IM/IME Description 2-3

• Fusion-MPT architecture.

• Easy-to-use BIOS-based conﬁguration utility.

• Error notiﬁcation: the drivers update an OS-speciﬁc event log.

• SES status LED support.

• Write journaling, which allows automatic synchronization of

potentially inconsistent data after unexpected power-down situations.

• Metadata used to store volume conﬁguration on mirrored disks.

• Automatic background resynchronization while host I/Os continue.

• Background media veriﬁcation ensures that data on IM/IME volumes

is always accessible.

2.3 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.
