摘要:
A storage arrangement including: a first storage system having one or more first logical storage devices and a second storage system having one or more second logical storage devices, configured to: a) determine whether two or more identical contents hash values are contained in a plurality of contents hash values of said plurality of files; and b) change an access destination of a first file corresponding to a first contents hash value from among said two or more identical contents hash values, to a position of a second file corresponding to a second contents hash value if there are said two or more identical contents hash values, c) do not migrate said first file to said second storage system, and migrate said second file to said second storage system to store in any of said one or more second logical storage devices.

A subsystem logics partitioning and managing apparatus comprises a recognition unit for recognizing logical and physical resources that constitute a subsystem a partition definition table in which the logical and physical resources in the subsystem are assigned for each user at an interface level at which a storage configuration can be referenced by a storage management program an account table in which an account is set for each user-specific partition defined in the partition definition table a receiving unit for receiving a user account transmitted from an information processing unit and checking the received user account against the account table, to recognize a partition that corresponds to the user and a unit for outputting, at a GUI level, logical resources and physical resources that are contained in the recognized partition to an output interface as a resource configuration in the subsystem.
摘要:
A storage system data duplication method for copying data of a plurality of logical volumes possessed by a first storage system to a second storage system includes the steps of: (a) copying the data of the plurality of logical volumes to the second storage system; (b) interrupting copying of the data of the plurality of logical volumes to the second storage system; (c) starting copying of data of one or more of the plurality of logical volumes to the second storage system; and starting copying of data of ones of the plurality of logical volumes other than the one or more logical volumes to the second storage system as delayed from the step (c), shortening a time taken until completion of data duplication on recreation of a group of paired logical volumes in a volume group after remote copy is temporarily stopped.

摘要:
Arrangements including a duplication determination unit that determines whether identical contents intrinsic values are contained in a plurality of contents intrinsic values; a change control unit that changes an access destination of a first file corresponding to a first contents intrinsic value from identical contents intrinsic values, to a position having stored therein a second file corresponding to a second contents intrinsic value from among these identical contents intrinsic values when there are identical contents intrinsic values; and, a migration execution unit which, when the migration execution unit migrates data stored in files stored in one or more first logical storage devices to one or more second logical storage devices, does not migrate first data of the first file to any of the one or more second logical storage devices, and migrates second data of the second file to any of the one or more second logical storage devices.
摘要:
A plurality of contents intrinsic values that are values intrinsic to respective contents of a plurality of files stored in one or more first storage devices are calculated. Whether two or more identical contents intrinsic values are contained among the plurality of contents intrinsic values is determined. When two or more identical contents intrinsic values are present, an access destination of a first file corresponding to a first contents intrinsic value from among these two or more contents intrinsic values is changed to a position having stored therein a second file corresponding to a second contents intrinsic value from among these two or more contents intrinsic values.

In order to assign logical devices efficiently to logical units, a disk control system that receives a process command for writing or reading of data from an information processing device, and performs a write or read process of data with respect to a logical device corresponding to a logical unit specified by that process command, includes means for managing logical devices, which are logical storage regions that have been set in a storage region provided by a disk drive, means for storing a correspondence between logical units, which are storage regions that have been set logically, and the logical devices, and means for assigning, when a process command has been received for a logical unit to which no logical device has been assigned, a logical device to that logical unit and performing processing with regard to that logical device.
