RAID is a disk subsystem consisting of multiple independent, high-performance disk drives, thereby providing higher storage performance and data redundancy technology than a single disk. RAID is a class of multi-disk management technology that provides high-performance storage with high data reliability at an affordable cost to the host environment. The two key goals of RAID are to improve data reliability and I/O performance. In a disk array, data is spread across multiple disks, but for a computer system, it is like a single disk. Redundancy is achieved by writing the same data to multiple disks at the same time (typically such as mirroring) or by writing computed check data to an array, ensuring that data loss is not caused when a single disk fails. This article uses the DELL PowerEdge T340 as an example to create a RAID1 disk array.
Review:
DELL helped me choose: RAID configuration:The hyperlink login is visible.
First, log in to the iDRAC9 web console, click Storage, and view the physical disk, as shown below:
(I inserted.)2 x 2TB hard drives）
Click Virtual Disk to create a virtual disk, as shown below:
We create a disk array in RAID1 mode, as shown in the image below:
Click Apply Now, and the task will be dropped into the background queue, as shown in the figure below:
Wait a moment for the task to be completed, as shown below:
