摘要:
A control device of a storage system including a CPU which receives input information including at least a size and an archive deadline of data which is stored in storage devices; wherein data management information includes a write threshold value regarding one type of storage devices, the write threshold value indicating a write limit number to the one type of storage devices, wherein the CPU: selects a storage device which stores data corresponding to the information which is input to an input device, based on the information which is input to the input device and the data management information which is stored in the memory; CPU stores to the selected storage device, the data corresponding to the information which is input to the input device; and, registers to the data management information in the memory, at least one of the information which is input to the input device.

Provided are a backup data management system and a backup data management method capable of facilitating the management of backup data that is multiplexed between different storage apparatuses. The backup data management system includes a storage apparatus having a volume to be used by a host computer, at least one storage apparatus having volumes, and a management computer. The management computer creates a copy pair so that a snapshot of the volume included in a backup group is stored in all the volumes included in the backup group, and sets all copy pairs included in the designated backup group to a PAIR status when there is a creation request of the snapshot of the volume.
摘要:
There is provided a data migrating method including the steps of: calculating, in a case where data stored in a volume is migrated to another volume, a required period of time for migrating the data based on a size of data to be migrated and volume configuration information on the volume in which the migrated data is stored and the volume to which the data is to be migrated; determining a start time at which the data migration starts to generate a volume migration plan; setting a priority of the generated volume migration plan; prioritizing, in a case where a periods of time during which the generated volume migration plan is executed and a period of time during which an existing volume migration plan is executed are overlapped with each other, and changing the start time of at least one of those volume migration plans having a lower priority.

This management computer for managing a plurality of storage apparatuses having a volume storing data sent from a host computer has a schedule information acquisition unit for acquiring schedule information as a schedule of a time frame in which the host computer accesses the volume of the plurality of storage apparatuses, and a power supply control command unit for sending to a corresponding storage apparatus a power supply control command for turning off a main power supply of the storage apparatus of a time frame in which the volume is not accessed based on a referral result of the schedule information acquired with the schedule acquisition unit.
摘要:
Provided is a computer system including a first storage subsystem and a second storage subsystem. The first storage subsystem has a first storage unit and a first control unit. The second storage subsystem has a second storage unit and a second control unit. The first control unit records journals, and identifies, when data stored in the first storage unit is to be migrated to the second storage unit, which ones of the recorded journals are related to the data that is to be migrated. The first control unit chooses the identified journals one at a time in reverse chronological order, and judges whether or not the chosen journal corresponds to a data update made at some point between a current time and a time that precedes the current time by a length of a journal retention term set for the second storage subsystem.
摘要:
There is provided a computer system comprising a first storage system and a second storage system coupled to the first storage system. The first storage system provides a first storage area. The second storage system provides a second storage area. The second storage system reads and writes the requested data from and to the first storage area associated with the second storage area; specifies the first storage area associated with the second storage area from which the data is to be erased upon reception of a request for erasing the data stored in the second storage area; and transmits the request for erasing the data to the first storage system providing the specified first storage area. The first storage system erases the data stored in the specified first storage area, based on a data erasure condition included in the request for erasing the data.
摘要:
A storage system comprises a first storage apparatus having a volume for a host computer, a second storage apparatus connected to the first storage apparatus, and having a volume having a pair relationship with a first volume in the first storage apparatus, and a management apparatus connected to the first storage apparatus and the second storage apparatus. The management apparatus includes a user interface for setting an attribute of a function related to the volume of the first storage apparatus and an attribute of a function related to the volume of the second storage apparatus. The management apparatus compares the attribute of the function related to the first volume and the attribute of the function related to the second volume, and outputs the result of the comparison to the user interface.
摘要:
A first storage system specifies a journal to be transferred in accordance with a time period for retaining write data in update (write) units of data in a second storage system, and transfers this journal to the second storage system. Data for which the retention period has expired is transferred by selecting write data by address.
摘要:
A computer specifies the configuration of a first storage device by referencing first configuration information relating to the configuration of a first storage system including the first storage devices, specifies one or more storage medium access performances corresponding to the first storage device by referencing the storage medium performance information, and calculates a first access performance index of the first storage device based on one or more specified storage medium access performances. The computer then references storage medium performance information and second configuration information relating to the configuration of a second storage system including a second storage device, and determines a second storage device having an access performance index that is at least equal to the calculated first storage access performance index.
