  • 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: 10275316
    Abstract: A file on file storage is archived as an object on object storage. In this case, a correspondence between UUID which is an identifier of the object and a path or an inode number which is an identifier of the file is recorded. This is referred to as correlation between the file and the object. However, because of changing of the path due to the renaming of the file, or changing of the inode number due to overwriting of the file, the correlation is likely to be lost. The invention provides a technique that restores the lost correlation and causes the correlation between the file and the object to be maintained.
