Choosing Your Array Type I Stripe set (RAID 0)-An array made up of two or more drives. The stripe set distributes, or stripes, data evenly across the partitions in equal-sized sections called chunks. I Mirror set (RAID 1)-An array made up of two drives. A mirror set stores and maintains the same, or redundant, data in each of its two partitions. I RAID 5 set-An array that is similar to a stripe set, except that it uses parity to provide redundancy. A RAID 5 set must be made up of at least three equal-sized partitions. One chunk is used for parity data for each set of chunks striped across the partitions. The parity chunk is distributed across all drives containing partitions of the RAID 5 set. I Stripe set of mirror sets (RAID 0/1)-An array made up of two or more equal-sized mirror sets that also stripes the data across all drives. I Stripe set of RAID 5 sets (RAID 0/5)-An array made up of two or more equal-sized RAID 5 sets that also stripes the data across all drives. For more detailed descriptions of each array type, see Appendix A, Storage Concepts. B-3
