RAID Software User’s Guide
• Configurations of one or two IM or IME volumes on the same Intel
®
IT/IR RAID
Controller. IM volumes have two mirrored disks; IME volumes have three to ten
mirrored disks. Two volumes can have up to a total of 12 disks.
Note: This feature requires IR RAID firmware v1.20.00 or above to be installed.
• One or two global hot-spare disks per controller, to automatically replace failed disks in
IM/IME volumes. The hot-spare drives are in addition to the 12-disk maximum for two
volumes per Intel
®
IT/IR RAID Controller.
Note: Support for two hot-spare disks requires IR RAID firmware v1.20.00 or above.
• Mirrored volumes run in optimal mode or in degraded mode (if one mirrored disk fails).
• Hot-swap capability.
• Presents a single virtual drive to the OS for each IM/IME volume.
• Supports both SAS and SATA disks. The two types of disks cannot be combined in the
same volume. However, a Intel
®
IT/IR RAID Controller can support one volume with
SATA disks and a second volume with SAS disks.
• Fusion-MPT* architecture.
• Easy-to-use BIOS-based configuration utility.
• Error notification: The drivers update an OS-specific event log.
• LED status 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 the host continues to process
inputs/outputs (I/Os).
• Background media verification ensures that data on IM/IME volumes is always
accessible.

RAID BIOS Console 2 Configuration Utility for
Intelligent RAID
The Intel
®
RAID BIOS Console 2 configuration utility provides full-featured, GUI-based
configuration and management of RAID arrays. The Intel
®
RAID BIOS Console 2 utility
resides in the controller firmware and is independent of the operating system. The Intel
®
RAID BIOS Console 2 configuration utility lets you:
• Select an Intel
®
RAID controller
• Choose a configuration method for physical arrays, disk groups, and virtual drives
• Create drive arrays
• Define virtual drives
• Initialize virtual drives
• Access controllers, virtual drives, and physical arrays to display their properties
