  • Page 11: General Raid Concepts

    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.

  • Page 12: Raid Level 0

    Introduction RAID Levels RAID Level 0 : “ Disk Striping “ High I/O Performance Improved I/O performance is the major reason of using RAID level 0. No protection is provided against data loss due to member disk failures. 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 system operation.

  • Page 13: Raid Level 1

    Introduction RAID Level 1: “Disk Mirroring” High Data reliability RAID level 1 provides both very high data reliability and continued data availability in the event of a failure of an array member. When a RAID level 1 member disk fails, array management software simply directs all application requests to the surviving member.

  • Page 14: Raid Level 0

    Introduction RAID Level 3 : “ Parallel Transfer Disks with Parity “ High Data Reliability & Highest Transfer Capacity 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 I/O with a high data transfer rate.

  • Page 15: Raid Level 1

    Introduction RAID Level 5 : “ Independent Access Array with Rotating Parity “ High Data Reliability & Transfer Capacity 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.

  • Page 16: Raid Level 5

    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...
