Because of this, a new technology--raid was born.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 hard disk array.The basic idea is to combine a number of relatively inexpensive hard drives into a hard disk array to achieve

First, the purpose of the experiment1. Mastering the implementation method of soft raid in Linux system;2. Master the configuration process of RAID5;3. Be familiar with RAID, 5 characteristics through experiment.Second, the contents and steps of the experiment 1. Create a Linux in VMware.2. Add the Linux 4 virtual disk (select SCSI type, 2G).3, the use of Madam in Linux to create RAID5, thre

Article Title: General thread-software RAID in the new Linux2.4 kernel, Part 2. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. By Daniel Robbins 　　 Install RAID-1 in the production environment 　　 The new 2.4 kernel has finally been released. now we should find an idle P

First, RAID introductionRAIDAn inexpensive redundant disk array (redundant Array of inexpensive Disks), fromLinux 2.4kernel start,Linuxsoftware is availableRAID, you don't have to buy expensive hardwareRAIDcontrollers and accessories (typically medium-and high-block servers provide such devices and hot-swappable hard drives) can improve read and write performance by parallel processing of multiple independent I/O requests, and increase the reliability

Classification: A RAID definitionRAID (Redundant array of independent disks independent redundant disk array) technology is the University of California, Berkeley, 1987, was originally designed to combine small low-cost disk to replace the large expensive disk, while the disk failed to make access to the data will not be compromised A certain level of data protection technology has been developed. RAID is

RAID Mode IntroductionThe Orico 3559RUS3 HDD enclosure provides five types of disk array build modes, including RAID 0, Raid 1/10, RAID 3, RAID5, Combine, which have different functions, as explained below.RAID, the English "Redundant Array of independent Disks" abbreviation, the Chinese name is called "Redundant Array

Raid, short for Redundant Arrays of Independent Disks, is cheap in Chinese ※redundant disk array. Disk arrays are also divided into software raid and hardware raid. the soft array is achieved by the software program and the CPU of the computer. because the software program is not a complete system, it can only provide the most basic

Intel S5000VSA (SAS) motherboard setup RAID stepsI recently personally installed a server, with the Intel S5000VSA 4DIMM motherboard, because in the installation process did not notice some details, so in the installation encountered some problems, and then after everyone's research and discussion, finally successfully solved these problems, in order to accumulate experience, Also in order to allow other colleagues to avoid the network, save time, spe

Original: http://blog.chinaunix.net/uid-639516-id-2692517.htmlClassification:A RAID definitionRAID (Redundant array of independent disk independent Redundant array) technology was proposed by the University of California, Berkeley, in 1987, initially to combine small, inexpensive disks in place of large expensive disks, while hoping that the disk will fail without damaging access to the data Development of a certain level of data protection technology

Brief introductionRAID is a noun that we can often see. But because rarely can experience in the actual environment, so it is difficult to have a very clear understanding and grasp of its principle. This article will introduce and summarize the raid technology in order to clarify its concept as much as possible.RAID is all called Redundant Array of independent disks (redundant array of independent Disks), the basic idea is to combine a number of relat

RAID 10 (also called a raid 1+0 or mirrored stripe) array combines the functionality features of RAID 0 and RAID 12 to provide high-performance, fault-tolerant disk input/output operations. In RAID 0, read/write operations execute across multiple drives, and in

1. See how many hard drives are available#fdisk-LWell, in general, leave the system disk, the other disks if the size of the same, all together to do a raid.2. Decide what type of RAID to do.raid-0, Raid-1, raid-5?If you have three disks (or more) of the same size, it is highly recommended to

comparison of RAID common levels Characteristics Hard disk and capacity Performance and safety Typical applications RAID 0 Used for parallel storage, that is, strips. The principle is to divide the continuous data into several pieces and then distribute it to each hard disk in the array. Any one disk failure will result in data loss. Number of hard disks: one

Memo Http://baike.baidu.com/view/7102.htm RAID is the abbreviation for "Redundant array of independent disk", which is an independent redundant array of disks. Redundant disk array technology was born in 1987 by the University of California, Berkeley.
