Sometimes CentOS Linux kernel does not have a RAID card driver, can only be loaded with floppy disk drive, in fact, there are other methods, as long as the appropriate driver to find the official, the RAID card is now a lot of brands, but most of the independent RAID card for Highpoint,3ware, Adapter,lsi,promise, and s

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

Transferred from: http://www.linuxidc.com/Linux/2015-08/122191.htmRAID means a redundant array of inexpensive disks (redundant array of inexpensive Disks), but now it is known as a redundant array of independent disks (redundant array of independent Drives). Earlier a very small disk was very expensive, but now we can buy a larger disk cheaply. Raid is a collection of disks that are put together to become a logical volume.Understanding

Introduction RAID, English is all called: Redundant Arrays of independent Disks, Chinese translation: Independent fault-tolerant disk array, formerly known as a fault-tolerant low-cost disk array, is now generally referred to as a disk array. The thing is presented by UC Berkeley, which can be used to integrate multiple smaller hard disks into a larger disk, and also to protect data. Now the disk array is divided into: software

As you know, hardware RAID solutions are fast, stable, and can effectively deliver high levels of hard disk availability and redundancy, but high prices are daunting. Fortunately, Windows 2003 provides built-in software RAID capabilities, and soft RAID enables RAID-0, RAID-1

In linux, you can view the raid information of a server. 1. for software raid, you can use cat/proc/mdstat md1: active raid1 sdb3 [1] sda3 [0] 480572352 blocks [2/2] [UU] md3: active raid1 sdb2 [1] sda2 [0] 1952704 blocks [2/2] [UU] md2: active raid1 sda1 [0] sdb1 [1] 194496 blocks [2/2] [UU] I made a soft RAID 1 (sda, sdb two hard disks ). soft

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

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

Two days ago, a Dell r720 installed rh5.1 for business needs. Both the Dell official website and the utilty disc support rh5.8 or above. The hard disk cannot be found at the partitioning step when the disc is installed. That is to say, the ramdisk of the initrd of the disc does not have the driver of the RAID card, The procedure is described as follows: This machine is low-end RAID card, Perc H310 Mini, dow

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,

Application of RAID disk array RAID, which is generally translated as a Disk array and its full name is Redundant Arrays of Inexpensive Disk. It was initially conceived as a project by a research team at the University of California, Berkeley, they hope to build a cheap and highly available disk array through a large number of cheap hard disks. However, the development of

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
