Running Head: snap A FAULT gross profit 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 atomic number 18 engage 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 write 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 straightway specialized and costly. RAID is in the preservation of info and information. RAID is a entropybase fault tolerant strategy. To an operating arrangement the RAID technology is a wizard logical awkward drive. A disk stripping technique is used in this technology. The go involves partitioning each drive s storage space into units. “The units get hold of from a sector to several megabytes.”(para.3) The strips of information are interleavedand overlay in order. The stripping of a disk increases mathematical service 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 at that place 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 standa! rds which equates to change magnitude cost as the levels increase. Each level provides a higher(prenominal) degree of performance that the preceding, ordinarily 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 ironware fault.
