   • Redundant Array of Independent Disks (RAID) | Set 2

     Redundant Array of Independent Disks (RAID) is a set of several physical disk drives that Operating System see as a single logical unit. It played a significant role in narrowing the gap between increasingly fast processors and slow disk drives.

     The basic principle behind RAID is that several smaller-capacity disk drives are better in performance than some large-capacity disk drives because through distributing the data among several smaller disks, the system can access data from them faster, resulting in improved I/O performance and improved data recovery in case of disk failure.

     A typical disk array configuration consists of small disk drives connected to a controller housing the software and coordinating the transfer of data in the disks to a large capacity disk connected to I/O subsystem. Note that this whole configuration is viewed as a single large-capacity disk by the OS.

     • Data is divided into segments called strips, which are distributed across the disks in the array.
     • A set of consecutive strips across the disks is called a stripe.

   • RAID (Redundant Arrays of Independent Disks)

     RAID is a technique that makes use of a combination of multiple disks instead of using a single disk for increased performance, data redundancy, or both. The term was coined by David Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987. 

     Why Data Redundancy?

     Data redundancy, although taking up extra space, adds to disk reliability. This means, that in case of disk failure, if the same data is also backed up onto another disk, we can retrieve the data and go on with the operation. On the other hand, if the data is spread across multiple disks without the RAID technique, the loss of a single disk can affect the entire data.

This means, in case of disk failure, if the same data is also backed up onto another disk, we can retrieve the data and go on with the operation. On the other hand, if the data is spread across just multiple disks without the RAID technique, the loss of a single disk can affect the entire data.

    RAID allows information to be spread across several disks. RAID uses techniques such as disk striping (RAID Level 0), disk mirroring (RAID Level 1), and disk striping with parity (RAID Level 5) to achieve redundancy, lower latency, increased bandwidth, and maximized ability to recover from hard disk crashes.

    The term RAID was adopted from the 1988 SIGMOD paper “A Case for Redundant Arrays of Inexpensive Disks (RAID).” In the paper, RAID refers to a group of storage schemes that divide and replicate data among multiple disks to provide better performance, cost and power consumption rate with reasonable availability comparing with conventional Single Large Expensive Disk (SLED) used for Mainframe.
