Introduction General RAID Concepts Correct installation of the disk array requires an understanding of RAID technology and the concepts described in this section. Definition RAID is an acronym of Redundant Array of Independent Disks . A RAID is a Disk Array in which part of the storage capacity is used to record redundant information about the user data stored on the remainder of the storage capacity.
Introduction RAID Levels RAID Level 0 : " Disk Striping " High I/O Performance 3 4 5 6 7 8 Data 2 9 10 11 12 1 Disk Array Controller Array Management Software Provides Logical to Physical Mapping 1 7 2 8 3 9 4 10 5 11 6 12 Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 Physical Improved I/O performance is the major reason for using RAID level 0. No protection is provided against data loss due to member disk failures.
Introduction RAID level 0 arrays are not particularly suitable for : Applications which make sequential requests for small amount of data. These applications will spend most of their I/O time waiting for disks to spin, whether or not they use striped arrays as storage media. Applications which make synchronous random requests for small amounts of data.
