  • Patent number: 10908174
    Abstract: According to one embodiment, an automatic analyzing apparatus includes a reagent depository, a reagent storage unit and a probe. The reagent depository stores a first reagent vessel. The reagent storage unit is provided separately from the reagent depository and in which a second reagent vessel is placeable. The probe suctions a reagent contained in the first reagent vessel at a first position which is located above the reagent depository, suctions a reagent contained in the second reagent vessel at a second position which is located above the reagent storage unit, and discharges the reagent suctioned from the first reagent vessel or the second reagent vessel into a reaction vessel at a third position.

  • 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.

  • Patent number: 10128619
    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.

  • Patent number: 9477426
    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.

  • Publication number: 20160259783
    Abstract: Provided is a method for retaining metadata inheritance relationship in an object storage and for interpreting the relationship. A file and directory inheriting metadata of an upper-level directory allocates the UUID of an object corresponding to the inheritance source directory to metadata of an object of a CAS device corresponding to the file and directory as inheritance information. The inheritance information stored in the CAS device is interpreted in a metadata conversion apparatus (see FIG. 1).

  • Patent number: 9317519
    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.
