Abstract:
A processor of a storage controller receives an erasure process request relating to data stored in a storage unit, from a host computer, via a data I/O interface, detects a logical storage extent which is different to the logical storage extent allocated to the storage unit and which can be allocated, allocates the logical storage extent thus detected to the storage unit, sends a notification indicating that access to the storage unit is possible, to the host computer which is the source of the request, and then executes erasure of the data in the logical storage extent that is associated with the storage unit forming the erasure object, and sends a data erasure notification to the management computer when the data has been erased.
Abstract:
A probe card is disclosed that includes a board having a first surface and a second surface facing away from each other and a through hole formed between the first and second surfaces; and a probe needle having a penetration part and a support part. The penetration part is placed in the through hole without contacting the board and projects from the first and second surfaces of the board. The support part is integrated with a first one of the end portions of the penetration part and connected to one of the first and second surfaces of the board. The support part has a spring characteristic. The penetration part is configured to have a second one of its end portions come into contact with an electrode pad of a semiconductor chip at the time of conducting an electrical test on the semiconductor chip.
Abstract:
A light-emitting device including a light-emitting element and a substrate where the light-emitting element is arranged. A housing part housing the light-emitting element and having a shape that is tapered upward from the substrate and a metal frame surrounding the light-emitting element and including the side face of the housing part made into an almost mirror-polished surface are provided on the substrate.
Abstract:
The threshold excess is judged by a peak value, and therefore, since the threshold excess is judged by a value of high-workload IO of backup or the like that is designed on the assumption that the workload of storage is high, whether the performance limit has been reached remains uncertain. Furthermore, although an optimistic prediction trend with low workload trend and a pessimistic prediction trend with high pessimistic workload trend are presented, LUs that require improvement remain uncertain. Moreover, the time to improve the configuration and the effect of the improvement remain uncertain, and therefore, an improved configuration cannot be determined.Configuration information, performance information, and operation information are acquired from a storage, a performance limit excess time is predicted based on the performance information excluding LUs exceeding the performance trend, and an optimal improved configuration is determined from the performance limit after improvement and the time required for the improvement.
Abstract:
A package for electronic component comprises a rectangular package body having a flat cut surface to be abutted on a flat mounting surface of a mounting substrate, a first side surface intersecting with the flat cut surface, and a first notch part formed at a boundary between the flat cut surface and the first side surface, an electronic component installed in the package body, and a first pad electrically connected to the electronic component and formed on an inner wall surface of the first notch part.
Abstract:
A computer system for preventing data loss that includes: a first storage system having a data storage extent for storing data sent from a host computer; a second storage system having at least one actual replicated data storage extent associated with the data storage extent; an archive appliance having a storage medium associated with the replicated data storage extent in the second storage system; and a data copy unit for controlling copy processing for reading data from the data storage extent in the first storage system and writing the read data to a first actual replicated data storage extent in the second storage system in accordance with specific configuration information. The system also has a connection switching unit for changing the specific configuration information so that a second actual replicated data storage extent, instead of the first actual replicated data storage extent, is associated with the data storage extent.
Abstract:
A light emitting diode includes an LED element, a fluorescent material provided so as to cover the LED element, a substrate on which the LED element is mounted and made of ceramics or silicon, and a pair of electrode pads which are electrically connected to the LED element on the substrate.
Abstract:
The control device acquires the archive deadline of archive target data and acquires, for storage devices of a plurality of types, a warranty deadline for the quality of data stored by the storage device and the unit cost which is the cost for each predetermined storage size of the storage device. The storage control device is a storage device which acquires a data migration cost and which obtains a storage destination for the archive target data from storage devices of a plurality of types on the basis of the archive deadline, warranty deadline, unit cost and data migration cost thus acquired. The storage control device selects a storage device for which the total cost is minimum when the archive target data is archived until the archive deadline.
Abstract:
A management computer includes a configuration information acquisition module that acquires a data volume configuration table indicative of a logical connection relationship between structural elements of the data storage apparatus from the data storage apparatus, a transmission path specification module that specifies the structural elements that exist on a transmission path of data which is required to be written by a host computer from the structural elements of the data storage apparatus on the basis of data volume configuration table that is acquired by the configuration information acquisition module, a performance data acquisition module that acquires the performance data of the structural elements that are specified by the transmission path specification module, and a screen transition control module that output the performance data that is acquired by the performance data acquisition module.
Abstract:
A heterogeneous network includes network related hardware and software products from a plurality of vendors. The network includes a storage system configured to store data, a server configured to process requests, a switch coupling the storage system and the server for data communication, and a network manager including an event dictionary to interpret an event message received from a device experiencing failure.
