A-1Appendix A: Understanding RAIDA.1 RAID OverviewThe controller supports eleven types of RAID: RAID 0, 1, 3, 5, 6, 10, 30, 50, 60, JBOD and NRAID.

AppendixA-2A.2 RAID 0RAID 0 links each drive in the array to form one large drive. Storage capacity is determined by the smallest drive in the array

AppendixA-3A.3 RAID 1RAID 1 is commonly referred to as disk mirroring as all data is duplicated on two or more disks. This provides a high access ra

AppendixA-4A.4 RAID 3In RAID 3, all data is divided into pieces, after which the system calculates the parity of these pieces. The pieces are writte

AppendixA-5A.5 RAID 5With RAID 5, the system calculates parity from data on three drives. If one of the drives fails, parity data can be used to reb

AppendixA-6A.6 RAID 6RAID 6 stripes data and parity data across an array of drives, as with RAID 5, and calculates two sets of parity information fo

AppendixA-7A.7 RAID 10RAID 10 arrays are formed by striping data across RAID 1 sub-arrays. This offers better performance than RAID 1 alone but does

AppendixA-8A.8 RAID 30RAID 30 arrays are formed by striping data across RAID 3 sub-arrays. This offers better performance than RAID 3 alone but does

AppendixA-9A.9 RAID 50RAID 50 arrays are formed by striping data across RAID 5 sub-arrays. Striping helps increase capacity and performance without

AppendixA-10A.10 RAID 60RAID 60 arrays are formed by striping data across RAID 6 sub-arrays. Striping increases the system capacity and performance

AppendixA-11A.11 JBODJBOD (“Just a Bunch of Disks”) focuses on individual drives. The operating system sees each drive as an individual drive in JBO

AppendixA-12A.12 NRAIDNRAID (“None RAID”) combines all drives as one simple logical volume. The capacity of this volume is the total capacity of the
