摘要:
This invention provides a system including a computer and a storage-subsystem comprising at least either a first storage area for storing data sent from the computer or a second storage area to be associated with the first storage area, for storing replicated data of data stored in the first storage area. This system includes a replication processing status referral unit for referring to a replication processing status of data of the first storage area and the second storage area to be associated, and an output unit for outputting first performance information concerning data I/O stored in the first storage area, and outputting second performance information concerning data I/O stored in the second storage area together with the first performance information when the replicated data is being subject to replication processing from the first storage area to the second storage area as a result of referring to the replication processing status.

摘要:
The object of the invention is to control the power consumption in a storage subsystem. In a storage system, when a monitor in a host computer acquires information concerning a storage region to manage the storage region, a monitor in the host computer checks whether or not the power supply state in the storage region is ‘on’ based on a storage region information that stores first information indicating whether or not the power supply state in the storage region is ‘on’ and second information concerning the storage region, and acquires the second information from the storage region information table if the power supply state in the storage region is not ‘on’.
摘要:
Access to the physical disks is differentiated as access from a host computer, and access based on processing (data migration processing, copy processing) for storage management. Whether to switch the state of the physical disks from a normal power consumption mode to a power saving mode is determined according to the access from the host computer after the access based on processing for storage management is complete, and the state of the physical disks are switched from the normal power consumption mode to the power saving mode based on the determination result.

摘要:
A computer system in which an encryption-decryption process performed by one encryption-decryption module can be moved to another without stopping the process for a read/write request from a host computer. The computer system has a host computer, and a storage system for storing encrypted data. The storage system provides a storage area for accepting access from the host computer. In performing a process for changing the data encrypted and stored by the destination source, the move destination encrypts the data decrypted by the move source which further encrypts and stores the data encrypted by the move destination, and after all data is stored, the move source decrypts and stores the further encrypted data.
摘要:
To provide a computer system in which an encryption-decryption process performed by one encryption-decryption module can be moved to the other encryption-decryption module without stopping the process for a read/write request from a host computer. The computer system has a host computer 200, and a storage system 400, 500 for storing the encrypted data in a storage area. The storage system 400 provides a storage area of the storage system 500 as the storage area of its own for accepting access from the host computer 200. In performing a process for changing for the data encrypted and stored by the destination source 500, the move destination 400 encrypts the data decrypted by the move source 500, the move source 500 further encrypts and stores the data encrypted by the move destination 400 in the move source 500, and after all the data is stored, the move source 500 decrypts and stores the further encrypted data in the block.
