Running Head: snap A FAULT allowance account 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 are employ interchangeably. The solution provides many 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 imitation 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 instantaneously specialized and costly. RAID is in the preservation of info and information. RAID is a selective informationbase fault tolerant strategy. To an operating organisation the RAID technology is a single(a) logical clumsy drive. A disk stripping technique is used in this technology. The go involves partiti oning each drives storage space into units. “The units time lag from a sector to several megabytes.”(para.3) The strips of information are interleavedand call in order. The stripping of a disk increases mathematical work on 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 in that respect were five dollar bill levels of RAID. There are now nine levels plus a non-redundant array, RAID 0. Eac h level has increasing advantages and perfor! mance 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 by 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 hardware fault.
