Chapter 1: " Introduction " This chapter will introduce you to your new Disk Arrays features and provide information on general RAID concept.
Introduction This section provides an overview of the features. For more detailed information, please refer fo the technical specifications appendix at the end of this manual . Arena includes the following features ; Easy Operation As everyone knows, conventional Disk Arrays are designed for experienced computer specialists.
Introduction Solid reliability « Automatic failed disk dive detection. . Auto rebuild : when a replacement disk installed (or by using hot spare disk ), Arena provides automatic data rebuild without any commands of functions keyed In. ( Transparent to Host | Efficient maintenance + An LCD status panel displays a comprehensive readout of the operating status, and the HDD LED indicators on each HDD tray display the individual HDD status.
Introduction General RAID Concepts Connect Installation of the disk may requires an understanding of RAID technology and the concepts described in this section. Definition RAID Is an acronym of Redundant Ana 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 Disk Disk Disk Disk Disks Disk Physical ® Improved VO performance is the major reason for using RAID level 0. @ No profession is provided against data loss due to member disk failures.
Introduction @® RAID level 0 nays are not particularly suitable for + Applications which make sequential requests for small amount of data. These applications will spend most of their [10 time waiting for disks to spin, whether or not they use striped amass as storage media. * Applications which make synchronous random requests for small amounts of data.
introduction RAID Level 1 : " Disk Mirroring " High Data reliability Physical RAID level 1 provides both very high data reliability and confined 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 10 the surviving member.
Introduction RAID Level 3 : " Parallel Transfer Disks with Parity High Data Reliability & Highest Transfer Capacity Disk Disk Disk Disk Disk 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 JO 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. RAID level 3 In not well suited for transaction processing or other I/O request-intensive applications.
Introduction RAID Level 5 : " Independent Access Array with Rotating Parity High Data Reliability & Transfer Capacity Disk Disk Disk Disk Disks Disk Physical P : Parity When RAD Level & technology is combined with coke memory to improve fs write performance, the result can be used In any applications where general purpose disks would be suitable. For read only or read mostly application VO loads, RAID Level 5 Performance should approximate that of a RAID Level 0 antsy.
Introduction ® RAID level 5 nays have unique performance characteristics The data con be recalculated or regenerated, using party, when any drive in the may fails. « When the galled drive is replaced, ether 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 galled dive onto the new rive.
