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)

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

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

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

Brief description of RAID

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

The disk array can be generated before or after the system is installed, which is considered a (large) hard drive with fault tolerance and redundancy. The disk array can not only join a ready-made system, it can support capacity expansion, the method is very simple, only need to join a new hard drive and execute some simple instructions, the system can take advantage of this new capacity in real time. · types and Applications of RAIDThe IDE and SCSI are two different interfaces for computers, w
