Disk fault tolerance means that data integrity and data processing capabilities can be guaranteed when a hard disk error or hard disk failure occurs in the subsystem. The RAID control card implements this function on RAID 1, 5, 6, 10, 50, and 60 through redundant hard disk groups. In RAID 1, since the data is […]

[Linux]What is RAID? RAID array
1. RAID 1.1 RAID disk display introduction is the abbreviation of Redundant Array of Independent Disks, the Chinese abbreviation is independent redundant disk array Combine multiple independent physical hard disks in different ways to form a hard disk group (logical hard disk), thereby providing higher storage performance and data backup technology than a single hard […]
IL braider — Fody
Introduction The name of this project “Fody” comes from the small bird (Fody) belonging to the weaver family (Ploceidae), which itself means weaving. Code base address of the core Fody engine: https://github.com/Fody/Fody This is how it is introduced on Github: “Fody” is an extensible tool for weaving .NET assemblies.

Linux disk management (partitioning, SWAP, LVM, RAID, hot backup)
Partition Concept: Data Organization and Management: Disk partitioning allows hard disk space to be divided into logical units, which helps organize and manage data more efficiently. Different types of data can be stored in different partitions, making the data easier to maintain and back up. Improving performance: Partitions can be used to separate operating system […]

7.RAID0/RAID1/RAID3/RAID5/RAID6/RAID10/RAID50
1.Basic knowledge of raid The development of traditional RAID technology. In traditional computer storage systems, storage work is usually completed by the computer’s built-in disk. There are many problems with traditional built-in storage: Chassis space limits the number of hard drives. Inconvenient for expansion, sharing and backup Low reliability and high risk of data loss […]
