Riad 1 requires two hard drives, I added 2 80G hard drives to the VPS. In the system, use the Fdisk–l command to viewSecond, install MdadmMDADM is the abbreviation of multiple devices admin, which is a standard software

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. RAID has different common levels, so that the consolidated disk has different functions:=============================================================================================================== ===========================

Getting started with Linux: disk array (RAID) RAID is a Redundant Array of low-cost Disks (Redundant Array of Inexpensive Disks). RAID technology combines individual Disks into a logical hard disk in different combinations, this improves the disk reading performance and data security. Different combinations are identified at the

Brief Introduction to RAID Disk Arrays RAID is the abbreviation of "Redundant Array of Independent Disk". It is translated as a Redundant Array of Independent Disks, which is actually the storage, access, and backup technology of disks. Before talking about RAID, let's take a look at some basic knowledge about memory. 1. Storage Basics When it comes to memory, as

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

When it comes to disk arrays (raid,redundant array of independent disks), it is now almost one of the technologies that network administrators must master, especially small and medium-sized enterprises, because disk arrays are widely used and are one of the main scenarios for current data backup. However, many network administrators only in various media to see the relevant theoretical knowledge, but did not see some of the actual disk array configura

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

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

Today's operating systems, whether Windows or Linux have RAID capabilities, RAID is divided into hardware RAID and software RAID, hardware RAID is through the RAID card, software RAID i

Background: RAID is a Redundant Array composed of multiple low-cost disks. It appears as an independent large storage device in the operating system. RAID can give full play to the advantages of multiple hard disks, increase the speed of the hard disk, increase the capacity, and provide Fault Tolerance functions to ensure data security. In the case of any disk failure, you can continue to work, the disk wil
