20100077162 | METHOD OF CONSTRUCTING REPLICATION ENVIRONMENT AND STORAGE SYSTEM - A management computer collects a usage condition of a volume from a host computer and a storage apparatus at each site, consolidates management thereof, and prevents a volume from duplicating among applications as a copy source. This makes it possible to select a used volume in an application as a copy source without excess or deficiency and to create a copy pair configuration definition without duplication or incompatibility. If a replication environment is constructed in a large-scale storage system, the consolidated management of a usage condition of a volume collected from the host computer and the storage apparatus at each site makes it possible to create a copy pair configuration definition by a task constituted by a plurality of applications. | 03-25-2010 |
20100209041 | PHOTOELECTRIC COMPOSITE WIRING MODULE AND METHOD FOR MANUFACTURING THE SAME - A photoelectric composite wiring module includes a circuit substrate, an optical device, an LSI having a driver and an amplifier for the optical device, and a thin film wiring layer having an electrical wiring. The optical device is connected with the LSI by means of the electrical wiring. The optical device is formed on the circuit substrate and optically coupled to an optical waveguide formed in the circuit substrate. The thin film wiring layer is formed on the optical device to ensure that the optical device is electrically connected with the electrical wiring of the thin film wiring layer. The LSI is mounted on and electrically connected with the thin film wiring layer. | 08-19-2010 |
20100328815 | MAGNETIC DISK DEVICE - Due to a difference in coefficient of linear expansion between the constituent material of the flange and the constituent material of the base of the feedthrough, the solder material which joins these materials is unable to withstand the thermomechanical loading that is generated between these heterogeneous materials during their actual usage for a long period and, as a result, cracks formed in the solder-joined portion therebetween create low-density gas leakage paths that reduce actual lifespan to less than 5 years. Disclosed is a magnetic disk device comprising a magnetic disk, a magnetic head for recording and reproducing information onto and from the magnetic disk, a base, a feedthrough solder-joined to the base, and a solder-joined portion for joining the base and the feedthrough, wherein a recess portion is provided in the perimeter edge of the solder-joined portion of the base. | 12-30-2010 |
20110060878 | MANAGEMENT COMPUTER - The management computer allocates a volume of an external storage device to a host so as to satisfy performance requirements specified from the host. The management computer selects a path that is formed including a first port of the storage device and a second port of the external storage device and that satisfies the performance requirements from the host, and then sets the priority. The management computer sets to the host the use authorization of a primary port and a secondary port that constitute a selected path and the use authorization of a second logical volume. | 03-10-2011 |
20110179188 | STORAGE SYSTEM AND STORAGE SYSTEM COMMUNICATION PATH MANAGEMENT METHOD - The present invention makes it possible to reassess respective host paths and reset priorities in accordance with the current state of a storage system. A management computer | 07-21-2011 |
20110219271 | COMPUTER SYSTEM AND CONTROL METHOD OF THE SAME - A computer system functions to dynamically assign the storage capacity to the host computer. If an event such as a failure occurs in the logical resources, the performance requirements of the virtual volumes must be guaranteed to the host computer. | 09-08-2011 |
