PC Skills Classroom Disk Array Formation and Maintenance

"Disk array" is RAID, which combines multiple independent hard disks (physical hard disks) in different ways to form a disk group (logical hard disk), which provides higher storage performance and data than a single hard disk. Backup technology. Commonly used are RAID0, RAID1, RAID0+1 (also called RAID10), RAID5, and so on. With the recent decline in hard drive prices and the increasing popularity of RAID functions on medium and high-end motherboards, many friends have begun to build their own RAID systems. However, due to the great difference between the RAID system and the single hard disk, many newcomers will encounter various troubles during the formation process. Let's take the High Point 374 array card as an example to introduce the establishment and maintenance of RAID5 (the setting method of other manufacturers' products may be different, this post is for reference only, don't make a hard copy!)

After the array card and hard disk are properly installed, the system will automatically go to the self-test screen of the RAID card after the motherboard self-test completes. Press Ctrl+H to enter the array card BIOS setting interface (other RAID cards enter the BIOS shortcut key). It may be different. Please refer to the manual for details.

Second, the main interface of the array card BIOS
The air disk model and the disk capacity information are empty when the array is not established:
< Br>

If an array has been created, display array related information between hard disk model and disk capacity information

Third, create a new RAID5 array:
1 Select in the array card BIOS menu Create and select RAID5 from the drop-down menu

2Edit Array Name

3Select the disk to form the array

4 Start the initialization of the disk array (initialization is similar to low-level formatting of disk partitions)

Attention! ! If you select No Build and do not initialize, you can use the disk array immediately, but the data may be wrong or lost.
