Redundancy, fault tolerance Increased capacity Increased performance Mirroring : Mirroring The easiest way to get high availability Half the size Higher read performance Striping : Striping Higher performance Distributed across disks Work in parallel Parity : Parity Improve the availability Less waste of space RAID 0 : RAID 0 Striping Highest performance Lower availability RAID 1 : RAID 1 Mirroring High availability Low computing power RAID 2, 3, 4 : RAID 2, 3, 4 Parity High performance High availability RAID 5 : RAID 5 Parity with distribution Higher performance than level 1-4 High availability Most used RAID level Combinations of different levels : Combinations of different levels Combine two levels and get the advantages from both Either hardware driven, software driven or a combination of both Examples: 0+1, 1+0, 0+3, 3+0, 0+5, 5+0, 1+5, and 5+1. Alternatives to RAID : Alternatives to RAID Single Large Expensive Disk (SLED) Redundant Array of Distributed Disks (RADD) More alternatives: 2D-RADD, C-RAID, RO WB-optimistic and RO WB-pessimistic The End : The End First RAID system.
