RAID level features, refer to Wikipedia.Redundant array of independent hard disks (RAID, Redundant array of independent Disks), formerly redundant Array of Inexpensive disks (Redundant array of inexpensive Disks), referred to as disk arrays. The basic idea is to combine a number of relatively inexpensive hard drives into a hard disk array to achieve even more expensive, large-capacity drives. Depending on t

Raid is the abbreviation of Redundant Array of Independent Disks ). [Note: A disk array is a technology used by a hard disk controller to control the connection between multiple hard disks. This allows read/write synchronization between multiple hard disks, reduces errors, and increases efficiency and reliability. This technology is implemented by the disk array product. The physical form is that a long square body contains several hard disks and oth

RAID (Redundant Array of Inexpensive Disks) is a Redundant Array of cheap Disks. The basic idea of RAID is to combine multiple cheap small disks into a single disk group, so that the performance can reach or exceed a large and expensive disk. Currently, RAID is divided into two types: hardware-based RAID and software-b

Source: yourblog.org)RAID technology detailsRAID is called the Redundant Array of Disks. It is the abbreviation of "Redundant Array of Independent Disks" (originally "Redundant Array of cheap Disks. In 1987, Patterson, Gibson, and Katz were defined in an article by the UC Berkeley branch. RAID array technology allows you to group A series of disks to achieve data redundancy required for data protection, as

Technical Specifications(1) Introduction of RAID technical specification 　　The first development of redundant disk array technology was designed to combine small, inexpensive disks to replace large, expensive disks, in order to reduce the cost of mass data storage, but also want to use redundant information, so that the failure of the disk will not lose access to the data, thereby developing a certain level of data protection technology, and can imp

The full name of the disk array is: Redundant Arrays of Inexpensive Disks, raid, which roughly means a cheap redundant disk array. Raid can use a technology (software or hardware) to integrate multiple smaller disks into a larger disk device. This larger disk not only expands the storage space, data protection is also available. Raid makes the integrated disk ha

Matrix RAID is a separate example of this because of its special disk allocation concept: For example, using 2 120G disks to make up a raid with a total capacity of 240G, set up a RAID 0, manually specify a disk capacity of 1 to 238G RAID 0 mode, and then use the remaining disk space to establish a

Implementation of Software raid in Linux Author: Unknown Source: Unknown As a network operating system, the redundant disk array (RAID) is one of the essential functions. Starting from the Linux 2.4 kernel, Linux provides software raid, eliminating the need to purchase expensive hardware raid controllers and accessori

Redundant Arrays of Independent Disks (RAID) indicates a disk array with low cost and redundancy capabilities. The principle is to use arrays as disk groups, and use them in combination with the Design of Distributed Data arrangement to improve data security. A disk array is a combination of many Inexpensive Disks into a disk group with a large capacity. The addition effect produced by the data provided by individual disks improves the efficiency of t

Basic Linux RAID operations RAID stands for "A Case for Redundant Arrays of Inexpensive Disks (RAID)", known as A "cheap Redundant disk array", which was published by UC Berkeley in 1987. The main idea of RAID is to make several small physical disks into a large-capacity virtual storage device to improve the Read and W

There are two ways that a disk array can be implemented, that is, "software arrays" and "hardware arrays."A software array is the Disk management function provided by the network operating system itself to configure multiple hard disks on a connected common SCSI card into a logical disk to form an array. The software array can provide data redundancy, but the performance of the disk subsystem will be reduced, some of the reduction is still relatively large, up to 30%.The hardware array is implem

disk array-the integration of multiple disks into a larger disk through a certain technology, not only increased capacity, but also the data on the disk has the function of maintenance, recovery, read faster.

Overview raid is the abbreviation of "Redundant Array of independent disk ".Independent redundant disk array. The redundant disk array technology was born in 1987 and was proposed by the University of California at Berkeley.　　Raid disk array (Redundant Array of Independent Disks)A simple explanation is to combine n hard disks with RAID Controller (hardware, softw

RAID technology mainly includes RAID 0 ~ Raid 50 and other specifications have different focuses. common specifications include: 　　RAID 0: RAID 0 continuously splits data by bit or byte and reads/writes data on multiple disks in parallel. Therefore,

1.1 raid was proposed by Professor D. A. Patterson of the University of California at Berkeley in 1988. Raid is the abbreviation of redundent array of Inexpensive Disks. It is also called "disk array ". Later, the letter I in raid was changed to independent, and raid became an "independent redundant disk array". Howeve
