Chapter 1: "Introduction * | This chapter will introduce you to your new Disk Array's features and provide information on general RAID concepts.
Introduction | Features l This section provides an overview of the features. For mote defiled information, please refer to the technical specifications appendix at the end of this manual Your Disk Array System includes the following features Easy Operation As everyone knows, conventional Disk Arrays are designed for experienced computer specialists.
Introduction Solid reliability + Automatic failed disk drive 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 fo Host } Efficient maintenance . Ari LCD status panel displays © comprehensive readout of the operating status, and the HDD LED indicators on each HDD tray display the individual HDD status. .
Introduction | General RAID Concepts J 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 Disk 1 Disk Disk Disk Disk Disks Physical ® Improved I/O performance is the major reason for using RAID level O. ® No protection is provided against data loss due fo member disk failures. A RAID level 0 array Dy itself is thus an unsuitable storage medium for data that can not easily be reproduced, of for 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 FO time waiting for disks to spin, whether or not they use striped arrays os storage media. + Applications which make synchronous random requests for small amounts of data.
Introduction RAID level 1 : "Disk Mirroring" --High Data Reliability Disk 3 Disk Disk Disk Physical Optional RAID level 1 provides both very high data reliability and continued data availability In the event of a failure of an array member.
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 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 5 nays have unique performance characteristics © . The data can be recalculated of regenerated, USING parity. when any drive in the array tails. . When the failed drive is replaced, either automatically if the subsystem contained a hot spare drive, of by user intervention during 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 new drive.

Max. "Disk Striping” , block striping is used, which yields higher performance than with the individual disk drives. * There is no redundant function.
[ Multi-SCSI Korma t support Introduction The Disk Array provides one Ultra Wide SCSI channel for connecting to your host system.
