Running Head: snap A FAULT leeway 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 are utilise interchangeably. The solution provides many levels of fault tolerance for disk waiter resources. The RAID technology is a familiar mainstay in server management. “The strategy was originally the shadowing or copy 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 now specialized and costly. RAID is in the preservation of data and information. RAID is a database fault tolerant strategy.
To an operating transcription the RAID technology is a single logical rough drive. A disk stripping technique is used in this technology. The go involves partitioning each drives storage space into units. “The units clutches from a sector to several megabytes.”(para.3)
The strips of information are interleavedand address in order. The stripping of a disk increases mathematical process 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 there 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 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.
