  • Patent number: 10341179
    Abstract: A management computer manages first XaaS including a first node configuration and second XaaS including a second node configuration that is dependent on resources provided by the first XaaS. When a required resource amount which is required for the first XaaS in order to change the second node configuration is larger than a resource amount which can be provided by the first XaaS, the management computer determines a changed first node configuration which is capable of providing a resource amount equal to or larger than the required resource amount and, after changing the first XaaS to the determined changed first node configuration, changes the second node configuration of the second XaaS.

  • Patent number: 10333859
    Abstract: In a system, such as a cloud, which allows resource allocation to be flexibly changed in a multi-tenant environment, it is necessary to interchange resources between the tenants. Efficient resource coordination for resource allocation cannot be attained by merely adjusting resource allocation amounts or resource usage amounts. In order to address this problem, the present invention selects an optimum allocation method from among a plurality of resource allocation methods including CPU capping, taking into account each period for which resources must be allocated and the manner in which each tenant uses resources, and then coordinates allocation of resources across the entire system using the selected allocation method. This makes it possible to improve the efficiency of resource coordination even in a multi-tenant environment.

  • Patent number: 10019182
    Abstract: A management system, which manages at least a computer system including a copy destination VOL, receives first performance related information including information related to a resource related to an operation with which a copy source VOL is associated as an I/O destination, and stores the received first performance related information. When an operation migrates from a first site to a second site (for example, when the first site is affected by a disaster), the management system reallocates a resource of the second site based on both the first performance related information and second performance related information including information related to a resource related to an operation originally executed at the second site among a resource group of the second site.
