1 Introduction to the Integrated RAID Solution Overview The Intel® Integrated RAID Solution provides cost benefits for the server or workstation market that requires the extra performance, storage capacity, and redundancy of a RAID configuration. The Intel® Integrated RAID Solution includes the following RAID features: • The Integrated Mirroring solution, which provides features of RAID 1 • The Integrated Mirroring + Striping solution, which provides features of RAID 10 • The Integrated Mirroring Enhanced solution, which provides features of RAID 1 Enhanced (RAID 1E) • The Integrated Striping solution, which provides features of RAID 0 By simplifying the configuration options and by providing firmware support in its SAS-3 host adapters, Intel can offer the Integrated RAID solution at a lower cost than a hardware RAID implementation. Intel Fusion-MPT™ firmware supports Integrated Mirroring volumes, Integrated Mirroring + Striping volumes, Integrated Mirroring Enhanced volumes, and Integrated Striping volumes. You can create up to two Integrated RAID volumes on each Intel SAS3 controller. The Intel® Integrated RAID Solution supports the following Intel SAS-3 controllers and the host bus adapters based on these 12Gb SAS Controller chips: • LSISAS3008 • LSISAS3004 Intel® Integrated RAID firmware uses the same device drivers as the standard Intel Fusion-MPT-based controllers, thereby eliminating the need for complex backup software or expensive RAID hardware. To conserve system resources, the Integrated RAID firmware operates independently from the operating system. The BIOS-based configuration utility, documented in Chapter 3 and Chapter 5, makes it easy to configure mirrored and striped volumes. The Integrated RAID solution is currently available as an optional component of the Fusion-MPT architecture on Intel SAS-3 controllers. Note: In this document, the terms volume, RAID volume, array, and RAID array are used interchangeably. Volume and array both appear on the screens of the BIOS-based configuration utility. The term disk means both hard disk drive (HDD) and solid state drive (SSD), and the HDDs or SSDs can support either SAS or SATA protocol. Intel® Integrated RAID Solution User Guide 1
