7. APPENDIX Appendix E RAID Concept RAID Set A RAID set is a group of disks connected to a RAID controller A RAID set contains one or more volume sets The RAID set itself does not define the RAID level 0 1 1E 3 5 6 10 30 50 60 etc the RAID level is defined within each volume set Therefore volume sets are contained within RAID sets and RAID Level is de fined within the volume set If physical disks of different capaci ties are grouped together in a RAID set then the capacity of the smallest disk will become the effective capacity of all the disks in the RAID set Volume Set Each volume set is seen by the host system as a single logical device in other words a single large virtual hard disk A volume set will use a specific RAID level which will require one or more physical disks depending on the RAID level used RAID level refers to the level of performance and data protection of a volume set The capacity of a volume set can consume all or a portion of the available disk capacity in a RAID set Multiple volume sets can exist in a RAID set For the RAID controller a volume set must be created either on an existing RAID set or on a group of available individual disks disks that are about to become part of a RAID set If there are pre existing RAID sets with available capacity and enough disks for the desired RAID level then the volume set can be created in the existing RAID set of the user s choice RA
