In a silicon substrate for a package, a through electrode is provided with which a through hole passing through from a bottom surface of a cavity for accommodating a chip of an electronic device to a back surface of the substrate is filled. An end part of the through electrode in the bottom surface side of the cavity has a connection part to a wiring that forms an electric circuit including the chip of the electronic device. The silicon substrate for a package is characterized in that (1) a thin film wiring is included as the wiring and the connection part is reinforced by a conductor connected to the thin film wiring and/or (2) a wire bonding part is included as the wiring and the connection part is formed by wire bonding the end part of the through electrode in the bottom surface side of the cavity.

Provided is a computer system including a plurality of storage apparatuses, in which, if the storage apparatuses employ an external mapping/connection system, the plurality of storage apparatuses can efficiently use each other's storage resources. The computer system includes a plurality of storage apparatuses and a management computer for managing the storage apparatuses. The management computer determines whether or not it is possible to perform external connection between the plurality of storage apparatuses and whether or not it is possible to divert the use of a storage device in one storage apparatus to another storage apparatus, on the basis of a criteria table, and if it is possible to perform external connection between the plurality of storage apparatuses, it is carried out and, if it is not possible, the management computer diverts the use of a storage device in one storage apparatus to another storage apparatus.

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.

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.

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.

A storage subsystem includes: a controller; a first logical storage area corresponding to a RAID group configured by a plurality of storage devices; and a second logical storage area corresponding to a plurality of the RAID groups each configured by the plurality of storage devices, and storing a copy of data stored in the first logical storage area. In the storage subsystem, the first and second logical storage areas form a copy group, and for starting copying from the first to second logical storage area, the controller performs a mode change, from a power saving mode to a ready mode, to the plurality of storage devices configuring the plurality of RAID groups corresponding to the second logical storage area. With such a storage subsystem, the time can be reduced for activating copy-destination storage devices to which a power saving function is applied, and the copy time is thus favorably reduced.

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.
