G-RAID: A Green RAID Mechanism for enhancing Energy-Efficiency in Massive Storage System

Auto RAID hierarchical storage system

once the total number of disks gets large, it becomes more cost-effective to employ an array controller that uses some form of partial redundancy (such as parity) to protect the data it stores. Such RAIDs (for Redundant Arrays of Independent Disks) were first described in the early 1980s [Lawlor81, Park86], and popularized by the work of a group at UC Berkeley [Patterson88, Patterson89]. By sto...

Swift/RAID: A Distributed RAID System

The Swift VO architecture is designed to provide high data rates in support of multimedia type applications in general-purpose distributed environments through the use of distributed striping. Strþing techniques place sections of a single logical data space onto multiple physical devices. The original Swift prototype was designed to validate the architecture, but did not provide fault tolerance...

RAID: A Personal Recollection of How Storage Became a System

A Tutorial on RAID Storage Systems

RAID storage systems have been in use since the early 1990’s. Recently, however, as the demand for huge amounts of on-line storage has increased, RAID has once again come into focus. This report reviews the history of RAID, as well as where and how RAID systems fit in the storage hierarchy of an Enterprize Computing System (EIS). We describe the known RAID configurations and the advantages and ...

Reliability Modelling of Whole RAID Storage Subsystems

Reliability modelling of RAID storage systems with its various components such as RAID controllers, enclosures, expanders, interconnects and disks is important from a storage system designer's point of view. A model that can express all the failure characteristics of the whole RAID storage system can be used to evaluate design choices, perform cost reliability trade-o s and conduct sensitivity ...
