In Linux, how does one set RAID 10 to ensure high-performance and fault-tolerant disk input/output? (1)
RAID 10, also known as RAID 1 + 0 or image strip) array combines the features of RAID
The disk array is made up of many inexpensive disks, combined into a large disk group, which uses individual disks to provide data with the added effect to improve the performance of the entire disk system. Using this technology, the data is cut into many sections, stored on each hard drive, even if there is a piece of damage, no data loss, and can continue to use.

0 + 1 as long as one hard disk is damaged, another hard disk of RAID 0 in the same group will also stop operating, with only two hard disks operating, with low reliability. Therefore, RAID 10 is far more commonly used than RAID 01. most retail boards support RAID 0/1/5/
also keeps critical applications up and running. Advantage: Data read performance is improved, and data write performance is no different than a single disk. 100% data redundancy means that there is no need to rebuild data in the event of a disk failure. It is important to note the inefficient use of disk capacity-the highest cost for all RAID types (100%).3,RAID10 Features: RAID-

In Linux, we use the mdadm tool to manage RAID. Mdadm is the abbreviation of Multiple Devices Admin (the alias of Linux Soft RAID is
development of computer technology in recent years, the CPU speed of PCs has entered the GHz era. The hard disks of the IDE interface are also lagging behind, and ATA66 and ATA100 hard disks are successively released. This makes it possible to apply RAID technology to low-end or even personal PCs. RAID is usually implemented by the RAID Controller in the hard di
Aid DefinitionRAID (Redundant Array of independent disk independent redundant disk array) technology is the University of California, Berkeley, 1987It was initially proposed to combine small and low-cost disks to replace large and expensive disks. At the same time, it was hoped that access to data would not be damaged when the disk fails.Develop a certain level of data protection technology.
the same as those on a single hard disk. The difference is that the storage speed of the disk array is much higher than that of a single hard disk, and automatic data backup can be provided.Two features of RAID technology:
First, speed
Second, security
Thanks to these two advantages, RAID technology was applied to hard drive systems with SCSI interfaces in advan

hard disk. Considering the service life of each disk, any disk in the array may be faulty. From a statistical perspective, the failure rate of N disks in the array is N times higher than that of a single disk. Based on the above factors, if the number of disks in the array is reasonable and the average MTBF of these disks is short, the expected service life of t
