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 multiple smaller hard disks into a larger disk, and also to protect data. Now the disk array is divided into:

However, RAID 6 requires more disk space allocated to parity information and a greater write loss than RAID 5, so "write performance" is very poor. Poor performance and complex implementations allow RAID 6 to be rarely used in practice.650) this.width=650; "title=" DSS074 "style=" border-top:0px;border-right:0

Two independent parity systems use different algorithms, and the data is very reliable, even if two disks fail at the same time without affecting the use of the data. However, RAID 6 requires m

Terms RAIDAn independent redundant disk array is a storage term. to improve performance and reliability, multiple disks are combined, which is a storage unit from the outside. the detailed introduction to RAID is not within the scope of this document; Wikipedia article "RAID" provides better content.

three or more disk implementations, and when any piece of disk has data corruption, the data can be recovered using the same bit check code (parity). For example, 1+2=3,3 can be seen as a parity, and when data 1 is damaged, it can be destroyed by 3-2=1 (of course, the concrete implementation is certainly more complicated than this). Note that RAID5 only supports the destruction of a piece of disk.3.RAID Pre-diskIn order to be able to externally a dam
Data security is one of the most important issues in the use of computers. Generally, Hard Disk Mirroring technology is used in the server environment to achieve dual data backup. We can also use this technology in Linux. In Linux, Raidtools can be used to mirror not only two hard disks, but also soft RAID 0, RAID 1, and RAID 5. It is soft
Data security is one of the most important problems people use in computers. Typically, a hard disk mirroring technique is used in a server environment to achieve a dual backup of the data. Also, we can use this technology in a Linux environment. In the Linux environment, the use of raidtools tools, not only can be two hard disk mirroring, but also can make soft RAID0, RAID1, RAID5.
