| 20080222374 | Computer system, management computer, storage system and volume management method - To provide a computer system in which the primary site administrator for managing all the sites can make the configuration of the authority to be granted beforehand for the administrator of each site to fill in for a part of its own authority, even during the absence such as at the time of disaster. The computer system includes one or more storage systems | 09-11-2008 |
| 20080270696 | VOLUME ASSIGNMENT MANAGEMENT DEVICE - The present invention is a management computer that determines, as the assignment source of a logical volume that is assigned in order to store predetermined data, a storage area of a RAID group including one or more disk drives among a plurality of disk drives provided in a storage system; and the CPU that executes the volume assignment module accepts a logical volume assignment request and, in cases where a logical volume assignment request is accepted, determines the RAID group which is the assignment source of the logical volume on the basis of the access trend assumed for the logical volume which is the subject of the assignment request. | 10-30-2008 |
| 20090077250 | Computer and Access Control Method in a Computer | 03-19-2009 |
| 20090164780 | VOLUME MANAGEMENT METHOD IN A STORAGE APPARATUS HAVING ENCRYPTION FEATURE - The invention provides a computer system including a storage apparatus having an encryption feature, a management computer for running a management program for managing the storage apparatus, and an application host computer, wherein when allocating a logical volume or creating a copy pair, the management program selects, from the storage apparatus, a logical volume that satisfies a security level required by an application program that uses the logical volume to allocate the logical volume or create a copy pair. | 06-25-2009 |
| 20090177895 | CONTROLLER FOR CONTROLLING LOGICAL VOLUME-RELATED SETTINGS - A controller carries out a first determination as to whether or not data to be stored in a target logical volume can be used by a plurality of access devices. The controller carries out a second determination as to whether or not the access devices comprise data encryption units respectively when the result of the first determination is affirmative. The controller controls a setting related to the target logical volume for one access device of the plurality of access devices, based on the result of the second determination. | 07-09-2009 |
| 20090265495 | ACCESS RIGHT MANAGING METHOD FOR ACCESSING MULTIPLE PROGRAMS - Provided is an access right managing method for a resource of a storage system, in which a management computer stores access right definition information of the resource, and resource correspondence information including information on a management program which manages another resource related to the resource managed by the management program. In case of which receiving an updating request of an access right of the resource, the management computer updates an access right based on the updating request of the access right, selects a management program of the resource whose access right is requested to be updated based on the resource correspondence information, transmits an updating request of an access right for a relative resource to a management computer which executes the selected management program, and in case of which the access right updating request of the related resource is received, updates the access right of the relative resource. | 10-22-2009 |
| 20100082900 | MANAGEMENT DEVICE FOR STORAGE DEVICE - The present invention provides effective use of a storage resource in a system where a storage area of a logical volume is dynamically extended and reduced. In an information processing system including a management device communicably connected to a storage device that can dynamically change a storage capacity of a virtual volume allocated to a host computer, when a used amount of a certain storage pool exceeds a threshold set in the storage pool, the management device sends to the storage device, an instruction to migrate a predetermined number of virtual volumes, sequentially selected in ascending order of capacity increasing rate, so that another storage pool different from the certain storage pool may be used as a creation source. At this time, as a migration destination, the management device uses, the storage pool having, for example, an attribute of the storage resource identical to that of the certain storage device. | 04-01-2010 |
| 20110040935 | MANAGEMENT COMPUTER FOR MANAGING STORAGE SYSTEM CAPACITY AND STORAGE SYSTEM CAPACITY MANAGEMENT METHOD - A management system, which manages a plurality of storage systems, in a case where belonging to a storage system having a first function constitutes a condition for allocating a plurality of volumes to a host device, retrieves the storage system having the first function from among the plurality of storage systems, selects one or more unallocated logical volumes included in the retrieved storage system, acquires a logical volume capacity included in the selected logical volumes and notifies an output device of the acquired capacity as the capacity allocatable to the host device. | 02-17-2011 |
