20100115305 | Methods and Apparatus to Provision Power-Saving Storage System - A power-saving computer system comprises a plurality of storage areas provided by one or more storage systems, including at least one first storage area which is always powered on and at least one second storage area which is periodically powered on and off according to a power control schedule. The at least one first storage area provides primary and secondary volumes of a first backup set that is scheduled as always paired. For a second backup set that is scheduled as normally suspended and resynchronized according to a backup schedule, a primary volume of the second backup set is included in the at least one first storage area and a secondary volume of the second backup set is included in the at least one second storage area. The at least one second storage area is powered on during every backup time for resynchronizing the second backup set according to the backup schedule. | 05-06-2010 |
20100250878 | Storage System of Storing Golden Image of a Server or Any Physical/Virtual Machine Execution Environment - A storage system stores golden image of a server or any physical/virtual machine execution environment and associate the golden image and the storage port. The storage system also creates the copy of the golden image to the logical volume, and allocates the internal path between the storage port and the logical volume. Upon receiving an access request from the host computer via the storage port, the storage system transfers the access request between the storage port and the logical volume which stores the copy of golden image associated with the host computer. | 09-30-2010 |
20100274981 | METHOD AND SYSTEM FOR MIGRATION BETWEEN PHYSICAL AND VIRTUAL SYSTEMS - A method of migrating a computer system between a virtualized environment and a non-virtualized environment comprises configuring one or more storage volumes for a migration destination in a destination environment based on a migration request containing a backup requirement specifying one or more copy groups, each copy group including storage volumes that store data for at least one of a virtualized device and a non-virtualized device; converting and migrating data from a migration source in a source environment to the one or more configured storage volumes of the migration destination based on copy group information of the one or more copy groups, one of the source environment and the destination environment being a virtualized environment, and another of the source environment and the destination environment being a non-virtualized environment; and migrating backup unit/group information by replacing copy group information in the source environment with copy group information in the destination environment. | 10-28-2010 |

20080228841 | INFORMATION PROCESSING SYSTEM, DATA STORAGE ALLOCATION METHOD, AND MANAGEMENT APPARATUS - An information processing system includes: information processing apparatuses, each replicating data sent from a host computer according to redundancy designated by the host computer and creating copy data; a first storage system having volume(s) for storing the data and the copy data; and a management apparatus for managing the information processing apparatuses and the first storage system. The information processing system has: an acquisition unit for acquiring volume replication information indicating whether the volumes are to re replicated in volume(s) in a second storage system; a data storage allocation unit for setting, based on the volume replication information, at least one of the information processing apparatuses as an information processing apparatus for storing the data in a volume to be replicated in the second storage system volume; and a transmission unit for transmitting information concerning the information processing apparatus for storing the data to the information processing apparatuses. | 09-18-2008 |
20090013012 | JOURNAL MANAGEMENT METHOD IN CDP REMOTE CONFIGURATION - 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. | 01-08-2009 |
20090077557 | METHOD AND COMPUTER FOR SUPPORTING CONSTRUCTION OF BACKUP CONFIGURATION - For a storage system which holds backup data of a first data storage extent in one or more second data storage extents in use of a first backup method, a backup status in a first backup method in a prescribed period is acquired and a first backup performance in a first backup configuration is computed based on this backup status. Meanwhile, a second backup performance in a second backup configuration is estimated based on a prescribed assumption in a prescribed period. Information is outputted based on the computed first backup performance and the estimated second backup performance. | 03-19-2009 |
20090157768 | COMPUTER SYSTEM AND DATA LOSS PREVENTION METHOD - A primary storage system and a secondary storage system are connected via a copy network in this computer system. This computer system includes a measurement unit for measuring an update data input amount to be input into the primary update data storage area, a calculation unit for calculating a recovery point in each given period of time based on the measured update data input amount and the band of the copy network, and a comparison unit for comparing the calculated recovery point and a target recovery point to be pre-set as a target value for recovering the update data. | 06-18-2009 |

20110320754 | MANAGEMENT SYSTEM FOR STORAGE SYSTEM AND METHOD FOR MANAGING STORAGE SYSTEM - Provided is a management system for a storage system, the storage system including a first storage subsystem and a second storage subsystem each including logical storage areas for storing data to be processed by a host computer, the logical storage areas in each of the first and second storage subsystems having storage tiers associated respectively with a plurality of storage area characteristic information pieces which are information pieces characterizing the corresponding logical storage areas and which are different from each other, the management system comprising a data migration management part, wherein when the data is migrated from the first storage subsystem to the second storage subsystem, the data migration management part: acquires a configuration of the storage tiers of the logical storage areas of the first storage subsystem in which the data of a migration target is stored; compares the configuration with a configuration of the storage tiers of the logical storage areas of the second storage subsystem; and then migrates the migration target data stored in the logical storage areas of the first storage subsystem to the logical storage areas of the second storage subsystem in accordance with a result of the comparison. | 12-29-2011 |
20130311645 | MANAGEMENT SYSTEM AND MANAGEMENT METHOD - A management system outputs catalog data, which has been created based on catalog-source data comprising data showing at least an application of a relevant resource with respect to each of multiple providable resources, and which shows the respective applications of the multiple resources, and receives a selection of a resource to be provided from the multiple resources. The management system provides the selected resource as a provided resource, and determines, based on a performance threshold configured with respect to the application of the provided resource, whether or not a performance measurement value, which relates to the processing performance of a network service using the provided resource and which can be monitored by the management system, is normal. | 11-21-2013 |
