  • Publication number: 20150363128
    Abstract: A management system manages at least a storage system. The management system decides two or more logical storage devices configuring a logical volume to be provided to an application. The management system decides two or more MPs that undertake processes on the two or more logical storage devices, respectively. The management system allocates the decided two or more MPs to the decided two or more logical storage devices such that one MP is allocated to one logical storage device.

  • Publication number: 20150301745
    Abstract: In a computer, a logical partition for calculation in which an OS and an application operate and a logical partition for storage for providing a storage function are constructed. In the logical partition for calculation, a device corresponding to a storage device is provided, while the logical partition for storage provides a volume. A memory space that can be shared by the both logical partitions is prepared, and management information describing a sorting destination or a sorting method of an I/O request issued by an application is provided in the memory. If the logical partition for calculation receives an I/O request from the application, the partition refers to the management information and sorts the I/O request to the storage device or the logical partition for storage. The logical partition for storage processes the received I/O request by the storage function and transmits the result to the storage device.

  • Publication number: 20150161051
    Abstract: A plurality of nodes includes an I/O (Input/Output) node and a plurality of computation nodes. Each computation node sends an I/O request to the I/O node. The I/O node includes a first storage device which stores data to be written or read according to the I/O request and a first memory device on which a first cache area is based to temporarily store the data written in the first storage device or read from the first storage device. The computation node includes a second memory device on which the second cache area is based to temporarily store the data according to the I/O request. At least one of the I/O node and the computation node stores management information which contains information on a physical storage area in the cache area of the other one of the I/O node and the computation node, and information on a virtual storage area which is associated with the physical storage area and has a part of its own cache area.

  • Patent number: 9047195
    Abstract: At least one of a first application program and a second application program sends an access request to a second cache management module, which receives the access request, and references the second cache management table to identify the storage location of the access-target data conforming to the access request. When access-target data exists in first cache area, the second cache management module sends a request to the first cache management module storing the access-target data, and where access-target data does not exist in the first cache area, acquires the access-target data from the second storage device. When the access-target data is in first cache area, the first cache management module acquires the access-target data conforming to the request from the relevant first cache area, and sends access-target data to the second cache management module.

  • Publication number: 20140012936
    Abstract: The first application program and/or the second application program send(s) an access request to the second cache management module. The second cache management module receives the access request from the first application program and/or the second application program, and references the second cache management table to identify the storage location of the access-target data conforming to the access request. When access-target data exists in first cache area, the second cache management module sends a data transfer request to the first cache management module storing the access-target data, and where access-target data does not exist in the first cache area, acquires the access-target data from the second storage device. When the access-target data is in first cache area, the first cache management module acquires the access-target data conforming to the data transfer request from the relevant first cache area, and sends access-target data to the second cache management module.

  • Publication number: 20090259737
    Abstract: Reconfiguration plans that cope with various events are produced for a computer system. An administration system for computers and an administration method for computers in accordance with the present invention have a constitution described below. A server system includes plural servers, and a management server that administers the server system is connected to the server system. The management server monitors an event occurring in the server system, produces reconfiguration plans for the server system on the basis of priorities assigned to the plural servers and/or application programs according to the monitored event, selects a reconfiguration plan from the reconfiguration plans under predetermined criteria for selection, and reconfigures the server system according to the selected reconfiguration plan.
