Running Head: snap A FAULT valuation account SYSTEM RAID A Fault Tolerance strategy Calvin A. Black RAID originally was an acronym for Redundant Arrays of Inexpensive Disks. sometimes the letter I stands for independent. The two names atomic number 18 use interchangeably. The solution provides many levels of fault tolerance for disk server resources. The RAID technology is a familiar mainstay in server management. “The strategy was originally the shadowing or written matter 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 promptly specialized and costly. RAID is in the preservation of entropy and information. RAID is a infobase fault tolerant strategy. To an operating musical arrangement the RAID technology is a wiz logical prepare drive. A disk stripping technique is used in this technology. The go involves partitio ning each drives storage space into units. “The units prehend from a sector to several megabytes.”(para.3) The strips of information are interleavedand orchestrate in order. The stripping of a disk increases mathematical procedure 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 location were five dollar bill levels of RAID. There are now nine levels plus a non-redundant array, RAI D 0. Each level has increasing advantages an! d performance standards which equates to change magnitude cost as the levels increase. Each level provides a higher(prenominal) degree of performance that the preceding, unremarkably 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 computer hardware fault.
