Abstract: If a failure occurs in physical resources constituting a virtual volume, a management server device is notified of information required by a user. A computer system includes a server device for managing a plurality of virtual volumes, a storage apparatus having a storage unit equipped with a plurality of storage devices, and a controller for controlling data input to, or output from, the storage unit, a management server device which is an access target of a user terminal, and an event management device for managing an event(s) generated by the server device or the storage apparatus, wherein when the event management device receives the event, it judges the content of the event and identifies a virtual volume to be affected by the event; and if a service level that should be satisfied by the identified virtual volume is defined for the identified virtual volume, the event management device identifies, based on the content of the received event, whether an incident in violation of the service level has occurred or not, and then notifies the management server device of the identified content as an event based on an event filter.

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.

Abstract: The present invention is provided to suppress input and output requests to a storage apparatus when a plurality of cloned files has been created based on one shared file. A storage system comprises a plurality of clone-use cache areas 304 corresponding to the cloned files, and a shared cache area 305 corresponding to a shared file. When a read request for any of the cloned files has been received, a prescribed clone-use cache area, from among the plurality of clone-use cache areas, that corresponds to the read-target cloned file is searched for the read-target data, and when determination is made that the read-target data does not exist in the prescribed clone-use cache area, the shared cache area 305 is searched for the read-target data.

Abstract: A digital twin management system manages a virtual model that represents an actual physical system in a virtual space on a real-time basis. To generate an integrated virtual model by adding a second virtual model to a first virtual model, a processor of the digital twin system extracts multiple parts that can be used in common in the first virtual model and the second virtual model, generates multiple integrated virtual models that are candidates of an integrated virtual model by changing the extracted parts that can be used in common, calculates an evaluation of each of the generated integrated virtual models, and outputs configuration information regarding each of the integrated virtual model candidates and an evaluation of the integrated virtual model candidate in association with each other.

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.

Abstract translation: 文件存储上的文件作为对象存储在对象上。 在这种情况下，记录作为对象的标识符的UUID与作为文件的标识符的路径或者inode号之间的对应关系。 这被称为文件和对象之间的相关性。 然而，由于由于文件的重命名而改变了路径，或者由于文件的重写而改变了inode号，所以相关性可能会丢失。 本发明提供一种恢复丢失的相关性并导致文件和对象之间的相关性被维持的技术。

Abstract: A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

Abstract: A first storage apparatus determines whether to execute bulk requesting of causing a second storage apparatus to group a plurality of actual files corresponding to a plurality of stub files into one bulk data and transmit the bulk data. When determining to execute the bulk requesting in the determination, the first storage apparatus transmits a bulk request to the second storage apparatus. The second storage apparatus that has received the bulk request groups a plurality of actual files into one bulk data based on the bulk request, and transmits the bulk request to the first storage apparatus. The first storage apparatus that has received the bulk data extracts the plurality of actual files corresponding to a plurality of stub files, from the bulk data.
