A-12Adaptec Storage Manager Pro User’s GuideStripe Set of RAID 5 Sets (RAID 0/5)RAID technology allows you to create arrays that contain otherarrays. (Also known as multilevel arrays.) A stripe set of RAID 5 setsis an array made up of two or more equal-sized RAID 5 sets. Thedata in a stripe set of RAID 5 sets is redundant.Figure A-8 represents a stripe set of RAID 5 sets created from twoequal-sized RAID 5 sets (A and B) and striped across six drives.Each RAID 5 set is made up of three equal-sized partitions on threeseparate drives. The free space of the larger drive is not used.Figure A-8. Stripe set of RAID 5 setsThe stripe set of RAID 5 sets is the top-level array, and RAID 5 sets Aand B are the underlying arrays.Other types of multilevel arrays exist, though the stripe set of mirrorsets offers the best redundancy of any array type.❒Partition APartition A Partition B Partition B Partition CRAID 5 Set A8 GB16 GBStripe Set of RAID 5 SetsChunksChunks 1,3,5,7...RAID 5 Set B8 GBChunks 2,4,6,8...Drive 1Partition CDrive 2 Drive 3 Drive 4 Drive 5 Drive 61,2,3,4,5,6,7,8,9...4 GB 4 GB 4 GB 4 GB 4 GB 4 GBFree Space*P = ParityChunks Chunks Chunks Chunks Chunks Chunks1,7,P*,13...
