IM/IME Description
The LSI Integrated RAID solution supports one or two IM/IME volumes
on each LSI SAS controller (or one IM/IME volume and one Integrated
Striping volume). Typically, one of these volumes is the boot volume, as
shown in
Figure 2.1
. Boot support is available through the firmware of the
LSI SAS controller that supports the standard Fusion-MPT interface. The
runtime mirroring of the boot disk is transparent to the BIOS, drivers, and
operating system. Host-based status software monitors the state of the
mirrored disks and reports any error conditions.
Figure 2.1
shows an IM
implementation with a second disk as a mirror of the first (primary) disk.
