  author={Spencer W. Ng},
Redundant disk array architecture provides fault tolerance against disk drive failures. However, a storage subsystem consists of more than just disk drives. There must also be controllers for interfacing with the disk drives, cabling for providing data/control paths, power supplies, etc. For the subsystem to be fault tolerant, it must also be able to tolerate failure in any one of these components. While currently known array architectures can be designed to be tolerant to single failure in the… CONTINUE READING
