To selectively use cost, performance, reliability, and security characteristics of storage devices in an appropriate manner. A storage system has a plurality of volumes of which reliability and security levels differ from one another, and a controller of the storage system determines a reliability requirement and a security requirement of a file based on at least one of a type and a content of the file, determines a volume to store the file based on the determination result, and stores the file in the determined volume.

Storage system and file arrangement method of storage system

A management system manages an infrastructure system configured to provide a resource for operating a business system and included a plurality of infrastructures with different architecture. The management system comprises a monitoring module configured to monitor a usage state of the resource of the business system; and an analysis module configured to identify a business system being a migration target. The analysis module is configured to: analyze a usage tendency of the resource of the business system, determine which of the infrastructures is appropriate for the business system, and store a result of determining as a first determination result; identify a target infrastructure, which is an infrastructure for which the resource is predicted to become insufficient; select a business system being the migration target from among business systems operating on the target infrastructure based on the first determination result; and migrate the selected business system.

Management system and management method for migrating a business system operating on a target infrastructure

The deterioration of the operational efficiency of an optimal object placement device caused by the degradation in the access speed to the objects is inhibited. An optimal object placement device optimizes, in an information processing system having a storage area in each of a plurality of sites and in which a user can access objects stored in the storage area of all of the sites from each of the sites, placement of each of the objects; and an optimal object placement method is executed by the optimal object placement device, wherein control is executed for detecting an access tendency of the user's access to the objects.

Optimal object placement device and method

A storage apparatus includes a plurality of resources including a plurality of types of surplus resources, determines a surplus resource introduction plan used for coping with abnormalities, and controls allocation of the surplus resources according to the determined introduction plan. The storage apparatus includes a processor. The processor detects an abnormality associated with the resource of the storage apparatus, calculates one or more surplus resource introduction plans capable of coping with the abnormality on the basis of management information of the resource of the storage apparatus when the abnormality is detected, and determines, when there are a plurality of introduction plans, an introduction plan used for coping with the abnormality on the basis of a state in which other abnormalities that are likely to occur concurrently with the abnormality can be coped with, by surplus resources remaining when the introduction plans are executed.
