Even in such a case, however, the contents can be used safely.
Detection of bottlenecks where I/O is concentrated is supported by monitoring disk loads at fixed intervals and displaying collected load information on a client screen.
Load balancing is possible for bottleneck logical disks on heavily loaded physical disks by dynamically reallocating the load even when the logical disks are in operation. Therefore, disk performance can be improved without interrupting business.
Since load status after planned reallocation are predicted and displayed on the client screen before logical disks are actually reallocated, confirming the effect of the reallocation operation is possible.
