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 Data Disk Array Controller Array Management Software Provides Logical to Physical Mapping 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.
Page 14
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.

Introduction RAID level 5 arrays have unique performance characteristics : The data can be recalculated or regenerated, using parity, when any drive in the array fails. When the failed drive is replaced, either automatically if the subsystem contained a hot spare drive, or by user intervention during a scheduled maintenance period, the system will be restored its full data redundancy configuration by rebuilding all of the data that had been stored on the failed drive onto the...
