  • Patent number: 9760294
    Abstract: A management computer stores, in a memory, virtual logical volume management information showing information on virtual logical volumes provided to a host computer by a storage device, and pool management information showing information related to a use status of pools. The management computer acquires performance information related to an access to the storage device from the host computer, determines whether the acquired performance related to the access satisfies a predetermined first required performance, or not, and specifies any virtual logical volume which is a cause of the state based on the virtual logical volume management information if the first required performance is not satisfied. The management computer calculates a capacity consumption trend of the real area included in each pool based on the pool management information, creates a countermeasure for satisfying the first required performance implementable after a given time, and outputs the countermeasure to an output device.

  • Patent number: 9671966
    Abstract: The management computer includes a memory and a processor. The processor recognizes a state of a storage system that provides a first volume as a logical volume that stores a first image of an object. The processor generates a second volume as a virtual logical volume that stores a second image of the object. The processor selects, based on the state, one generation processing from a plurality of generation processing including: first generation processing of associating the second volume with the first image and differential data from the first image to provide the second volume; and second generation processing of generating the second volume as a logical volume and copying the first image to the second volume to provide the second volume. The processor transmits an instruction to execute the selected generation processing to the storage system.

  • Patent number: 9639435
    Abstract: A management computer stores an operation requirement of a virtual machine and a scheme of a first configuration change executed by a host computer or a storage apparatus. The management computer determines whether a second configuration change configured so as to be executed automatically in the host computer or the storage apparatus is executed. If it is determined that the second configuration change is executed, the management computer predicts a performance index value concerning a prescribed performance index for the computer or the storage apparatus when executing the second configuration change. The management computer determines whether an anticipated effect value of the configuration change scheme is satisfied based on the predicted performance index value, and creates a substitution plan satisfying both an operation requirement and an anticipated effect value of the virtual machine where it is determined that the anticipated effect value is not satisfied.

  • Patent number: 9442765
    Abstract: An exemplary management system identifies, based on first information indicating a job net defining an execution order of jobs executed by the host computer, jobs having possibility to be executed simultaneously at the job net. The management system identifies, based on second information indicating an execution content of each of the jobs, storage areas at the host computer for storing data of the jobs having possibility to be executed simultaneously. The management system identifies, based on third information indicating an allocation relation between the data storage areas of the host computer and resources of the storage apparatus, a resource of the storage apparatus allocated to each of the identified storage areas. The management system determines a physical resource of the storage apparatus, allocated to at least two of the storage areas of the identified storage areas, has possibility to be used simultaneously by at least two jobs.

  • Patent number: 9395928
    Abstract: A management system is coupled to a storage system group including a scale-out storage system (a virtual storage system). The management system has storage management information, which includes information denoting, for each storage system, whether or not a storage system is a component of a virtual storage system. The management system, based on the storage management information, determines whether or not a first storage system is a component of a virtual storage system, and in a case where the result of this determination is affirmative, identifies, based on the storage management information, a second storage system, which is a storage system other than the virtual storage system that includes the first storage system, and allows a user to perform a specific operation only with respect to this second storage system.

  • Patent number: 9244616
    Abstract: A storage system manages a pool to which multiple VVOLs (virtual logical volumes conforming to thin provisioning) are associated, assigns a real area (RA) from any tier in an available tier pattern associated with a write-destination VVOL to a write-destination virtual area (VA), and carries out a reassignment process for migrating data inside this RA to an RA of a different tier than the tier having this RA based on the access status of the RA assigned to the VA. A management system assumes that a specified tier has been removed from the available tier pattern of a target VVOL, predicts the performance of the target VVOL and all the other VVOL associated with the pool to which the target VVOL is associated, determines whether or not there is a VVOL for which the predicted performance is lower than a required performance, and when such a VVOL does not exist, instructs the storage system to remove the specified tier from the available tier pattern of the target VVOL.
