Introduction RAID Levels RAID Level 0 : * Disk Striping " High I/O Performance Disk Disk Disk Disk Disks Disk Physical @® Improved IO performance is the major reason for using RAID level 0. No protection is provided against data loss due to member disk allures. A RAID level 0 array by itself is thus an unsuitable storage medium for data that can not easily be reproduced, or for data that must be available for critical stern operation.
Introduction RAID Level 1 : " Disk Mirroring " High Data reliability Physical Optional RAID level 1 provides both very high data reliability and continued data availability In the event of a allure of an aay member, When a RAID level 1 member disk falls, ray management software simply directs all application requests to the surviving member.

Introduction RAID Level 5 : " Independent Access Array with Rotating Parity » High Data Reliability & Transfer Capacity Disk Disk Disk Disk Disk Disk Physical P : Parity When RAID Level 5 technology Is combined with cache memory to improve its write performance, the result can be used in any applications where general purpose disks would be suitable. For read only or read mostly application I/O loads, RAID Level 5 performance should approximate that of a RAID Level 0 array.
Introduction RAID Level 3 : " Parallel Transfer Disks with Parity High Data Reliability & Highest Transfer Capacity Disk 1 Disk Disk Disk Disks Disk Physical P: Parity RAID Level 3 technology use a dedicated parity disk to store redundant information about the data on several data disks. RAID Level 3 is an excellent choice for applications which require single stream FO with a high data transfer rate.
Introduction @ RAID level 0 arrays are not particular 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 fo spin, whether or not they use striped arrays as storage media.
Introduction General RAID Concepts Correct installation of the disk ray 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 This section provides an overview of the features. For more detailed information, please refer to the technical specifications appendix at the end of this manual .
