Introduction RAID Level 1 : " Disk Mirroring " High Data Reliability Physical Optional O®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 falls, ray management software simply directs all application requests to the surviving member.
Introduction ® RAID level § arrays have unique performance characteristics : + The data can be recalculated or regenerated, using parity, when any drive in the array falls.
Supported RAID Levels Based on the needs of a Disk Array's capacity, data availability, and overall performance, you can select a proper RAID level 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.

Introduction RAID Level 5 : " Independent Access Array with Rotating Parity High Data Reliability & Transfer Capacity Disk 1 Disk Disk Disk Disk Disks Physical P: Parity When RAID Level 5 technology Is combined with cache memory to improve Hts wilt performance, the result can be used in any applications where general purpose disks would be suitable. For read only or read mostly application 1/0 loads, RAID Level 5 performance should approximate that of a RAID Level 0 any.
Introduction ® RAID level 0 arrays are not particularly suitable for © + Applications which make sequential requests for small amount of dots. These applications will spend most of their VO time waiting for disks to spin, whether or not they use steeped arrays as storage media. + Applications which make synchronous random requests for small amounts of data.
Introduction General RAID Once 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 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 . Arena includes the following features Easy Operation As everyone knows, conventional Disk Arrays are designed for experienced computer specialists.
