Differences between simple volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5

Hard disk partition, there are three kinds, primary partition, extended partition, logical partitionA hard disk primary partition has at least 1, a maximum of 4, and an extended partition can be no more than 1. and the primary partition + extended partition must not exceed 4 total. A logical partition can have several.The extended partition cannot be used directly, it must be used to separate the logical partition, and the logical partition exists in the extended partition. Logical partitions ar

Server RAID 5 Data Recovery tutorial diagram

The topic is discussed in the popular RAID 5 architecture. The principle of RAID is to save data to each hard disk with bit striping and current main block striping, when the hard disk is damaged by XOR, then there will be parity blocks and data in other hard drives. The data blocks of the stripe magnetic field is computed and the information rebuild is reconstru
