Redundant Array Of Independent Disks - Whitepaper On RAID
White Papers RAID (Redundant Array of Inexpensive or Independent Disks) is an important component for servers on a critical enterprise or workgroup network. RAID provides crash-proof hard drive systems. RAID technology makes data more accessible by preventing...

What Is RAID
White Papers The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple inexpensive disk drives into an array of disk drives to obtain performance, capacity and reliability that exceeds that of a single large drive.

The Time Has Come To Switch To RAID 10
White Papers RAID (Redundant Array of Independent Disks) is the standard for combining multiple independent hard drives to form one large logical array. Various RAID levels define the way data is distributed and redundant capacity is implemented.

Striping In A RAID Level 5 Disk Array
White Papers Past research has studied how to stripe data in non-redundant (RAID Level 0) disk arrays, but none has yet been done on how to stripe data in redundant disk arrays such as RAID Level 5, or on how the choice of striping unit varies with the number...

RAID-II: A High-Bandwidth Network File Server
White Papers The RAID (Redundant Arrays of Inexpensive Disks) group at U. Berkeley built a prototype disk array called RAID-I. The bandwidth delivered to clients by RAID-I was severely limited by the memory system bandwidth of the disk array's host workstation.

Hardware RAID Vs. Software RAID: Which Implementation Is Best For My Application?
White Papers In the last couple of years, RAID (Redundant Array of Independent Disks) technology has grown from a server option to a data protection requirement. The first implementations of RAID in 1990 were very expensive controller boards with high...

Low-Cost And Easy-to-Use Hardware RAID 5 Solutions
White Papers RAID (Redundant Array of Independent Disks) technology has been proved as the best technology to protect large-volume data while provide excellent performance. There have been a variety of implementations of RAID, and various products have been...

Using NvSRAMs In RAID Controller Applications
White Papers Just like the goals of RAID (Redundant Arrays of Independent Disk Drives), Simtek nvSRAMs provide EDAP (Extended Data Availability and Protection) by protecting their data and providing immediate access to their data despite other failures in the...

Let's Talk About RAID
White Papers RAID stands for Redundant Array of Inexpensive (or sometimes RAID is a method of combining several hard drives into one logical unit. Independent") Disks. It can offer fault tolerance and higher throughput levels than a single hard driveor group of...

RAID Theory: An Overview
White Papers RAID stands for Redundant Array of Inexpensive (or Independent) Disks. RAID is something all have heard about but very few understand, at least fully. There are a dozen or so theories as to why RAID was conceptualized, but the most accepted reason...

Extreme RAID: How STORM Xtreme Array Delivers True "No Single Point Of Failure" Data Availability For Mission-Critical Applications
White Papers They offer multiple, redundant fibre channel connections from the RAID controller to the disks and hosts to survive fibre channel connection or adapter failures. RAID storage systems have always been regarded as inherently fault tolerant.

StoreVault And RAID-DP
White Papers The increased dependence on disk storage and the need for higher levels of reliability, availability and performance has led to a dramatic increase in the use of Redundant Array of Independent Disks or RAID technology.

RAID 5 For Data Resilience - The Case For Intelligent RAID Controllers
White Papers Among these is the implementation of Redundant Array of Inexpensive Disks (RAID) 5 to enable data storage arrays with a cost-effective mix of disk striping with rotating parity. This foundational technique is, however, processor-intensive and tests...

RAID Explained
White Papers The acronym 'RAID' stands for Redundant Array of Independent (or Inexpensive) Disks. It is generally recommended that all disks in a RAID should be identical (or at the very least, the same size and speed).

IDE RAID On The Desktop
White Papers The effect of this trend is best explained in Patterson, Gibson, and Katz's opening of their 1988 "A Case for Redundant Arrays of Inexpensive Disks (RAID)" paper, introducing RAID. Their paper proposed several levels of RAID, all aimed at...

Preemptive RAID Scheduling
White Papers These storage systems are often implemented using Redundant Arrays of Independent Disks (RAID). The paper presents an architecture for QoS-aware RAID systems based on Semi-preemptible IO. The paper shows when and how to preempt IOs to improve the...

Picking Apart RAID
News Anyone who has worked with RAID has heard the term "parity". Since the I/O load is spread across each disk, this RAID level performs efficiently both reading and writing data to and from the array. Parity is a form of error correction commonly used...

Disk Storage Faces Gloomier Outlook
News External, controller-based RAID disk storage products use "redundant array of independent disks" technology to prevent data loss when a disk drive fails. Gartner on Thursday said sales of external, controller-based RAID disk storage hit $3.23bn...
