Redundant Array of Independent Disks It is an array of multiple independent hard disk drives that provides high performance and fault tolerance The RAID controller imple ments several levels of the Berkeley RAID technology An appro priate RAID level is selected when the volume sets are defined or created This decision should be based on the desired disk capacity data availability fault tolerance or redundancy and disk performance The following section discusses the RAID levels supported by the RAID controllers The RAID controllers makes the RAID implementation and the disks physical configuration transparent to the host operating system This means that the host operating system drivers and software utilities are not affected regardless of the RAID level selected Correct installation of the disk array and the control ler requires a proper understanding of RAID technology and the concepts RAID O RAID 0 also referred to as striping writes stripes of data across multiple disk drives instead of just one disk drive RAID 0 does not provide any data redundancy but does offer the best High speed data throughput RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the array Disk strip ing enhances performance because multiple drives are accessed simultaneously the reliability of RAID level 0 is less because the entire array will fail if any one disk drive fails 156 APPENDIX AO Al A2
