    摘要: A data look-ahead control is provided to realize a high cache hit rate and improves responsiveness in an information processing system. In the data look-ahead control, when it is determined that the current input/output request is an access to a specific database that was the subject of a recent input/output request and whose I/O count exceeds a predetermined value, and it is also determined that a cache memory can be occupied to some extent and that there would be no impact on other input/output requests, data including one or more blocks (logical tracks) larger than a block that is the subject of the current I/O request are loaded to the cache memory.

    摘要: There is provided a data processing system which, from a point of view of increasing process efficiency of the entire data processing system to exhibit a maximum effect, may assign an alias device to a logic device. The data processing system of this invention comprises a host processing device (10) and a storage control device (20) connected thereto via a communication means (50), where the storage control device (20) has a deciding means for deciding, at a time of processing an I/O request of a certain base device, whether there is a need to newly assign an alias device to the base device according to a use situation of a physical device (203). When assignment is decided as necessary, the host processing device (10) is notified of such via the communication means, and the host processing device (10) newly assigns an alias device to the base device when there is the notification from the storage control device (20).

    摘要: In control method and apparatus for data transfer in an external storage subsystem, a disk unit and a control unit interposed between a host channel and a processing unit are provided and data in a variable record length supplied from the host is converted to data in a fixed record length to write it in the disk unit. Final format writing end position information for a logical track and an erase flag indicating whether the erasing is required or not are stored at a portion of a logical track control table which controls a cache memory, for each logical track. In the format writing on the cache memory, the final format writing end position information and the erase flag are updated, and when the data is written into the disk unit from the cache memory by logical track unit, the erase flag is referred and the erasing is performed if it is required. Thus, the area of erasing and the number of times of execution are minimized and the throughput of the data transfer between the processing unit and the rotating storage device is improved.

    摘要: A swash plate compressor capable of realizing an excellent sliding characteristic when a drive shaft is rotated at high speed, and a high refrigerating capacity when the drive shaft is rotated at low speed, has a release passage for communication between a crank chamber and a suction chamber. The release passage includes a first passage communicated to an oil rich region, in the crank chamber, and a second passage communicated to an oil poor region, in which lubricating oil is small in quantity, in the crank chamber. A valve mechanism that increases an opening ratio of the first passage with respect to the release passage, as a rotational speed of a drive shaft increases, and increases an opening ratio of the second passage with respect to the release passage, as the rotational speed of the drive shaft decreases.
