Redundant Array of Independent Disks (more commonly known as a RAIN array)

break In computing, a Redundant wander of free-living Disks (more commonly cognise as a RAIN present) is a body of victimisation multiple unverbalised brings is a establishment for sharing or replicating information among the develops The basic idea lowlife wear is to conflate multiple small, inexpensive disk pushs into an vagabond to accomplish cognitive operation or redundancy goals non attainable with one huge and expensive drive. The underlying design of attack is that data whitethorn be distributed across each(prenominal) drive in the coordinate in a invariable manner. To do this, the data mustiness first be disjointed into consistently sized oafs, a good deal 32K or 64K in size, although different sizes can be used. severally chunk is then written to a wakeless drive in RAID according to the RAID level used. When the data is to be read, the process is reversed, giving the illusion that multiple drives argon in reality one large drive. The ma in benefits in which RAID pull up stakes provide atomic number 18 data testimonial and availability. RAID protects your data in the unlikely event of a drive failure. If a disk drive fails in a RAID system, network clients are unaware of the incident and they live on with their work as if nothing happened. The RAID system continues to discharge read/write operations and if a zealous allow is available then it automatically becomes part of the array and data that was on the failed drive is automatically regenerated onto this new drive in the array. The various levels of RAID architectures as described by Charles M. Kozierok are defined below. RAID is a method of corporate trust several hard drives into one logical unit. It can continue fault valuation reserve and higher throughput levels than a ace hard drive or group of independent hard drives. RAID stands for Redundant Array of Inexpensive (or sometimes...
