Running Head: snap A FAULT security deposit SYSTEM RAID A Fault Tolerance scheme Calvin A. Black RAID originally was an acronym for Redundant Arrays of Inexpensive Disks. sometimes the letter I stands for independent. The two names argon use interchangeably. The solution provides many take aims of fault tolerance for disk waiter resources. The RAID technology is a familiar mainstay in server management. “The strategy was originally the shadowing or facsimile information to extra disk drives.”(Fault Tolerance, p.8) The highest level of the technology is no longer cheaper than full redundant shadowing. The RAID technology boxes are right away specialized and costly. RAID is in the preservation of entropy and information. RAID is a database fault tolerant strategy. To an operating organisation the RAID technology is a whiz logical boisterous drive. A disk stripping technique is used in this technology. The go involves partitioning each drives storage space into units. “The units detainment from a sector to several megabytes.”(para.3) The strips of information are interleavedand goal in order. The stripping of a disk increases mathematical mental process and the reliableness of the system.

“The use of multiple drives allows the resulting storage subsystems to exceed capacity, data security, and performance of the drives that make up the system…” (Storage Review, 2005, para.2) Originally thither were five dollar bill levels of RAID. There are now nine levels plus a non-redundant array, RAID 0. Each level has incre asing advantages and performance standards w! hich equates to change magnitude cost as the levels increase.

This process is superior to a single disk, which equates to less of a incident of failure resulting from a hardware fault.
