Often someone communications raid, but it does not know its so dye, today I will be an example of Internet cafes to explain.With the expansion of Internet cafes, internet cafes will increase the number of computers, Internet users also increased, the speed of data access to the server will become a new bottleneck, many customers began to complain about the server on-demand film comparison card, game upgrade slow and other issues, if not to take releva

The difference between disk array raid and hardware RAID and software raid on the Linux learning path

We know that the capacity of a single disk storage data is limited, in order to increase the capacity of the disk, we can combine a number of smaller disks together to form a larger disk device, which is a raid (stand-alone disk array), RAID can not only improve the storage capacity of data, but also improve the data protection function, Different levels of

A detailed explanation of the disk array RAID technology principles

1.RAID Description RAID is an abbreviation for the English Redundant Array of Inexpensive disks, abbreviated as a redundant array of inexpensive disks. Simply put, RAID is a combination of multiple separate hard disks (physical hard disks) in different ways to form a hard di

Comprehensive introduction to RAID disk array technology

In the early days of computer development, the price of "large capacity" hard disk is still quite high, the main way to solve the problem of data storage security is to use devices such as tape drive to backup, although it can guarantee the security of data, the work of lookup and backup is quite tedious. In 1987, three engineers, Patterson, Gibson and Katz, published a paper entitled "A case of redundant array of inexpensive disks (redundant

Software disk array (software RAID) Introduction

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 multip

Configure a disk array (RAID) on the rhel6 System)

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

Principle of RAID disk array

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 addi

Teach you to install the disk array: Build RAID requires several hard drives _ server other

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
