CHAPTER ABOUT NVIDIA RAID NVIDIA brings Redundant Array of Independent Disks (RAID) technology-which is used by the world's leading businesses-to the common PC desktop. This technology uses multiple drives to either increase total disk space or to offer data protection. RAID techniques were first published in 1988 by a multivendor consortium-the RAID Advisory Board. RAID techniques were divided into different categories or levels. Originally, RAID levels focused on improving resiliency or data availability. As additional RAID levels were defined, one was introduced for improving performance. For all levels, RAID techniques optimize storage solutions by using multiple disks grouped together and treating them as a single storage resource. This chapter describes NVIDIA RAID in the following sections: • "System Requirements" on page 2. • "RAID Arrays" on page 3 describes the RAID levels supported by NVIDIA RAID. • "NVIDIA RAID Features" on page 9 describes additional features offered by NVIDIA RAID.
