Running Head: snap A FAULT gross profit SYSTEM RAID A Fault Tolerance system 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 go for interchangeably. The solution provides many directs of fault tolerance for disk host resources. The RAID technology is a familiar mainstay in server management. “The strategy was originally the shadowing or simulate 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 directly specialized and costly. RAID is in the preservation of info and information. RAID is a database fault tolerant strategy. To an operating arranging the RAID technology is a iodin logical crude drive. A disk stripping technique is used in this technology. The go involves partitioning each drives storage space into units. “The units grasp from a sector to several megabytes.”(para.3) The strips of information are interleavedand traverse in order. The stripping of a disk increases mathematical treat 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 increasing advantages and performa nce standards which equates to change magni! tude cost as the levels increase. Each level provides a higher(prenominal) degree of performance that the preceding, usually accommodating larger systems. Advantages RAID provides fault tolerance through and through the implementation of redundancy. Morereliable subsystem storage is achieved. This process is superior to a single disk, which equates to less of a incident of failure resulting from a ironware fault.
