C HA PTER ® ABOUT NVIDIA MEDIASHIELD™ 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 resi

CHAPTER 1 About NVIDIA® MediaShield™ RAID Arrays This section describes the following types of RAID arrays that MediaShield supports: • RAID 0 RAID 0 defines a disk striping scheme that improves the disk read and write times for many applications. • RAID 1 RAID 1 defines techniques for mirroring data. • RAID 0+1 RAID 0+1 combines the techniques used in RAID 0 and RAID 1 arrays. 1 • RAID 5 RAID 5 provides fault tolerance and better utilization of disk capacity. • JBOD JBOD provides a method

CHAPTER 1 About NVIDIA® MediaShield™ RAID 0 How RAID 0 Works In a RAID 0 array, the controller ʺstripes ʺ data across multiple drives in the RAID subsystem. RAID 0 breaks up a large file into smaller blocks and then performs disk reads and writes across multiple drives in parallel. The size of each block is determined by the stripe size parameter, which you set during the creation of the RAID 0 set. Performance of applications running with a RAID 0 can vary greatly depending on the stripe s

CHAPTER 1 About NVIDIA® MediaShield™ RAID 1 How RAID 1 Works In a RAID 1 array, every read and write is carried out in parallel across two disk drives. The mirrored—or backup—copy of the data can reside on the same disk or on a second redundant drive in the array. RAID 1 provides a hot-standby copy of data if the active volume or drive is corrupted or becomes unavailable due to a hardware failure. RAID 1 techniques can be applied for high-availability solutions, or as a form of automatic bac

CHAPTER 1 About NVIDIA® MediaShield™ RAID 0+1 How RAID 0+1 Works RAID 0 drives can be mirrored using RAID 1 techniques, resulting in a RAID 0+1 solution for improved performance plus resiliency. Figure 1.3 RAID 0+1 Array Diagram The controller combines the performance of data striping (RAID 0) and the fault tolerance of disk mirroring (RAID 1). Data is striped across multiple drives and duplicated on another set of drives. Summary of Features and Benefits • Benefits: Optimizes for both fault

CHAPTER 1 About NVIDIA® MediaShield™ RAID 5 How RAID 5 Works RAID 5 stripes both data and parity information across three or more drives. It writes data and parity blocks across all the drives in the array. Fault tolerance is maintained by ensuring that the parity information for any given block of data is placed on a different drive from those used to store the data itself. Figure 1.4 RAID 5 Array Diagram Summary of Features and Benefits • Benefits: An ideal combination of good performance,

CHAPTER 1 About NVIDIA® MediaShield™ JBOD How JBOD Works JBOD stands for “Just a Bunch of Disks”. Each drive is accessed as if it were on a standard SCSI host bus adapter. This is useful when a single drive configuration is needed, but it offers no speed improvement or fault tolerance. Figure 1.5 JBOD Array Diagram Summary of Features and Benefits • Benefits: JBOD provides the ability to combine odd size drives using all of the capacity of the drives. • Drawbacks: No additional fault toleran

CHAPTER 1 About NVIDIA® MediaShield™ having to go through multiple steps. The migrating feature gives the user an upgradeable option to manage storage easily. • Hot Plug Array A nice flexibility feature is the ability to move MediaShield RAID arrays from one nForce system to another. Since most nForce systems support SATA hot plug capability, you can add/remove a RAID array even while the system is running. This is done using the Hot Plug Array wizard.
