Management apparatus and method to prevent a drop in the service quality of data. In a computer system which replicates and holds data which is stored in a storage apparatus by a communication terminal in other storage apparatuses, physical position information of the storage apparatuses and the communication terminal is collected and, at the time of the disaster recovery processing, a storage apparatus for which the data of the secondary system is to be switched to the primary system is selected from among the storage apparatuses which hold the data of the secondary system on the basis of physical position information in a first predetermined period among the collected physical position information of the communication terminal, and a policy preconfigured for the data, and an instruction is issued to the selected storage apparatus to switch the data of the secondary system held by the storage apparatus to the primary system. |

1. A management apparatus for managing a computer system which comprises a plurality of storage apparatuses and which replicates and holds data which is stored by a communication terminal in the storage apparatuses, in one or more of the other storage apparatuses, the management apparatus comprising:
an information collection portion configured to collect physical position information of the plurality of storage apparatuses and the communication terminal, a disaster recovery controller configured to monitor the existence of faults in the storage apparatuses which hold data of a primary system and, upon detecting a fault in the storage apparatuses, issue an instruction to a storage apparatus which holds data of a secondary system which is a replication of the data of the primary system to execute disaster recovery processing to switch the data of the secondary system to the primary system; and a location optimization portion configured to execute location optimization processing which verifies, at regular intervals, whether the location of the data executed by the disaster recovery processing is optimal, and which issues an instruction to the corresponding storage apparatus to switch between the primary system and secondary system of the data as necessary, wherein: at the time of the disaster recovery processing, the disaster recovery controller is configured to select the storage apparatus for which the data of the secondary system is to be switched to the primary system from among the storage apparatuses which hold the data of the secondary system on the basis of physical position information in a first predetermined period among the physical position information of the communication terminal collected by the information collection portion, and a policy which has been preconfigured for the data, and issue an instruction to the selected storage apparatus to switch the data of the secondary system held by the selected storage apparatus to the primary system, and at the time of the location optimization processing, the location optimization portion is configured to select the storage apparatus for which the data of the secondary system is to be switched to the primary system from among the storage apparatuses which hold the data of the secondary system on the basis of physical position information in a second predetermined period among the physical position information of the communication terminal collected by the information collection portion, and a policy which has been preconfigured for each of the data, issue an instruction to the selected storage apparatus to switch the data of the secondary system held by the selected storage apparatus to the primary system, and issue an instruction to a particular storage apparatus which holds the data of the primary system to switch the data of the primary system held by the particular storage apparatus to the secondary system. |
