Introduction General RAID Concepts Connect 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 Aay 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 TRAD Levels | RAID Level 0 : * Disk Striping * High I/O Performance mE — Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk® Physical @ Improved JO performance is the major reason for using RAID level 0. ® No protection is provided against data loss due to member disk failures. A RAID level 0 array by self is thus an unsuitable storage medium for data that can not easily be reproduced, of tor data that must be available for critical system operation.
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 OQ time waiting for disks 10 spin, whether or not they use striped arrays as storage medic. + Applications which make synchronous random requests for small amounts of data.
Introduction RAID Level 1 : " Disk Mirroring * High Data Reliability Disk 1 Disk j Disk 3 Disk Disk § Fiona Physical RAID level 1 provides both very high dots reliability and continued data availability in the event of a failure of an array member, When a RAID lever | member disk falls, any management software simply directs all application requests fo the surviving member.
Introduction RAID Level 3 : " parallel Transfer Disks with Parity High Data Reliability & Highest Transfer Capacity = C= 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 1/0 with a high data transfer rate.
Introduction ® The distinctive performance characteristics of RAID level 3: . RAID Level 3 provides excellent performance for data transfer-intensive applications. .
Introduction RAID Level 5: " Independent Access Array with Rotating Parity High Data Reliability & Transfer Capacity Disk 1 Disk? Disk Disk Disk§ Disk Physical P: Parity When RAID Level 5 technology is combined with cache memory to improve its write performance, the resell can be used in any applications where general purpose disks would be suitable. For read only or read mostly application JO loads, RAID Level & performance should approximate that of a RAID Level 0 array.
Introduction @ RAID level 5 arrays have unique performance characteristics : « The data can be recalculated of 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 ifs full data redundancy configuration by rebuilding all of the data that had been stored on the failed dive onto the new drive.

“Supported RAID Levels | Based on the needs of a Disk Ara's capacity, data availability, and overall performance, you can select a proper RAID lever for your Disk Array. The supported RAID levels are shown in below : introduction RAID Level Function Description Drives required Min, Max. "Disk Striping" , block striping is used, which yields higher performance than with the individual disk drives. * There is no redundant function.
