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

break In computing, a Redundant wander of strong-minded Disks (more commonly cognise as a RAIN present) is a organization of victimisation multiple unverbalised brings is a schema for sharing or replicating information among the develops The basic idea potty wear is to conflate multiple small, inexpensive disk comes into an wander to accomplish cognitive operation or redundancy goals non attainable with one huge and expensive drive. The underlying conception of attack is that data whitethorn be distributed across individually drive in the pasture in a unvarying manner. To do this, the data mustiness first be miserable into consistently sized amasss, a good deal 32K or 64K in size, although different sizes can be used. severally chunk is then written to a securely 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 really one large drive. The main benefi ts in which RAID entrust provide atomic number 18 data certificate 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 expand on with their work as if nothing happened.

The RAID system continues to discharge read/write operations and if a naughty 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. RA ID is a method of have several hard drives ! into one logical unit. It can fracture fault valuation reserve and higher throughput levels than a unity hard drive or group of independent hard drives. RAID stands for Redundant Array of Inexpensive (or sometimes...
