Abstract:
A light emitting device housing having a concave part is provided therein for housing a light emitting device. Side surfaces of the concave part are each configured to be a perpendicular surface that is substantially perpendicular to a bottom surface of the concave part, and other side surfaces are each configured to be an inclined surface for reflecting light from the light emitting device toward above the light emitting device.
Abstract:
A first storage system includes a first storage area for storing data written by a computer. A second storage system includes a second storage area to which the data stored in the first storage area migrates. A third storage system includes a virtual storage area corresponding to the second storage area. An access request to the virtual storage area is converted into an access request to the second storage area to be issued. A management computer transmits, to the third storage system, an instruction to migrate the data of the second storage area to a third storage area of the third storage system based on a determination result between a value of the data migrated to the second storage area and a predetermined threshold value.

A method of manufacturing a semiconductor device includes a first step of forming a laminated substrate by laminating a plurality of semiconductor substrates, a second step of forming a concave part by etching the laminated substrate, and a third step of mounting a semiconductor element in the concave part.
Abstract:
The computer system having a storage subsystem for storing data in a logical storage extent created in a physical storage device constituted of a physical storage medium, a host computer for reading/writing data from/to the logical storage extent via a network, and a management computer for managing the storage subsystem. The management computer records components of the storage subsystem, a connection relation between the components included in a network path, a correlation between the logical storage extent and the components, and a load of each component, specifies components included in a leading path from an interface through which the storage subsystem is connected with the network to the physical storage medium, measures loads of the specified components to improve performance.
Abstract:
A storage system has a pool which is made up of a plurality of storage regions supplied by physical disks, and allocates the storage regions within this pool to volumes supplied to host computers, and cancels such allocations. When a volume addition event has occurred, a management computer forecasts, for each volume, the capacity which is to be required at a certain time point in the future, based on usage capacities acquired for each volume, calculates a non-required capacity from this capacity which has been forecast and the capacities of the storage region groups which are already allocated to the volume, decides, based on one or more non-required capacities which have been calculated, whether or not there is a storage region enough to satisfy the capacity requested for a volume which is the object of addition, and, if a positive decision result is obtained, allocates storage regions equivalent to the non-required capacity to the volume which is the object of addition.
Abstract:
In a semiconductor device 100, a light emitting device 102 is mounted on a substrate 101. A light reflection preventing film 130 for preventing a reflection of a light is formed on an upper surface of the light emitting device 102. Moreover, a plate-shaped cover 103 formed of a glass having a light transparency is disposed above the light emitting device 102, and a light reflection preventing film 140 for preventing a reflection of a light is also formed on an upper surface of the cover 103.
