A storage device stores data and is used by a plurality of information processors. The storage device receives prediction data which each of the plurality of information processors has predicted and transmitted, where the prediction data includes data regarding a data flow rate of each interface port with each of the plurality of information processors. The storage device calculates an access prediction value of each interface port based on the prediction data received from the plurality of information processors, and changes a setting of a process of each interface port based on the access prediction value.

Storage device and information processor

A storage control program causes a computer to execute a RAID level acquisition unit, a mapping unit, and a mapping information storage unit therein. The RAID level acquisition unit acquires RAID levels, supportable by a storage device including a plurality of storage mediums, from the storage device. The mapping unit maps the function types of a storage virtualization function in a host device accessing the storage device on the respective RAID levels acquired by the RAID level acquisition unit. The mapping information storage unit stores the correspondence relationship between the RAID levels and the function types mapped by the mapping unit as mapping information.

Dynamic allocation of virtualization function types to RAID levels

A first information processing apparatus of multiple information processing apparatuses includes a second configuration information storage section storing second configuration information; a first configuration information modification section modifying first configuration information in the storage apparatus; a notification section notifying, a second information processing apparatus, of modified part information indicating a modified part in the first configuration information; a modified part information storage section storing the modified part information from the second information processing apparatus; and an updating section updating, before modifying the first configuration information in the storage apparatus, the modified part in the second configuration information indicated by the modified part information stored in the modified part information storage section, based on the first configuration information. Thus, when modifying setting on the storage apparatus from multiple information processing apparatuses, the integrity of the configurations is maintained, and the system can be deployed and operated at lower costs.
