摘要： In a storage system, when power supply to HDDs is instantaneously interrupted, a spin up controller of a magnetic disk apparatus spins up the HDDs. On the other hand, based on a response for an access to the HDDs in the magnetic disk apparatus, when detecting that the HDDs as an access destination are spun down, a spin up controller of a control apparatus spins up the HDDs. When a certain number of the HDDs or more are spun down, a separate controller does not permit the magnetic disk apparatus to be used for a given length of time. While the magnetic disk apparatus is not permitted to be used, the HDDs are spun up by using the spin up controller of the magnetic disk apparatus.

摘要： In a storage system, when a recovered error occurred upon access to a storage apparatus, a data redundancy determination unit determines whether data to be accessed has redundancy. When the data is determined to have no redundancy, an anomaly-occurring portion determination unit determines that the storage apparatus is not an anomaly-occurring portion and at the same time, an error history determination unit determines whether a recovered error occurred at the time of the past access to the storage apparatus other than that of the access destination. The anomaly-occurring portion determination unit determines whether a common transmission path is the anomaly-occurring portion based on the determination result of the error history determination unit.

摘要： A storage device includes a plurality of data storage units that store data; an attribution storage unit that stores an attribution group including each data storage unit on the basis of attributions of the plurality of data storage units; a defect storage unit that stores defects that occurred in a data storage unit; and a preventive-maintenance-subject extracting unit that extracts, as a preventive-maintenance subject, another data storage unit belonging to the same attribution group as the data storage unit in which the defects stored by the defect storage unit has occurred, on the basis of an occurrence history of the defects that occurred in the data storage unit and the attribution group stored by the attribution group storage unit. The storage device also includes a preventive-maintenance performing unit that performs preventive-maintenance on data stored in the other data storage unit extracted by the preventive-maintenance-subject extracting unit.

摘要： A code conversion apparatus, a disk drive, a code buffer, and an encryption buffer are included in a storage. The code buffer stores therein first encrypted data present in the disk drive, and the encryption buffer stores therein first unencrypted data present in the disk drive. An encrypting unit encrypts the first unencrypted data present in the encryption buffer to predetermined encrypted data, and a decrypting unit decrypts the first encrypted data present in the code buffer to second unencrypted data. Moreover, a re-encrypting unit decrypts the first encrypted data present in the code buffer to third unencrypted data and encrypts the third unencrypted data to second encrypted data different from the first encrypted data.

摘要： A storage system includes a storage and control units. In each of the control units: a relay unit relays access to the storage; an access controller accesses the storage through one of the relay unit in the control unit and the relay unit in another of the control units; and an operational-state controller determines whether or not the relay unit in the above-mentioned another control unit is usable when the operational-state controller detects occurrence of an abnormality in the above-mentioned another control unit, and makes the above-mentioned another control unit transition to a partially-operational state when the relay unit in the above-mentioned another control unit is usable. In the partially-operational state, at least the access controller in the above-mentioned another control unit is not in operation and the access controller in the control unit can access the storage through the relay unit in the above-mentioned another control unit.

摘要： In a storage system, when power supply to HDDs is instantaneously interrupted, a spin up controller of a magnetic disk apparatus spins up the HDDs. On the other hand, based on a response for an access to the HDDs in the magnetic disk apparatus, when detecting that the HDDs as an access destination are spun down, a spin up controller of a control apparatus spins up the HDDs. When a certain number of the HDDs or more are spun down, a separate controller does not permit the magnetic disk apparatus to be used for a given length of time. While the magnetic disk apparatus is not permitted to be used, the HDDs are spun up by using the spin up controller of the magnetic disk apparatus.
