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: 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: A contact module includes a dielectric holder holding signal contacts and guard traces. The guard traces are electrically commoned and provide electrical shielding between the corresponding signal contacts. A ground shield is coupled to a first side of the dielectric holder and provides electrical shielding for the signal contacts. The ground shield is electrically connected to each guard trace and has a plurality of rails. Each rail has side strips aligned with the signal contacts and connecting strips extending inward from a first edge of the side strip into the dielectric holder to directly engage the corresponding guard traces. The rails are generally L-shaped defined by the side strips and corresponding connecting strips.
