RAID Basic Concepts, Special terminology introduction We offer RAID cards to support a variety of commonly used RAID levels, such as 0,1,5,10,50, you can choose based on the importance of the data, before starting to use the RAID card, we hope you can have a deeper understanding of the following concepts, so as

increases fault tolerance.Level classification for RAID:RAID 0: The data is evenly distributed across the array's disks in strips, so that the system has data requests that can be executed in parallel by multiple disks, each of which performs its own portion of the data request. The parallel operation on this data can make full use of the bus bandwidth, and significantly improve the overall disk access performance.Hardware requirements: Minimum of 2 disksPerformance advantages: Very high disk r

What problems should individual users pay attention to when building RAID, or a disk array?1. Q: What RAID solution should I choose, and the motherboard With RAID function? RAID Controller? Or software RAID?A: In fact, RAID soluti

Early due to raid is often used to combine some inexpensive SATA interface hard disk devices to complete redundancy.So the early full name is: redundantarray of independent Disks (independent redundant disk array). The primary function of RAID is to combine multiple hard disks on the motherboard in a specific way, organized into a logical whole with specific characteristics, and then output to the operatin

Raid 10: Make at least four hard disks into RAID 1. If there are four hard disks, there will be two to rand1 disks. If there are eight hard disks, there will be four to raid 1 disks, the biggest purpose of raid1 is to ensure high data security and high read/write speed, but to sacrifice half of the disk space. If the number 12345678 is written to a request, the w

Raid learning and basic knowledge v0, 1B Author:Small PFrom:Linuxsir. orgAbstract:Data damage and loss caused by various disasters and errors cause losses and inconvenience to people. Data on personal and website servers must be backed up. Raid is a feasible and effective method. Raid is divided into soft RAID and hard

The raid:redundant Arrays of inexpensive disk is an inexpensive redundant array of disks that can be organized in different ways to improve IO capabilities, or improve durability, for multiple hard drives. RAID can be divided into soft raid and hard raid, soft raid through software implementation, hard

As we all know, CPU chip and graphics subsystem performance is soaring, but the corresponding disk subsystem performance is becoming more and more serious performance of the overall system bottlenecks. While disk technology is ata/100 today DMA66 tomorrow, none of these specifications can fundamentally improve the capabilities of the disk subsystem. It's only raid (here we refer specifically to IDE RAID tec

In the current era of large data explosion, more and more enterprises pay more attention to the data security of enterprises, the integrity of data, then how to protect the enterprise data bank security, lossless? Then we use RAID technology, which is now a very hot virtualization, cloud computing, the bottom of the raid storage is used to complete. So what is RAID
