What is mirrored volume?

A mirrored volume is a fault-tolerant volume that duplicates data on two separate dynamic disks. If one physical disks fails, the data on it would be unavailable, while the other unaffected disk can be accessed by the operating system. Thus. mirrored volumes are widely used by those who require high performance and high safety of computer, such as server administrators.

However, with the quantity of important data stored on mirrored volume increasing, mirrored volumes will be running out of space. In this condition, you have to extend mirrored volume to include more data and files.
