Steps to configure Raid in linux

(Redundant Array of Independent Disks) A disk subsystem that is used to increase performance or provide fault tolerance or both. RAID uses two or more ordinary hard disks and a RAID disk controller. In the past, RAID has also been implemented via software only.

In the late 1980s, the term stood for “redundant array of inexpensive disks,” being compared to large, expensive disks at the time. As hard disks became cheaper, the RAID Advisory Board changed “inexpensive” to “independent.”
