Abstract

In order to improve the performance of I/O and reliability, 1980's disk arrays were introduced, in which we have used multiple disks in parallel. Today, it is used by most of the companies as a product. In this paper, we provide the complete overview of disk arrays and propose a framework for which we can organize current and future work of RAID (Redundant Arrays of Inexpensive Disks). There are two architectural techniques used in disk array, to improve the performance striping across multiple disks, and redundancy is used to improve reliability. This paper describes seven disk array architecture called RAID with levels 0-6 and also equates the cost, performance and their reliability. At last we discuss the advanced topic, such as how to improve performance by purifying the RAID levels and maintain the consistency by designing algorithm.

Keywords

RAID, Array of disks, RAID levels, Stripping, Mirroring.
