Running Head: snap A FAULT allowance SYSTEM RAID A Fault Tolerance outline 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 enforce interchangeably. The solution provides many directs of fault tolerance for disk server 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 this instant specialized and costly. RAID is in the preservation of selective information and information. RAID is a infobase fault tolerant strategy. To an operating arranging the RAID technology is a champion logical cranky drive. A disk stripping technique is used in this technology. The go involves partiti oning each drives storage space into units. “The units detainment from a sector to several megabytes.”(para.3) The strips of information are interleavedand cut across in order. The stripping of a disk increases mathematical work at 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 on that point 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, 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.
