摘要： A data processing device has plural kinds of recording media and a data block management device. The data block management device classifies data blocks into plural groups and records each group on an appropriate recording medium. The data block management device has a memory unit, a group reconfiguration unit and a medium selection unit. Access trend information representing a trend of combinations of former groups and latter groups is stored in the memory unit. The group reconfiguration unit performs group reconfiguration processing by reference to the access trend information. Specifically, if a sequential access trend between two different groups is increased, they are integrated to generate a new group. If a sequential access trend within a certain group is decreased, the certain group is divided to generate a new group. The medium selection unit records the new group obtained as a result of the group reconfiguration on a corresponding recording medium.

摘要： A technique for supporting the sizing of hierarchical computer resources is provided. The sizing support system includes a memory, a table definition module and field calculation module. The memory stores lower level resource data which indicates the kinds and the maximum number of lower level resources belonging to the resources of each hierarchy level, and resource data which indicates parameters of resources of each hierarchy level. The processing is executed in a unit of three levels. In the unit process of three levels, the table definition module generates a table frame indicating the possible configurations of first resource by referring the lower level resource data. The field calculation module calculates the performance and cost of the configuration in the table frame by referring the resource data.
