preliminary draft ? subject to change without notice 2 an introduction to raid ra id - redundant a rray of independent disks raid technology manages multiple disk drives to enhance i/o performance and provide redundancy in order to w i thstand the failure of any individual member, w i thout t he loss of data. t here are many different methods of implementation for raid, w i th each having advantages and disadvantages. raid levels or set ty pes are given a numerical des ignator that defines its implementation such as raid 0 or raid 1. sat araid5 pr ovides support for three raid group ty pes: striped (raid 0), mirrored (raid 1), and raid 10 mirrored/striped. other raid ty pes are not supported by sat araid5 softw are and thus are not discussed. 2.1 disk striping (raid 0) striping is a performance-oriented, non-r edundant data mapping technique. w h ile stripi ng is discussed as a raid group ty pe, it is does not provide any fault tolerance. with modern sat a and at a bus mastering technology , multiple i/o operations can be performed in parallel, enhancing data throughput. striping array s use multiple disks to form a larger virtual disk. t he figu re below illustrates a three-disk stripe set. stripe one is w r itten to disk one, stripe tw o to disk tw o, and so forth. raid 0 sets can be comprised of tw o, three, or four drives. st r i pe 2 sataraid user?s manual copy right ? 2003 silicon image inc. st r i pe 5 st r i pe 8 s t ri pe11 str i pe 0 str i pe 6 s t ri pe9 str i pe 1 s t ri pe7 str i pe 1 0 str i pe 3 str i pe 4 2.2 disk mirroring (raid 1) disk mirroring creates an identical tw in for a selected disk by having the data simultaneously w r itten to tw o disks. t h is redundancy provides instantaneous prot ection from a single disk failure. if a read fa ilure occurs on one drive, the sy stem read s the data from the other drive. raid 1 se ts are comprised of tw o drives. a third dr ive can be allocated as a spare in case one of the drives in the set fails. bl oc k 0 bl oc k 1 bl oc k 2 bl oc k 3 bl oc k 0 bl oc k 1 bl oc k 2 bl oc k 3 2.3 disk mirroring and striping (raid 10) raid 10 combines the features of both raid 0 and raid 1. performance is prov ided through the use of striping (raid 0), w h ile adding the fault tolerance of mirrori ng (raid 1). t he implementation of raid 10 requires four drives. t he drives are assigned as tw o sets of striped pairs. 7 free datasheet http:///
preliminary draft ? subject to change w i thout notice t he data is w r itten to raid group a, w h ich is striped (raid 0). t h is allow s maximum speed. t he data is then mirrored to another raid 0 striped set, w h ich is set b in the figure abov e. t h is provides data redundanc y (raid 1), and thus increased data security . under certain circumstances, a raid 10 set can sustain multiple simultaneous drive failures. 2.4 parity raid (raid 5) parity or raid 5 adds fault tolerance to disk striping by incl uding parity information w i th the dat a. parity raid dedicates the equivalent of one disk for storing parity stripes. t he data and parity information is arranged on the disk array so that parity is w r itten to different disks. t here are at least 3 members to a parity raid set. t he follow i ng ex ample illustrates how the parity is rotated from disk to disk. parity raid uses less capacity for protection and is the pr eferred method to reduce the co st per megaby te for larger installations. mirroring requires 100% increase in capacity to protect the data w hereas the abov e example only requires a 50% increase. t he required capacit y decreases as the number of disks in the group increases. 2.5 jbod (just bunch of disks) t he jbod is a virtual disk that can eit her be an entire disk drive or a segment of a single disk drive. f o r home edition, jbod function only supports one disk. copy right ? 2003 silicon image inc. sat araid5 user?s manual 8 free datasheet http:///
