ALSO CALLED: Array, R A I D Array, Storage Arrays, Arrays, RAID Array, Redundant Array of Inexpensive Disks, R A I D, Redundant Array of Independent Disks, Disk Arrays
DEFINITION: Double-parity RAID (redundant array of independent disks), also called diagonal-parity RAID, Advanced Data Guarding (RAID_ADG), or RAID-6, is a method of protecting against multiple storage drive failures by creating two sets of parity data on an array of hard disks. In a conventional RAID, data is stored in different places on multiple hard disks, thereby increasing the aggregate mean time between  …

RAID DEFINITION (continued): …  failures (MTBF) and improving the fault-tolerance. In the approach known as RAID-4, the number of bits in data blocks on multiple disks is added up, and the total is kept on a disk called the parity disk. If a drive fails, data recovery is facilitated by using the bits stored on the parity disk and bits remaining on the surviving drives. In RAID-5, the parity information is stored diagonally across all the disks in the RAID set. If a single drive fails, the original data is calculated from the parity information remaining on the surviving disks in the set.Because hard disk storage capacity continues …
