Running Head: snap A FAULT valuation account SYSTEM RAID A Fault Tolerance dodging Calvin A. Black RAID originally was an acronym for Redundant Arrays of Inexpensive Disks. sometimes the letter I stands for independent. The two names ar hold interchangeably. The solution provides many takes of fault tolerance for disk host resources. The RAID technology is a familiar mainstay in server management. “The strategy was originally the shadowing or retroflex 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 without delay specialized and costly. RAID is in the preservation of selective information and information. RAID is a informationbase fault tolerant strategy. To an operating written text the RAID technology is a ace logical testy drive. A disk stripping technique is used in this technology. The go involves partitioning each drives storage space into units. “The units grip from a sector to several megabytes.”(para.3) The strips of information are interleavedand place in order. The stripping of a disk increases mathematical performance 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 performance standards which equates to change magnitude 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 with(predicate) the implementation of redundancy. Morereliable subsystem storage is achieved. This process is superior to a sing! le disk, which equates to less of a incident of failure resulting from a computer hardware fault.
