摘要： A method for handling a remote copy request in a distributed storage includes providing a plurality of primary volumes within a primary storage system that is coupled to a primary host via a first network, the primary storage system being coupled to a secondary storage system via a second network. A first request is selected from a plurality of requests placed in a queue based on priority information associated with the requests. A first path group is selected from one or more path groups that could be used to transmit the request. The first request is transmitted to the secondary storage system using the first path group, the secondary storage system including a plurality of secondary volumes that are paired to the plurality of primary volumes.

摘要： A storage apparatus and a method for controlling the same, and a computer program product, that can simplify the storage apparatus settings required whenever a storage apparatus is introduced or a new host system is added. With a storage apparatus configured to detect a connection from a new host system having no logical unit assigned thereto, and to assign, if any new host system is detected, a new logical unit to that new host system, it is possible to generate a logical unit and associate it with a relevant host system whenever a storage apparatus is introduced or a new host system is added, without input from a storage apparatus administrator at a management console, and thus it is possible to simplify the storage apparatus settings required whenever a storage apparatus is introduced or a new host system is added.

摘要： An apparatus, system, and method by which, if hard disk drives used within disk array systems are removed and installed in another disk array system or attempted to be accessed by another device, data in the hard disk drives cannot be accessed. In one embodiment, a disk array system sets a password onto each hard disk drive. The hard disk drives reject access from disk array systems or computer systems until a correct password is input. In alternative embodiments, hard disk drives memorize one or more World Wide Names (WWNs) of the disk array system. After memorizing a WWN, the hard disk drives allow access only from the disk array system having the same WWN as the one that the hard disk drives memorized. Thus, the hard disk drives are normally inaccessible after they are removed from a disk array system.

摘要： The present invention provides fair use of resources between users by reducing capacity necessary for storage of snapshot differential data. In a storage device system, differences between only those files meeting predetermined conditions are managed as snapshots. Furthermore, upper limits are set for capacity of pools used for each condition, and when the total volume of differential data stored under a certain condition reaches the pool capacity, further snapshots are not created under that condition.

摘要： A data storage system comprises a first platform storage system including a first network interface to communicate with a host computer, a first storage unit to provide storage volumes, a first storage controller to control the first storage unit, and a first memory to store a first control program to process an input/output (I/O) request received by the first platform storage system. A second platform storage system includes a second network to communicate with the host computer, a second storage unit to provide storage volumes, a second storage controller to control the second storage unit, and a second memory to store a second control program to process an I/O request received by the second platform storage system. An external storage system is coupled to the first and second platform storage systems, the external storage system including a third storage unit to provide storage volumes and a third storage controller to control the third storage unit. The first and second platform storage systems are configured to present the storage volumes of the external storage system to the host computer, so that the host computer can access the storage volumes of the external storage system via one of the first and second platform storage systems if the host computer is unable to access the storage volumes of the external storage system via the other platform storage system.

摘要： A system and method for data lifecycle management. In one embodiment, data is migrated from a source physical volume at a primary storage system to a target physical volume at an external storage system. The data from the source physical volume is copied to the target physical volume. When a request is received at the primary storage system from a server to access the data in the target physical volume, the server is added as an owner of the target physical volume, sent location information of the target physical volume, and allowed to access the target physical volume directly without passing through the primary storage system. The volume for migration may be determined based on not having been accessed for a specified period or having been specified by a user or an application to be migrated. Extents, objects and files may also be migrated.

摘要： A method and a system for implementing the method are disclosed relating to archival storage of information in large numbers of disk units. The reliability of the stored information is checked periodically using data verification operations whose results are saved. These results establish the veracity of the data and enable compliance with various regulatory requirements. The techniques described enable the use of low cost disk drive technology, yet provide high assurance of data veracity. In a typical system, management information storage is provided in which data entries are associated with each of the disk drives to provide information with respect to the condition of the data on that drive and its last verification. The data verification operations are performed on the data during time periods when I/O accesses are not required.
