3 RAID Utilities Intel® Embedded Server RAID Technology 2 BIOS Configuration Utility With support for up to six SATA drives or eight SAS/SATA drives, depending on the server board or system, the embedded RAID BIOS has the following features: • Support for interrupt 13 and Int19h. • Support for SATA CD-ROM/DVD-ROM devices, including support for booting from a CD-ROM drive. • POST (Power On Self Test) and run-time BIOS support for device insertion and removal. • Support for a migration path from Intel® Embedded Server RAID Technology 2 to Intel Integrated Server RAID hardware. • Automatic resume of rebuilding, check consistency, and initialization. • Global hot spare support based on the virtual drive size. • Support for RAID levels 0, 1, 5, and 10. • Support for auto rebuild. • Support for different capacity disks in the same array. • Support for up to eight physical drives and eight virtual drives. • Stripe size of 64 KB only. • Support for disk coercion with options of None, 128 MB, or 1 GB. • Ability to select a virtual drive as boot device. By default, virtual drive 0 is bootable. LSI MPT* SAS BIOS Configuration Utility You can use the LSI MPT* SAS BIOS Configuration Utility to create one or two IM/IME volumes on each Intel® IT/IR RAID Controller, with one or two optional global hot-spare disks. All disks in an IM/IME volume must be connected to the same Intel® IT/IR RAID Controller. Although you can use disks of different size in IM and IME volumes, the smallest disk in the volume will determine the logical size of all disks in the volume. In other words, the excess space of the larger member disk(s) will not be used. For example, if you create an IME volume with two 100 GB disks and two 120 GB disks, only 100 GB of the larger disks will be used for the volume.
