and mirrored to an adjacent disk. This
type of configuration is also called RAID 1E.
LSI Logic provides the BIOS-based configuration utility to enable the user to create IM and IME volumes
during initial setup and to reconfigure them in response to hardware failures or changes in the environment.
