Disk usage

The disk usage Monitor allows you to identify when the workload of the server becomes too intensive for the current disk I/O capabilities. This is a critical issue for database management systems, that use MySQL. Response times of a MySQL server can decrease greatly if disk I/O becomes a bottleneck. You must ensure that data is distributed over multiple disks in such a way that their usage is low and can handle sudden bursts of activity. You can also configure disk striping, which divides data into blocks and automatically spreads those blocks over multiple disks.
