To provide a fine nickel powder for an internal electrode paste of an electronic component, the nickel powder obtained by a wet method and having high crystallinity, excellent sintering characteristics, and heat-shrinking characteristics. The nickel powder is obtained by precipitating nickel by a reduction reaction in a reaction solution including at least water-soluble nickel salt, salt of metal nobler than nickel, hydrazine as a reducing agent, and alkali metal hydroxide as a pH adjusting agent and water; the reaction solution is prepared by mixing a nickel salt solution including the water-soluble nickel salt and the salt of metal nobler than nickel with a mixed reducing agent solution including hydrazine and alkali metal hydroxide; and the hydrazine is additionally added to the reaction solution after a reduction reaction initiates in the reaction solution.

An I/O result receiving unit receives, from a storage device control unit, a result of I/O to a logical device with respect to an I/O request from an I/O control unit, a format target determining unit considers a failed track to be a format target when the failed track corresponds to a control area or an unallocated area, and a format requesting unit requests the storage device control unit to format a storage area of storage devices which corresponds to a page allocated to the failed track having been considered a format target.

Storage control apparatus and recovery method of a failed track

A server including a memory unit, a processor unit, and a storage device, wherein the memory unit has: a CM; an SM which stores management information; and a log buffer for storing log data indicating contents of change to the CM and the SM. The storage device has a log chunk for storing the log data, and the processor unit is configured to: store target data corresponding to an I/O request in the CM; generate log data of contents of change with respect to the CM and the SM, and to store the pieces of the generated log data in the log buffer; write a plurality of pieces of log data stored in the log buffer into the log chunk; and transmit, after all of the pieces of log data corresponding to the I/O request are written into the log chunk, a response of good to a request source.

The present invention provides a silver powder that has an appropriate viscosity range at the time of paste production, can be easily kneaded, and prevents flake occurrence. The silver powder has a dibutyl phthalate absorption amount, measured by a method of JIS-K6217-4, of 7.0 to 9.5 ml/100 g, and has an oil absorption profile at the time of measurement of the absorption amount, having two peaks, or one peak having a half width of not more than 1.5 ml/100 g.

Silver powder

Provided is a silver powder which has an appropriate viscosity range at the time of paste production, can be easily kneaded, and prevents the occurrence of flakes. The silver powder to be used has a specific surface area ratio SA/SAof 0.5 to 0.9, wherein SAis a specific surface area measured by the BET method, and SAis a specific surface area calculated from a mean primary-particle diameter Dmeasured with a scanning electron microscope. Furthermore, the silver powder preferably has a degree of aggregation of 1.5 to 5.0, the degree being obtained in such a manner that a volume median diameter Dmeasured by laser diffraction scattering is divided by the foregoing Ds.

One processor core of a plurality of processor cores that are included in a multi-core processor that processes a request from an external device detects a prescribed event, specifies a sub resource that is assigned to the one processor core based on the resource management information that indicates a sub resource of a plurality of sub resources that are included in a physical resource and a processor core that is assigned to the sub resource, and executes a reboot based on the specified sub resource.

Request processing system provided with multi-core processor

Even if each processor core uses the same logical address, a processing-target program corresponding to each processor core can be selected. A logical address of multiple address mapping tables is set to a same logical address in correspondence with an embedded OS program or a RAID management program, and a physical address is set to a different physical address in correspondence with the actual storage destination of an embedded OS program or a RAID management program. Each processor core, on start-up, uses a self address mapping table to execute address mapping processing with each processor core based on the same logical address, selects an embedded OS program or a RAID management program according to the physical address obtained in the address mapping processing, and executes processing according to the selected program.

Multi-core address mapping for selecting storage controller program

A storage system has a single processor that operates in a multitasking operating system environment. An operation time manager adjusts the balance between processing time proportions for interrupt processing and task processing requested of the storage system internally and externally so that those processing time proportions become within respective predetermined ranges.

System for monitoring time proportion for interrupt or task processing with restriction placed in subsequent monitoring time period when allowable time proportion is exceed
