20120066680 | METHOD AND DEVICE FOR ELIMINATING PATCH DUPLICATION - A first computer is provided that executes a plurality of virtual machines (VMs), a storage device, and a second computer is provided that applies patches to OSs (operating systems) operating upon the VMs to the VMs. The storage device holds storage regions (golden images (GIs)) that store data of the OSs operating upon the VMs at certain time instants, a storage region (i.e. a storage pool) that stores patches applied to the OSs of the VMs after those certain time instants, and snapshots of the GIs. Patches applied to the OSs of the VMs accessed in the snapshots are stored in the storage pool. The second computer selects, as a GI to be a source of acquisition of snapshots, a GI to which are applied patches of a combination that can be created from patches applied to the OS of some VM, and deletes patches that are patches applied to the selected GI, and that moreover, among the patches applied to that VM, are stored in the storage pool. | 03-15-2012 |
20120222028 | VIRTUAL COMPUTER MANAGEMENT METHOD AND VIRTUAL COMPUTER MANAGEMENT SYSTEM - It is an object of the present invention to provide a technique that can comprehensively manage plural kinds of network addresses allocated to virtual computers. | 08-30-2012 |
20120246425 | STORAGE SYSTEM AND PERFORMANCE MANAGEMENT METHOD OF STORAGE SYSTEM - It is an object to use a storage region in an efficient manner and maintain a performance of a storage system. | 09-27-2012 |
20130073780 | VOLUME SHARING METHOD AND STORAGE SYSTEM USING THE SAME - Since only one golden image (GI) of a snapshot can exist and is shared among a plurality of storage apparatuses, there was a problem that migration or copy thereof deteriorates the capacity efficiency and increases the cost for managing consistency. The present invention solves the above-mentioned problem by either (1) a direct sharing method of generating a parent-child relationship of snapshots among different storage apparatuses at the time of creating differential LUs from the GI or (2) a virtual sharing method of creating virtual LUs of the GI in the respective storage apparatuses and creating differential LUs of the snapshots from the created virtual LUs, using a storage virtualization function among a plurality of storage apparatuses. | 03-21-2013 |
20130073825 | STORAGE APPARATUS, COMPUTER SYSTEM, AND DATA MIGRATION METHOD - Provided is a method of using a dynamic chunk allocation function to efficiently carry out data volume migration. A storage apparatus according to the present invention includes first and second storage units and divides a storage extent in the second storage unit into chunks to add the chunks to a chunk pool to dynamically allocate the chunks in the chunk pool to a newly created logical data volume (see FIG. | 03-21-2013 |
20130219138 | STORAGE SYSTEM, MANAGEMENT SERVER, STORAGE APPARATUS, AND DATA MANAGEMENT METHOD - A snapshot volume is migrated by using a primary volume of a migration destination storage apparatus. | 08-22-2013 |
20130254500 | STORAGE APPARATUS, COMPUTER SYSTEM, AND CONTROL METHOD FOR STORAGE APPARATUS - A storage apparatus of an embodiment of the invention including one or more storage drives for providing real storage resources and a controller for controlling the one or more storage drives and accesses from a host computer. The controller initializes real storage resources and manages the initialized real storage resources. The controller receives an instruction for allocating an initialized real storage resource to a first virtual storage resource accessed by the host computer. In response to the instruction, the controller allocates a first initialized real storage resource which has been initialized in advance prior to the instruction to the first virtual storage resource. | 09-26-2013 |
20130282887 | COMPUTER SYSTEM AND VIRTUAL SERVER MIGRATION CONTROL METHOD FOR COMPUTER SYSTEM - When migrating a virtual server between a plurality of physical servers, a pre-migration connection relationship between the virtual server and a storage area used by the virtual server is maintained after the migration of the virtual server by using a cooperative mechanism between a plurality of storage apparatuses even if the storage area used by the virtual server is migrated between the plurality of storage apparatuses. A computer system and virtual server migration control method for the computer system is described. | 10-24-2013 |
20130311739 | STORAGE APPARATUS, STORAGE SYSTEM, AND DATA MIGRATION METHOD - Provided are a storage apparatus, a storage system, and a data migration method with which, if data of a virtual disk which belongs to one pool area is migrated to another pool area, the migration time and processing load can be reduced by migrating the data while maintaining duplicate determination. | 11-21-2013 |
