this time, the third and fourth disks are idle. When B data is written to the third Disk in a certain band, and B data is checked in the fourth disk, in this way, both data a and data B can be read and written at the same time. VII. Raid 6 Raid 6 adds a verification area on the basis of RAID 5, each of which has two verification areas. They use an unused verification algorithm to improve data reliability.

CentOS startup level: init 0, 1, 2, 3, 4, 5, 6 This is a long-time knowledge point, but I have been confused all the time. Today I am trying to understand it .. 0: stopped 1: Maintenance by root only 2: multiple users, cannot use net file system 3: more users 5: Graphical 4:

In the PHP language, for digital characters and numbers how to participate in the operation, in specific cases will be determined, for example: echo "3+4+5"; Results: 3+4+5. Because it is treated as a string. When echo1+2+ "3+4+5", it is treated as an expression. This involves the problem of different data type operations in PHP. Data of different data types when participating in data, PHP will convert data to try to ensure that the expression success
