Abstract: In a storage apparatus, in the case where a data block to be written to a storage medium is a zero data block containing only zero data, a zero data information memory stores zero data identification information indicating that the data block is a zero data block. A control apparatus receives a data block from an access requesting apparatus in association with a write request issued by the access requesting apparatus for writing the data block a specified number of times to a predetermined storage area of the storage medium, and when determining that the data block is a zero data block containing only zero data, sets zero data identification information in the zero data information memory, and when completing the setting of the zero data identification information, sends the access requesting apparatus a completion notice of the writing to the storage medium.

Abstract: A system creates a configuration definition table to be used for accessing a physical disk according to a host I/O request, to decrease a memory size of the configuration definition table even if common firmware is used for models with different scales. For this, a model correspondence table to show the definition of each model is provided in a configuration setup processing module, the maximum values of this model are recorded in a memory based on this content, and a memory area for each item is secured. And the actual content of the configuration definition is developed on the secured memory. Therefore even for a diversity of models, the memory size of the configuration definition table can be decreased to a size matching the model, with common firmware regardless the model.

Abstract: A RAID apparatus that at least duplicates identical data to store thus duplicated data, which, when an instruction of writing data is given, writes data to a local cache and to a mirror cache, and writes data of the local cache to a primary disk and writes data of the mirror cache to a secondary disk. When an instruction of reading out data is given, and specified data is retained in the caches, the RAID apparatus outputs valid data of the local cache or the mirror cache, while when specified data is not retained in the caches, the RAID apparatus outputs valid data of the primary disk or the secondary disk.

Abstract: A fuel pump attachment structure includes a pump support member and a cover member. The pump support member has a fuel pump support surface via which a fuel pump is to be attached to a fuel tank inside the fuel tank made of second resin. The pump support member includes an insert plate and an insert nut. The cover member is made of first resin and provided on the fuel pump support surface of the pump support member.

Abstract: An interdevice communication monitoring unit 62-1 calculates a variable timeout time (T2?T) by subtracting an elapsed time T from a predetermined fixed timeout time T2 for monitoring an intermodule communication to monitor an elapsed time of an intermodule communication. The fixed timeout time T2 is a time shorter than a predetermined interface connection check time T1 for monitoring an interface connection with a channel. When the elapsed time T of the intermodule communication exceeds the variable timeout time (T2?T), the interdevice communication monitoring unit requests a channel to separate the interface connection, and then when an end response is obtained from a control module, requests the channel for an interface reconnection and then transmits an end response.

Abstract: To surely insert a fastening member into a fuel tank by sufficiently feeding a resin to every corner of the fastening member using a simple method. An insert ring is mounted on a resin-made fuel tank body, the insert ring has seat surfaces for mounting a fuel pump thereon and boss holes formed in the seat surfaces. An insert molded body is formed by performing insert molding of the insert ring using a first resin material in a state wherein the boss holes and the seat surfaces are exposed. The insert molded body is inserted into an outer surface of the fuel tank body by insert molding using a second resin material which forms the fuel tank body.

Abstract: A disk array device having a plurality of hard disk units has a large-capacity memory mounted on a controller module which controls the whole device. The large-capacity memory has a system area managed by an OS and a cache area serving as a cache memory, and in addition, it has a table area which stores management/control information of the device and whose area size is changeable at an arbitrary instance. Therefore, it is possible to change the table area according to the state of the device in an active state without ON/OFF of a power source, so that an area not in use in the table area can be released for use as the cache memory. This makes it possible to appropriately varying the sizes of the table area and the cache area in an active state while the device is in operation, thereby realizing effective use of the large-capacity memory.

Abstract: In the present invention, for each set of blocks [#(0) to #(N?1)] storing update data, a history block [#(N)] storing an update state value, for example, a generation, time or check code, showing an update state is provided, constituting a set of management data as a check object. When writing update data on a disk, a new update state value is calculated for the same set of management data and stored in memory as update state confirmation value. The new update state value is also set as write data in the history block in the same set of management data, and the entire of the set of management data including update data and update state value are written onto a disk. The history block is read and disk write omissions are detected by comparing the update state value and the update state confirmation value stored in memory.
