Abstract: A conversion unit acquires collected information from a plurality of customer servers and performs a plurality of conversions different with respect to each of the customer server on the acquired collected information to generate conversion data. An identification unit performs identification on information contained in each set of collected information in a state where, with respect to the conversion data generated by the conversion unit, information before the conversion performed by the conversion unit is secreted.

Abstract: A system-replication control apparatus includes a processor that executes a process. The process includes: monitoring a use state of a resource in each of data centers; storing facility information indicating resources respectively held by the data centers and a use cost of the resources, and replication condition applied when each system is replicated in a resource of another data center; and selecting a resource composition that satisfies the replication condition and that costs lower than a currently-selected resource, as a replication destination of the system, from among available resources by referring to the use state of the resource obtained at the monitoring and the facility information.

Abstract: A method includes: receiving a reservation, made by a user from a user terminal, regarding a bandwidth of a line; first determining whether or not a total bandwidth of a bandwidth demanded by the reservation in a time slot related to the received reservation and a guaranteed bandwidth to one or more reserved users exceeds a permissible upper limit value of the line; when the total bandwidth exceeds the permissible upper limit value, calculating a reducible bandwidth based on a bandwidth shortage produced by subtracting the permissible upper limit value from the total bandwidth and statistical information of a use bandwidth consumed by the one or more reserved users; second determining a reduction bandwidth reduced from the guaranteed bandwidth based on the calculated reducible bandwidth; and assigning, by a processor, the determined reduction bandwidth to the bandwidth demanded by the reservation.

Abstract: A control server includes a memory that stores therein configuration information on a system that operates in each of data centers. The control server specifies, from the information stored in the memory, a data center having configuration information on the system that meets a condition under which a failure occurs. Thereafter, the control server transmits failure information relating to the failure to a notification destination of the specified data center that meets the condition under which a failure occurs.

Abstract: A calculation unit calculates a priority for investigating each of a plurality of services operated by a first system and a second system that is a cluster configuration and is divided into a plurality of nodes in a plurality of data center, when the services are handed over from the first system to the second system, based on a degree of influence on a client device that uses the services and a degree of importance of each of the services. An output unit outputs the calculated priority.

Abstract: A failure management server stores therein a plurality of failure cases in which the content of failure handling performed in the past in order to handle a failure is associated with the level of a contact person who is in charge of the failure handling. The failure management server stores therein a plurality of pieces of contact person information which are related to each of the contact persons which include level information that indicates the level attached to each of the contact persons. Then, the failure management server acquires, from the level information, the level of the contact person who is in charge of the failure handling that is requested for a search, extracts a failure case on the basis of the acquired level of the contact person, and outputs the extracted failure case as a search result.

Abstract: An abstraction unit converts confidential information to alternative information. An association information management unit manages association information that indicates association of the alternative information and the confidential information. A process control unit processes by using the data obtained by converting the confidential information to the alternative information. An investigation information management unit creates investigation information that indicates the operation of a storage device, by using the alternative information and collects the investigation information related to a trouble that has occurred in the storage device from among the pieces of the investigation information. A management server allows, in response to a request from an investigator terminal, the investigation information management unit to collect the investigation information related to the trouble.
